My wife came home from a trip and parked the car in the garage left the keys in the ignition and came inside. She heard a noise in the garage and opened the kitchen door and the car was trying to start with the key in the off position. She finally had to pull the key out of the ignition to get it to stop. She said it had done this on two other occasions a few weeks before.
