Accord

• Automatic transmission
• 100,000 miles

Yesterday my wife took the car out of the garage, got off the car to go and close the garage, as well as the gate. I was not there but my wife and son were. She said that as soon as she got off the car, the car started going in reverse, by itself at about 5mph. My wife got scared that the car would run over our son and quickly reacted being able to only put in an arm and a leg. She said she was trying to stop the car but she couldn't. The car went in reverse and broke the edge of the fence that is usually left out when open. But it didn't stop there, it kept going in the direction from which it came out, in a tilted path. It finally stopped when it crashed into our Pilot parked inside the garage. We all got very scared, especially my wife because she did not understand how the car took off by itself. She had said she left the transmission on park, but when i checked it was on reverse. It was a very odd situation because there was nobody controlling the car. Even after it broke down the fence it did not stop. Now the car driver's door wont close because of the impact it had with the fence while it was open and crashed. Also our Honda Pilot got affected too. It has a big scratch on the left front side of it and the driver's door won't open either. We still cannot understand how this occurred and we are trying to find a logical explanation but we can't. We are very worried that it might have already happened to someone else.
