My vehicle makes a clunk noise when the vehicle is in motion and I press on the accelerator it also makes a little jerk. This mainly happens @ low speeds and on a incline hill. There some type of oil or grease stains where the cv axle goes into transmission. Ive felt my vehicle with less power and pulls to the left. Took the vehicle to Chevrolet and they said they couldnt duplicate the issue or the oil leak.

While my wife was pulling into park the car and pressing the brake, the car all of a sudden accelerated into the building. Pressing the brake failed to stop the car. No person was in the way of the car so no one other than my wife was at risk of injury. The problem has not been reproduced since the car was totaled. The car was inspected by the insurance for loss but that was it. Police and manufacturer have not inspected the car. No warnings were presented prior to the accident.
