2010 Cadillac CTS engine complaints

Filed Jan 3, 2014 · Brakes, Engine · 24,766 miles · VA

Since purchasing this certified pre-owned vehicle, I have noticed that the car's engine has an intermittent tendency to suddenly rev or idle very high while my foot is on the brake and I am in the process of slowing down, stopping, or pulling into a parking apace. The car lurches forward and is only controlled during those times by applying a great deal of pressure on the brake until the idle returns to normal and the car stops trying to lurch forward. I have taken the car back to the service dept. Of the dealership each time (at least five times or more), but the problem had not been duplicated until the shop foreman drove it one day and was able to experience the problem. He replaced the throttle body, but the problem continues. I complained to gm and to the virginia better business bureau because I didn't feel enough was being done to resolve the problem. Initially, gm ignored me and offered no response. When the bbb became involved, I did get a gm response. The bbb suggested the installation of a vehicle data recorder ("black box") to help in the detection of the problem. I recorded three separate incidents on the recorder. Still, the dealership attempted to point the finger of fault at me, stating that I must be driving with my feet on both pedals at the same time! I do not practice such driving habits and told the bbb so. Since the vehicle showed no further problems for a couple of days, the bbb suggested I close the file and maybe reopen later -- if my mileage qualifies to have the case reopened. I sense the bbb's resignation to support gm and the dealer, despite the fact that I have all of the necessary documentation to support my claims. I have become extremely frustrated and very nervous about this potentially dangerous defect, and nothing is being done about it. I am hoping that you can help resolve this.

I was driving to work and the car made a loud knocking noise I pulled over and the engine shut off. I called to be towed back to dealer where we bought the car and later that day I called them and they said the engine locked up. The dealer called gm and they were told to rebuild the engine. This is not acceptable. The car has about 33,000 mile on it. We have had all maintance service proformed by the dealer. What are our options?
