ELECTRICAL SYSTEM

6/21/2016 - SCOTTS VALLEY, CA
AFTER TOYOTA POWER MANAGEMENT SOFTWARE RECALL INSTALLED "POWER MANAGEMENT UPGRADE" SOFTWARE IN MY CAR I IMMEDIATELY EXPERIENCED SERIOUS PROBLEMS WITH MY IGNITION /START OF HYBRID/GASOLINE ENGINE. AFTER PRESSING IGNITION, I HAD TO WAIT 15 TO 20 MINUTES AND PRESS START BUTTON ON/OFF REPEATEDLY UNTIL THE GASOLINE ENGINE IGNITE BUT HYBRID FAILED TO START. IT IS NOT NORMAL BECAUSE A PRIUS HYBRID ENGINE STARTS FIRST NOT THE GASOLINE ENGINE. TOYOTA HAS DISABLED SOME IMPORTANT FUNCTIONS IN ITS POWER MANAGEMENT RECALL SOFTWARE UPDATE THAT AFFECTS THE HYBRID ENGINE PERFORMANCE AND FAILURE TO START. I DRIVE MY PRIUS 3-4 TIMES A MONTH AND I DID NOT HAVE ANY PROBLEM BEFORE THE RECALL SOFTWARE UPGRADE BECAUSE PRIUS OWNERS MANUAL CLEARLY SAYS THAT THE BATTERY WITH BE DISCONNECTED BY BATTERY SAVING FUNCTION WHEN YOUR CAR IS PARKED FOR LONG TIME, SEVERAL DAYS, WEEKS. IN FACT, WHEN YOUR CAR IS PARKED FOR JUST DAYS, TOYOTA POWER MANAGEMENT SOFTWARE (RECALL) IS DRAINING THE CAR BATTERY AND RECONFIGURING THE RELAYS TO POWER UP THE GASOLINE ENGINE. TOYOTA OWNERS MANUAL CLEARLY STATES THAT WHEN YOU ARE PARKED, "POWER MANAGEMENT SOFTWARE DISCONNECTS THE AUXILIARY BATTERY FROM THE HYBRID SYSTEM." HOWEVER, AFTER THE RECALL, NOT ONLY AUXILIARY BATTERY IS NOT DISCONNECTED BUT THERE ARE LOTS OF "ACTIVITY" IN HYBRID ENGINE THAT DRAINS THE BATTERIES. I CALLED THE TOYOTA SERVICE AND THEY NOW SAY YOU HAVE TO KEEP THE CAR ON A CHARGER ALL THE TIME WHEN PARKED FOR SEVERAL DAYS. OF COURSE , IT IS A HUGE SAFETY PROBLEM TO KEEP THE CAR ON A CHARGER ALL THE TIME WHEN PARKED FOR DAYS BECAUSE THE BATTERY IS HOUSED IN THE CABIN AND THE VENTILATION DOES NOT EXIST UNLESS YOU PARK YOUR CAR OUTDOORS. AT THE SAME TIME TOYOTA RECOMMENDS KEEPING THE CAR ON A CHARGER , IT ALSO WARNS OF EXPLOSION CAUSED BY CHARGING THE BATTERIES IN A GARAGE.

FUEL/PROPULSION SYSTEM

4/22/2016 - LA JOLLA, CA
I WAS DRIVING THE 2012 PRIUS ON A DOWNHILL PARKWAY AT ABOUT 40 MPH WHEN THE WARNING LIGHT CHECK HYBRID SYSTEM CAME ON. WITHIN 10 SECOND, THE VEHICLE TOTALLY LOST POWER. IT AUTOMATICALLY SHIFTED INTO NEUTRAL. THERE WAS NO BACK UP FAIL-SAFE/LIMP HOME MODE. FORTUNATELY THE CAR WAS GLIDING DOWNHILL BY GRAVITY AND EVENTUALLY WAS STEERED INTO A DRIVEWAY. THEN IT REFUSED TO GO ON READY OR DRIVE MODE. ON THIS SATURDAY AFTERNOON THE CAR HAD TO BE TOWED HOME. IT HAD TO BE TOWED AGAIN TO THE DEALERSHIP FOR SERVICE THE FOLLOWING WEEK. IT TOOK THE MECHANIC TWO DAYS TO MAKE A DIAGNOSIS THAT A FUSE ON THE MAIN DRIVE BATTERY HAD BLOWN. ANOTHER DAY WAS SPENT WAITING FOR THE PART. THE DEALERSHIP CANNOT GUARANTEE THAT THIS EVENT WILL NOT HAPPEN AGAIN. I CONTACTED TOYOTA USA. AN AGENT NAMED MICHAEL WAS COURTEOUS ENOUGH TO LISTENED TO ME AND GAVE ME A CASE NUMBER 1604142245. TO ANYONE WITH COMMON SENSE, THIS TOTAL LACK OF AN EMERGENCY ALTERNATIVE PROPULSION SYSTEM FOR EVEN A CHEAP CAR IS UNACCEPTABLE. THE DEALERSHIP CANNOT EVEN COME UP WITH A PLAUSIBLE EXPLANATION AS TO WHAT MAY HAVE CAUSED THE FUSE TO BLOW. WAS IT OVER HEATING? WAS THERE A SHORT IN SOME INTERNAL BATTERY CELLS? THIS PAST WEEK, I NOTICED THAT THE CHARGING PART OF THE OPERATION NO LONGER CAN FULLY CHARGE THE BATTERY TO THE FORMER 11.9 MILE RANGE. IT ONLY CHARGES UP TO 9.8 MILES. THIS IS A SUDDEN LOSS OF 2 MILES OF CHARGE. I SUSPECT THAT SOME LITHIUM CELLS HAVE BEEN DAMAGED AFTER THE INCIDENT. I ALSO SUSPECT THAT THERE MAY BE OTHER ISSUES AS WELL SUCH AS SOMETHING WRONG WITH THE INVERTER MODULE RELATED TO A RECALL ON OTHER MODELS OF PRIUS DURING MY SEARCH FOR AN ANSWER. I NEED ASSURANCE FROM SOMEONE THAT THIS VEHICLE IS NOW SAFE TO DRIVE. BESIDES THE CASE NUMBER FROM MY COMPLAINT TO TOYOTA USA, AAA HAS RECORD OF MY RECENT TOWINGS ON 04/09/16 AND ON 04/12/16.
