IT WASN'T A WINDY DAY BUT I DROVE A LITTLE SLOWER TO WORK NOT KNOWING WHAT TO DO. 20 MINUTES LATER ARRIVING LATER THE GLASS SHATTERED LEAVING A WHOLE IN MY SUNROOF. LUCKILY THE INSIDE SLIDING CAP TO THE SUNROOF WAS CLOSED. I BROUGHT IT TO THE DEALERSHIP AND THEY SAID SOMETHING MUST HAVE HIT IT BUT WHEN I BROUGHT IT TO GET FIXED AT AN AUTO COLLISION THEY SAID IT EXPLODED. FROM THE LOOKS OF IT, IT LOOKS LIKE IT EXPLODED TO ME WITH THE GLASS POINTING UP.

BRAKE ACCUMULATOR FAILURE RESULTING IN NOT BEING ABLE TO STOP PROPERLY. BRAKES BEGAN PULSATING AND MAKING SOUNDS UNDER PASSENGER SEAT. ELECTRIC PUMPING SOUND BECAME MORE AND MORE PROMINENT OVER TIME. BRAKES FAILED AND WARNING LIGHTS CAME ON, RESULTING IN INABILITY TO STOP PROPERLY, AND HITTING THE CURB IN A PARKING LOT. THIS IS OBVIOUSLY A MAJOR ISSUE WITH THE PRIUS. SERVICE MANAGER ADMITTED THEY SEE IT ALL THE TIME. WHEN I ASKED WHY WE WERE NOT NOTIFIED IN ADVANCE, THEY SAID A 'HIDDEN WARRANTY' EXISTED, BUT YOU HAVE TO WAIT FOR THE PROBLEM TO HAPPEN. THIS PROBLEM HAPPENED TWICE IN OUR 2005 PRIUS. THANK GOODNESS WE DID NOT HAVE ANY ACCIDENTS AS A RESULT OF THE BRAKE FAILURE. BRAKES ARE THE MOST IMPORTANT SYSTEM IN A CAR, AND WITHOUT THEM, WELL, YOU CAN'T STOP. PLEASE WORK WITH TOYOTA TO NOTIFY OWNERS OF THIS DANGEROUS DEFECT IN THEIR PRIUSES FROM THE YEAR 2004 ON.

I WAS IN LOS ANGELES PICKING UP MY TWO FRIENDS ON WHITLEY AVENUE, THIS STREET IS ON A BIT OF AN INCLINE. I WAS DRIVING MY TOYOTA PRIUS AND PRESSED THE "PARK" BUTTON. INSTEAD OF PARKING, THE CAR STARTED TO ROLL BACKWARDS AND WENT INTO NEUTRAL. THE GEAR SHIRT IS SEPARATE FROM THE PARK BUTTON SO I KNOW FOR A FACT THAT I DID NOT PUT THE CAR IN NEUTRAL. I ATTEMPTED TO PRESS THE POWER BUTTON ON "PARK" BUTTON ON THE CAR. I EVEN TRIED TO CHAGE THE GEAR SHIFT TO "D" (FOR DRIVE) REPEATEDLY. NOTHING I TRIED AT THE TIME WAS WORKING AND WHITLEY AVENUE INTERSECTS A VERY HEAVY TRAFFIC STREET, FRANKLIN AVENUE SO I NEEDED TO STOP THE CAR BEFORE IT WENT INTO THIS STREET. I TURNED MY WHEEL TO HIT MY CARE AGAINST CURB SO THAT IT WOULD STOP ROLLING. THIS RESULTED IN MY CAR CAUSING A DOMINO EFFECT AND HITTING A SECOND CAR, WHICH HIT ANOTHER CAR, WHICH HIT ANOTHER CAR. IN TOTAL MY CAR AND THREE OTHER CARS WERE AFFECTED BY THIS IMPACT. MY TRUNK COMPLETELY SHATTERED AND THE STUFF FROM IT FLEW INTO THE CAR THAT I HIT DIRECTLY HIT (THIS TRUNK ALSO COMPLETELY SHATTERED). THE TRUNK OF THE THIRD CAR ALSO COMPLETELY SHATTERED. MY CAR IS NOW TOTALED AND I WOULD LIKE TO FIND OUT WHAT HAPPENED. AFTER THE ACCIDENT I WAS SPEAKING WITH PEOPLE IN THE AREA AND ANOTHER LADY INFORMED ME THAT SHE HAD SEEN ANOTHER PRIUS ROLL UNCONTROLLABLY DOWN THAT HILL AS WELL.

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.

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.

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.
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.

Opened Sep 30, 2019 · Closed Jan 21, 2021
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.
