2014 Toyota Prius C Recalls, Ratings & Complaints

Incident: October 6, 2026 · Filed: October 14, 2026

The brakes failed while driving at a high speed (55 MPH) on the highway along with failing when braking at a low speed (15 MPH) near a major intersection. This occured with no warning other than the Brake, ABS, and Traction Control appearing as the failure was occuring. The warning light when away after the first occurance and the brakes began working again within a few moments. It then reoccured and the lights did not turn off and the car began beeping. My safety, along with my passengers safety and the safety of those who were in the area was put at risk. The highway failure occured in a high traffic area which was also a construction zone so workers were at risk. It has been confirmed by an independent service center that the Power Brake Booster and Brake Master Cylinder Assembly failed. There were no sypmtoms or warning prior to this dangerous failure. After researching this issue, I have found that this is a common issue but no recall has been issued, only a Customer Support Program Bulletin, of which I never received. This is extremely troubling due to the nature of brake failure at both high and low speeds can put not only the driver at risk but those who are near the vehicle experiencing the brake failure. Repairs are currently in process at the cost of approximatly $3,200.

While driving, suddenly all brake lights and warning lights went on, and brakes stopped working normally. It became difficult to brake (brake took a while to engage - had to press pedal to the floor). After diagnostics at the dealership it looks like the brake booster failed. Apparently Toyota knew about this issue as they did an extended warranty through a Customer Support Program, but unfortunately my issue occurred just past the expiration of that warranty. Since brakes are such a critical component of vehicle safety, if they don't operate well or as expected, it endangers the driver and everyone else on the road. It is wild that Toyota is aware of this issue but that there has been no recall yet.

I was told that my Brake Booster and Brake Booster Pump Assembly needed replaced. I had specifically asked my dealership in the past if there were any issues with my car and was told that there was nothing, which was untrue. I called Toyota and was told that I was mailed something back in 2018, but I do not remember receiving it. Now I am told that this has expired. I wanted to know if I had any recourse or extension time on this program 21 TE01. I am afraid that my brakes will not work, as the lights go off and on.

We were driving on a city street about 25-30mph and the car jerked suddenly and the lights on the dashboard illuminated and the "Check Hybrid System" message came up as well. The car was able to coast to a nearby parking lot. We attempted to drive the car home and the car stalled in the middle of the street. We were able to push the car off the road and then get it towed. The presented a potentially very dangerous situation as the car had a complete failure while driving in the middle of the road. The Toyota service department ran a diagnosis which returned DTC P0A94. All of this indicates that the car should be covered under the CUSTOMER CONFIDENCE PROGRAM 23TE03 however that program seems to only cover the 2010-2015 Prius and 2011-2017 Prius V models and not the Prius C. There are several reports of this same issue happening on the Prius C as well though so it doesn't make sense that it is not covered.

My 2014 Toyota Prius C experienced a complete hybrid inverter failure. The part number of the inverter is the same as the one covered under Toyota’s inverter recalls (such as Recall J0V), yet my VIN is not included. The failure created a serious safety concern, as the vehicle lost power while in motion. Toyota’s recall appears to be too limited in scope and may need to be expanded to cover Prius C models that share the same faulty part. I am requesting that NHTSA investigate this issue, as it appears to involve the same hardware defect acknowledged in other Prius models.
