“The contact owns a 2022 Toyota Prius. The contact stated that while driving, depressed the brakes, brake pedal became stiff and had to apply extra force to apply the brakes. The issue occurred multiple times. The vehicle was taken to the dealer where it bent brake pedal and the bracket was bent. The vehicle was not repaired at the time of the report.

The records describe a possible crash, fire, injury, or loss of control.

“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.”
