I was driving my 2005 Cadillac Sts doing about 45 miles and all of a sudden my car lost control. I put on brakes and my car would not stop. I tried steering to the left to avoid trees and my car would not turn it appeared that my accelerator was stuck and my steering wheel would not turn. My car hit three trees and when it struck the third tree I kept applying the brakes it still wouldn't stop then I turned my car off and that's the only way I got it to stop. My back wheel on the passenger side came off and my car was totaled. My air bag did not deploy. I spoke with gmac claims representative and he stated that it was normal for the air bag not to deploy. He also, stated that the air bag indicated that I had applied the accelerator when I know that I did not. I am terrified from this accident and this is the first accident I have ever had and I do not drink or take drugs. I asked the representative did the black box indicate that I had to turn the car off to stop it and representative stated no, then I asked him to tell me how the car stopped. If I had not turned the car off it would not have stopped and I would not be here today. Gmac denied my claim and stated that it was my fault.

While driving my 2005 Cadillac Sts in afternoon rush hour traffic the car suddenly loss acceleration. The car would not maintain speed (60 mph) while driving on the freeway. Had to exit freeway. The car continued to operate only at idle. Everything else was working, but could not get the car to respond to the throttle pedal. Was able to slowly exit and enter a parking lot. Restarted the car and was able to drive off normally. After a few minutes the problem recurred. The dealer had the car 4 different times (over a month total) and was not able to resolve the problem. The dealer indicated a $4000 cable harness assembly has to be replaced, but did not guarantee it will correct the problem. Throttle body, throttle position sensors have been replaced without results. The car did operate normal for over a month with new throttle body. After visiting the dealer for another issue the throttle problem recurred.
