ABS, Break and traction control lights from dashboard lit on and breaks were difficult to operate during driving, able to drive back home safely. Find out that ABS (brake booster and brake booster pump assemblies which are consider safety items), are defective and can cause accidents. When calling Toyota Customer Experience Center, they decline to honor customer support program ZJB due to my car is exceeding by 5k miles the additional limited warranty. Now I will have to pay out of pocket on known safety defective part, this should be a recall and not wait to an accident to happen.

SERVICE BRAKES
My teenage daughter was driving and almost had an accident because the brakes failed. No warning lights came on until the brakes failed. I am learning now that it is a brake booster pump that Toyota knows about it as they had issued an extended warranty on the same thing that expired last year. Toyota confirmed that my Pruis was included in the customer service program but it has now expired.

While coming to a stop there was a loss of braking power and feel. Due to the unexpected change in braking characteristics this nearly caused me to collide with the vehicle in front of me. Noticed the traction control, ABS and Brake light on dash illuminated. My local Toyota dealership has diagnosed the repair as a repair involving the brake booster master cylinder and pump assembly.

SERVICE BRAKES
On June 11, 2023, my Toyota Prius brakes failed while I was driving! The vehicle was towed to the Toyota dealership on June 12, 2023 and determined the car needed brake booster assembly with master cylinder, based on codes presented at diagnostic. Quoted repair cost of $3,544.99+tax. I am second owner of this vehicle, which was purchased December 2020 from the same dealership. I was never notified about this pending issue from Toyota North America or from the dealer. I contacted Toyota North America on June 13, 2023 and was denied repair because Consumer Support Program 20TE07 expired May 2022. This Consumer Program should have been a recall. Brake failure is a major safety issue.

SERVICE BRAKES
Brakes failed while I was slowing down for a speed trap; if I had been stopping for traffic I would have been in somebody's back seat. There was already a class action lawsuit about this that Toyota settled out of court. We were supposed to receive notice about the extended warranty related to this but did not; additionally the dealership lied to us on two different occasions about our brakes being fine after they started behaving differently. If the dealership hadn't lied in both 2020, and 2022, my life wouldn't have been in jeopardy, and we wouldn't be paying thousands of dollars to fix a defective part. Why are you putting so many people's lives at risk by not forcing Toyota to issue a recall? All their hybrid braking systems over a decade of models have this issue. The hybrid specialist mechanic we ended up with said he sees several cars a week with this issue.

The Brake Actuator and Brake Accumulator were covered under a customer support issue until 5/18/22 On our car they are charging me $2600 to fix this issue. The car was at Toyota years earlier for a recall but Toyota never told us about this issue. That is not fair in my opinion. And now we are being charged $2600 to fix this issue Best [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Our 2012 Toyota Prius experienced brake failure due to the Accuator and Accumulator. I contacted Toyota Corporate office, which advised it is a known problem and had a customer support program that expired last year. The Toyota rep advised me to not drive the vehicle because of the brake failure and opened a ticket advising it is a known issue. After researching online, it is a very common issue. https://www.aboutautomobile.com/Consumer-Complaint/2010/Toyota/Prius/Brake
