I OWN A NEW 2013 TOYOTA PRIUS V-5. WHILE ON THE FREEWAY TAKING AN INTERCHANGE. I HAD CRUISE CONTROL SET AT 65 MPH, DISENGAGING IT AS I APPROACHED THE INTERCHANGE THAT SLOWS TO 35 MPH DUE TO THE CURVE. I WAS COASTING WHEN THE CAR SUDDENLY BRAKE, INTERNAL WARNING LIGHT FLASHING, ALARM BEEPING AND SEAT BELT LOCKED UP. I WAS ALONE IN THE CAR (THANK GOD) WITH NO CARS BEHIND ME OR IN FRONT OF ME. IT WAS AN EXTREMELY WINDY DAY AND WAS TOLD BY TOYOTA THAT IT IS POSSIBLE SOMETHING BLEW IN FRONT OF THE SENSOR. THAT IN ITSELF IS ANOTHER SAFETY ISSUE. CAN I NOT DRIVE MY CAR ON A WINDY, RAINY OR SNOWY DAY, IN FEAR OF THE PRE COLLISION SYSTEM MISINTERPRETING WHAT IS IN FRONT OF THE SENSOR? I IMMEDIATELY TOOK THE CAR TO THE DEALERSHIP ONLY TO BE TOLD TODAY THAT THEY COULDN'T FIND ANYTHING WRONG AND THAT I AM MORE THAN WELCOME TO TAKE A DRIVE WITH THEIR TECHNICIAN TO SEE IF I CAN REPLICATE WHAT HAD OCCURRED. I INQUIRED IF THE EDR HAD RECORDED THE EVENT AND THEY TOLD ME NO. IS THERE SOMETHING WRONG WITH THE EDR? SHOULDN'T IT HAVE RECORDED SOMETHING LIKE THAT? I CAN'T UNDERSTAND WHY THE PRE-COLLISION SYSTEM (PCS) WOULD ACT AS IF IT WERE TRYING TO PREPARE FOR IMPACT IF THERE WAS NOTHING IF FRONT OF THE VEHICLE. I COULD HAVE BEEN REAR ENDED OR LOST CONTROL OF THE VEHICLE. THIS IS A SERIOUS SAFETY ISSUE. *TR

AFTER BUYING A NEW 2013 TOYOTA PRIUS I NOTICED THAT THE DRIVERS HEADREST WOULD WORK ITS WAY UP TO THE HIGHEST POSITION AT ANY SPEED, NOT JUST THE SPEED LISTED AT THE TIME OF INCIDENT. MAKING THE A POTENTIALLY FATAL DESIGN FLAW, I AM CONCERNED THAT IN A FRONT OR REAR END COLLISION THIS DEFECT COULD EITHER SNAP, BREAK OR INCREASE THE POSSIBILITY OF EXCESSIVE INJURY TO MY NECK. I TOOK THE CAR BACK THE DEALER SHIP AND WAS TOLD THAT THERE WAS NOTHING THAT COULD BE DONE ABOUT IT. THE SERVICE MANAGER ([XXX]) IT WAS A DESIGN FLAW. I HAVE OWNED A 2008 PRIUS WITH NO PROBLEM, MY WIFE'S 2010 PRIUS HAS NO SUCH PROBLEM EITHER. I AM WANTING THIS DOCUMENTED SO THAT IF I AM INVOLVED WITH THE ABOVE MENTIONED ACCIDENT TYPE THAT SOMETHING MAY BE DONE ABOUT THIS.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2013-2015 Prius and 2014-2017 Prius V vehicles not included in recall 18V-684. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.
Consequence & remedy
Consequence: An unexpected hybrid power system shut down may increase the risk of a crash.
Remedy: Toyota will notify owners, and dealers will perform a software update for the hybrid system. If the vehicle has experienced an inverter failure with certain hybrid system faults related to this condition, the inverter assembly will be repaired or replaced, prior to software update. All repairs will be performed free of charge. This recall began July 24, 2020. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is 20TB10 / 20TA10.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.
Consequence & remedy
Consequence: If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.
Remedy: Toyota will notify owners, and dealers will update the software for the motor/generator control electronic control unit (ECU) and the hybrid control ECU as necessary, free of charge. The recall began January 22, 2019. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0V. Note: The software updates in this recall are needed even if the vehicle had the software previously updated under recalls 14V-053 or 15V-449.
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.
