Sudden Unintended Acceleration: I had been out doing errands in the morning. I returned home, pulling up in front of my townhouse which is on a cul de sac. After gently coming to a stop, I planned to back up just a bit to park my car along the curb. (I did not have my foot on the accelerator, as the car normally goes gently backwards when you put it in reverse.) When I put it in R, the car accelerated backwards and crashed into a car that was parked along the curb about 15-20 ft behind me. I instinctively put the car in D to stop going uncontrollably backwards. The car shot forward; the brakes did not work. The car was out of control, making very loud revving sounds and loud screeching sounds from slamming on the brakes. Somehow, it did finally come to a stop by itself ¾ of the way around the cul de sac. Wanting to get out of the middle of the street, I instinctively turned the car back on and drove it slowly to my driveway. The car functioned normally. I could have badly injured or killed someone; in my cul de sac, there is often a lot of activity involving people of all ages, including children and babies. A police report exists. The car I hit was totaled. I had the car towed to my mechanic. He said the car didn’t throw any codes. He inspected it, but did not find anything wrong with it. The local Toyota dealership refuses to touch it because it’s been in an accident. I called Toyota (Plano TX) on 10/5: filed a claim with them on 10/7. A 3rd third-party inspector from En
