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.

The harness webbing/strap on the Evenflo Revolve360 Slim tore without any known incident or accident causing the damage. The defect was discovered on April 15, 2026 when the seat was temporarily removed from the vehicle. Upon inspection, the harness strap was found to be nearly completely torn through and would likely not have restrained the child occupant in the event of a crash. The seat had been in regular use and had not been involved in any collision. No unusual event or misuse is known to have caused the failure. It is suspected that the rotating mechanism of the seat placed repeated stress on the harness webbing over normal use, causing it to deteriorate and tear. The seat has not yet been inspected by the manufacturer, law enforcement, or insurance representatives, but is available for inspection upon request. The seat has been taken out of service and is not being used.

The contact owns a 2013 Toyota Prius V. The contact stated that while pulling out of a parking space at approximately 15 MPH and depressing the brake pedal, the brake pedal felt spongy, but the vehicle responded as intended. The brake, the ABS, the traction control warning lights, and an unknown warning light were illuminated. The contact scanned the vehicle with a code reader and retrieved diagnostic trouble codes for the brake booster and brake accumulator systems failure. The contact related the failure to the Toyota Customer Satisfaction Program: 20TE07 (Certain 2012 - 2014 Model Year Prius V Coverage for Brake Booster and Brake Booster Pump Assemblies). The manufacturer was contacted and informed the contact that the vehicle was no longer covered because the 10-year limit was exceeded.

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.
