My wife came to a stop at our security gate, used the remote for the gate but it wouldn't open. She backed up about 15 feet to turn around. When she put the car in drive, it lurched forward back towards the gate and wouldn't stop when she applied the brakes. It didn't speed up and it wouldn't stop. The car was making a grinding noise as it moved along. She was jamming on the brakes and it still went right through the closed gate, pushing it open as it went. It kept going for another 40-50 feet until she thought to pull on the emergency brake. The car stopped. She turned the car off and got out, badly shaken but not injured. After calming down, she got back in the car to see if it would start. It did. She drove it two more blocks to our house. She hasn't driven it since. She's terrified it will happen again.
