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.
