I was slowly entering a handicapped parking place right in front of a business. The distance from the front of the parking space to the building wall was about 15 feet, one car length. I approached the place to stop in the parking spot when in a split second the car violently surged forward and would have crashed into the cinderblock wall had there not been a supporting post on the building and a metal frame with equipment which stopped the forward movement. The surge was explosive, almost like the acceleration of an airplane taking off. The whole incident took a second or two. There was no opportunity for any driver response to the surge. Had we not been using seatbelts, the front seat passenger & myself would have gone into the windshield and perhaps been killed or very seriously injured. Had I not been driving toward the building when the violent episode occurred, I likely would have hit someone in the parking area and killed or seriously injured people or crashed into park cars. Our injuries were relatively minor due to the seatbelts. The passenger will need therapy on her neck and back. A week later we are still emotionally stressed. There were no indications there was anything wrong with the car prior to this incident. It had only 27,000 miles with new tires and no apparent service issues. This hybrid car, which goes about 22 miles on a charge, was about at the point when it would have transitioned from electric to use of the gasoline engine. The badly damaged car was towed to a lot and later picked up and taken to the insurance facility for evaluation. I have not yet heard back. A NYS trooper investigated. He told me twice to have the Insurance Company look at possible vehicle defects when they examined the vehicle for insurance purposes. I passed on that information, but it appears the insurance company only evaluates the car for damaged. I have not yet gotten a report back yet, but it appears the car is totaled.

Today, while driving with DRCC engaged, my vehicle followed a leading car and appropriately slowed down to 2 mph as we approached a signalized intersection. However, when the leading vehicle changed lanes, a gap was created between me and a new lead vehicle, which was fully stopped. Despite this, the DRCC system accelerated to 5mph and collided with the stopped vehicle.

A sticky accelerator caused my 2021 Prius to lurch forward into a wall. I was pulling into a parking place when this happened. The front airbag deployed. This is the second time this has happened to me with a Prius. In my previous Prius it happened to me two years ago. Both times the vehicle suddenly lurched forward. It was terrifying.
