I am reaching out to you because my car is at the dealer, nothing has been done to fix the problem, and I refuse to take my car back at this point. I paid cash for this car and this is the second time it has been in for the same problem. On monday afternoon I pulled into my bank with cars in front of me and beside me. I came to a stop, had my foot on the brake and all hell broke loose. My car lunged forward, my engine was screaming, my speedometer said 80 MPH, I had both feet on the brake to not hit the woman in front, my rear wheels were smoking and screaming and my car was jumping side to side because of the spinning wheels and nowhere to go because at this point I am standing on the brake with both feet. Someone screamed turn off the ignition and the moment was over. Courtesy chevrolet in salisbury md, just called to say the problem didn't throw a code so cadillac won't pay them to look and fix the problem. If they won"t fix what's wrong they can keep the vehicle and I want my money back and as I told them I won't stop until I get someone to listen and warn others of this problem. I have researched the internet and this is a very serious problem widespread and these cars need to be recalled.

After backing the vehicle in to a parking spot I wanted to straighten it out. When I put the car in drive there was a loud shrilling noise (sounded somewhat like brakes peeling) and the car accelerated forward with my foot on the brake. I pumped the brakes in an attempt to stop the vehicle but every time I pushed the brake the car would buck forward. In a matter of seconds the vehicle crashed in to a wall. This whole incident was less than 10 seconds. I would like to note this was a loaner vehicle. I would also like to note that the floor mats for this vehicle were in the trunk of the car and cardboard with plastic wrap over it was being used in their place. I don't know if that had anything to do with this but wanted to make you aware. The vehicle instantly began leaking fluid and had to be towed to the dealership. The tow truck driver made a comment that there was something wrong with the vehicle. Updated 02/07/12
