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.

CITY STREET ...PRESSED ON GAS AFTER THE LIGHT CHANGED AND IT DID NOT GO FORWARD AND THEN WAIVERED FOR AWHILE. I WAS VERY CLOSE TO HOME. I DO NOT KNOW HOW IT WILL WORK TOMORROW . NO WARNING LIGHTS WERE ON. IT HAS ACTED FUNNY BEFORE LIKE THIS ON HIGHWAY TRIPS AND THEN IT WOULDN'T DO IT. TOYOTA DEALERS DO NOT EVEN KNOW ABOUT THEM AND IT IS ANNOYING. IT FEELS LIKE A TRANSMISSION SLIPPING BUT HAS LESS THAN 70,000 MILES. I THOUGHT MAYBE HEAT IS DOING IT BUT NOW THAT IT IS OUT OF WARRANTY IE OVER 5 YEARS OLD, I DO NOT KNOW WHAT TO DO. I AM UNSURE WHAT CAUSES THIS SINCE NO LIGHTS WARN ANYTHING IS WRONG.
