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.

I was parked. I put my car in reverse. I heard the beeping sound confirming it was in reverse. I put my foot on the accelerator and the car went forward instead of reverse. This happened twice. I immediately shut off the car and turned it back on. Then it worked fine, and continued to work fine for the rest of the day as I drove to 7-8 more stops where I shut off the car. This was witnessed by a friend who confirmed that he heard the beeping sound for reverse, yet the car moved forward when I pushed on the gas. It definitely was not any kind of user error.

I've have to take my 2019 Prius Prime (with 20,000 miles total) in twice for brake issues in 6 weeks. Each time the dealer had to deal with a rotor heat issue. The first service was on 3/29/2021, the initial reason for appt was hearing squealing from the front. Upon inspection dealer found major heat marks and deep scratches/grooves as well as the rear rotors had deep scratches as well . All 4 rotors were resurfaced and the brake pads were “scuffed” during the service. At that time all brakes were inspected with the front brakes having 9mm and rears having 8mm of pads. I started hearing grinding a grinding sound about 2 week later. I took my car in for service on 5/11/2021 where the dealer …
