EVERY ONCE IN A WHILE - IT CAN BE MONTHS BETWEEN EVENTS - OUR PRIUS MOMENTARILY SLAMS ON THE BRAKES WHEN DRIVING AT HIGHWAY SPEEDS WHILE NOTHING ELSE IS GOING ON. WE KNOW IT'S NOT OPERATOR ERROR. IT'S HAPPENED TO MY WIFE SEVERAL TIMES AND ME ONCE. WHEN IT HAPPENED TO ME I WAS DRIVING STRAIGHT AHEAD ON A DRY, LIGHTLY TRAVELED DIVIDED HIGHWAY DURING THE DAY. EVERYTHING ON THE DASHBOARD LIGHTS UP, ALARMS GO OFF, THE CAR DECELERATES LIKE I SUDDENLY STOMPED ON THE BRAKE PEDAL THOUGH MY FOOT NEVER MOVED OFF OF THE GAS, IT LASTS FOR MAYBE A SECOND AND THEN THE CAR IS BACK TO NORMAL. IT'S THE SAME EACH TIME IT'S HAPPENED. LUCKILY EACH TIME THIS HAS HAPPENED WE HAVEN'T HAD ANYONE TAILGATING US. WE'VE TAKEN IT TO THE DEALER MULTIPLE TIMES. THE FIRST COUPLE OF TIMES THEY LOOKED AT US LIKE WE WERE LOONY. THEY CHECKED IT OUT AND WE GOT IT BACK WITH A MESSAGE THAT SAID THE TECHNICIAN CHECKED THE COMPUTER AND TEST DROVE IT FOR 20 MILES AND THE CAR WAS OPERATING AS DESIGNED. EXCEPT IT HAPPENED AGAIN. WE FINALLY CONVINCED THEM THAT THIS WAS MAYBE A LEGITIMATE ISSUE AND THEY SAID THEY BROUGHT IN A TOYOTA FIELD SPECIALIST WHO CHECKED THE CAR OUT AND THEY SAID THAT THE ISSUE WAS THE PCS WAVE RADAR SENSOR THAT WAS SLIGHTLY OUT OF ALIGNMENT DUE TO BODY DAMAGE (MY WIFE HAD HIT A SMALL DEER ABOUT A YEAR PRIOR TO THAT - DAMAGE WAS MINOR AND REPAIRED AT A LOCAL BODY SHOP). AFTER THEY REALIGNED THE SENSOR, THE CAR BEHAVED ITSELF FOR ABOUT FIVE MONTHS. UNTIL YESTERDAY WHEN IT HAPPENED AGAIN.

THE HEADLIGHTS IN MY 2011 TOYOTA PRIUS HAVE BURNED OUT 3 TIMES IN THE LAST 6 MONTHS, TWO OF THE TIMES BEING AT NIGHT AND I'VE HAD TO USE MY HIGH BEAMS SO THAT I CAN SEE. WHEN I BROUGHT IT TO MY MECHANIC, I WAS TOLD THAT IT'S A DEFECT WITH THE 2010 AND 2011 PRIUS AND THAT THE ONLY WAY TO REPAIR THE ISSUE IS TO INSTALL AN ENHANCEMENT KIT, WHICH COST ME OVER $500. WHEN I CALLED TOYOTA ABOUT THIS PROBLEM, I WAS TOLD THAT MY EXTENDED WARRANTY DOES NOT COVER BURNED OUT HEADLIGHTS. I KEEP TRYING TO TELL THEM THAT I DON'T EXPECT THEM TO COVER BURNED OUT HEADLIGHTS, BUT THAT THEY ARE BURNING OUT BECAUSE OF A DEFECT WITH THE CAR. THEY KEEP BRUSHING ME OFF. I AM VERY UPSET BY THE FACT THAT IT'S A KNOWN PROBLEM WITH THE CAR AND TOYOTA IS NOT STANDING BY IT.

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.
Consequence & remedy
Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.
Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. 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. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist
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.
