I was sitting at a traffic light stationary on a city street with a steep hill. i had my foot on the break waiting for the light to turn green. my breaks started to vibrate and then went out completely and i rolled back into the car behind me.
My car was in line for a car wash at val ward cadillac parking lot. my electronic brake was on. the brake light on the dashboard indicated this. the car was in drive but stationary for approx two minutes. the car suddenly surged forward. i thought my car was hit in the back. i didn't understand why the car surged forward. my car hit the car in front of me. after the accident, the cars were separated by val ward personnel. they had to release my electronic brake in order to move my car. per cadillac, if electronic brake is engaged, it will release when gas pedal pressure is applied. my feet were on the floor of car when surge occurred. i did not touch the gas pedal. conveniently, the accident occurred right in front of the val ward cadillac body shop office. as far as i know the car was not towed, but pushed into repair shop. i will never use that electronic brake again. this should be a warning to electronic brake users. 7 mph listed below is a guess, as i went from stopped in line to surging forward. mileage listed is approximate as cadillac service records 9 days prior reflect 11,134 mi.
