I had just driven up a steep driveway and made a slightly sharper than 90 degree turn at a very low speed to pull into a home parking spot when the car lunged forward suddenly and slammed into the stone wall of the house at a high speed. The section of this driveway after the turn is only 2.5 car lengths, but the car picked up enough speed to smash the front of the car in. The car was totaled and driver and side curtain airbags all deployed. I do not know why this happened as there is no way I would have hit the gas hard while pulling up to a building to stop. I also would not have slammed on the gas thinking it was the brake since there would have been no reason to slam on the brake when I was only going 5-10 miles per hour max around the tight turn. My shoe was not caught on a pedal, both sandals were still on my feet after the accident. I am not a two footed driver. I feel that it was an accelerator malfunction, as the gas pedal had always been a little strange with a delayed response, but may have also involved the transmission after driving up the steep hill and then returning to a short but flat stretch leading up to the house. I was very bruised up, particularly my shins and ankles. Two months later, I still have some visible bruising. I also had injuries from the seat belt on my chest and what appeared to be a powder burn from the airbags. I was quite traumatized by the sudden acceleration and violence of the crash and not understanding how or why it happened. If someone had been standing in front of the house to greet me on my return, they would have been killed. The car was towed away and totaled by the insurance company, so the problem hasn't been reproduced or confirmed. There were no warning lamps or messages that I'm aware of prior to the incident, except that the gas pedal has always felt inconsistent concerning when it engages. My phone self-dialed 911 and law enforcement came out to do an accident report.

I was turning into Starbucks at a low speed when the next thing I knew the car jumped forward and hit the car in front of me not one time but three times. I was finally able to get the car stopped but had Damage to both cars. I believe the accelerator was stuck causing the accident. I want to know if there is a recall on the accelerator petal that it would have caused the highlander to do this because to me this was a frightening site to go through.

I was involved in an accident that I believe was caused by sudden unintended acceleration (sua). In a very busy commercial parking lot, I was pulling into a parking space proceeding at a very slow speed, when there was a sudden surge in acceleration accompanied by a grinding/acceleration sound. I hit the brake to no effect, and the vehicle jumped the curb and hit a building shop and entered the shop. The air bags did not deploy, and I was shaken up but not injured. Thankfully, there was no one at the front desk area of the business. The car was not drivable and was towed to a body shop.
