2013 Toyota Prius V service brakes problems

“My Prius had brake warning lights come on around December 2025. Turns out the brake accumulator had an internal leak. After doing some research, I discovered this was a known brake booster issue that Toyota has not issued a recall on. They do have an extended warranty program, but my vehicle did not qualify. The warning lights did not come on until after the 10 years or 150k miles cutoff for the warranty. Toyota's refusal to issue a recall and limits of their warranty program are clearly a move to avoid paying for repairs incurred as a result of defective manufacturing. Why should I be ineligible for reimbursement just because my vehicle is 13 years old rather than 10? Please make Toyota issue a recall or extend their Customer Support Program No. POL18-03.”

“Suddenly Cars Brakes failed with vehicle almost lunged forward. I had to slam the brakes heavily for it to stop; Took the vehicle to Toyota Service and clearly its a QUALITY issue toyota acknowledged as a know problem with error code C1391. They even had customer support program 20TE07 acknowledging it as their issue; I almost got killed for this. The repair costs are abnormally high at 4900$'s putting me a financial burden also and currently unsafe car; Toyota - they literally KNOW THIS ISSUE and still put me at risk. They are refusing any kind of assistance to help too.”

“When I'm in the car, the brake booster keeps recharging with out touching the brake pedal. Also, the car has problems when I apply the brakes while driving. They make a hissing and popping noise and the braking is spongy. I have had braking warning lights come on as well. It is similar to what others have been describing as the brake booster and pump actuator issue with these Prius V cars. This has been happening ongoing for about two years or so. I called the Toyota dealership and they would not check it out for free or remedy the issue that was part of their Customer Support Program (Policy 13V-235) for booster pump issues.”

“Upon a hard (but not emergency) brake, my ABS and brake warning lights came on and my car began whirring once every few seconds. I immediately took the car to the Toyota dealership, who informed me that my master brake cylinder and booster had to be replaced, and that issues with the booster were something they had seen frequently in this generation of Priuses. I paid $5095 for repairs and inspection, but I had no other choice, as my brakes could have gone out at any moment whilst I was on the road and caused a very serious accident.”

“The brake actuator and compressor is having repeated problems and causing the brakes to lock up completely while driving both in city and ON THE HIGHWAY. Abs/parking/normal brakes The lights on the dash all start flashing and beeping. ABS / emergency brake / exclamation warning / sliding / lights all on It also caused the speedometer to stop working and most of the lights of the computer part of my dash to not display information Problem code 1391 confirmed by mechanic This is a danger to me and other drivers and Toyota needs to take responsibility for these repairs because it can cost us our lives.”

“The ABS brake actuator in my 2013 Prius V failed at just over 91,000 miles in December 2025, making the vehicle unsafe to drive. I understand that this is a known issue with this model of vehicle.”
