I experienced an acceleration in my 2008 Cadillac CTS while parking in a parking lot. Car hit a building doinc considerable damage to the building. Can you me what may have caused this to happen?
My foot was on the brake when all of a sudden the car lurched forward with the motor racing. Could not stop it from moving forward even though my foot was on the brake. I don't have a picture of the car.
by riding around parking garage, most likley with your left foot on brake pedal and right foot on the go pedal, with the car in this condition , your losing vaccum or the vaccum is getting very low, witch means no assist from brake booster, witch means no brakes. only pump brakes if you have to, to let vaccum build back up , and regain your braking power.
