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.

STARTING IN SPRING 2013 AND CONTINUING DURING THE REST OF THE SPRING, SUMMER AND EARLY FALL IN THE HOTTEST MONTHS, AFTER PARKING MY PRIUS C OUTSIDE, IT ALWAYS HAD ISSUES STARTING, WHICH CONTINUES TO THIS DAY. I WILL PUT THE KEY IN THE IGNITION, START THE CAR, ALL THE DASH LIGHTS COME ON AND THE CAR WILL USUALLY NOT ALLOW ME TO PUT IT INTO REVERSE OR DRIVE. I HAVE TO TAKE THE KEY OUT OF THE IGNITION AND START IT AGAIN AT LEAST TWICE BEFORE IT STARTS NORMALLY AS IT DOES WHEN THE WEATHER IS COOLER AND/OR WHEN THE CAR IS PARKED IN MY GARAGE. A COUPLE OF TIMES, I MANAGED TO GET THE CAR TO GO INTO REVERSE, BUT IT WAS ALMOST IMPOSSIBLE TO STEER AS IF THE PARKING BRAKE WAS ON. THEN THE VEHICLE STOPPED, LEAVING ME IN THE PATH OF ONCOMING TRAFFIC. THIS HAS BEEN HAPPENING SINCE I BOUGHT THE CAR AND THE DEALERSHIP SAYS THEY CAN'T FIX IT UNLESS THEY CAN RECREATE THE PROBLEM. I HAVE TAKEN PICTURES AND VISEO, BUT THAT MAKES NO DIFFERENCE TO THEM. THIS IS A DANGEROUS PROBLEM AND NEEDS TO BE FIXED. THIS IS THE SECOND COMPLAINT I HAVE FILED RE: THIS MATTER AS MY FIRST DOES NOT SEEM TO APPEAR HERE.

DRIVING THE INTERSTATE AT 65 MPH THE ENGINE STOPPED - WITH NO WARNING OF ANY KIND, THE AIR, DASH LIGHTS, RADIO, ETC ALL CONTINUED TO WORK. WE COASTED TO THE SIDE OF THE ROAD & RESTARTED THE ENGINE. WE PURCHASED NEW & HAD ALL THE REQUIRED MAINTENANCE DONE AT THE TOYOTA DEALERSHIP. WE LEARNED OF A RECALL ON THE NEWS IN FEBRUARY & TOOK THE CAR IN FOR THE REPAIR. (A SOFTWARE PROBLEM RELATED TO THE CAR ENGINE STOPPING WHILE DRIVING) WHEN WE LEARNED OF THE RECALL WE REMEMBERED THIS HAD HAPPENED TO US ABOUT A MONTH EARLIER, AGAIN, ON THE INTERSTATE AT 65 MPH & THOUGHT IT WAS JUST A FLUKE AT THE TIME. WE WERE VERY UPSET WHEN THIS LATEST INCIDENT HAPPENED AFTER HAVING THE RECALL REPAIR DONE ON THE CAR & HAVING DRIVEN A FEW THOUSAND MILES BETWEEN INCIDENTS. WE DROVE THE CAR DIRECTLY TO OUR DEALER'S SERVICE DEPT AND REPORTED THESE FACTS TO THE SERVICE MANAGER. THEY IMMEDIATELY TOOK IT IN AND TRIED TO DETECT ANY EVIDENCE OF THE INCIDENT. THEY TOLD US THAT THEY ALSO CONTACTED TOYOTA CORPORATE TECHNICAL SERVICES FOR ASSISTANCE. THEY WERE NOT ABLE TO FIND ANY EVIDENCE OF THE INCIDENT. AS WE ARE NOW AFRAID TO DRIVE THE CAR, THEY GAVE US A CAR TO DRIVE UNTIL THE PROBLEM COULD BE RESOLVED. WE DON'T WANT TO SEE THIS CAR SOLD TO AN UNSUSPECTING DRIVER. WE FEEL THIS IS A LIFE THREATENING DEFECT AND TOYOTA SHOULD REPURCHASE THE CAR FROM US AT A FAIR VALUE SO THAT WE COULD REPLACE IT WITH ANOTHER CAR. WE CONTACTED THE TOYOTA CUSTOMER EXPERIENCE CENTER YESTERDAY BY PHONE AND FILED A FORMAL COMPLAINT, THEY OPENED A FILE AND GAVE US A CASE NUMBER. TODAY WE WERE CONTACTED BY PHONE BY A TOYOTA REGIONAL ANALYST AND WERE TOLD THAT SINCE THEY CANNOT FIND ANY EVIDENCE OF THE INCIDENT BY USING THEIR COMPUTER SYSTEM WE WOULD NEED TO FILE A LEMON LAW COMPLAINT. WE TOLD HIM THAT WE EXPECT TOYOTA TO RESOLVE OUR ISSUE - WE SHOULD NOT HAVE TO PROVE THE DEFECT. HELP. *TR

14V053000 · Electrical System:software; Hybrid Propulsion System: Inverter

Feb 12, 2014

Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.

This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
