I entered a large, strip mall parking area and was driving at the vastly reduced speed one would use in such a situation. My intention was to park my car to enter a store in the mall. I turned a corner to park on the side of the building (parking options were limited). As I entered a parking space (moving at the speed one would drive to do so; essentially INCREDIBLY slowly; moving forward into the space at almost 0 MPH and already applying the brake). Suddenly and with no warning, the car violently lurched forward at a vastly increased speed. I pressed down on the brake harder to try to stop the vehicle, but it propelled into and over the concrete curb stop and into the thick brick wall in front of me. There is considerable damage to the front end of my vehicle as a result. I was horrified at this dangerous situation. My safety was definitely at risk. I feel very fortunate that I wasn't seriously injured (and that no one, either a pedestrian or another driver, was involved in the accident). The airbags didn't deploy and I was of course, wearing my safety belt, which kept me from any severe injury. I do feel some physical injury effects this morning however (sore neck, shoulder, back; a slight headache). I'm not aware of any warning lamps, messages, etc. going off, but I must say everything happened very quickly. I've reported the accident to my insurance company & filed a claim. Given that the incident happened on the evening before the July 4th holiday, my insurance company scheduled vehicle towing (flatbed) for my car. It's my understanding that it's being stored at the tow company location & will be delivered tomorrow (Wednesday, 7/5/23) to the certified body repair facility recommended by my insurance company and chosen by me. An insurance adjuster will be doing their evaluation, likely in the next few days, at the earliest tomorrow morning. I've also advised the insurance company of these details & told them of my safety concerns and fears.

ELECTRICAL SYSTEM

1 complaint

Certain 2018+ and all later Toyota Prius C modes have a 12V battery for which there is currently no OEM or aftermarket replacement. The battery has a form factor (shape and size) that is exclusive to these vehicles and not used in any other car sold in North America. Vehicles with failed batteries (like mine) cannot be operated. Toyota should retrofit these cars to accommodate the battery used in early (pre-2017) model cars which is electrically identical and available as an aftermarket replacement item.

STEERING,UNKNOWN OR OTHER

1 complaint

IRECEIVED THE WARNING THAT "PRE-COLLISION SYSTEM MALFUNCTION" WHILE I WAS DRIVING ON THE HIGHWAY THIS MORNING. THE WARNING MESSAGE ASKED ME TO STOP THE CAR AT A SAFE PLACE AND VISIT THE DEALER. AS SOON AS I GOT OFF THE HIGHWAY, THE CAR STOPPED ITSELF, AND THE STEERING WAS LOCKED. THE CAR WAS COMPLETELY DISABLED. AFTER TURN OFF THE CAR COMPLETELY FOR A FEW MINUTES, I CAN RESTART THE CAR WITH THE WARNING MESSAGE PERSISTS. WHILE I WAS LOOKING FOR A SAFE PLACE TO PARK THE CAR, THE CAR GRADUALLY STOPPED ITSELF AGAIN, AND THE WHEEL STEERING LOCKED ITSELF AGAIN. THE CAR FAILURE AND THE FACT THAT THE STEERING WHEEL GOT LOCKED ITSELF PUT ME AND MY PASSENGER AT GREAT DANGER.
