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.

My 2022 Toyota Prius (approx. 12,500 miles) suddenly displayed multiple warning lights while driving, made abnormal noises, and lost the ability to move. The vehicle remained powered on but could not drive and had to be towed to a Toyota dealership. The dealer diagnosed a failed brake booster with master cylinder assembly and quoted ~$4,230 for repair. This is a safety-critical component that should not fail at such low mileage. Toyota has previously acknowledged premature brake booster failures in earlier Prius models (2010–2015) and issued Customer Support Program POL18-03, extending coverage to 10 years/150,000 miles for the same component. I believe my 2022 Prius experienced the same type of defect, but Toyota refuses assistance. A sudden failure of the brake booster system while driving poses a serious crash and injury risk.

My 2022 Prius LE hood latch does not work. It does not click and hood stays locked. They told me at Walmart that the hood latch is probably corroded somewhere or defective. It takes two people to open the hood. My vehicle has 54,490mi. This has happened twice now in 2 months. I have not purchased an extended warranty and this is something that should not be happening until over 100,000 miles. I've had this happen on another vehicle that was a Honda but that was because it had a lot of mileage on it. This is just a poorly manufactured defective part that Toyota decided to go cheap on and not make sure it functions past 50,000 mi. I contacted Toyota customer experience and they said that my warranty was expired and they will not be covering it. I told them that they need to make an exception because if I need to change my oil I need access to the engine. I should not be having to deal with this at such a young age of a vehicle.
