I WAS SITTING IN THE PASSENGER SEAT OF THE CAR WHILE IT WAS PARALLEL PARKED. I PRESSED THE PUSH TO START BUTTON TO TURN ON THE BATTERY SO I COULD CHARGE MY PHONE. THERE WAS NO ONE IN THE DRIVER SEAT. THE CAR TURNED COMPLETELY ON WHEN I REACHED OVER TO PRESS THE BUTTON. NOT ONLY DID THE ENGINE START, BUT WITHOUT ANYONE PRESSING ON THE BREAKS THE CAR RELEASED ITSELF FROM BEING PARKED. THE CAR STARTED ROLLING BACKWARDS INTO THE CAR PARKED BEHIND ME. I HAVE NO EXPLANATION ABOUT HOW THIS HAPPENED. I HAVE BEEN READING INTO IT AND APPARENTLY IT'S A DEFECT OF THE 2015 AND OLDER MODELS. WHEN THE CAR STARTED ROLLING BACK I ALSO STARTED PRESSING BOTH THE PARK AND PUSH TO START BUTTONS TO TURN IT OFF AGAIN. I'VE NEVER FELT SO UNSAFE IN A VEHICLE AND GOES TO CONFIRM THAT PARK AND PUSH TO START SHOULD NOT BE BUTTONS!!! IT MAKES THE VEHICLE MUCH MORE DANGEROUS NOT BEING ABLE TO OVERRIDE THOSE COMMANDS WHEN IT CHOOSES TO GO ON ITS OWN.

DP19004 · Brake Actuator Valve Wear
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 Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring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 Because the petitioner has with withdrawn the petition, the petition is denied as moot.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.
