I pulled into my parking space in front of garage door, I came to a complete stop and positively without any doubt, put my foot on the brake. As I shifted to park, all of a sudden engine loudly revved up and car suddenly and quickly accelerated through garage door. I want to make it perfectly clear, I DID NOT HAVE MY FOOT ACCIDENTLY ON THE ACCELERATOR WHEN CAR SUDDENLY ACCELERATED. Mazda checked the car and said nothing was wrong with the car. This has happened to many other people with Mazda and other makes and people are told too many times that there is nothing wrong the car when it clearly is not human error.

The car had a (SUA) Sudden Unintended Acceleration malfunction. No, the car was totaled and towed away. My safety was put at risk as I was slowly pulling into a parking spot, eased my foot onto the brake and this malfunction caused my car to involuntarily jolt into a rampant high speed. It jumped a curb and crashed into a tree. My brake was useless in stopping this runaway vehicle. The only thing that stopped it was that tree! The airbag deployed and I was badly bruised from the airbag. Fortunately, there were no pedestrians or other cars near mine. There were no warning lights or messages before, during or after the accident. It happened so quickly because the tree was only a few feet in front of my car.
