Problem with Service Brakes

Jun 15, 2017 - Gainesville, FL - Service Brakes
ABS LIGHT CAME ON. DIAG CODE: C1391. ABNORMAL LEAK IN ACCUMULATOR. THIS PROBLEM IS SIMILAR TO A RECALL ON PRIUS 2010 FOR ABS BRAKE ISSUE. HOWEVER, TOYOTA SAID THAT MY PRIUS IS NOT PART OF THE RECALL. I WOULD LIKE TO REQUEST TOYOTA TO FIX THIS PROBLEM FOR MY PRIUS 2010 SO THAT I CAN SAFELY DRIVE THIS CAR.

BRAKES TURNED TO MUSH - PEDAL WENT ALL THE WAY TO THE FLOOR WITH ALMOST ZERO STOPPING POWER. SOUNDS LIKE A SIMILAR RECALL FROM 2013 OR SO. GOING 45 MPH (SPEED LIMIT) ON A BUSY 4 LANE HGHWAY APPROACHING STOPLIGHT AND SLOWING TRAFFIC FOR RED LIGHT AT INTERSECTION OF ANOTHER 4 LANE ROAD. BRAKES MOSTLY UNRESPONSIVE. ALMOST WENT THROUGH INTERSECTION AND NARROWLY MISSED HITTING A SLOWING CAR. BRAKING DID NOT ENGAGE PER USUAL ACTIVATION POSITION AND PEDAL WENT TO THE FLOOR INSTEAD. CAR WAS JUST SERVICED A WEEK AGO FOR UNRELATED RECALL ITEM. CAR HAS BEEN MAINTAINED DILIGENTLY SINCE NEW PURCHASE IN 2009, GETTING ALL RECALLS SERVICED PROMPTLY. MAYBE THE RANGE OF VINS IN THE OLDER RECALL WAS NOT WIDE ENOUGH?

WHEN DRIVING OVER BUMPY OR ROUGH SURFACES OR POT HOLES, WHILE APPLYING THE BRAKES, THE BRAKES OFTEN SEEM TO STOP WORKING. AND THE CAR SEEMS TO HAVE A LITTLE BOOST FORWARD. IT HAPPENS WHEREVER THE ROAD SURFACE HAS BUMPY AREAS ON STRAIGHTAWAYS OR CURVES. AND MOSTLY WHEN APPLYING LIGHT PRESSURE TO THE BREAK, LIKE SLOWING FOR AN UPCOMING TURN. IT HAS BEEN HAPPENING SINCE I GOT THE CAR IN 2013. I HAVE TAKEN IT TO A MECHANIC, BUT THEY COULDN'T FIND THE PROBLEM. THIS HAS HAPPENED MANY TIMES OVER LAST 3 1/2 YEARS.

I AM THE ORIGINAL OWNER OF A 2010 PRIUS. WITHIN THE FIRST MONTH, I CONTACTED TOYOTA, COMPLAINING OF THE BRAKES, WHICH WERE NOT CONSISTENTLY SMOOTH. IN GENERAL, THE BRAKES WORK FINE, BUT IF I HIT A BUMP OR DITCH, THE BRAKES SUDDENLY STOP WORKING FOR A SPLIT SECOND, AND THE CAR FEELS LIKE IT IS LURCHING FORWARD, BEFORE THE BRAKES SUDDENLY START WORKING AGAIN. TOYOTA SERVICE WAS NEVER ABLE TO "REPRODUCE" THE PROBLEM, AND EVENTUALLY I GAVE UP. A COUPLE YEARS AGO, THE CAR WAS RECALLED FOR THIS PROBLEM, AND I BROUGHT THE CAR IN TO BE FIXED. UNFORTUNATELY, THE RECALL WORK HAS NOT REMEDIED THE PROBLEM. THE BRAKES STILL SEEM TO OCCASIONALLY MALFUNCTION WHEN THE CAR DRIVES OVER A ROUGH PATCH. TOYOTA SEEMS TO BELIEVE THE PROBLEM HAS BEEN SOLVED, BUT IT HAS NOT BE SOLVED. THERE IS NO DIFFERENCE SINCE THE RECALL.

THIS AFTERNOON, MY WIFE WAS DRIVING DOWN A TWO LANE, PAVED STREET AT ABOUT 25 MPH. THE STREET HAS A SLIGHT DECLINE AND SHE BEGAN TO APPLY THE BREAKS TO SLOW DOWN SLIGHTLY. JUST A SECOND OR TWO LATER, SHE HIT A SMALL BUMP IN THE ROAD AND THE CAR ACCELERATED (WHILE SHE HAD HER FOOT ON THE BREAK) FOR A FRACTION OF A SECOND. WE DIDN'T HEAR THE SOUND OF THE ENGINE REVVING. THANKFULLY, THERE WERE NO OTHER CARS ON THE ROAD AT THIS TIME AND THERE WAS TIME TO PRESS THE BREAK AGAIN. BASED ON LOOKING AROUND ONLINE, MANY PEOPLE HAVE REPORTED SIMILAR ISSUES (HTTP://WWW.CONSUMERREPORTS.ORG/CRO/NEWS/2010/02/TOYOTA-ADDS-2010-PRIUS-BRAKING-PROBLEM-TO-THE-LIST-RECALL-POSSIBLE/INDEX.HTM).

WHEN I AM COMING TO A STOP (BRAKING NORMALLY) AND HIT A BUMP, THE CAR SURGES SLIGHTLY AND THE BRAKES BECOME LESS RESPONSIVE. IT FEELS LIKE I'M FIGHTING THE ENGINE AS IT ACCELERATES AND I'M TRYING TO BRAKE AGAINST IT. RELEASING THE BRAKE AND ATTEMPTING AGAIN SEEMS TO BE A SOLUTION, BUT I OFTEN DON'T HAVE TIME BEFORE REACHING THE INTERSECTION I'M APPROACHING. THIS CONSISTENTLY HAPPENS IN TWO PLACES IN MY DAILY COMMUTE WITH A SLIGHT BUCKLE IN THE ROAD APPROACHING AN INTERSECTION ON CITY STREETS AND COUNTY ROADS.

DRIVING DOWN HIGHWAY AT POSTED SPEED LIMIT (75MPH), I TRIED TO SLOW DOWN DUE TO TRAFFIC AND NOTICED MY CARS ABILITY TO BRAKE WAS SEVERELY COMPROMISED. I THEN NOTICED MY CARS BRAKES, ABS, MASTER WARNING AND VSC LIGHTS HAD CAME ON. GIVEN THAT MY CAR HAS 103K MILES ON IT, I FIGURED IT IS TIME FOR A BRAKE PAD SERVICE. WITH THE LIMITED BRAKING ABILITY, I DECIDED TO MAKE THE SHORT DRIVE TO THE TOYOTA DEALER FOR BRAKE SERVICE. AFTER THE DEALER INSPECTED MY CAR, A REPRESENTATIVE TOLD ME THAT IT IS NOT THE BRAKE PADS THAT ARE CAUSING THE LIGHTS IN YOUR DASH TO GO ON BUT RATHER THE BRAKE BOOSTER. THEY ADVISED ME THAT IT IS NOT RECOMMENDED THAT I DRIVE THE CAR ANYMORE UNTIL THE ISSUE IS REMEDIED BY REPLACING THE BRAKE BOOSTER AT A COST OF OVER 2K. I HAD TO ALSO INCUR THE COST OF A RENTAL SINCE THE BOOSTER WAS NOT IN STOCK AND WOULD TAKE OVER THE WEEKEND TO RECEIVE. I WAS TAKEN ABACK BY THE TOTAL COST OF THE SERVICE BUT HAD NO CHOICE AND PROCEED TO GET IT REPAIRED. UPON RECEIVING MY CAR A FEW DAYS LATER, I DROVE TO WORK AND UPON MY RETURN HOME, THE ISSUE REPEATED ITSELF WITH ALL THE LIGHTS ON THE DASH LIGHTING UP AND THE CARS BRAKING ABILITY WAS AGAIN COMPROMISED. EXTREMELY IRATE, I DROVE DIRECTLY TO THE DEALER AND UPON INSPECTING THE CAR THEY TOLD ME THAT IT IS NOW THE ACCUMULATOR THAT NEEDS TO BE REPLACED. THIS TIME THE DEALER ABSORBED THE COST OF OVER 3K TO REPLACE IT. I RESEARCHED THE INTERNET FOR ANY KNOWN RECALLS AND FOUND THE ISSUE WAS BEING ADDRESSED BY TOYOTA WITH A RECALL HOWEVER MY CARS VIN WAS NOT PART OF IT. IT IS MY HOPES THAT YOU MAKE TOYOTA AWARE OF THE SAFETY ISSUE AND INITIATE A RECALL ON ALL 2010 PRIUS MODELS AND NOT JUST SOME. I WOULD ALSO LIKE TO GET THE COST I INCURRED WITH THIS SAFETY ISSUE REIMBURSED AT SOME POINT.

ABS ACTUATOR WITH MASTER CYLINDER ASSEMBLY HAS INTERNAL LEAK. ASSEMBLY DOESN'T HOLD PRESSURE AND ACTUATOR MOTOR CONTINIOUSLY WORKING IN ORDER TO CREATE THE PRESSURE. DUE TO THIS PROBLEM BRAKES ARE NOT OPERATE AS PROPERLY. IT TAKES MORE STRENGTH TO PUT ON THE PEDAL TO STOP VEHICLE. I ALSO NOTICED THAT DURING EMERGENCY BRAKING NOT ALL WHEELS WERE INVOLVED EQUALLY. DUE TO THIS PROBLEM BRAKING DISTANCE SIGNIFICANTLY INCREASED. I HAVE 3 INSTRUMENT CLUSTER ERROR LIGHTS TURNED ON DUE TO THIS PROBLEM: "BRAKE", LIGHT WITH VEHICLE ON SLEEPY ROAD, AND LIGHT WITH "!" SIGN. I FOUND THAT THERE ALREADY WAS RECALL FOR SAME 2010 YEAR TOYOTA PRIUS UNDER TMS-NTC-13178 OF JULY 23, 2013, TOYOTA RECALL NAME D0H, BUT MY VEHICLE IS NOT COVERED. I KINDLY ASK YOU TO INVESTIGATE IF MY CAR ELIGIBLE TO PARTICIPATE IN THIS RECALL CAMPAIGN, SINCE SEEMSTHAT THIS CAR WERE ASSEMBLED WITH SAME UNRELIABLE PARTS.

THE BRAKE ACTUATOR FAILED ON OUR 2010 PRIUS III MANUFACTURED IN OCTOBER 2010. TOYOTA IS COVERING PROBLEMS WITH THIS SAME BRAKE ACTUATOR FOR 2010 PRIUS MANUFACTURED BETWEEN MARCH 2009 AND EARLY OCTOBER 2009. MY VIN DID NOT FALL INTO THAT DATE RANGE EVEN THOUGH MINE WAS MANUFACTURED IN OCTOBER 2009, SO THE BRAKE DEFECT SHOULD BE EXTENDED TO BEYOND THE EARLY OCTOBER 2009 MANUFACTURED DATE. THE SYMPTOMS TO THIS PROBLEM WERE THE BRAKE, ABS AND TRACTION CONTROL WARNING LIGHTS CAME ON, NO REGENERATIVE BRAKING AND THE BRAKING DISTANCE INCREASED.

I APPLIED BRAKE ON A RED LIGHT WHICH IS AS USUAL FOR ME AND I NOTICED CAR DIDN'T SLOW DOWN AND KEPT MOVING PAST THE RED LIGHT. IT HAS HAPPENED BEFORE AND THE IT HAPPENS ON UNEVEN AND EVEN ON MINOR POTHOLES. THE BRAKES ON THE SMALL BUMPS AND MINOR UNEVEN ROADS COMPLETELY LOOSE TRACTION OF THE TIRES AND CAR EVEN FASTER WITH THE BRAKES ON WHEN TRYING TO STOP OVER MINOR UNEVEN ROADS. MECHANIC SAID IT'S OVERSENSITIVE ANTI LOCKING BRAKES THAT CUT OFF THE BRAKE POWER EVEN WHEN IT DETECTS MINOR DISTURBANCE IN THE SENSORS.

I HAVE A 2010 TOYOTA PRIUS. WHEN TRYING TO SLOW DOWN, ANY TIME A BUMP IS HIT, (OR A POTHOLE) THE BRAKING POWER SIGNIFICANT DECREASES . THIS GREATLY INCREASES THE STOPPING DISTANCE AND IS VERY SCARY IN TRAFFIC AND IN WINTER DRIVING. IS THIS A PROBLEM? I CALLED TOYOTA EARLIER FOR THE SAME ISSUE AND THEY TOLD ME THAT THIS IS NORMAL AND THIS OCCURS BECAUSE ONLY ONE TIRE IS HITTING THE POTHOLE OR BUMP+ IT IS VERY SCARY AND I HAVE TO LEAVE A LOT OF SPACE AHEAD OF MY CAR.

HELLO. I RECENTLY STARTED TO EXPERIENCE AN ISSUE WITH MY VEHICLE. MY BRAKES STARTED TO MAKE SOME KIND OF UNUSUAL NOISES EVERY TIME I PRESS ON THEM. I'VE NEVER HAD THAT BEFORE AND I SERVICE MY CAR PRETTY OFTEN. I WENT TO AUTHORIZED TOYOTA DEALERSHIP AND THEY TOLD ME THERE WAS A COMPUTER ISSUE AND THEY FIXED IT FOR $110. IT CONTINUED TO MAKE NOISES AND ALL OF THE SUDDEN IT BEGAN SHOWING ABS/BRAKE/VSC LIGHTS ON MY CAR DASHBOARD EITHER WHILE I WAS DRIVING OR BEING IN THE +PARK+ MODE. AT THE SAME TIME MY BRAKES STOPPED WORKING WELL WHILE DRIVING WHEN THE ABS/BRAKE/VSC LIGHTS WERE ON. I CHECKED THE CODE OF THE ERROR THROUGH THE CAR COMPUTER AND IT SHOWED ME +C1391+. I WENT TO THE DEALERSHIP AGAIN AND THEY DID ANOTHER CHECK AND THIS TIME THEY FOUND THAT BRAKE MASTER CYLINDER/BOOSTER/ABS ASSEMBLY NEEDS TO BE REPLACED WITH $3,170 PRICE. I ATTACHED HERE THE PAPER THAT MY TOYOTA PRIME DEALERSHIP LOCATED HERE IN SACO, ME GAVE ME. I+VE BEEN READING A LOT ABOUT IT ONLINE AND PEOPLE WITH THE SAME TYPE OF HYBRID VEHICLES HAVE EXPERIENCED IT. I THINK TOYOTA NEEDS TO LOOK INTO THE ISSUE AND ACKNOWLEDGE THAT IT IS A COMMON PROBLEM IN THEIR HYBRID VEHICLES. I SERVICE MY CAR ALL THE TIME, I DO OIL CHANGE AND CHECK ALL THE SYSTEMS VERY THOROUGHLY, SO I DON+T UNDERSTAND WHY WE, CONSUMERS, HAVE TO PAY THAT BIG OF A PRICE FOR THE CAR REPAIR. I HOPE YOU CAN LOOK INTO THE ISSUE AND HELP ME (AND TO ALL OTHER CAR OWNERS) TO RESOLVE THIS KIND OF ISSUE. THANK YOU.

I RECENTLY PURCHASED A TOYOTA 2010 PRIUS AND FOUR DASH WARNING LIGHTS APPEARED THE DAY AFTER I PURCHASED IT WHEN I TURNED THE CAR ON IN THE MORNING. THE LIGHTS STAY ON FOR HOURS TO DAYS AND GO OFF FOR SIMILAR AMOUNT OF TIME. WHEN THE LIGHTS ARE ON THE BRAKES ARE MUCH LESS RESPONSIVE AND THE BRAKING ACTION DOES NOT CHARGE THE BATTERIES AS MUCH, NEVER MORE THAN 25% OF CHARGING POTENTIAL. THE PROBLEM WAS DIAGNOSED AS A PROBLEM WITH ACCUMULATOR IN THE BRAKE SYSTEM. I PERFORMED A SEARCH ONLINE AND FOUND THAT THERE IS A RECALL FOR SUCH PROBLEM, BUT MY VEHICLE WAS PRODUCED A MONTH AFTER THE DATE OF PRODUCTION THAT WOULD QUALIFY FOR THIS RECALL. I WILL A PDF COPY OF THE RECALL I'M REFERRING TO.

I WENT TO START THE PRIUS AFTER WORK, AFTER I PRESSED THE START BUTTON, SEVERAL ALARMS WENT OFF ON THE MAIN PANEL. ALARMS INCLUDED THE MASTER ALARM, ABS, BRAKE, CHECK ENGINE, AND AN INCESSANT BEEPING. THERE WAS ALSO A REPETITIVE SOUND COMING FROM UNDER THE HOOD THAT SOUNDED LIKE THE BRAKING SYSTEM WAS TRYING TO BUILD PRESSURE, BUT WAS NOT SUCCESSFUL. I TOWED THE VEHICLE TO THE DEALERSHIP AND THEY DIAGNOSED THIS AS THE MASTER BRAKE BOOSTER ASSEMBLY. THE QUOTE WAS $2500 FOR THE PART, AND $500 IN LABOR. THEY STARTED WORK ON THE VEHICLE, THEN CALLED AND SAID THAT THEY WOULD HAVE TO REPLACE THE ACCUMULATOR AS WELL, EVEN THOUGH IT WAS ALREADY REPLACED DURING THE ORIGINAL RECALL. THEY CONTACTED TOYOTA CORPORATE WHO PAID FOR THE ACCUMULATOR, BUT WOULD NOT COVER THE ADDITIONAL LABOR TO INSTALL THE ACCUMULATOR. THE TOTAL BILL WAS $3900. THIS SEEMS LIKE A COMMON PROBLEM WITH THE PRIUS FAMILY. MY CAR HAD APPROXIMATELY 92,000 MILES.

BRAKE SYSTEM FAILURE WHILE DRIVING ON SUBURBAN STREET. MASTER CYLINDER, ASSEMBLY AND BOOSTER REPLACEMENT. ALL CORRESPONDING WARNING CAME ON. WAS ABLE TO DRIVE TO DEALER. THIS IS THE EXACT PROBLEM THAT INCITED THE RECALL FOR NITROGEN LEAKING INTO THE BRAKE SYSTEM IN SOME PRIUS MADE IN 2010 (82,000). COST OF $3200. INCIDENTALLY, BRAKE FLUID WAS FLUSHED AND CHANGED AT 60,000 AND THEN AGAIN AT 75,000. THE REASON, STATED FROM THE DEALER IS THAT MAINTENANCE WAS RESPONSIBLE FOR THE FAILURE. PRIORITY TOYOTA OF SPRINGFIELD WAS THE ONLY ONE DURING THE MAINTENANCE AND I FOLLOWED THEIR RECOMMENDED ADVICE FOR THE 2 BRAKE FLUID FLUSHES AND REPLACEMENT.

I AM EXPERIENCING A RESURGENCE OF THE ACCELERATION WHILE BRAKING PHENOMENON THAT WAS THE BASIS OF THE 2010 RECALL. WE HAD THE CAR FIXED AT THE TIME OF THE RECALL. THE INCIDENTS RELATE TO WHEN I AM BRAKING AND HAPPEN TO GO OVER A BUMP OR HIT A POTHOLE. AS I AM BREAKING THE CAR SUDDENLY ACCELERATES FORWARD AND YOU HAVE TO KEEP BREAKING HARDER TO KEEP FROM HAVING THE CAR GET AWAY FROM YOU. IT IS NOW HAPPENING ALMOST CONSISTENTLY. AFTER CALLING THE LOCAL TOYOTA DEALER AND THE GENERAL TOYOTA NUMBER, I FIND OUT THAT THEY ARE NOT WILLING TO APPLY THE SAME FIX AS THEY DID IN 2010. I AM NOW FORCED TO TAKE THE CAR IN AND HAVE IT DIAGNOSED AND DON'T KNOW WHAT THEY WILL CHARGE ME FOR THAT. THEN TOYOTA SAID I COULD CALL THEM BACK TO SEE IF THERE IS ANYTHING THEY CAN DO I DON'T UNDERSTAND WHY THEY DON'T HAVE TO STAND BY A FIX THAT IS NOT RELATED TO WEAR AND TEAR BUT RATHER A MALFUNCTION IN THE WAY THEY BUILT THE CAR. IT SHOULD NEVER BE RIGHT TO HAVE A CAR ACCELERATE IF ONE IS BRAKING. THE ONLY DAMAGE TO DATE HAS BEEN A GLARE FROM A CONSTRUCTION WORKER WHO WAS TELLING ME TO STOP ONLY TO SEE THE CAR LURCH TOWARD HIM.

I WAS IN A PARKING STRUCTURE GOING APPROXIMATELY 15 MPH WHEN I REMOVED MY FOOT FROM THE ACCELERATOR TO PRESS THE BRAKE. BEFORE I COULD GET MY FOOT TO THE BRAKE, THE CAR QUICKLY ACCELERATED. IT TOOK AT LEAST TWO ATTEMPTS AT PUSHING THE BRAKE PEDDLE BEFORE THE CAR CAME TO A STOP. AND, TO BE HONEST, THE GUARDRAIL THE CAR HIT HELPED ACTUALLY STOP THE VEHICLE. IT WAS TOTALLY UNEXPECTED AND EXTREMELY SCARY. IN HINDSIGHT, I SHOULD HAVE SUSPECTED THAT THERE MAY BE A PROBLEM WHEN I NOTICED THAT SOMETIMES WHEN APPLYING THE BRAKES TO COME TO A STOP THERE WOULD BE A FEELING OF THE BRAKES SLIPPING AND THE CAR LURCHING FORWARD A BIT. THE DEALERSHIP HAD THE CAR TOWED IN TO GET CHECKED OUT, AND I HAVE BEEN TOLD THAT THEY WILL NOTIFY TOYOTA. IN THE MEANTIME I AM CONCERNED ABOUT THE SAFETY OF THIS CAR!

I HAVE DRIVEN PEOPLE FOR A LIVING FOR OVER 30 YEARS. I BOUGHT A PRIUS BECAUSE OF FUEL COSTS. A MONTH AGO WHILE TRANSPORTING PASSENGERS, MY POWER BRAKES GO OUT AND MY DASH LIGHTS UP WITH ABS,BRAKE, & TRACTION CONTROL WARNING LIGHTS. I TAKE IT TO THE TOYOTA DEALER WHO CHARGES ME $111 TO TELL ME I HAVE A BRAKE PROBLEM AND THAT IT WILL COST $4418 TO FIX IT. CODE # C1391; THEY RECOMMEND REPLACING THE MASTER CYLINDER; AND BOOSTER PUMP ASSEMBLY SAYING THERE IS AN ABNORMAL LEAK DOWN OF THE BRAKE ACCUMULATOR. THIS IS INSANE. I CANNOT AFFORD TO FIX IT AND MUST CONTINUE TO WORK TO LIVE; THEREFORE DRIVING ABOUT 200 MILES/DAY WITH HYDRAULIC ONLY BRAKES. MY RESEARCH INDICATES THERE WAS A MAJOR RECALL FOR THIS EXACT PROBLEM ON THE 2010 MODEL. THE DEALERSHIP AND TOYOTA CORPORATE BOTH SAY MY VEHICLE WAS NOT PART OF THE RECALL. I FEEL AS THOUGH IT SHOULD BE SINCE, OBVIOUSLY, THE PROBLEM HAS NOT BEEN SOLVED. I AM NOT ALONE, AS MANY OWNERS ON PRIUSCHAT HAVE THE SAME PROBLEM. THIS IS A MAJOR SAFETY CONCERN TO NOT ONLY MYSELF, OTHER VEHICLES OR PEDESTRIANS, BUT ALSO MY PASSENGERS. AN EXPANDED RECALL IS NECESSARY AND WARRANTED. ANYTHING YOU CAN DO WILL HELP AND MAKE US ALL SAFER. .

DESIGN FLAW....LOSS OF BRAKE FUNCTION DURING BRAKING EVENTS WHILE GOING OVER BUMPS AND POTHOLES (LOWER SPEEDS <30MPH). I BELIEVE THE ROOT CAUSE IS THE TRANSITION BETWEEN REGENERATIVE BRAKING AND HYDRAULIC BRAKE. I ALWAYS FEEL UNSAFE DURING BRAKING EVENTS, AND ALWAYS HAVE TO BE PROACTIVE AND CALCULATE THE DISTANCE IN FRONT OF ME TO ACCOMMODATE THE LOSS IN STOP DISTANCE . VERY UNCOMFORTABLE FEELING!

ONCOMING CAR STOPPED AT TRAFFIC LIGHT WHILE I WAS PROCEEDING STRAIGHT IN THE OPPOSITE DIRECTION. THE ONCOMING CAR THEN MADE A LEFT TURN ACROSS THE ROAD IN FRONT OF ME. I STARTED A TURN TO THE RIGHT ASSUMING THAT THE OTHER CAR WOULD SEE ME AND STOP. AT THE SAME TIME I HIT MY BRAKES. MY CAR SEEMED VERY SLOW TO DECELERATE. I NOW REALIZE THAT CAR BRAKES CAN GIVE MUCH MORE SIGNIFICANT STOPPING. AT THE TIME, BECAUSE OF MY TRAINING AS MILITARY AND AIRLINE PILOT, I STAYED ON THE BRAKES AND DID NOT PUMP THEM. IN RETROSPECT, PUMPING THE BRAKES MIGHT HAVE GOTTEN THEM TO WORK. THE ANTI-SKID SYSTEM SEEMED TO BE INEFFECTIVE. I STRUCK THE OTHER CAR AT ITS RIGHT FRONT WHEEL. MY AIRBAG WORKED WONDERFULLY, BUT MY CAR WAS TOTALED. AS NO PERSON WAS HURT, THE POLICE WERE UNINTERESTED. THE ACCIDENT IS ON FILE WITH RIVERSIDE COUNTY SHERIFF'S OFFICE AS FILE# MV142810251. THE DATE WAS 10-8-2014.

ON 05/25/2016 AT ABOUT 9AM, WHILE IN MOTION AT A RATE OF SPEED APPROX 25 MPH ON A STREET DURING CONSTRUCTION (DON'T KNOW IF THE BUMPY ROAD HAD ANYTHING TO DO WITH IT), THE CHANGE OIL SOON LIGHT APPEARED AND SECONDS LATER ALL THE LIGHTS ON THE DASH CAME ON WITH THE MESSAGE TO CHECK THE "CHECK HYBRID SYSTEM" . I TRIED TO STOP THE VEHICLE AND IT KEPT ACCELERATING. I PRESSED ON THE BREAKS REALLY HARD AND THE TRACTION CONTROL LIGHT KEPT FLASHING ON AND OFF LIKE CRAZY BUT IT BARELY HAD ANY IMPACT. ALTHOUGH THE VEHICLE SLOWED, IT DID NOT COME TO A FULL STOP. I ENDED UP HITTING THE VEHICLE IN FRONT OF ME. THANK GOD IT WAS A TRUCK AND AS ABLE TO STOP THE CAR FROM MOVING FURTHER OR I COULD OF ENDED UP IN THE MIDDLE OF AN INTERSECTION. AFTER THE COLLISION, THE CAR WOULD NOT STOP ALTHOUGH THE PARK BUTTON WAS PRESSED AND LIGHT WAS ON. I EVEN TRIED TURNING OFF THE VEHICLE AND THE VEHICLE STAYED ON AND IN DRIVE. I ENDED UP IN THE HOSPITAL AND DON'T KNOW HOW IT EVENTUALLY GOT TURNED OFF BUT THAT WAS VERY FRIGHTENING. I HAD MY CHILDREN IN THE CAR. ON IMPACT, THE SEAT BELTS DID NOT EVEN TIGHTEN.

WHILE DRIVING HOME FROM WORK, THE BRAKES WENT OUT ON MY TOYOTA PRIUS AND THE WARNING LIGHTS FOR ABS, TRACTION CONTROL, AND BRAKES ALL CAME ON. I STILL HAD A SMALL AMOUNT OF BRAKE PEDAL LEFT AND THE EMERGENCY BRAKE CONTINUED TO WORK. WHEN THE TOYOTA DEALER DIAGNOSED THE PROBLEM TODAY, THEY SAID THAT IT WAS A $3500 BRAKE BOOSTER AND THAT IT WAS NOT COVERED UNDER RECALL OR WARRANTY. THE SYMPTOMS, THE WARNING LIGHTS, AND THE RESULTS ALL MATCH A PREVIOUS TOYOTA RECALL (D0H) EXACTLY, YET THEY WILL NOT INCLUDE MY CAR UNDER THE RECALL BECAUSE MY VIN IS NOT PART OF THE ORIGINAL RECALL. THEY'RE LUCKY I WASN'T PHYSICALLY INJURED IN ACCIDENT CAUSED BY THIS. I SUGGESTED TO THEIR CUSTOMER SERVICE REP THAT MAYBE MY CAR SHOULD BE INCLUDED IN THE RECALL, BUT THEY DID NOT AGREE.

I WAS DRIVING MY VEHICLE AT ABOUT 35 MPH ON A TWO LANE, HILLY ROAD. SUDDENLY, THE ABS AND WARNING LIGHTS STARTED FLASHING, AND THERE WAS A LOUD BEEPING NOISE. I PRESSED THE BRAKE PEDAL, AND THERE WAS NO RESPONSE. SINCE I WAS TRAVELING UPHILL, I SLOWED AND THEN USED MY EMERGENCY BRAKE TO COME TO A COMPLETE STOP. AFTER THE VEHICLE WAS TOWED TO A TOYOTA DEALER AND DIAGNOSED, I WAS INFORMED THAT THERE WAS AN INTERNAL LEAK IN THE HYDRAULIC UNIT OF THE BRAKING SYSTEM, AND THAT THE ABS PUMP MODULE AND BRAKE MASTER CYLINDER NEEDED REPLACEMENT. THIS WAS A VERY SIMILAR ISSUE TO A RECALL OF OTHER 2010 TOYOTA PRIUS VEHICLES, BUT THE RECALL DOES NOT APPLY TO MY VIN NUMBER. TOYOTA CLAIMS THAT THE PROBLEM WAS "REMEDIED" BEFORE MY VEHICLE WAS PRODUCED EVEN THOUGH ONE OF MY TROUBLE CODES IS THE SAME AS THE TROUBLE CODE REFERRED TO IN THE RECALL.

DRIVER MADE A SUDDEN STOP TO AVOID AN ACCIDENT ON 2/16/15, ENGAGING THE BRAKES. AFTERWARD THE BRAKES ALTERNATED BETWEEN BEING HARD TO PUSH AND BEING SOFT TO PUSH. DRIVER PARKED THE VEHICLE 5 MINUTES LATER. THE NEXT TIME THE CAR WAS TURNED ON(APPROXIMATELY 60M LATER), THE CAR BEGAN BEEPING AND SHOWING THREE ERROR LIGHTS - ABS, (!), AND THE TRACTION CONTROL SYMBOL. AFTER RUNNING DIAGNOSTICS, THE DRIVER WAS TOLD BY A MECHANIC THAT THE PROBLEM SOUNDED EXACTLY LIKE A PREVIOUSLY ISSUED RECALL (TCP-D0H); HOWEVER, TOYOTA HAS INDICATED THAT OUR MODEL IS OUTSIDE THE SCOPE OF THEIR RECALL. GIVEN THAT WE HAVE THE SAME MAKE/MODEL/YEAR CAR AS THE RECALL AND THE SAME ISSUE DESCRIBED, THE SITUATION IS HIGHLY SUSPECT. IN ADDITION TO INSURING MY OWN FAMILY'S SAFETY, I'M HOPING TO MAKE SURE THIS POTENTIALLY DANGEROUS BRAKE ISSUE ISN'T MORE WIDESPREAD THAN TOYOTA HAS ADMITTED.

AS I WAS DRIVING, I NOTICED THAT WHEN I PRESSED ON THE BRAKES, THE CAR WOULD JERK FORWARD BEFORE COMING TO A STOP. ONCE STOPPED (BUT STILL TURNED ON), THE CAR MADE A BUZZING NOISE I HAD NEVER HEARD BEFORE. NO WARNING LIGHTS CAME ON, AND THE BRAKES DID NOT SQUEAK. AN HOUR LATER, MY HUSBAND DROVE THE CAR HOME FOR ME (I RODE WITH A FRIEND), AND HE REPORTED THAT WARNING LIGHTS CAME ON AND THE BRAKES DID NOT WORK PROPERLY. IN ORDER FOR THE BRAKES TO WORK, HE HAD TO PRESS VERY HARD ON THEM AND ALSO ALLOW MUCH MORE DISTANCE FOR THE CAR TO STOP. HE COULD HAVE EASILY CRASHED INTO THE BACK OF ANOTHER VEHICLE. HE TOOK THE CAR TO THE TOYOTA DEALERSHIP AND WAS INFORMED THE BRAKE BOOSTER ASSEMBLY WOULD HAVE TO BE REPLACED. THIS IS THE SAME COMPLAINT AS A 2010 PRIUS RECALL, BUT MY VIN NUMBER WAS NOT INCLUDED IN THE RECALL, SO I DID NOT RECEIVE A NOTICE IN THE AIL. ALSO, WE HAD TO PAY $3008 TO HAVE THE BRAKE BOOSTER ASSEMBLY REPLACED. THE CONSUMER REFERENCED RECALL # 13V235000. UPDATED 02/11/16.

WHILE DECELERATING DUE TO APPLICATION OF THE BRAKE PEDAL IF THE VEHICLE ENCOUNTERS A POTHOLE OR OTHER DEEP ROAD IMPERFECTION THE BRAKING CUTS OUT AND THE VEHICLE RESUMES COASTING IMMEDIATELY EVEN THOUGH THE BRAKE PEDAL IS DEPRESSED. HARDER APPLICATION OF THE BRAKE PEDAL IS NECESSARY TO RESUME VEHICLE BRAKING. SUBSEQUENT BRAKING POWER IS MUCH REDUCED COMPARED TO NORMAL BRAKING AND SIGNIFICANTLY HARDER BRAKE PEDAL PRESSURE IS NECESSARY. NORMAL BRAKING MAY BE REESTABLISHED BY LIFTING THE FOOD OFF THE BRAKE PEDAL COMPLETELY AND RE-DEPRESSING THE BRAKE PEDAL. THE SEVERITY OF THE SUDDEN LOSS OF BRAKING (COMPLETE LOSS OF BRAKING) IS SHOCKING, ALARMING, AND PANIC ENDUCING AND RESULTS IN WHIPLASH TO THE VEHICLE OCCUPANTS AS THE PASSENGERS, BEING UNCONSCIOUSLY BRACED FOR DECELERATION, ARE SUDDENLY JOLTED BACK INTO THEIR SEATS. WHEN ANOTHER VEHICLE IS LOCATED IN FRONT OF THE VEHICLE THE SUDDEN LOSS OF BRAKING AND SUBSEQUENT WEAK BRAKING POWER DESPITE STRONG BRAKE PEDAL DEPRESSION IS HIGHLY ALARMING. THE MOST REPRODUCIBLE SITUATION IN WHICH THIS HAPPENS IS ON DRY PAVEMENT WHILE EXITING A HIGHWAY AND DECELERATING ON A STRAIGHT OR SLIGHTLY CURVED EXIT RAMP WITH ONE OR MORE POTHOLES. THE PHENOMENON OCCURS IN OTHER CIRCUMSTANCES AS WELL WHERE A POTHOLE IS ENCOUNTERED WHILE THE VEHICLE IS UNDER BRAKING.

I HAVE HAD THIS PROBLEM EVER SINCE I BOUGHT THIS CAR USED FROM A TOYOTA DEALERSHIP. IF I DRIVE OVER AN UNEVEN SURFACE, POTHOLE, ETC., MY CAR WILL SKIP AND THEN LURCH FORWARD. IT IS WORST ON WET ROADS. I HAVE TROUBLE STOPPING IT. ON SNOW I HAVE LITTLE TO NO TRACTION. I GOT A NEW SET OF TIRES AND I WASTED MY MONEY. NO DIFFERENCE. I DON'T FEEL SAFE DRIVING THIS VEHICLE. I HAVE BEEN DRIVING FOR YEARS, HAD MANY DIFFERENT VEHICLES, DRIVE AS PART OF MY JOB, AND HAVE NEVER EXPERIENCED ANYTHING LIKE IT. CONTACTING TOYOTA ABOUT IT WAS A WASTE OF TIME. I HAVE SPOKEN TO OTHER PRIUS 2010 OWNERS AND EVERY ONE SAYS THE SAME THING ABOUT HOW IT HANDLES WHEN GOING OVER BUMPS. THE SKIP AND LURCH COULD EASILY RESULT IN A REAR END COLLISION.

ALTHOUGH THE CAR WENT THROUGH THE RECALL FOR THE BREAK SYSTEM IS STILL HAVING THE SAME ISSUE EVER SINCE. THE OTHER ISSUE WITH THE BRAKES HAPPENS AFTER RAIN. IT MAKES A SCREECHING NOISE WITHOUT PERFORMANCE BEING EFFECTED. IT GOES AWAY USUALLY WITHIN A HALF AN HOUR. THIS HAS BEEN AN ONGOING THING TOO FOR FEW YEARS BY NOW. THE OTHER ISSUE I HAD AS WELL AS OTHERS IS DIMMING OF LIGHTS THAT HAS BEEN OCCURRING SINCE LAST YEAR. WE NEEDED TO SWITCH THE LIGHTBULBS MORE FREQUENTLY THAN SEEMS NORMAL. DIDN'T EVEN THINK IT WAS OUT OF THE ORDINARY UNTIL I READ THE COMMENTS HERE ABOUT IT. THE OTHER PROBLEM I STARTED TO HAVE IS WITH A STEREO DISPLAY SYSTEM AND THE VOICE ACTIVATION FOR THE BLUETOOTH. THE DISPLAY HAD SOME WEIRD LINES ON IT AFTER A VERY COLD OR A VERY HOT DAY (RADIO WAS WORKING FINE JUST THE DISPLAY WAS NOT WORKING PROPERLY). EVENTUALLY GOES BACK TO NORMAL BUT THIS STARTED HAPPENING THE LAST YEAR OR SO. THE SAME TIME ALSO HAD A PROBLEM WITH THE VOICE ACTIVATION UNIT WHICH TURNED ON UNEXPECTEDLY AND TURNED BACK ON IN 10 SECONDS AFTER EACH TIME I TURNED IT OFF. THIS WAS HAPPENING FOR A GOOD 30 MIN AT THAT TIME. THIS ONLY OCCURRED TWICE BUT BOTH TIMES WAS AFTER A HOT DAY LAST SUMMER. THIS YEAR SO FAR HAVEN'T HAPPENED YET.

THE FOLLOWING INFO IN QUOTES IS COPIED FROM THE OTHER COMPLAINT WHICH IS THE SAME ISSUE I HAVE - (OTHER COMPLAINT STATED) "WHEN YOU ARE AT LOWER SPEEDS AND HIT A POTHOLE OR BIG BUMP WHILE BREAKING, THERE'S A SUDDEN 'JOLT' AND IT FEELS AS IF THE BREAKS HAVE BEEN COMPLETELY RELEASED MOMENTARILY. IT ALMOST FEELS AS IF THE CAR LURCHES FORWARD. I FEEL IT HEIGHTENS THE CHANCE OF A CRASH DUE TO INCREASED DECELERATION TIME." IT SOMETIMES FEELS LIKE YOU ARE SLIDING ON ICE & HAVE NO CONTROL OVER THE CAR. (AND IT IS SCARY WHEN IT HAPPENS!) I HAD TOYOTA CHECK MY VEHICLE A FEW TIMES, BUT THEY WERE NOT ABLE TO DUPLICATE THE PROBLEM, SO NOTHING WAS FIXED. I THOUGHT IT WAS JUST MY CAR THIS WAS HAPPENING TO. NOW I FIND THAT I AM NOT ALONE IN THIS. THE COMPLAINT I REFERENCED STATED THAT THERE WAS AND A "PREVIOUS INVESTIGATION & PARTIAL RECALL BUT IT DIDN'T AFFECT ALL OF THE 2010 PRODUCTION VEHICLES, JUST A PORTION." I NEVER HEARD ABOUT ANY RECALL OR INVESTIGATION ON THIS. I AGREE WITH THE OTHER COMPLAINT THAT "THIS NEEDS TO BE RE-INVESTIGATED AS MY CAR AND COUNTLESS OTHER CARS (BOTH INVOLVED AND NOT INVOLVED IN THE LAST RECALL) ARE (STILL) MALFUNCTIONING WHEN IT COMES TO THE BREAKING SYSTEM AT SLOWER SPEEDS WHEN ON ROUGH ROADS / ENCOUNTERING POTHOLES / BUMPS."

IT WAS RAINING AND I WAS EXISTING THE I5 RAM, WHEN I BUMPED THE BRAKE, THE VEHICLE SPEEDED UP MORE, I CONTINUE TO PUMP THE BRAKE, THEN THE VEHICLE STARTED DRIFTING, THEN I TRIED CORRECTING, BUT IT DIDN'T WORK, THE VEHICLE KEPT ON DRIVING, FOR ABOUT 15 SECONDS COME TO STOP BY THE WALL OF THE I5, IT THEN BOUNCED VEHICLE BACKWARDS AND FINALLY THE VEHICLE COME TO STOP AFTER THE SHIFT BROKE, CAUSEING A TOTALLY CRASH, MEANING, NO MATTER HOW HARED I STEP ON THE BRAKE, IT DIDN'T STOP, IT FELT LIKE THERE WAS NO BRAKE SYSTEM. I ONLY BOUGHT THE CAR FOR 6 DAYS EARLIER, AND IT WAS MY THIRD TIME DRIVING IT. I HAVE BEEN A DRIVE FOR 7 YEARS AND I HAVE NEVER HAD ANY INCIDENT.

1 ORIGINAL RECALL DID NOTHING CONCERNING HITTING A POTHOLE AND LOSING BRAKES FOR 20 +- FEET..RESULT..ALWAY GIVE YOURSELF 20 EXTRA FEET AND PRAY. 2 ANTILOCK ON PACKED SNOW OR ICE RESULTS IN TOTAL LOST OF BRAKES..RESULT EITHER DRIVE INTO A SNOW BANK OR GO THROUGH THE RED LIGHT AND PRAY AGAIN. SO I GUESS TOYOTA ACCEPTS THE FACT THEY CHOOSE TO GIVE YOU STEERING CONTROL TO SAVE YOURSELF AND HOPE YOU ARE NOT AT A RAILROAD CROSSING! THERE IS NO PULSATING LIKE OTHER VEHICLES. 3 IF YOU ARE STOPPED ON ICE /SNOW...WITHOUT TRACTION CAR DOES NOT ROCK ..DOES NOT WANT TO MOVE... FOR STUDY CAN A METAL STUD TIRE BE MADE FOR PRIUSES???WOULD IT HELP OR SELL CAR ONLY IN FLORIDA..

WHILE DRIVING AROUND 70MPH I HAD TO HIT THE BRAKES HARD BUT SHORT. ABOUT 5 SECONDS LATER A BUNCH OF WARNING LIGHTS CAME ON AND THE VEHICLE BECAME VERY DIFFICULT TO STOP. PRETTY MUCH HAD TO STAND ON THE BRAKES TO SLOW DOWN AND THEN THE BRAKES WOULD LOCK UP SO I WOULD GET OFF THE BRAKES AND START THE SLOWING/STOPPING PROCESS OVER AGAIN. THIS IS THE SAME FAILURE MODE (ABS ACCUMULATOR NITROGEN GAS LEAKED INTO BRAKE HYDRAULIC FLUID WHEN ACCUMULATOR CRACKED) AS OTHER CARS (PRIUS AND LEXUS HYBRIDS) THAT TOYOTA DID RECALL BUT MY CAR IS OUTSIDE OF THE CURRENT RECALL SCOPE. IF THIS WAS NOT IN SOUTHERN CALIFORNIA'S DRY ROAD A MAJOR INCIDENT COULD HAVE TAKEN PLACE, ESPECIALLY WITH THE GRABBING/ LOCKING UP OF THE BRAKES.

THIS HAS HAPPENED SEVERAL TIMES OVER THE PAST TWO YEARS. AS I BRAKE AT LOW SPEEDS, THE CAR SURGES AHEAD AS THOUGH YOUR FOOT IS ON THE ACCELERATOR. SOMETIMES IT WAS SO SUBTLE, YOU WONDERED IF IT REALLY HAPPENED. TODAY (11/23/14) THERE WAS ABSOLUTELY NO MISTAKING IT. THE CAR SURGED FORWARD A COUPLE OF FEET AS I WAS SLOWING TO TURN LEFT. IF SOMEONE HAD BEEN STOPPED IN FRONT OF ME, I WOULD HAVE HIT THEM FROM BEHIND.

WHILE APPLYING THE BRAKES TO STOP AT AN INTERSECTION ONE OF THE FRONT TIRES WAS OVER A MANHOLE COVER AND THE CAR SKIDDED OVER IT LIKE I WAS BRAKING ON A PATCH OF ICE. AS SOON AS I WAS PAST THE COVER THE BRAKES ENGAGED AND STOPPED THE CAR. I NOTICED THIS OCCURRING EVERY TIME I WOULD BRAKE ON AN UNEVEN SURFACE WHERE THERE WAS SPACE BETWEEN ONE OF THE FRONT TIRES AND PAVEMENT. I HAD BOUGHT THE SAME MAKE, MODEL AND YEAR VEHICLE FOR MY SON 11 MONTHS LATER AND NOTICED THE SAME PROBLEM WHILE TEST DRIVING IT. WHEN I QUESTIONED THE SALESMAN ABOUT IT I WAS TOLD THAT IT WAS THE WAY THE ABS WORKS AND THAT IT WAS NORMAL. ON 11/20/2014 WHILE CHECKING THE AIRBAG RECALL LIST I NOTICED A RECALL FOR THE SAME PROBLEM THAT I WAS HAVING, RECALL ANNOUNCED 2/9/2010, NHTSA REF # 10V03900 SO I CALLED TOYOTA CUSTOMER SERVICE 1-800-331-4331 AND WAS TOLD THAT NEITHER CARS' VIN# SHOWED IN THE RECALL SO IT COULD NOT BE HAPPENING AND I WOULD NOT BE COVERED UNDER THE RECALL. THEY REFERRED ME TO A TOYOTA DEALER WHO TOLD ME THAT THE FIX WHICH WAS (REPROGRAMMING OF ABS CONTROL UNIT MODULE) WOULD NOT COVERED IN THE EXTENDED WARRANTIES OF EITHER CARS. I SHOULD NOT BE FINANCIALLY RESPONSIBLE FOR THE DIAGNOSTICS AND REPAIRS OF A KNOWN SAFETY PROBLEM WHICH HAD A RECALL. I UNDERSTAND THAT IT IS NOT THE DEALERS' FAULT AND THEY SHOULDN'T BE HELD FINANCIALLY RESPONSIBLE EITHER.

NHTSA CAMPAIGN NUMBER: 10V039000 COMPONENT(S): SERVICE BRAKES, AIR - THIS HAPPENS ALL THE TIME WHEN THE CONDITIONS ARE RIGHT. I COMPLAINED TO TOYOTA AT THE TIME THAT THIS CAR SHOULD HAVE BEEN IN THE RECALL LIST - IT DOES EXACTLY AS DESCRIBED IN THIS CAMPAIGN DESCRIPTION...THE BRAKES RELEASE WHEN BRAKING OVER BUMPS OR SLIPPERY SURFACES. THE FIRST TIME I TOOK IT IN, THEY SAID THEY COULD FIND NOTHING WRONG, AND THEY WERE 'WORKING AS DESIGNED'. I CALLED TOYOTA TODAY AFTER READING MORE ABOUT THIS RECALL, AND THEY TOLD ME I WOULD HAVE TO TAKE TO SERVICE AND GIVE THEM A RIDE TO SHOW THEM HOW IT HAPPENS. I DON'T UNDERSTAND WHY THIS CAR WASN'T INCLUDED IN THE RECALL. ANY SUGGESTIONS OR ASSISTANCE? ARE YOU STILL GETTING COMPLAINTS ABOUT THIS?

THIS IS A CHRONIC PROBLEM WITH THE CAR: WHEN IT HITS ROUGH TERRAIN, THE BRAKES DO NOT REACT PROPERLY. THERE IS A HESITATION BETWEEN THE TIME THE BRAKE PEDAL IS HIT AND THE TIME THE CAR SLOWS. (THERE WAS AN EARLIER REPAIR/RECALL FOR THIS ISSUE, AND THE INITIAL PROBLEM -- ALSO BRAKE-RELATED -- WAS HELPED; BUT THIS HESITATION PROBLEM -- ONLY ON GRAVEL OR ROUGH TERRAIN -- RESULTED.) IT WILL CAUSE AN ACCIDENT EVENTUALLY.

I CONTINUE TO HAVE A PROBLEM WITH BRAKING WHEN GOING OVER A BUMPY SURFACE. THIS HAS HAPPENED NUMEROUS TIMES. MOST RECENTLY, WHILE DRIVING OVER A BUMP IN THE ROAD, I APPLIED THE BRAKES AND THE CAR LUNGED FORWARD. LUCKILY, THERE WAS ENOUGH DISTANCE BETWEEN MY CAR AND THE CAR IN FRONT OF ME (WHICH HAD ALSO APPLIED THE BRAKES). I AM AFRAID THIS WILL CAUSE A SERIOUS ACCIDENT SOMEDAY. THIS HAS ALSO HAPPENED AT STOP SIGNS. I HAVE COMPLAINED TO THE DEALERSHIP A FEW TIMES AND THEY ACT AS IF THEY DON-++T KNOW WHAT I AM TALKING ABOUT, WHICH IS LUDICROUS. I EVEN MENTIONED THE ECU RECALL/FIX REGARDING THE BRAKING SYSTEM AND TOLD THEM THAT MY VEHICLE HAD THE FIX APPLIED AND THEY TOLD ME THAT THE FIX WAS NOT TO ADDRESS THE PROBLEM I AM DESCRIBING. THEY INSIST THAT NO ONE ELSE HAS COMPLAINED ABOUT IT. I TOLD THEM THAT I ASSUME THAT THEY HAVE BEEN DIRECTED TO TELL CUSTOMERS THAT THEY KNOW NOTHING ABOUT IT.

I WOULD LIKE TO FILE THIS CLAIM AS THE SAME INCIDENT DESCRIBED BELOW HAPPEN TWO TIMES IN LESS THAN TWO YEARS. THIS IS A BIG SAFETY ISSUE WHICH COULD HAVE BEEN FATAL. -- FIRST EVENT OCCURRED ON 8/17/2012 (ODOMETER 55899). BRAKE TOTALLY FAILED ON A FREEWAY AND ALMOST LOST MY LIFE THAT DAY. TOWED TO THE DEALER AND THEY REPLACED 1) BREAK CYLINDER ASSEMBLY PN#47050-47060, 2)GASKET, BREAK BOOST PN#44785-02060 & 3) BREAK FLUID. WHEN ASKED TO THE DEALER WHAT THE REASON FOR THE FAILURE WAS, WE WERE TOLD THAT THEY DO NOT KNOW THE CAUSE AND FAILED PART WAS SENT TO THE MANUFACTURER FOR INVESTIGATION. WE REQUESTED TO TELL US THE FINDINGS FROM THE MANUFACTURER BUT NEVER HEARD BACK AND SOON AFTER THIS INCIDENT TOYOTA HAD A RECALL FOR BREAKS. -- THE SECOND INCIDENT OCCURRED ON 7/16/2014 (ODOMETER 91965) AND SAME BRAKE FAILURE OCCURRED AGAIN AS DESCRIBED ABOVE.THIS TIME DEALER REPLACED 1) BREAK CYLINDER ASSEMBLY PN#47050-47140, 2) GASKET, BRAKE BOOST PN#44785-02060 & 3) BREAK FLUID. PLEASE NOTE THAT THE SECOND TIME THE BRAKE CYLINDER ASSEMBLY PN# IS DIFFERENT. WE ASKED THE DEALER AGAIN WHAT WAS THE REASON FOR FAILURE OF THE SAME PART AGAIN BUT DID NOT GET A CLEAR ANSWER FROM THEM. WE WROTE SEVERAL EMAILS TO THE DEALER BUT NO RESPONSE YET AS OF TODAY (8/19/14). I AM A VERY UNHAPPY CUSTOMER. WHAT WILL TOYOTA DO IF THIS HAPPENS AGAIN? SOON OUR WARRANTY WILL EXPIRE AND IF THIS HAPPENS AGAIN WHICH IS A TOYOTA'S EXISTING PROBLEM, HOW IT WILL BE COVERED? -- HOPE TO HEAR SOON FROM TOYOTA.

REPAIR HAS DONE NOTHING TO CORRECT THE PROBLEM. THE SAME PROBLEM HAS OCCURED INTERMITTENTLY BEFORE AND AFTER THE "FIX".

I BROUGHT MY 2010 PRIUS INTO THE TOYOTA MARIN (CALIFORNIA) DEALER IN JANUARY 2014 IN RESPONSE TO THEIR RECALL RELATED TO PROBLEMS WITH STEPPING ON THE BRAKE AND HAVING THE PRIUS ACCELERATE RATHER THAN STOP. THE CORRECTIVE SOFTWARE WAS PRESUMABLY INSTALLED. FAST FORWARD TO FATHER'S DAY, JUNE 15, 2014. I AM PARKING MY PRIUS FOR A FATHER'S DAY BRUNCH. I'M GOING ABOUT TWO MILES PER HOUR INTO A PARKING SPACE. I PUT MY FOOT ON THE BRAKE. THE CAR ACCELERATES. I MENTALLY DOUBLE CHECK THAT I HAVE MY FOOT ON THE BRAKE. I DO. OUT OF CONTROL, THE CAR JUMPS THE CURB AND SMASHES RIGHT INTO A TREE. MY WIFE ASKS IF MY FOOT IS ON THE BRAKE. I TRIPLE CHECK. IT STILL IS--I HAVEN'T MOVED IT. A WEEK LATER I FEEL THE TRAUMA OF CONSTANTLY VISUALIZING THE POSSIBILITY OF HAVING TRIED TO STOP AT A CROSS WALK AND KILLING A FAMILY ON THE WAY TO THEIR FATHER'S DAY BRUNCH. --IT TOOK THREE DAYS OF CONSTANT CALLING AND DYSFUNCTIONAL EXTENSIONS TO CONNECT WITH A PRIUS CASE MANAGER. THEN SHE INFORMED ME IT WOULD TAKE ME MORE THAN A MONTH TO HAVE MY CAR INSPECTED AND GET AN ASSESSMENT. IF I RENTED A CAR THERE WOULD BE NO ASSURANCE IT WOULD BE COVERED. --THIS PROBLEM HAPPENED AFTER I RESPONDED TO THE RECALL. HOW CAN I TRUST A CAR THAT IS AUTOMATICALLY CRASHING AFTER THAT PRECISE PROBLEM HAS ALLEGEDLY BEEN ADDRESSED? --I JUST RECEIVED (JULY 19, 2014) A LETTER FROM TOYOTA SALES SAYING THE CAR'S BRAKES AND ACCELERATOR WERE TESTED AND "ALL IS FINE." HOWEVER, IN MY AND OTHERS' SIMILAR EXPERIENCES THE SURGE HAPPENS ONLY OCCASIONALLY. WE BOUGHT THE CAR USED, HAVE GONE ABOUT 20,000 MILES WITH IT, AND NEVER HAD THE PROBLEM. SO A TEST EVEN FOR A YEAR AT A TIME IS IRRELEVANT. --MY "ASK": SINCE OTHERS SHARE THIS EXPERIENCE AND IT COULD RESULT IN DEATH, I WANT TOYOTA TO SELL THIS CAR FOR PARTS AND RECALL THE 2010 PRIUS UNTIL A SOLUTION CAN BE FOUND. I AM SHOCKED AT PRIUS' IRRESPONSIBILITY.

BACK IN 2010, WE NOTICED THAT, WHEN BRAKING, THE CAR WOULD LURCH FORWARD. THIS HAPPENED SEVERAL TIMES AT RANDOM. AT THAT TIME, WE TOOK THE CAR IN TO FIX THE PROBLEM. VICTORY TOYOTA IN CANTON, MICHIGAN, TOLD US THAT THERE WAS NOTHING WRONG; THEIR DIAGNOSIS AND COMPUTERS SHOWED THAT NO ERRORS HAD OCCURRED. WE DROVE IT FOR A SHORT TIME, AND IT CONTINUED TO HAVE THE ISSUE. WE TOOK IT BACK IN TO THE DEALERSHIP, THEY AGAIN SAID THAT THERE WAS NOTHING WRONG. THEY SAID THAT THEY TOOK IT FOR A TEST DRIVE, AND NOTHING HAPPENED. WE WERE MADE TO THINK THAT THE ISSUE WAS IN OUR HEADS, SO WE TOOK THE CAR BACK AND TRIED TO DEAL WITH THE ISSUE, EVEN THOUGH IT CONTINUED OVER THE YEARS. FINALLY, THIS YEAR, WE NEARLY GOT INTO TWO SEPARATE ACCIDENTS AS A DIRECT RESULT OF THIS SUDDEN LURCHING FORWARD. I TOOK THE CAR BACK INTO THE SERVICE DEPARTMENT OF VICTORY TOYOTA, AND WAS TOLD BLUNTLY THAT THERE WAS NEVER A RECALL FOR THIS ISSUE, THAT, UNLESS I COULD RECREATE THE PROBLEM WITH A TECHNICIAN IN THE CAR, I WAS MAKING THINGS UP. THAT IS WHAT LEAD TO THIS COMPLAINT. I DID SOME RESEARCH AND FOUND THAT THE CAR HAD INDEED BEEN RECALLED FOR THIS BRAKE ISSUE WITH RECALL ID # 68066. SO THEY LIED ABOUT THE RECALL HISTORY FOR MY CAR. ALSO, RECREATING SOMETHING THAT HAPPENS AT RANDOM DURING A FINITE TIME PERIOD, SUCH AS A TEST DRIVE, IS IMPROBABLE, AND TO MAKE SERVICING THE CAR CONTINGENT ON THAT TEST DRIVE IS LUDICROUS.

EVER SINCE ACQUIRING THIS VEHICLE EARLIER THIS YEAR, I HAVE BEEN EXPERIENCING LOSS OF BREAKING FOR A SECOND EVERY TIME I HIT A POTHOLE AND BUMPY SPOT. IT HAPPENS EVERY OTHER TIME. UPON GOGGLING THIS PROBLEM, I LEARNED THAT THE PROBLEM WAS FIRST REPORTED TO NHTSA WAY BACK IN 2009. BUT I DO NOT SEE ANY RECALLS RELATED TO THIS PROBLEM. YOUR WEBSITE SAYS YOU HAVE RECEIVED ABOUT 33 COMPLAINS. UNLESS I MISSED SOMETHING, IS THERE ANY STATUS REPORT FROM TOYOTA OR THE RECALL THAT SPECIFICALLY ADDRESSES THIS PROBLEM? ALSO, I LIVE IN THE EAST COAST, SPECIFICALLY IN NJ. WE HAD A BRUTAL WINTER THIS YEAR. IN ONE INCIDENT, I WAS DRIVING UP A SLIGHTLY ELEVATED ROAD (BARELY 2--5% INCLINE) IN A 25MPH RESIDENTIAL ROAD WITH SLIGHTLY SLIPPERY ROAD (NOT REALLY BLACK ICE PER SE). I LOSS CONTROL AND TRACTION CONTROL LITE UP AND STARTED BEEPING. WHILE TRYING TO BRING THE CAR IN CONTROL, MY CAR ENDED UP ON THE OTHER SIDE (THANKFULLY THERE WERE NO VEHICLES PARKED ON THE OTHER SIDE OR ANY ONCOMING VEHICLES) AND THEN SHIFTED TO THE RIGHT BUT FINALLY MANAGED TO BRING IT BACK IN CONTROL. OTHER MISC INFORMATION: I LEARNED ABOUT A RECALL EARLIER THIS YEAR RELATED TO ECU BOARD PROGRAMMING UPDATE FROM THE NEWS MEDIA (SINCE I WAS A NEW OWNER, TOYOTA PROBABLY DIDN'T HAVE MY INFORMATION SO NEVER GOT RECALL NOTICE) AND I WENT TO THE DEALER FOR UPDATE. I WAS HOPING SOFTWARE UPDATE MIGHT ALSO ADDRESS POTHOLE/LOSS OF BREAK PROBLEM BUT IT HAS NOT HELPED.

THIS HAS OCCURRED ON MULTIPLE INCIDENTS. THIS CAR DOES NOT STOP PROPERLY ON ROUGH ROADS. WHEN HITTING A POTHOLE, BUMP, MANHOLE COVER, ROUGH ROAD WHILE APPLYING THE BRAKES, INSTEAD OF STOPPING, THE CAR SURGES FORWARDS APPROXIMATELY 5-10 FEET AS THOUGH THERE WERE NO BRAKES. EVENTUALLY, THE BRAKES WORK AND THE CAR STOPS. BUT IT CAN BE REALLY SCARY. I HAVE TAKEN IT TO TOYOTA SEVERAL TIMES, BUT THEY CANNOT "REPLICATE THE INCIDENT." BASICALLY, I THINK THEY DRIVE IT AROUND THE BLOCK AND IT DOESN'T HAPPEN. IT IS ALWAYS WORSE WITH THE SUMMER TIRES VS THE STUDDED WINTER TIRES. THEY SAY IT HAS TO DO WITH THE REGEN BRAKES SWITCHING TO THE ANTI-LOCKS, BUT I REGULARLY DRIVE RENTAL CARS WITH ANTI-LOCKS FOR WORK IN OTHER CITIES, AND I KNOW WHAT ANTI-LOCKS FEEL LIKE. I HAVE NEVER FELT THE "CHATTER" ONE FEELS WHEN THE ANTI-LOCKS KICK ON. I DO NOT BELIEVE THE ANTI-LOCKS WORK PROPERLY ON THIS CAR. ON MAY 3, 2012, I HAD TO REPLACE THE RIGHT REAR BRAKE (ROTOR, PLATE, PADS) DUE TO UNEXPECTED CORROSION. MY CAR HAD ~17-18,000 MILES ON IT AND WAS ONLY 1.5 YEARS OLD!

WHEN BRAKES RESUME POWER, THE INCREASED FORCE RESULTS IN A SUDDEN DROP IN SPEED. THIS INCIDENT INCREASES THE RISK OF A REAR END COLLISION EITHER TO A VEHICLE IN FRONT OR FROM A VEHICLE BEHIND THE PRIUS.

WHEN APPLYING LIGHT TO MODERATE BRAKING IN PREPARATION TO MAKE A RIGHT TURN, I WENT OVER SOME BUMPY PAVEMENT AND THE CAR SEEMED TO LURCH FORWARD. IT WAS PROBABLY A LOSS OF BRAKING RATHER THAN ACTUAL ACCELERATION, BUT IT WAS VERY DISCONCERTING AND I'M LUCKY IT DIDN'T CAUSE AN ACCIDENT. I NOW HAVE OVER 49,000 MILES ON THE CAR AND THIS HAS HAPPENED ON QUITE A FEW OCCASIONS. I KNOW THERE WAS A RECALL ON SOME 2010 PRIUS VEHICLES FOR THIS PROBLEM BUT MY CAR WAS NOT RECALLED. MY DEALER SAYS THERE IS NO "SOFTWARE FIX" FOR THIS PROBLEM. I FIND IT UNACCEPTABLE THAT TOYOTA DOESN'T HAVE A SOLUTION FOR THIS AS IT IS A REAL SAFETY ISSUE. IT'S JUST PURE LUCK THAT I HAVEN'T BEEN INVOLVED IN AN ACCIDENT WITH POSSIBLE INJURIES OR WORSE. I INTEND TO PURSUE THIS AGAIN WHEN I BRING THE CAR IN FOR THE 50,000 MILE SERVICE AND INVERTER RECALL, BUT I'M NOT VERY HOPEFUL. MAYBE IF MORE OWNERS LODGE A COMPLAINT ON THIS SITE, TOYOTA WILL BE FORCED TO CORRECT THIS ISSUE.

AS I WAS APPROACHING A RED LIGHT I APPLIED THE BRAKES AND THEN SHORTLY AFTER HIT A POT HOLE AND THE CAR LUNGED FORWARD AS IF ACCELERATING ON IT'S OWN. FORTUNATELY THERE WASN'T ANOTHER VEHICLE IN FRONT OF ME AS I WOULD HAVE MOST DEFINITELY REAR-ENDED IT. I ALMOST SHOT INTO THE INTERSECTION AND MOST CERTAINLY SHOT PAST THE NORMAL STOPPING SPOT FOR WAITING AT A RED LIGHT. SCARY INCIDENT TO SAY THE LEAST.

BRAKES ON VEHICLE OCCASIONALLY MOMENTARILY DISENGAGES WHEN I HIT A BUMP, PARTICULARLY ON A SLIPPER SURFACE, WHILE BRAKING AT LOW OR MODERATE BRAKING. THIS HAS HAPPENED MULTIPLE TIMES. IT IS VERY OBVIOUS WHEN THIS HAPPENS. RECENTLY IT HAPPENED WITH MY WIFE IN THE CAR, I WAS BRAKING MODERATELY, THE BRAKES FULLY DISENGAGED FOR ABOUT A SECOND, WHEN THEY DID I INCREASED PRESSURE ON THE BRAKE PEDAL AND THE CAR SEVERELY LURCHED WHEN THE BRAKES RE-ENGAGED. THE 2010 PRIUS HAD A RECALL FOR THIS, BUT MINE IS LATE IN THE MODEL YEAR AND WAS NOT SUBJECT TO THAT RECALL. TOYOTA USA AND THE DEALER, OF COURSE, SAYS THERE IS NOT A PROBLEM AND THAT THEY CANNOT DO ANYTHING ABOUT IT.

PLEASE LET ME STATE THAT I AM EXTREMELY HAPPY WITH THE DEALERSHIP THAT I BOUGHT THE CAR FROM. ALL SERVICES FROM OIL CHANGES TO REPAIRS HAVE DONE BY THIS DEALER ONLY. BUT EVER SINCE I PURCHASED THIS VEHICLE, I HAVE BEEN CONSTANTLY COMPLAINING ABOUT A STRANGE BRAKING ISSUE. WHEN I AM TRAVELING 25 MPH OR ABOVE AND HIT ANY KIND OF IMPERFECTION IN THE ROAD ( IE. RAILROAD TRACK, DIP, POTHOLE, MANHOLE COVER ETC.) MY BRAKES DISENGAGE FOR A SPLIT SECOND. I WILL STILL HAVE MY FOOT ON THE BRAKE AND GO OVER IMPERFECTION AND FOR A BRIEF SECOND THE CAR SURGES FORWARD RAPIDLY AND THEN THE BRAKE ENGAGES AGAIN. I HAVE COMPLAINED ABOUT THIS MORE THAN 3 TIMES. ALL THREE TIMES THE DEALER SAYS THAT THEY CAN NOT REPEAT THIS ISSUE. I NOW HAVE 70,000 MILES ON THE CAR AND THIS IS STILL HAPPENING. ALTHOUGH I AM THE PRIMARY USER OF THIS VEHICLE, MY WIFE REFUSES TO DRIVE THE CAR CALLING IT UNSAFE. TODAY 3.25.2014 I HAVE DROPPED OFF THE CAR AT THE DEALER FOR A RECALL AND I HAVE MENTIONED THE PROBLEM AGAIN, MY SERVICE ADVISER IS NOW TELLING ME THAT THIS RECALL (SOFTWARE UPDATE FOR MOTOR GENERATOR ECU AND POWER MANAGEMENT ECU) SHOULD TAKE CARE OF THE PROBLEM.)

WHEN MY HUSBAND WAS DRIVING OUT OF THE PARKING LOT IN CHARLOTTE ON FRIDAY 02/07, ALL 3 LIGHTS - BRAKE, ABS, SKID CONTROL LIGHTS ALL WENT UP. WHEN HE STEPPED ON THE BRAKE, HE DIDN'T FEEL ANYTHING. LUCKILY HE WAS JUST GETTING OUT OF THE PARKING LOT, SO HE WAS DRIVING SLOWLY. WHEN HE STEPPED ALL THE WAY DOWN ON THE BRAKE, IT HAD THIS LOUD METAL RATTLING NOISE, AND HE WAS ABLE TO STOP. WE TOWED THE CAR TO TOWN AND COUNTRY TOYOTA ON SATURDAY, THE ASSISTANT SERVICE MANAGER SAID HE'S NEVER SEEN IT BEFORE, AND THE ERROR CODE SHOWN DURING DIAGNOSIS IS A CODE THEY'VE NEVER SEEN. THE MESSAGE ASKED THEM TO CONTACT TOYOTA TECHNICAL SERVICE. ON MONDAY 02/10, THE DEALER CALLED AND TOLD US THAT IT WILL COST OVER $4500 TO FIX IT. WE BOUGHT THE CAR IN FEB 2011 AS BRAND NEW CAR, SO IT'S JUST 3 YEARS OLD. I THEN CONTACTED TOYOTA CUSTOMER SERVICE, AND REQUESTED THAT TOYOTA COVERS THE REPAIR. I WAS TOLD THAT THERE IS NO RECALL PROGRAM RELATED TO THIS PROBLEM, AND THAT IF I RUN INTO THE SAME SITUATION AGAIN, OR OTHER PEOPLE RUN INTO THE SAME ISSUE, THEN TOYOTA MIGHT CONSIDER A RECALL, AND WOULD REFUND ME FOR THE REPAIR. THIS IS A VERY DANGEROUS SITUATION THAT I HOPE I'LL NEVER RUN INTO IT AGAIN EVER! IT JUST SEEMS TOYOTA IS VERY COLD AND INDIFFERENT TO PEOPLE'S SAFETY.

THE ABS/BRAKE/STABILITY LIGHTS ARE "ON" PRIUS DASH. THE BRAKE LOST PRESSURE AND MUSHY. THE BRAKE MUST BE PUMPED A FEW TIMES TO GET PRESSURE AND TO STOP THE CAR. EITHER THIS IS ABS ACCUMULATOR(JUST FOUND OUT THERE IS A RECALL WHILE GETTING DEALER APPOINTMENT) FAILURE OR BRAKE MASTER CYLINDER FAILURE. THERE IS NO FLUID LEAK VISIBLE OUTSIDE OR INDICATOR LIGHT BUT THE FLUID IS ALMOST EMPTY IN THE RESERVOIR. I DON'T HAVE DEALER DIAGNOSIS AT THIS POINT YET. I'M NOT SURE IF THE ACCIDENT I HAVE ON 1/27/2014 THAT I'VE REAR-ENDED ANOTHER VEHICLE WHILE TRAVELING ABOUT 30-35MPH AND TRIED TO STOP BUT THE CAR DID NOT STOP AND BUMPED INTO THE CAR IN FRONT. FORTUNATELY, THERE IS INJURY OR MAJOR DAMAGES. AT THAT TIME I DIDN'T THINK OF IT THAT THE BRAKE MAY HAVE ISSUE OR NOT BUT THINKING BACK THE BRAKE DIDN'T HAVE ENOUGH BITE TO STOP EVEN THOUGH THE CAR IS TRAVELING SLOW ENOUGH AND THERE IS AMPLE DISTANCE.

ON OCTOBER 10TH, 2013 AT 7 PM, I NOTICED SEVERAL BRAKE LIGHTS, ABS, AND SLIDING SIGN LIGHT CAME ON WHEN I STARTED MY CAR. I THOUGHT IT WAS SOME KIND OF ELECTRICAL GLITCH SO I TURNED MY CAR OFF AND TURNED IT BACK ON. THE LIGHTS STAYED SAME. MY HUSBAND WHO SAT ON THE PASSENGER SIDE LOOKED INTO THE MANUAL BOOK AND TOLD ME THOSE LIGHTS WERE INDICATED FOR BRAKE SYSTEM. WE DECIDED TO GO HOME TO FIGURE OUT WHAT WE NEEDED TO DO. AS SOON AS I STARTED TO DRIVE, I NOTICED BRAKE PEDAL WAS MUCH LOWER THAN IT USUALLY IS AND ALSO NOTICED BRAKE WAS NOT WORKING. MY CAR KEPT MOVING EVEN WHEN I PRESSED THE BRAKE ALL THE WAY. AT THAT MOMENT, I KNEW I HAD TO TAKE MY CAR TO DEALER RIGHT AWAY. THERE WERE NO WARNING SIGNS OR NOISE FOR A DRIVER TO NOTICE BEFORE THE WHOLE BRAKE SYSTEM WAS COMPLETELY FAIL TO PERFORM. IN JANUARY 2013, TOYOTA RECALLED MANY PRIUS IN SAME MODEL AND SAME YR AS MINE FOR TOTAL BREAK SYSTEM FAILURE. EVEN THOUGH MY VIN NUMBER WAS NOT UNDER THEIR RECALL LIST, MY CAR'S BRAKE SYSTEM BROKE DOWN COMPLETELY TO FUNCTION DUE TO SAME REASONS TOYOTA RECALLED MANY PRIUS 2010 THIS YEAR. TOYOTA REFUSED TO FIX MY CAR UNDER THEIR RECALL SYSTEM WARRANTY BECAUSE MY VIN NUMBER IS NOT UNDER THEIR RECALL LIST. TOYOTA DEALER CHARGED ME $4300 TO REPLACE THE WHOLE BRAKE SYSTEM FOR MY CAR AND IT TOOK 4 WEEKS TO FIND THE PARTS IN NORTH AMERICA TO FIX MY CAR. IT COST ME ANOTHER $1000 TO RENT A CAR WHILE MY PRIUS AT TOYOTA DEALER TO FIND THE PARTS TO FIX IT. I WAS FORTUNATE ENOUGH THAT MY BRAKE SYSTEM DIDN'T BLOW OUT ON ME WHEN I WAS DRIVING 75MPH ON FREEWAY. I'M SURE THERE ARE MANY OTHER PRIUS 2010 HAVE BRAKE SYSTEM FAILURE LIKE MINE EVEN THOUGH THEY WERE NOT UNDER THEIR RECALL LIST.

I BELIEVE THE NHTSA SHOULD INVESTIGATE WHETHER TOYOTA HAS UNDERSTATED THE NUMBER OF 2010 PRIUS CARS WITH POTENTIALLY FAULTY BRAKE ACCUMULATOR PUMPS. THE COMPANY RECALLED THOUSANDS OF THE CARS MANUFACTURED BETWEEN JUNE AND OCTOBER, 2009. MY DEALER RECENTLY TOLD ME THAT MY 2010 PRIUS, MANUFACTURED IN DECEMBER, 2009 ? JUST TWO MONTHS LATER ? HAS ESSENTIALLY THE SAME PROBLEM. THEY INFORMED ME THAT THIS IS A ?SAFETY CONCERN? AND THAT THE PUMP SHOULD BE REPLACED ?AS SOON AS POSSIBLE,? AT A COST OF OVER $4,000. BUT BECAUSE MY CAR WAS MANUFACTURED TWO MONTHS AFTER THE LAST CARS COVERED IN THE RECALL, THEY HAVE REFUSED TO PAY FOR THE REPLACEMENT. I AM VERY DOUBTFUL OF THE IDEA THAT PROBLEM AFFECTING MY CAR IS DIFFERENT FROM THE DEFECT RESULTING IN THE RECALL. FIRST, THE KEY ISSUE IS ESSENTIALLY IDENTICAL: CONTAMINATED FLUID THAT COULD RESULT IN A LOSS OF BRAKING POWER. SECOND, THE CAR IS THE SAME MODEL AND YEAR AS THOSE RECALLED, JUST MANUFACTURED A COUPLE OF MONTHS LATER. THIRD, THIS SORT OF REPAIR ? THE NEED TO REPLACE A SINGLE, VERY EXPENSIVE COMPONENT LESS THAN FOUR YEARS AFTER PURCHASE ? OUGHT TO BE RARE. IF IT?S NOT, THIS SUGGESTS A SYSTEMATIC DIFFICULTY.

UPON BRAKING OVER A BUMP, POTHOLE, WET LEAVES AND/OR ANY COMBINATION OF THE AFOREMENTIONED CIRCUMSTANCES, THE PRIUS ACCELERATES FORWARD, THUS CREATING A VERY UNSAFE DRIVING CONDITION. SINCE I ORIGINALLY PURCHASED THE VEHICLE, IT HAS DONE THIS ON NUMEROUS OCCASIONS. I DO NOT FEEL SAFE DRIVING THIS VEHICLE AND AM AFRAID THAT THIS BRAKING ISSUE MAY RESULT IN AN ACCIDENT THAT OTHERWISE WOULD HAVE BEEN A NON-ISSUE FOR ANY OTHER VEHICLE. IN MY 19+ YEARS OF DRIVING, I HAVE NEVER HAD A VEHICLE DO THIS WHILE BRAKING. I, THEREFORE, IMPLORE THE NTSB TO DUTIFULLY CARRY OUT ITS MISSION STATEMENT OF PROTECTING MOTORISTS BY FORCING TOYOTA TO RECALL SAID VEHICLE IN ORDER TO PROPERLY REMEDY THIS ISSUE BEFORE PREVENTABLE ACCIDENTS OCCUR AND LIVES ARE POTENTIALLY LOST.

THE ABS SYSTEM ON MY 2010 PRIUS SEEMS TO RELEASE THE BRAKE WHEN APPLIED ON ROUGH SURFACES GOING DOWNHILL WHICH GIVES A SENSE OF ACCELERATION AND LACK OF VEHICLE CONTROL.

COMING TO A STOP LIGHT, I APPLIED THE BRAKES. THIS HAS BEEN AN ONGOING ISSUE WITH MY CAR THAT WHEN APPLYING THE BRAKES AND A BUMP IN THE ROAD IS DETECTED, THE CAR SUPPOSEDLY SWITCHES TO ABS BRAKING. THE NET EFFECT OF IT IS THAT THE BRAKES TEMPORARILY DISENGAGE CAUSING THE CAR TO ACCELERATE FOR A BRIEF PERIOD UNTIL YOU REAPPLY THE BRAKES AND EVENTUALLY COME TO A STOP. SO AS A RESULT, THE FROM THE MOMENT YOU APPLY THE BRAKES TO THE TIME YOU STOP, THERE IS A "LURCHING FORWARD" OF ABOUT 5 FEET UNDER WHICH YOU HAVE NO CONTROL OVER THE CAR. THAT IS QUITE SCARY SINCE IF PER CHANCE A PERSON WERE CROSSING THE ROAD WHILE YOUR CAR HIT A BUMP IN THE ROAD, YOUR VEHICLE COULD THEORETICALLY HIT THE PERSON BEFORE THE BRAKES HAD A CHANCE TO KICK IN. I'VE CHECKED THE BLOGS AND HAVE NOTICED THAT PEOPLE WITH PRIUSES FROM VARIOUS YEARS HAVE REPORTED THE SAME PROBLEM. I NOTICED THIS PROBLEM EARLY ON IN MY OWNERSHIP OF THE CAR, AND ACTUALLY ASKED THE DEALER TO FIX THE PROBLEM. THEY REPORTED TO ME THAT EVERYTHING WAS WORKING PROPERLY. I THEN ASKED THEM TO TEST DRIVE IT FOR A WHILE TO REPRODUCE THE PROBLEM. THEY HAD MY CAR FOR A WEEK AND SUPPOSEDLY WERE UNABLE TO REPRODUCE THE PROBLEM.

THIS VEHICLE SHOULD BE PART OF THE LARGER TOYOTA RECALL ON BRAKES THAT WAS ANNOUNCED EARLIER THIS YEAR. AFTER A FEW THOUSAND MILES, I NOTICED THAT THE BRAKES GAVE WAY IF THE PRIUS HITS A BUMP OR POTHOLE. TOYOTA'S STATEMENT THAT "CUSTOMERS ARE PERCEIVING INCONSISTENT BRAKE FEEL DURING SLOW AND STEADY APPLICATION OF THE BRAKES ON ROUGH OR SLICK ROAD SURFACES" IS AN UNDERSTATEMENT. THE BRAKES DON'T ACTUALLY WORK WHEN YOU ARE DECELERATING AND HIT A BUMP, WHICH IS PROBLEMATIC WHEN YOU LIVE IN A CITY NOTORIOUS FOR POTHOLES. I REPORTED THIS ISSUE EARLY ON TO MY DEALER, AND HAVE SINCE FOLLOWED UP, EACH TIME BEING MET WITH THE SAME RESPONSE: THERE ARE NO REPORTS ON THIS ISSUE. FOR WHATEVER REASON, TOYOTA FEELS THAT ONLY CERTAIN VIN LOT NUMBERS MERIT THE RECALL, BUT I CAN ASSURE THEM THE PROBLEM IS MORE WIDESPREAD. MOST OWNERS I'VE TALKED TO HAVE TRIED TO ACCOMMODATE THE PROBLEM BY BEING AWARE OF BUMPS WHEN COMING TO A STOP, BUT AT SOME POINT SOMEONE WILL INJURE OR KILL SOMEONE ELSE AS A RESULT OF THIS BRAKING ISSUE.

THIS INCIDENT HAS OCCURRED NUMEROUS TIMES SINCE PURCHASING THE CAR, BUT IT WASN'T UNTIL LAST WEEK (9/6/2013) THAT I BECAME TERRIFIED AS I ALMOST HIT ANOTHER VEHICLE IN FRONT OF ME. WHENEVER MY PRIUS RUNS OVER A POTHOLE, BUMP, UNEVEN SURFACE, OR DEEP MANHOLE COVER AS I AM BRAKING TOWARDS AN INTERSECTION TO COME TO A STOP (FOR ME, ALL THESE INCIDENTS OCCURRED WHEN I APPROACHED AN INTERSECTION) THE BRAKES STOP WORKING FOR A BRIEF MOMENT AND SUDDENLY MY CAR JERKS FORWARD, LURCHES FORWARD, OR ACCELERATES. I HAVE TO PRESS DOWN MY BRAKES REALLY HARD TO THE FLOOR TO STOP THE VEHICLE WHEN THIS HAPPENS. WHEN THIS FAILS, I IMMEDIATELY RELEASE THE BRAKE AND RE-APPLY VERY HARD TO THE FLOOR TO STOP THE CAR. IN THESE MOMENTS IT BECOMES SCARY AS I AM NEVER SURE IF THE CAR WILL COME TO A STOP BEFORE THE INTERSECTION. LAST WEEK, I WAS APPROACHING A BUSY INTERSECTION WHILE BRAKING AND I RAN OVER A UNEVEN POTHOLE COVER/FILLER AT ABOUT 5 TO 15 MPH WHICH CAUSED MY CAR TO ACCELERATE TO LIKE 20 OR 25 MPH! I HAD TO BRAKE VERY HARD IN ORDER TO STOP MY CAR AND SWERVE TO THE RIGHT TO AVOID HITTING THE CAR IN FRONT OF ME. THIS PROBLEM ONLY OCCURS WHEN MY RIGHT SIDE TIRES HIT THE UNEVEN SURFACE, MANHOLE COVER, POTHOLES, BUMPS, ETC. I HAVE NOT HAD AN INCIDENT WHERE IT HAPPENED WITH THE LEFT TIRES.

THIS INCIDENT HAS OCCURRED TWICE UNDER IDENTICAL CONDITIONS, IN THE SAME LOCATION. THE CAR DID NOT ENGAGE THE BRAKES UNTIL APPROXIMATELY ONE SECOND AFTER I DEPRESSED THE PEDAL.

BOTH TIMES I WAS DRIVING ON A SLIGHT DOWNHILL AT ~20 MPH. IMMEDIATELY AFTER I PASSED OVER SOME BUMPS, I DEPRESSED THE BRAKES, AND THERE WAS A SIGNIFICANT DELAY IN THE BRAKES BEING ENGAGED (1S).

WHILE BRAKING AT LOW SPEEDS -- SUCH AS WHILE APPROACHING A TRAFFIC LIGHT OR AN INTERSECTION -- PASSING OVER A POTHOLE OR UNEVEN ROAD SURFACE OFTEN CAUSES THE BRAKES TO DISENGAGE. THE SENSATION IS ONE IN WHICH MY FOOT IS IN THE SAME PLACE AS IT WAS WHEN I BEGAN BRAKING, BUT SUDDENLY THERE IS NO GIVE TO THE PEDAL, THE BRAKING HAS STOPPED -- BRAKING DOES NOT RETURN UNTIL I PUSH FURTHER DOWN ON THE PEDAL. MY FOOT IS NOT DISLODGED BY THE BUMP, AND THE BRAKING MECHANISM WILL NOT RE-ENGAGE UNLESS I PUSH THE PEDAL TO A NEW, DEEPER LOCATION. IT IS OBVIOUSLY DISCONCERTING AT INTERSECTIONS, AND SINCE MOVING TO A NEW LOCATION AND HAVING TO RE-LEARN WHERE ON MY ROUTES THIS PROBLEM WILL OCCUR, I DECIDED IT WAS TIME TO FILE A COMPLAINT. THE FRUSTRATION IS THAT THIS ISSUE WAS SUPPOSEDLY SOLVED A COUPLE YEARS AGO WITH A SOFTWARE FIX FROM TOYOTA, BUT THAT FIX SEEMS TO NOT HAVE WORKED. I FILED A COMPLAINT ABOUT THE PRIUS PROBLEM WITH SOME AGENCY (POSSIBLY NHTSA OR FTC) A FEW YEARS AGO WHEN THE OTHER, MORE NOTABLE, BRAKE-STICKING PROBLEM IN OTHER TOYOTAS WAS IN THE NEWS.

WHEN I TRY TO BRAKE, OCCASIONALLY, THE CAR JUMPS FORWARD, INSTEAD OF STOPPING. IT MOVES LIKE 6 INCHES TO 12 INCHES. IT HAPPENS MORE OFTEN WHEN I TRY TO BRAKE AT A STOP SIGN, WHEN THE ROAD IS ROUGH, OR THERE IS A POTHOLE. IT GIVES A FEELING OF THAT CAR ACTUALLY ACCELERATED INSTEAD OF SLOWING, AND FEELS UNSAFE.

THIS HAS HAPPENED ATLEAST 4 TIMES IN THE LAST YEAR, WHERE THE CAR HAS LOST COMPLETE BRAKING POWER AND AT THE TIME THIS HAPPENS, ALL THE LIGHTS ON THE DASHBOARD LIGHT UP FOR A FEW SECONDS AND ON SUBSEQUENT PUMPING OF THE BRAKE PEDAL, THE BRAKE POWER RETURNS TO NORMAL. ON ONE OCCASION I ALMOST ENDED UP IN THE MIDDLE OF AN INTERSECTION, THANKFULLY THERE WAS NO ONCOMING TRAFFIC AND WAS ABLE TO RECOVER WITHOUT GETTING CRASHED INTO. I SEE A LOT OF SIMILAR COMPLAINTS HERE AND ON TOYOTA'S OWN COMMUNITY PORTAL DESCRIBING THE EXACT SAME BEHAVIOR. IN ALL CASES, THE DEALERSHIP HAS ENDED UP REPLACING THE BRAKE BOOSTER ASSEMBLY. IN MY CASE THOUGH, THE DEALER CONFIRMED THAT MY CAR WAS ON THE RECALL LIST FOR THE BRAKE BOOSTER ASSEMBLY, BUT WHEN THEY RAN SOME DIAGNOSTICS TESTS ADVISED BY TOYOTA WHICH DID NOT REPORT ANY ISSUES AND THEREFORE REFUSED TO CHANGE THE BRAKE BOOSTER ASSEMBLY. I ALSO CONTACTED TOYOTA (CASE# [XXX]) ONLY TO BE TOLD A WISHY WASHY ANSWER. I WAS TOLD THAT TOYOTA CANNOT DO ANYTHING ABOUT IT SINCE IT HAS GIVEN GUIDELINES TO THE DEALERSHIP AND IF THE DEALERSHIP SAYS "NO" THEN SO DOES "TOYOTA". NOT TO MENTION HAVING SPENT HOURS ON THE PHONE WITH TOYOTA ONLY TO BE TOSSED SEVERAL TIMES BETWEEN DIFFERENT SUPPORTS REPS AND THE DEALERSHIP. ADDITIONALLY, I WAS TOLD BY THE DEALERSHIP TO KEEP DRIVING THE CAR AND SEE IF IT WAS TO HAPPEN MORE OFTEN. ONCE IT GETS TO A POINT WHERE I CAN FIND A PATTERN AND REPRODUCE THE ERROR WITH THE TOYOTA REP THAT'S THEN THEY WILL LOOK INTO THE ISSUE. FOR SOME REASON THEY FAIL TO UNDERSTAND THAT I AM NOT COMPLAINING ABOUT MY WIPER BLADES NOT WORKING BUT THE BRAKES, WHICH COULD PUT THE DIVER IN A LIFE THREATENING SITUATION.

SLOWLY PASSED OVER A SPEED BUMP, WHICH CAUSED A BRIEF SENSATION OF ACCELERATION (COMMON IN THIS PRIUS). THEN BRAKING WAS SIGNIFICANTLY AFFECTED, WITH BRAKE TRAVEL QUITE LONG AND STOPPING POWER DIMINISHED. ALL BRAKES WARNING LIGHTS CAME ON AND STAYED ON. PROBLEM CONTINUED UNTIL I STOPPED THE CAR AND TURNED IT OFF. WHEN CAR TURNED ON, WARNING LIGHTS REMAINED BUT WENT OUT AFTER DEPRESSING BRAKE. TOOK TO DEALERSHIP. TOLD THAT BRAKE BOOSTER PUMP NEEDS TO BE REPLACED. VIN IS OUTSIDE THE RANGE GIVEN BY TOYOTA FOR RECALL PUBLISHED ON 6/5/13. HOWEVER, SYMPTOMS ARE IDENTICAL FOR THIS VEHICLE.

WHEN HITTING LARGER SIZE POTHOLES OR BUMPS IN THE ROAD I LOSE CONTROL OF WHAT FEELS LIKE THE REAR END, ITS AS IF THE VEHICLE BRAKES GIVES WAY WHEN THE REAR TIRES HIT THE OBJECT, CAR SHIMMIES SLIGHTLY, THE BRAKES STOP WORKING FOR AT LEAST 3 SECONDS AS THE CAR LURCHES FORWARD. THE BRAKE ALSO DEPRESSES FURTHER TO THE FLOOR WHILE IT HAPPENS. THERE'S A PARTICULAR SPOT ON MY WAY TO WORK THAT CONTINUES TO CAUSE THE PROBLEM. ITS HEADING DOWN A SMALL DECLINING HILL BEFORE A TURN TO THE LEFT. IF I WERE TO TAILGATE SOMEONE AND HAVE THAT HAPPEN I WOULD SURELY HIT THEM BECAUSE THERE'S NO CONTROL OF THE VEHICLE FOR A FEW SECONDS AFTER HITTING THE OBJECT. THIS OBJECT GOES STRAIGHT ACROSS THE 2 LANES AS IF THE CONCRETE PAVING WAS POURED TOO HIGH IN A LONG HORIZONTAL LINE. I THINK IT HAS TO BE ABOVE A 4-5 INCHES OR SO BECAUSE I'LL HIT SMALLER ONES AND I'M FINE AND I'VE TESTED IT ON DIFFERENT OBJECTS, ITS HIGHER RAISED ITEMS CAUSING THE BEHAVIOR. IT HAPPENS WHEN ITS DRY, WET OR ICY OUT, BUT YOU HAVE TO BE APPLYING THE BRAKE TO REALLY FEEL IT AS FAR AS I CAN TELL. MY PASSENGER ALSO FELT THE LOSS IN CONTROL EACH TIME THIS HAS HAPPENED AND ITS BEEN NUMEROUS SINCE OWNING THE VEHICLE.

I HAVE PREVIOUSLY (2010 OR 2011) FILED A DETAILED REPORT OF THE CONSISTENT ANOMALY THAT OCCURS WHILE BRAKING ON A ROUGH SURFACE OR UPON HITTING A POTHOLE, MANHOLE COVER, ETC. IN THIS SITUATION, THE FEEDBACK FROM THE VEHICLE SUGGESTS THAT THE BRAKES HAVE DISENGAGED. BASED UPON 2+ YEARS OF ADDITIONAL EXPERIENCE, I WOULD NOTE THAT: (1) THIS ANOMALY OCCURS CONSISTENTLY, AND IT HAS NOT DISAPPEARED OR ATTENUATED, (2) I BELIEVE THAT STOPPING DISTANCES ARE LONGER THAN WOULD BE EXPECTED WITHOUT THIS ANOMALY, (3) MY PRIUS WAS MANUFACTURED AFTER THE 2010 SOFTWARE FIX, AND (4) OTHER DRIVERS OF 2010 AND LATER PRIUS CARS HAVE REPORTED THE SAME PHENOMENON WHEN I ASKED ABOUT IT (SEE BELOW). MOST IMPORTANTLY, I WOULD NOTE THE FOLLOWING SOURCE OF EVIDENCE WHICH YOU MIGHT EASILY PURSUE FURTHER. I HAVE BEEN LIVING IN NEW YORK CITY (NYC) FOR MOST OF THE LAST TWO YEARS. THE NYC TAXI FLEET INCLUDES A SIZABLE NUMBER OF TOYOTA PRIUS CARS. EVERY TIME I TAKE A PRIUS TAXI, I ASK THE DRIVER IF HE HAS ENCOUNTERED A SIMILAR PROBLEM WHEN BRAKING ON ROUGH SURFACES. IN MORE THAN A DOZEN SUCH INSTANCES, DRIVERS HAVE CONSISTENTLY REPORTED THIS SAME PROBLEM. WHILE YOU MAY NOT WANT TO TRUST MY EVIDENCE ON THIS MATTER, IT WOULD BE VERY CHEAP FOR NHTSA TO SEND AN INVESTIGATOR TO SOME OF THE LARGE TAXI GARAGES IN NYC TO INTERVIEW DRIVERS WITH EXPERIENCE DRIVING PRIUS TAXI CABS. GIVEN THE LARGE NUMBER OF MILES LOGGED BY TAXI DRIVERS, THIS COULD BE AN IMPORTANT SOURCE OF INFORMATION FROM HIGHLY EXPERIENCED DRIVERS --- WHO MUST REGULARLY CONTEND WITH NYC'S MYRIAD POTHOLES. I WOULD FINALLY NOTE THAT --- OTHER THAN THIS ANOMALY --- I LOVE MY PRIUS. IT IS A GREAT CAR. I WOULD JUST LIKE FOR TOYOTA TO FIGURE OUR WHAT IS CAUSING THIS ANOMALY AND FIX IT.

THE VEHICLE HAS A NASTY HABIT OF LOSING BRAKE PRESSURE OVER BUMPS. THIS CAN BE DUPLICATED EASILY AND IS A KNOWN ISSUE THAT TOYOTA HAS YET TO RECTIFY. SIMPLY DRIVE OVER A BUMP SUCH AS A BREAK IN CONCRETE ON A BRIDGE, POTHOLE, ETC. AND HOLD ON TIGHT.

IN THE PAST (STARTING AT 2,800 MILES) AND REPORTED NUMEROUS TIMES TO THE DEALER (HUNTINGTON TOYOTA), TOYOTA CORPORATE AND THE NHTSA, WHENEVER THE CAR WENT OVER A ROUGH ROAD SERVICE WHILE BRAKING AT ABOUT 10 MILES AN HOUR THE REGENERATIVE BRAKING WOULD CUT OUT AND GIVE THE SENSATION OF THE CAR SURGING FORWARD REQUIRING MUCH GREATER BRAKING EFFORT TO BRING THE CAR TO A STOP. THE BRAKES WOULD RESET AFTER A FULL STOP AND THEY WOULD ACT NORMALLY UNTIL THE NEXT TIME BRAKING WAS DONE ON A ROUGH ROAD SURFACE. TOYOTA CLAIMED THAT THIS WAS NORMAL BEHAVIOR FOR THE PRIUS ABS SYSTEM, EVEN AFTER THE FIRMWARE UPGRADE WAS APPLIED. THIS TIME THE BRAKES DID NOT RESET AFTER A FULL STOP AND EVERY WARNING LIGHT ON THE DASHBOARD LIT UP. THERE WAS NO REGENERATIVE BRAKING AVAILABLE. THE CAR WAS BROUGHT TO THE DEALER WHO HAS HAD IT FOR MORE THAN A WEEK, AND IS REPLACING MAJOR BRAKE SYSTEM COMPONENTS UNDER MY EXTENDED WARRANTY. I WAS TOLD THAT WITHOUT THE WARRANTY THESE REPAIRS WOULD HAVE COST ME OVER $4500. THIS HAS BEEN AN ONGOING AND DANGEROUS SITUATION, WHICH MAY BE FINALLY RESOLVED AFTER ALL OF THE BRAKE COMPONENT REPLACEMENTS. AS AN ASIDE, THE BRAKE PADS SHOW SIGNIFICANT AND UNUSUAL WEAR BECAUSE THE REGENERATIVE BRAKING DID NOT WORK AS IT SHOULD.

BRAKES FAILED WHILE DRIVING. PEDAL WENT TO THE FLOOR. VERY LITTLE BRAKING POWER LEFT. LUCKILY I DIDN'T HAVE TO STOP SUDDENLY AND WAS ABLE TO BRING THE CAR TO A STOP SLOWLY. HAD THE CAR TOWED TO TOYOTA DEALER WHERE THEY DIAGNOSED THE PROBLEM AS THE BRAKE BOOSTER / MASTER CYLINDER. THEY TOLD ME THERE WAS AIR IN THE BRAKE SYSTEM. I RECEIVED A QUOTE FOR ALMOST $2900 TO FIX THE BRAKES. I CALLED TOYOTA CORPORATE OFFICE AND ASKED FOR ASSISTANCE WITH THIS CATASTROPHIC BRAKE FAILURE BUT WAS REFUSED. SEARCHING ONLINE FOUND OTHERS WITH SAME FAILURE. IN PARTICULAR, THERE WAS A PERSON WITH 43K MILES WITH EXACT SAME ISSUE, AND TOYOTA REFUSED TO HELP HIM. THIS IS A VERY DANGEROUS FAILURE AND SHOULD BE A RECALL. PLEASE INVESTIGATE FULLY AND FEEL FREE TO CONTACT ME FOR ANY ASSISTANCE. I AM IN THE PROCESS OF REPLACING THE BRAKE BOOSTER BUT I WILL KEEP THE OLD ONE IN CASE YOU NEED IT FOR YOUR INVESTIGATION. I HAD SIMILAR ISSUE ON MY 2004 LEXUS RX330 AND THERE WAS EVENTUALLY A RECALL FOR IT. IT IS UNACCEPTABLE FOR A 3 YEAR OLD CAR TO HAVE THIS KIND OF A SAFETY FAILURE.

FIRST INCIDENT: APRIL 15, 2013 I LOST MY BRAKES WHILE I WAS DRIVING HOME FROM MY NIGHT SHIFT WORK AS A REGISTERED NURSE. I WAS AT AN INTERSECTION TWO BLOCKS FROM MY HOUSE WHEN I FELT THE BRAKE WAS FAILING. IT WAS A GOOD THING THAT I WAS DRIVING SLOW TO MAKE A TURN WHEN I FELT THE BRAKE SYSTEM WAS NOT WORKING. I WAS ABLE TO STEER IT TO A PARKING LOT NEARBY BY USING THE FOOT BRAKE. PRIOR TO THIS INCIDENT, I HEARD SQUEAKING NOISES FOR ABOUT THREE DAYS WHENEVER I STEP ON THE BRAKES. I WAS RELIEVED THAT I DID NOT GET INTO AN ACCIDENT. ACTION AFTER THE 1ST INCIDENT: APRIL 24, 2010. WE TOWED THE CAR TO DCH TOYOTA FREEHOLD, AND IT TOOK ABOUT 5 DAYS TO REPAIR THE BRAKES SO THEY GAVE US A LOANER CAR WHICH WE TRULY APPRECIATE. BUT WHEN WE PICKED UP THE CAR, THE BRAKES WERE FIXED BUT THE SQUEAKING NOISE IS STILL PRESENT, AND OUR WINDSHIELD WAS CRACKED. WE CALLED THE DEALERSHIP RIGHT AWAY TO INFORM THEM ABOUT THE SQUEAKING NOISE AND TO COMPLAIN ABOUT THE CRACKED WINDSHIELD. I WAS TOLD BY THE SERVICE REPRESENTATIVE THAT THEIR TECHNICIANS TESTED MY CAR AND DEEMED IT SAFE TO DRIVE AND THAT THEY WOULD NEVER RELEASE MY CAR UNLESS THEY KNOW IT IS SAFE TO BE ON THE ROAD. SECOND INCIDENT: APRIL 29, 2013, I LOST THE BRAKES AGAIN WHILE I WAS ON MY WAY TO WORK AROUND 7:00 PM. I REALLY GOT VERY SCARED BECAUSE THERE WAS SO MUCH TRAFFIC AT THAT TIME. I WAS ABLE TO STOP AND PARK MY CAR SLOWLY TO THE CURB WITHOUT HITTING ANYBODY ELSE BY USING THE FOOT BREAK. ACTION AFTER THE SECOND INCIDENT: SAME NIGHT, WE TOWED THE CAR BACK TO THE DEALERSHIP FOR REPAIR, AND AFTER A WEEK OF WAITING, THEY FINALLY CAME BACK TO US SPECIFYING THAT THE WHOLE MASTER CYLINDER AND BRAKE PAD ASSEMBLY IS DEFECTIVE AND NEEDS TO BE REPLACED AND WILL COST MORE THAN 4K FOR PARTS ALONE. CONTACTED TOYOTA ABOUT THIS ISSUE, AND THEY SAID THAT THEY WILL NOT ASSIST US, SINCE WE EXCEEDED THE WARRANTY PERIOD.

I PUT THE VEHICLE INTO PARK AND CALLED THE WONDRIES TOYOTA DEALERSHIP AND TOLD THEM MY BRAKES WERE NOT FUNCTIONING PROPERLY AND MY ABS WARNING LIGHT WAS ON.

I REVERSED OUT OF MY GARAGE, SHIFTED THE CAR INTO DRIVE, AND PROCEEDED DOWN THE HILL WITH CAUTION. I DID NOT PRESS ON THE ACCELERATOR. MY CAR BEGAN TO ACCELERATE DOWN THE HILL DUE TO GRAVITY AND REACHED A SPEED OF APPROXIMATELY 15 MPH, AT WHICH TIME I PUMPED THE BRAKE PEDAL BUT THE CAR WOULD NOT STOP OR SLOW DOWN, AND IT CONTINUED MOVING DOWN THE HILL. AT THE BOTTOM OF THE HILL, AFTER TRAVELING APPROXIMATELY 1/4 OF A MILE, I TURNED RIGHT INTO A SMALL STREET WITH A SLIGHT INCLINE IN ORDER TO STOP THE MOMENTUM. MY CAR SLOWED AND I PUT ON THE EMERGENCY BRAKE AND PUT THE CAR INTO PARK. I CALLED MY BROTHER FOR HELP. WHEN HE ARRIVED, I TURNED THE CAR ON TO SHOW HIM THE FLASHING ABS WARNING. IT FLASHED FOR ABOUT ANOTHER 15 SECONDS BEFORE SUDDENLY STOPPING. MY BRAKES THEN BEGAN FUNCTIONING AGAIN THOUGH THEY FELT SPONGY WHEN I PRESSED DOWN ON IT.

GIVEN THE CONDITION OF THE ROADS IN CHICAGO, THIS IS A PRETTY REGULAR PROBLEM. I USUALLY HAVE TO PRESS THE BRAKE MUCH HARDER THAN NORMAL WHILE THIS IS OCCURRING BECAUSE OF CROSSWALKS AND LIGHTS. I THINK THIS IS A SERIOUS SAFETY ISSUE; HOWEVER, WHEN ASKING THE DEALER TO LOOK INTO THIS, THEY INDICATED THAT IT WAS THE ANTI-LOCK BRAKING SYSTEM KICKING IN, AND THAT IT WAS A PERFECTLY COMMON THING TO EXPERIENCE.

INCIDENT #1 BRAKE: ON JANUARY 17, 2013 AS I WAS ENTERING THE INTERSECTION ABOUT 20MPH, I APPLIED MY BRAKES, BUT THEY WENT STRAIGHT TO THE FLOOR AND WARNING LIGHT STARTED BLINKING. I PRESSED BRAKES VERY HARD AND CAR ALMOST STOP, THEN, ITS BRAKES GAVE UP. THERE IS SUDDEN SLIGHT "UNINTENDED ACCELERATION" AND I ALMOST HIT CAR FRONT OF ME. BUT, I AM ABLE TO MANAGE TO DROVE THE CAR INTO THE CENTER ISLAND. BRAKE WAS TOTALLY OUT, AND THE CAR STARTED DROVE BY ITSELF. I PANICKED AND PRESSED POWER BUTTON TO SHUT OFF THE ENGINE. CAR DROVE ABOUT 15 FEET AND STOPPED. AFTER THIS INCIDENT, I TOW MY CAR TO THE DEALER, THEY TOLD ME THAT LOST BRAKE IS DUE TO SHORT CIRCUIT MADE DOMINO EFFECT TO MULTIPLE COMPUTERS MALFUNCTION. THEY WILL REPLACE WHOLE COMPUTER SYSTEM, BUT SERVICE MAN WOULD NOT GUARANTEE IT WILL NEVER HAPPEN AGAIN. INCIDENT #2 POWER FAILED AND SHUT DOWN WHILE DRIVING AT HIGHWAY. ON DECEMBER, 2012 AND JANUARY 2013. I WAS DRIVING AT HIGHWAY AND TRYING TO MERGE INTO THE CENTER LINE, CAR STALLED AND PROMPTED "KEY DOES NOT DETECT" MESSAGE ON THE SCREEN.

MY PRIUS IV, PURCHASED NEW IN 2010, INTERMITTENTLY HAD A LUNGING FORWARD PROBLEM WHEN GOING OVER SPEED BUMPS, POT HOLES ETC. I WOULD HAVE TO STOP IT BY BRAKING QUICKLY, SO I DIDN'T COLLIDE WITH A CAR AHEAD. I INFORMED TOYOTA OF THIS PROBLEM WITHIN THE FIRST YEAR. THEY TESTED IT AND SAID THEY COULD FIND NOTHING. I MENTIONED THIS TO THEM ON VARIOUS OCCASIONS WHEN I TOOK THE CAR FOR ITS PERIODIC MAINTENANCE OF 5000 MILE INTERVALS. ON DECEMBER 26, 2012 I WAS STOPPED WAITING TO GO LEFT WHEN I WAS REAR-ENDED. I WENT TO PULL OVER TO THE SIDE OF THE ROAD TO ASSESS THE DAMAGE. WHEN I ACCELERATED TO GET TO THE SIDE OF THE ROAD,THE CAR TOOK OFF CRAZILY, AT A HIGH RATE OF SPEED FOR ABOUT 6-7 SECONDS, ZIGZAGGING UNCONTROLLABLY ON THE 2 LANE ROAD. IF THERE WERE CARS COMING TOWARD ME, I WOULD HAVE BEEN IN A HEAD ON CRASH. I IMMEDIATELY CALLED TOYOTA SERVICE OF SCRANTON,PA AND ASKED THEM TO SEE AND ASSESS THE CAR'S PROBLEM. THEY MADE AN APPOINTMENT AND CONCLUDED.SAID THERE IS NO PROBLEM INTERNALLY, AND SUGGESTED REMOVING THE AFTER MARKET FLOORMAT. I THEN PROCEEDED TO SHOW THEM THE SAME PROBLEMS MANY CUSTOMERS ARE HAVING WITH THE PRIUS , INCLUDING AN ARTICLE BY STEVE WOZNIAK, THE CO-FOUNDER OF APPLE COMPANY, WHO HAD ACCELERATION PROBLEMS WITH HIS 2010 PRIUS. I CALLED THE MAIN TOYOTA HEADQUARTERS LATER, EXPLAINING THE PROBLEM AND THEY TOO SAID THERE IS NO MALFUNCTION , ONLY MENTIONING THE FLOOR MATS AGAIN.. THIS IS NOT THE CASE AS THE CAR HAS HAD ACCELERATION PROBLEMS FROM THE BEGINNING AND TO FURTHER CLARIFY, I WAS ABLE TO FINALLY STOP THE CAR... THE MAT WAS NO WHERE NEAR THE ACCELERATOR. I AM AFRAID TO DRIVE THIS FOR OTHERS' SAFETY, MY PASSENGERS AND MY OWN SAFETY. I TAKE CARE OF MY CARS FAITHFULLY. YOU CAN VIEW MY RECORDS. I AM ALSO FEARFUL IF I TRADE THIS CAR, SOMEONE ELSE MIGHT GET INJURED OR KILLED. CAN YOU PLEASE CHECK AND ADVISE.

IF YOU GO OVER A BUMP WHILE BRAKING - THE BRAKES FAIL, AND YOU HAVE TO TAKE YOUR FOOT OFF THE BRAKE AND RE-APPLY IN ORDER TO STOP. THIS HAS OCCURRED NUMEROUS TIMES - AND IS A SERIOUS FLAW ON THIS AUTOMOBILE. THIS CAR IS A FLEET VEHICLE FOR MY COMPANY AND I HAVE ASKED PEERS IF THIS OCCURS ON THEIR CARS - AND THEY HAVE CONFIRMED THE SAME EXPERIENCE WITH THEIR BRAKES. WITH ALL THE TOYOTA RECALLS - I AM UNCLEAR WHY THIS HAS NOT BEEN ADDRESSED...?

I WAS IN THE RIGHT LANE TRAVELING WEST BOUND ON TENNESSEE STREET IN TALLAHASSEE, FL, AND AS I WAS GOING THROUGH THE LIGHT AT THE CORNER OF TENNESSEE AND MONROE STREET, THE TRAFFIC STOPPED JUST PAST THE INTERSECTION. AS I WAS ENTERING THE INTERSECTION, I APPLIED MY BRAKES BUT THEY WENT STRAIGHT TO THE FLOOR AND A WARNING LIGHT STARTED BLINKING. I HAD ONE OF TWO CHOICES; HIT THE CAR IN FRONT OF ME OR HIT THE CURB FOR THE SIDEWALK CLOSE TO WHERE A MAN WAS STANDING WITH HIS BICYCLE. LUCKILY I HAD JUST ENOUGH ROOM TO GO BETWEEN THE BACK-END OF THE CAR IN FRONT OF ME AND THE MAN ON THE SIDEWALK. FORTUNATELY NO ONE WAS INJURED IN MY ACCIDENT, I JUST SCARED THE MAN VERY BADLY, BUT THE REPAIRS TO MY CAR ARE PROBABLY GOING TO BE MORE THAN $4,000.

OK, THIS TYPE OF INCIDENT (LOSS OF BRAKING AT LOW SPEEDS) HAS HAPPENED REPEATEDLY IN THIS VEHICLE, DESPITE A RECALL IN 2010 AND "SOFTWARE FIX". THE DATE LISTED IS APPROXIMATE. I FELT COMPELLED TO PROVIDE THIS INFORMATION AFTER HAVING THIS HAPPEN TWICE IN THE PAST WEEK, IN THE HOPES THAT SOME PERMANENT FIX CAN BE MADE AVAILABLE, AND TO WARN PROSPECTIVE BUYERS TO BE CAUTIOUS. IN ALL INCIDENTS, WHEN TRAVELING OVER BUMPS IN A ROAD WITH THE BRAKES ENGAGED, THERE IS A SUDDEN SLIGHT "ACCELERATION", BUT IN ACTUALITY, PROBABLY JUST THE MOMENTARY LOSS OF BRAKING. THIS HAPPENS WHEN GOING OVER: (1) MANHOLE COVERS (2) POTHOLES (3) SLIGHT DIPS IN THE ROAD (FROM SUBSIDING ROAD PATCHING AREAS). DOES NOT APPEAR TO BE WORSE IN WET CONDITIONS, AND HAS ONLY HAPPENED TO ME AT LOW SPEEDS (~5 -- ~ 20 MPH). NOTE THAT ORIGINAL CARPETED MATS WERE REPLACED WITH ONES THAT FIT A BIT BETTER, AND DO NOT CAUSE ANY ISSUES WITH THE ACCELERATION PEDAL. ONCE THE BUMP IS PASSED OVER, NORMAL BRAKING OCCURS. WHEN I FEEL THIS VEHICLE MOMENTARILY LOSE BRAKING, I QUICKLY LET OFF THE BRAKE FOR A SPLIT SECOND, AND RESUME BRAKING. I HAVE GOTTEN USED TO THIS DEFECT, BUT I SURE WOULD LIKE SOMEONE TO INVESTIGATE AND PROVIDE A QUALITY RECALL FIX. THIS BRAKING ISSUE HAS HAPPENED IN NORTH CAROLINA (WHERE THE VEHICLE WAS PURCHASED) AND IN MASSACHUSETTS. THANK YOU.

WHEN I ENCOUNTER A BUMP WHILE APPLYING THE BRAKES IN MY 2010 TOYOTA PRIUS, THE BRAKES FULLY DISENGAGE MOMENTARILY. THIS CAUSES THE CAR TO JOLT FORWARD UNEXPECTEDLY. MY FOOT IS NOT COMING OFF THE BRAKE AT ALL WHEN THIS HAPPENS, SO I KNOW I AM NOT THE CAUSE OF IT. I RECEIVED A RECALL NOTICE BY MAIL IN FEBRUARY 2010 TO ADDRESS JUST THIS ISSUE. I TOOK THE CAR TO THE NEAREST TOYOTA DEALERSHIP TO HAVE THE RECALL WORK COMPLETED. IT WAS INTENDED TO FIX THE MALFUNCTION IN THE ANTI-LOCK BRAKE SYSTEM THAT CAUSED THE BRAKES TO DISENGAGE WHEN THE CAR HITS A BUMP. THE RECALL WORK WAS COMPLETED, BUT THE PROBLEM WAS NOT RESOLVED. THE BRAKES STILL DO THE EXACT SAME THING AND FULLY DISENGAGE WHEN I HIT A BUMP WHILE BRAKING. THIS IS UNQUESTIONABLY DANGEROUS AND A SERIOUS SAFETY HAZARD.

ON TUESDAY OCTOBER 02, 2012 AT APPROXIMATELY 0510 THE VEHICLE BRAKES WENT OUT AND THE BRAKE, ABS, AND STABILIZATION LIGHTS CAME ON ALONG WITH ALARM. VEHICLE WAS TOWED TO TOYOTA DEALERSHIP FOR REPAIR - TOLD IT WAS THE MASTER CYLINDER. VEHICLE PICKED UP ON MORNING OF OCTOBER 4, 2012 FROM DEALERSHIP DROVE APPROXIMATELY 20 MILES AND THE EXACT SAME THING OCCURRED. BRAKES, ABS, STABILIZATION ALARMS CAME ON. TOYOTA DEALERSHIP WAS CALLED AND SAID THAT THE VEHICLE SHOULD BE FINE - SYSTEM HAD CLEARED WITH PART REPLACEMENT - "MAYBE IT WAS A BAD PART OR THERE COULD BE AIR IN THE LINES." VEHICLE IS PRESENTLY AT THE DEALERSHIP AWAITING INSPECTION. FORTUNATELY, NO ACCIDENTS OR INJURIES OCCURRED ON THESE DATES. HOWEVER BECAUSE OF THE LOSS OF BRAKES AND NEAR ACCIDENTS THIS VEHICLE IS NOW A THREAT TO MY SAFETY. SO FAR I HAVE BEEN LUCKY - I DO NOT WANT TO TAKE A CHANCE WITH THE THIRD BEING THE TIME THAT I AM IN A SERIOUS ACCIDENT.

TRAVELING ON PARKWAY WHEN WE WERE APPROACHING A VEHICLE GOING SOUTH DOWN AT APPROXIMATELY 55 WE WERE TRAVELING 72 WITH CRUISE CONTROL ENGAGED, I TAPPED THE BRAKES TO TRY AND SLOW AND NOTHING HAPPENED I THEN HELD THE BRAKE PEDAL DOWN FOR MORE THAN 15 SECONDS WITH NO SUCCESS, TRIED TO DISENGAGE THE CRUISE BY PULLING BACK ON THE HANDLE ON THE STEERING WHEEL AND STILL IT WOULD NOT DISENGAGE, WE STRUCK THE TRUCK AT 72 MPH ONLY BECAUSE WE HAD NO WHERE ELSE TO GO AND THE VEHICLE WOULD NOT DISENGAGE CRUISE. THE CRUISE CONTROL LIGHT WAS STILL ILLUMINATED AFTER THE VEHICLE CAME TO REST AFTER IMPACT AND THE VEHICLE BRAKES STILL DID NOT APPEAR TO FUNCTION, THIS VEHICLE WAS A TOYOTA LEASE AND WAS TOLD MULTIPLE TIMES BY TOYOTA THAT THE ISSUES WAS RECALLED BY TOYOTA AND THAT THIS VEHICLE HAD THE RECALL PERFORMED.

TURNED ON CAR AND NOTICED ALOT OF THE DASHBOARD LIGHTS STAYED ON. AS I PRESSED THE BRAKE PEDAL IT FELT WEIRD AND ONCE I PUT THE CAR ON THE DRIVE GEAR I TOTALLY LOST BRAKE CONTROL, THE CAR KEPT MOVING AND I WAS NOT ABLE TO STOP. I HAD TO SHIFT TO "PARK" AND RISK THE TRANSMISSION BUT BETTER THAN RISKING MY LIFE... I CALLED A TOWING TRUCK. THE CAR IS AT THE TOYOTA DEALER AND I DON'T THINK THEY HAVE A CLUE OF WHAT'S WRONG WITH IT.... WE'LL KEEP YOU POSTED.

THE UNINTENDED ACCELERATION ACCIDENT HAPPENED ON 7/18/2012, ~6:20 PM AT COMPANY'S PARKING LOT. I BACKED MY 2010 PRIUS SLOWLY. THEN I SAW A CAR COMING ON MY WAY. BUT BEFORE I TOOK ANY ACTION, THIS PRIUS SUDDENLY STARTED ACCELERATING, IT WENT WILDLY, AND TURNED MORE THAN 360 DEGREE BACKWARD IN THE PARKING LOT IN JUST A FEW SECONDS. SINCE THE CAR PARKED BETWEEN A BUILDING AND A SLOP, FROM THE FRONT MIRROR, FIRST, I SAW THE BUILDING WALL AND GLASSES, THEN I SAW THE SLOPE, THEN I SAW A CAR PARKED CLOSE TO MY CAR: NO! DON'T HIT THAT CAR! THAT IS THE LAST THING I REMEMBER. BECAUSE OF THE FAST TURNING OF THE CAR AND BECAUSE I WAS SO TERRIBLY SCARED, I LOST CONSCIOUS AFTER THAT UNTIL THE PRIUS HIT THE TRUCK AND BOUNCED BACK AND STOPPED BY ITSELF. AFTER A FEW SECONDS, I WOKE UP AND REALIZED: I AM STILL ALIVE. I GOT OFF THE CAR AND SAW PRIUS PASSED THE TWO CURBS AND HIT THE TRUCK. THE TWO TIRES ON THE DRIVER SIDE GOT FLAT BECAUSE THEY PASSED THE CURB VERY FAST. I WAS SO SCARED THAT I COULDN'T RECALL OF ANYTHING FOR A FEW DAYS UNTIL WEEKEND. WHY DID THE CAR LOSE CONTROL? ONE MAY ARGUE THAT I STEPPED ON THE ACCELERATOR. THIS COULD HAPPEN TO NEW DRIVERS, BUT NOT TO ME BECAUSE I HAVE BEEN DRIVING FOR SO MANY YEARS AND ALWAYS A GOOD DRIVER. MANY TIMES I SAW A CAR ON MY WAY WHEN I WAS BACKING, I ALWAYS STOPPED RIGHT AWAY. AND I WAS HEALTHY IN A NORMAL DAY IN NORMAL MODE, ALERT AS USUAL. WHY WOULD I STEP ON ACCELERATOR WHEN BACKING? EVEN IF I MIS-STEPPED ON THE ACCELERATOR, I CAN ALWAYS SWITCH TO BRAKE RIGHT AWAY. BUT I COULD?T DO ANYTHING ABOUT THE CAR ON THE DAY. IT WAS OUT OF CONTROL COMPLETELY. AFTER I LOST CONSCIOUS, MY HANDS WERE OFF THE STEERING WHEEL AND MY FOOT DIDN'T STEP ON ANYTHING, THE CAR DIDN'T SLOW DOWN BUT STILL MOVED FAST AND PASSED TWO CURBS EASILY. SUCH A MANIPULATION CAN ONLY BE DONE WHEN THE CAR IS IN ACCELERATION, AND BY ITSELF. PLEASE INVESTIGATE IT ASAP!

2010 PRIUS BRAKE FAILURE. I WAS ABLE TO SLOW DOWN THE CAR BY REPEATED PUMPING ON THE BRAKES. FORTUNATELY, MANAGED TO CRAWL TO A NEARBY TOYOTA DEALER BY USING THE PUMPING TECHNIQUE AND HAVE MY FOOT ON THE EMERGENCY FOOT BRAKE JUST IN CASE. TOYOTA SAID I NEED TO REPLACE THE MASTER CYLINDER WITH ACTUATOR. TOTAL COST PARTS/LABOR $4100. I AM UPSET BECAUSE MY FAMILY OR OTHERS COULD HAVE BEEN SERIOUSLY HURT IF I PANICKED AND NOT PUMPED ON THE BRAKE TO SLOW THE VEHICLE DOWN. THIS IS A SERIOUS HAZARD WHICH SHOULD BE KNOWN AS I HAVE SEEN OTHER SIMILAR COMPLAINS LODGE ONLINE.

I APPLIED MY BRAKES APPROACHING A TRAFFIC LIGHT AND HIT A SMALL POT HOLE AND THE ENTIRE VEHICLE JERKED FORWARD EVEN THOUGH THE BRAKES WERE APPLIED AND NEVER TAKEN OFF THE PEDAL. I HAD TO THEN PRESS DOWN HARDER ON THE BRAKE PEDAL TO COME TO A COMPLETE STOP. I HAVE OBSERVED THIS TYPE OF BEHAVIOR WHEN THE ROAD CHANGES SURFACES AND IS LOWER THAN THE PREVIOUS SURFACE AND DIPS IN THE ROAD. THIS IS ALL OBSERVED WHILE ONLY BRAKING AT LOW SPEEDS LESS THAN 40 MPH. EVERY TIME THIS BEHAVIOR IS OBSERVED THERE IS A LOUD BANG, I AM NOT COMPLETELY SURE IF THIS IS FROM SWITCHING SURFACES OR HIT POT HOLES OR DIPS IN THE ROAD.
