My engine has been misfiring and Buick refuses to fix the problem. It is unsafe to drive, jerking, and getting stuck in first and second gear when trying to accelerate. I have brought it in twice to have it fixed with proof that the engine malfunction light is on, and they said there is nothing wrong. I emailed the manager in service, and he said there is nothing he can do.

I was driving on a highway at 65mph. On a straight portion of the road the engine light came on, the engine revved up to over 4000 RPM, the power steering locked up, and many other lights came on on the dashboard display. This was a very dangerous situation trying to control the car. I was forced to slow down and when I reached 40mph the power steering came back on. The engine was still running over 4000 RPM. Most of the dashboard display lights went off except for the check engine light. Had to drive under 40 mph until I got home. While this was happening my onstar sent me a notification that there was something wrong with my transmission. The car was then towed to the GM dealer. At the GM dealer they could find nothing wrong.there were no error codes in the cars computer.

Had an oil change at dealer (typical 15,000 mile check). On the return trip to home, engine started to miss, smoke was coming from back of car like oil was being burned and the engine "check engine light" came on and the car was stopped. Called dealer who had car towed to their location. While waiting for tow, I checked oil level (it was over filled by at least a quart (maybe more), dip stick was not seated properly to check oil level. When the tow truck drive arrived and hooked the car up to tow, he indicated that the passenger side bolt that holds the engine to the frame was missing. He indicated that he would tell the dealer (colman Buick) about the problem. Later on the second day at the dealer, they said they were working on the car all day and were in process of replacing all fuel injector (don't know how they could go bad in 13K miles) and the smoking of the car has been reduced (somehow oil is getting past the rings and is being burned.two days and still no car.

Driving along at approx. 55 mph on a main hiway slowed to approx. 40 mph to make a turn, when suddenly the engine stopped operating. Everything shut down, no steering, no brakes. On star did not respond, car was disabled about 5-7 minutes, tried to start several time with the key. Serious issue, had car towed to dealer, found nothing wrong and no codes were obtained from the computer system!
