2012 Toyota Prius Complaints

Almost had an accident due to the brake master, actuator and booster pump assemblies, failing. There were no warning lights alerting me to an issue. Just lost ability to break and car shut off completely while in motion.

The brake booster and brake booster pump assembly (also referred to as the Accumulater or Accentuater) have failed in my vehicle the same as Toyota's known defect that was mentioned in their Customer Support Program 20TE07 (part numbers can be found within the filing of their CSP 20TE07). I am reporting that this issue appears to have affected more than their initial estimate of ~118,960 states impacted vehicles.l because Toyota is declaring my vehicle is outside of their CSP 20TE07 although their defect endangers my safety (and the safety of others) and attempts to put their defective vehicle brake parts as my financial burden. This issue should have been/should be a larger recall. Thank you.

2012 Prius with 174,344 miles in great condition, with regularly scheduled oil changes. ABS/Break Actuator failure on freeway with no warning other than a beep a few seconds before the breaks disappeared completely. Break pads changed 4 months ago and new wheels installed as well. This is a known problem with Toyota under the TSB002419 where Break booster actuator was put on a customer service program to be fixed by the dealerships, but has since expired since 2022. The cars are still known to have their breaks go out due to this malfunction but it is now not covered by Toyota and cost $4K-$5K to fix which is more than the market value of the car today. This needs to be fixed and regulated.
