During a trip from new mexico to arkansas, I was driving with the cruise control on. Suddenly the cruise control caused the vehicle to zoom. This has now happened a total of 8 times. One time I was in a place to see how far it would go. From a speed of 65, the transmission suddenly downshifted and the car accelerated to 90 miles per hour. It disconnected when I hit the brake. On two other occasions, while driving on this trip, after disconnecting the cruise control by applying the brake, the cruise control suddenly reconnected with out any input from me. I feel that these type uncommanded inputs are dangerous and ask for an investigation to see if this is a common problem with gm vehicles.

Dt*: the contact stated while driving 30 MPH, the engine revved and the vehicle accelerated without warning. The speed of the vehicle topped out at 40 MPH. The brake was depressed using excessive force, which was unsuccessful in slowing the vehicle. The ignition was shut off, and the vehicle was coasted into a parking space. When the vehicle was restarted, the throttle immediately opened up, revving the engine. The vehicle was shut off again, and the cruise control was disconnected at the throttle by the contact, which corrected the problem. A service dealer was notified of the problem, however the vehicle was not taken in for service.

On a recent trip to delaware, on several occasions when attempting to set or resume speed, the speed increased rapidly until the cruise control was manually disabled. My vehicle is a 2001 buick park avenue. Gm service bulletins 120901 and 030604056 describe the problem but do not classify it as a safety defect. I believe the incidents would have been serious had we not reacted quickly.

The vehicle shifts hard in gear after the initial start up. Consumer had the vehicle towed and checked at the parent company. The transmission went through several tests but the problem could not be duplicated. Since that time, the solenoid and transmission have been replaced. One week later the transmission failed and had to be completely rebuilt. Again, while driving, the vehicle made two hard jerks and would barely move. When putting vehicle in reverse it will hit hard twice and go backwards, when putting it in forward gear it will take off slowly. After traveling for a while, the check engine light illuminates and the cruise control will not work once the light has illuminated, if the vehicle is shut off for an hour or so, the problem will rectify itself until the vehicle is drivin 15-20 miles, then the same process occurs all over.
