2022 Toyota Prius

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 husband and I rented a car from Avis on June 19, 2023. THe car they we selected was not available so they picked a prius out of the lot and gave it to us. On the morning of June 20, I was slowly turning into the driveway at [XXX] , my foot on the brake the whole time to slow to a stop so I could park parallel to my realtor's car. My realtor, [XXX] , witnessed the slow speed, as did many of the neighbors, as it was a quiet residential street. I continued to depress the brake but instead of stopping, our rental car, a Toyota Prius, suddenly lurched forward through the garage door! At no time did I lift my foot from the brake from the time I slowed the vehicle to enter the driveway. My husband can attest to this. In fact, he told me he was about to remove his seat belt, as he expected we would come to a stop. THe car ended up crashing through the back wall of the garage causing extensive damage. The air bags did not deploy either. I cannot explain why the vehicle would suddenly accelerate while my foot remained on the brake. I am now being sued by the homeowners insurance company. Fortunately no one was hurt nor killed. I filed a claim initially with avis two days later and asked for a report or dcm download of the brake system. Their ins. co. is named Sedgwick and I have followed up with their reps and no one can tell me if the brakes were checked and what was found. I have never been in a crash in my life and this is extremely upsetting. No one is getting back to me. Can you please help?
