The 2014TOYOTAPRIUS C carries 52 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 7 crashes, 0 fires, 6 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 4/5 rating, with 4/5 front crash, 4/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2014 PRIUS C is unknown or other with 8 filings, followed by engine (7) and service brakes (7). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 51 investigation files overlapping the 2014 PRIUS C, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.

2014 Toyota Prius C with 220k miles. Four warning lights came on while driving. Brakes became not responsive unless you press down very hard. Regenerative braking, went away. The Brake pump can be audibly heard turning on every few seconds.
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 Toyotaâs 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. Toyotaâs 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.
Code C1391 Master cylinder/ break booster

While driving, I received a warning "hybrid system malfunction". Within seconds, the vehicle powered off and the steering wheel LOCKED. I had no control of the car and came to an abrupt stop in lane 1 of a two lane road. I was fortunate that it was late in the evening with few cars on the road, had I been on the highway during rush hour the outcome, due to loss of power and control (steering), could have been catastrophic and perhaps fatal for me or other commuters. I note that in 2014, Toyota notified NHTSA of a recall to, "rectify software in two of the Prius's electronic control units, one for the motor/generator and the other controlling the hybrid system." Further Toyota said, "In rare circumstances, it could shut down the hybrid system itself, resulting in loss of power and the vehicle coming to a stop". This is exactly what happened to me the other night. Toyota claims, in 2014, that "it has received no reports of accidents or injuries related to the problem." This seems t
