Front Air Bag Sensor Control problems of the 2003 GMC Envoy

The contact owns a 2003 GMC Envoy. When the contact turned the ignition on, the driver and front passenger side air bags deployed without warning. There was no injuries. The vehicle will be taken to the dealer for a diagnosis. The current and failure mileages were 78,000. Updated 3/5/09 there was an internal failure of the air bag module. Updated 03/10/09.

Purchased 2003 GMC Envoy slt on 11/30/2002. Service airbag light came on as I was driving the vehicle off the lot. Returned to dealer for repair. Dealer said it was a loose wire in the sensor. One month later service airbag light came on again. Returned it to dealer, could not determine problem so they replaced the passenger side airbag. Service air bag light is on again. This is the third time. Also have had intermittent problems with the brakes. When approaching a stop light have had instances where the car will not stop, and the brake pedal is to the floor this has happened 3 times. Took it into the dealer and was told this is the way the brakes function on this vehicle????? have had intermittent problems with the 4 wheel drive. The lights on the 4 wheel drive indicator will flash from 2hi all the way to 4 whl drive without every touching the control. Extremely disappointed in this vehicle for the cost and unfortunately have a 4 year lease. Will not recommend or purchase another GMC product.
