MY WIFE WAS INVOLVED IN A TWO CAR CRASH WHEN A CAR COMING IN THE OPPOSITE DIRECTION MADE AN ILLEGAL LEFT TURN DIRECTLY IN FRONT OF HER. IT HAPPENED SO QUICK THAT SHE NEVER HAD TIME TO HIT HER BRAKES. SHE WAS TRAVELING BETWEEN 30 AND 35 MPH IN A 35 MPH ZONE ON A TWO LANE ROAD. I WOULD THINK THAT AT THAT SPEED IF ALL HER SAFETY EQUIPMENT WORKED SHE WOULD NOT SUFFER ANY INJURIES. HER SEAT BELT FAILED CAUSING THE SEAT LATCH TO FAIL AND SHE ENDED UP JAMMED INTO THE BOTTOM AND UNDER SIDE OF THE DASHBOARD. SHE SUFFERED A BLOW TO HER CHEST AND INJURIES TO HER KNEES, LOWER LEGS AND FOOT. SHE HAD SURGERY ON HER RIGHT KNEE SO WE COULD GET HER ON HER FEET AGAIN AND IS AWAITING SURGERY ON HER RIGHT SHOULDER. SHE HAD A PRE EXISTING HEART CONDITION THAT WAS RAISED TO EMERGENCY STATUS AFTER THE BLOW TO HER CHEST AND SHE HAD SURGERY FOR THAT AND THEY FOUND A SHORT CIRCUIT IN THE MIDDLE OF HER HEART AND ZAPPED IT. THERE IS ONLY A 2% CHANCE IT WILL EVER RETURN. I HAVE PICTURES OF THE FAILED SEAT BELT AND SEAT. THE SEAT BELT IS IN THE FULLY EXTENDED POSITION AND LOCKED AND CAN NOT BE RELEASED EVEN BY YANKING ON IT. I AM WRITING THIS REPORT SO THIS SITUATION CAN BE CHECKED AND IF FOUND FAULTY CAN BE CORRECTED BEFORE ANY ONE ELSE GOES THROUGH WHAT MY WIFE IS GOING THROUGH.

HEAD RESTRAINT (HEAD REST) ON DRIVER SEAT DOES NOT STAY IN PLACE. AFTER I ADJUST IT, IT RISES VERY SLOWLY. IF I DO NOT CONTINUALLY READJUST IT (3 OR 4 TIMES A DAY), IT RISES ABOVE MY HEAD. I CONSIDER THIS A SAFETY CONCERN. THIS HAS BEEN HAPPENING SINCE I BOUGHT THE CAR (NEW) AND I HAVE ASKED TOYOTA SEVERAL TIMES TO REPAIR THIS DEFECT, AND THEY SAY THAT IT IS 'NORMAL'. I HAVE OWNED MANY CARS DURING MY LIFETIME, AND THIS HAS NEVER HAPPENED BEFORE IN ANY OF THEM. IT DOES NOT HAPPEN TO THE PASSENGER HEAD RESTRAINT. I DO NOT THINK IT IS 'NORMAL', AND IF IT IS 'NORMAL' FOR TOYOTA, THEN ALL TOYOTA CARS HAVE A SAFETY PROBLEM. I HAVE CONTACTED TOYOTA AND THEY JUST REFER THE PROBLEM BACK TO MY LOCAL DEALER, WHO CONTINUES TO GIVE ME THE SAME ANSWER. *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.

The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition.

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.
