“My letter to Toyota: I'm writing this in regard to an inverter issue my 2012 Prius C recently experienced. While driving last month my car completely shut down, no warning and thankfully cars avoided hitting me and I was able to get from the middle lane to be able to coast to a side street in which I had to be towed. It turned out it was an inverter issue which had to be replaced. Granted my vehicle has less than 135k even though it is a 2012. …”

“Drivers side door lock malfunction.drivers side door will not open with keyless remote or by resting my hand on the door handle which should automatically open all doors. I tried using electronic unlock button inside drivers side door and also won't open.it appears to be a bad drivers side unlock actuator which has so many complaints that its obvious this part is not built correctly. It is a safety concern because you can get locked inside vehicle.”

“When in the high 80s+ outside, my 2012 Prius C, bought new, has not started from in a stopped position, with all the warning lights on the dashboard activating &, many times, the hybrid system shutting down while I'm trying to exit a driveway or garage, city street or parking the vehicle, creating a sudden stall & leaving me in the path of oncoming traffic. Took to dealership many times & they insist my car can't be doing what it's doing because they see no codes & ignore my screenshots, pics & video. …”

“My 2012 Prius C with 90,000 miles began to lose power/speed driving when check hybrid system warning suddenly came on tonight. It was unresponsive to the gas peddle, even at full throttle. Did not allow enough time to pull to the side of a busy road before it lost all ability to drive, leaving me stalled near intersection. A stranger helped push my car off the main road until aaa sent a tow truck. Had this occurred one mile later, I would've stalled on the 25 southbound freeway going from lone tree to denver at a very busy time in the evening without warning (scary thought). …”

“I was stopped at a green light the car in front me turned left an oncoming car swerved to miss them, then overcorrected and hit me. Hit me on the front right side, they hit me with so much force they moved my car almost 6 feet sideways. None of the my airbags went off and my seat belt did not lock. I hit the steering wheel with such force I had the Toyota symbol imprinted on my chest for a day. (I was wearing 3 layers a jacket and 2 shirts).why did none of the safety features work? It was if I wasn't wearing a seatbelt, but I do have he bruises across my hips saying I was.”
