261 complaints have been filed with NHTSA for the 2014 TOYOTA PRIUS. Below is a breakdown by vehicle component.
Most Recent Complaints
The brake booster/accumulator failed on my vehicle. This part was a common failure during the 2010-2015 production run so much so that Toyota extended coverage to replace. Mine failed recently beyond the warranty extension of 10 years/150k miles. My vehicle has only 108k miles and is 15 months beyond warranty. Toyota Corporate will not replace this vital part, despite the fact it was a defective design. I can’t drive it any longer since I don’t have the $4000 to make repair. Toyota Corporate has shown little concern despite this critical safety defect.
The slip notification, abs, and brake lights turned on while driving on the highway. The brakes then became very stiff and the vehicle did not brake as fast or as well as it normally does without the lights.
2014 Prius HB with 135k miles , onboard system warning lights for Brakes, ABS system, TPMS and Traction Ctrl all came one suddenly. Brake losing pressure while vehicle making strange noise under front driver side
On Jan 5, 2026 I was driving locally at about 40-45 mph. All of a sudden 3 indicator lights came on ABS, Brake, and Brake System Warning Light. There were no noises, but the brakes felt different. They did stop when needed. I left space between myself and others just in case, did not want an accident. Called my regular mechanic. They advised to not drive the car, but to bring it into the shop at 8am the following day. On Jan 6th, the mechanic stated it was beyond their expertise. It was towed to the local Toyota Dealer for repairs. It ended up being the Brake Booster and Pump. Upon investigation online, we saw this was a recall, but we were not notified by Toyota.
