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.

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 to be an extraordinarily amount of good luck as I could have been easily rear-ended the other night. Curiously, in this NHTSA data base, another owner reported an incident (11439720) on November 8, 2021, that is similar to the experience I had just days prior. And our VINS are eerily close. Coincidence? Not likely. Does the 2014 recall apply to my car and if not, why not given I experienced the exact same symptoms?

I TURNED ON MY VEHICLE AND WHEN I SWITCHED GEARS, FROM PARK TO DRIVE, IT DID NOT REGISTER THAT IT WAS IN DRIVE. WHEN I TRIED TO DRIVE AWAY, THERE WAS NO ACCELERATION AND LACK OF POWER. MY BATTERY WAS OPERATING AT ALMOST MAX CAPACITY.

ALL FOUR DOOR LOCK ACTUATORS HAVE FAILED ON MY 2014 VEHICLE. TOYOTA DENIES ANY KNOWLEDGE OF THIS AS A COMMON PROBLEM, BUT THE INTERNET SHOWS THAT IT IS A PROBLEM AFTER ONLY 3 OR 4 YEARS OF PURCHASE OF A BRAND NEW VEHICLE. REPAIR COSTS ARE VERY HIGH FOR EACH DOOR FOR THIS PROBLEM. THERE IS ONLY ONE DOOR WITH KEY ENTRY.
