general problems of the 2004 Cadillac CTS

I have a 2004 Cadillac Cts I have replaced the ecm, throttle body 3 times, gas pedal, wiring harness for the throttle body, but the throttle body position will be learned for about a month then my vehicle would go into limp mode almost causing several car accidents. I have tried just about everything I have had the engine replaced as well. I don't want to let this vehicle go but this issue will not stop. It is a huge safety issue and I need it fixed before me or one of the other gm owners lose their lives.

Vehicle has twice accelerated forward upon braking when coming to a stop. First time was in a parking lot. Vehicle was pulling into parking space, slowed to a crawl with the brakes applied, then suddenly lunged forward, hitting the car parked directly in front of vehicle. No damage occurred, but experience very frightening. Second time was returning from doctor appointment. A passenger in the vehicle at the time and experienced the defect. While coming to a stop behind a group of cars at the stop light, brakes applied to slow the car to a crawl, then suddenly the car surges forward. Upon slamming brake fully to the floor, the vehicle stopped, missing hitting the car ahead and stopped by only inches. Vehicle was taken to dealership, which kept the car over the weekend, supplying a loaner car. Called dealership Monday afternoon. Told there was nothing wrong with the vehicle. It was driven a total of 80 miles over the weekend and the problem was not recreated. The trouble is, it was almost 450 miles between the first problem occurrence and the second one. They were almost one week apart. Now I am told by the dealership that since the computer found no defects over the weekend, my car is ready for me to drive. I now have a defective car with a serious safety issue, which I am afraid to drive. I told them I wanted a piece of paper stating the car was free of defects, so when this occurs again, I will be notifying my insurance company and we will take action against this dealership if any damage results from another occurrence of this type. I am also going to request the dealership to allow the computer to stay hooked up to the car for at least a week when I go tomorrow to pick up the car.
