All the gages have stopped working correctly. They do not report proper information to driver . The electrical wiring to the rear wiper, license plate lights and rear hatch stopped working. The most dangerous thing is the ABS brake system dash lights and bell comes on every time the car is driven and the brake pedal goes to the floor when trying to stop.

While driving in a 40 MPH zone I glanced at the speedometer and it read 70 MPH! I immediately applied the brakes to slow the vehicle down before I realized that the speedometer indication was inaccurate. Upon coming to a complete stop the speedometer indicated 40 MPH. This happened several times before resuming normal operation. Since then I have noticed the gauge "sticking" when letting off of the gas pedal. This is creating an un-safe condition for myself as well as the occupants of this vehicle. I do not know when the speed indication is truly accurate. I have since learned that this is a common defect on this vehicle as well as other gm models made during this time frame. There should definitely be a recall on this problem before an accident occurs.

The gas gauge stays on empty when there is a full tank of gas. There rear windshield wiper comes on by itself. The radio plays like it is in a tin box. Every so often it will play normal. But most of the time it doesn't. This happens when it is moving or in park.
