Pulling into a parking space at walgreens about a foot from a complete stop car suddenly accelerated up over a 6in curb across a 5ft sidewalk into a concrete wall of the store, causing severe bumper damage and breaking a shallow hole in the brick wall. A lot of acceleration. Had to tow car, what happens when car is fixed and have to drive it again?

Was about 2 tenths of a mile from a stop sign. As I was beginning to make my approach, the car accelerated, lurched forward and sped across a four lane highway before I could react. The car was T-boned on the passengers side. The impact straightened my vehicles trajectory from 90 degrees to about 30 to 45 degrees. I then impacted a guardrail with a somewhat nearly head-on angle. After I went through the guardrail I then impacted a tree head-on which brought the vehicle to a stop. My passenger's side curtain air bags deployed but the front (dash) air bags did not. My passenger received a broken collar bone, fractured rib, scalp lacerations (stitches), a concussion and multiple bruises from head to toe.

Vehicle sudden acceleration after pressing brakes and trying to park: As I was turning into a parking space (less than 5 mph), in front of a grocery store to park the car, the vehicle suddenly accelerated, hit a lighting pole and completely damaged the front of the car. Pressing the brakes even harder could not stop the car. The car finally came to a halt as it hit the pole (thankfully no one was injured). The air bag did not come on, my head and neck hit the brakes. Thankfully, I was not injured and no one else was either. Brakes completely failed, the manufacturer was made aware of it but could not find anything defective in the car. This is very scary.

My wife was trying to park her car when the car suddenly accelerated without her touching the gas or the brake. Luckily, she was able to stop by slamming on the brakes. I've heard recent cases of people not being able to stop when this happens.
