GMC ProblemsFuel Level Sensor Failure
The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.
On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

The upper dash may crack, most commonly on vehicles in warm climates and exposed to a lot of sunlight. The common repair is to replace the upper instrument trim panel. Information on a technical service bulletin or extended warranty is not available at this time.
On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

GMC RecallsDriver's Seat Belt Fails
The tensioner cable for the driver's seat belt may be positioned such that the driver slides over it, resulting in fatigue of this cable. This could cause it to separate from the seat belt. The driver may not be properly protected in a crash if this happens. Dealers will modify vehicles to prevent the tensioner from being damaged, and will repair any tensioner that has already been damaged free of charge to resolve the concern.
The driver's frontal air bag may not inflate properly during the second stage deployment, resulting in increased risk of occupant injury. Dealers will replace the driver side frontal air bag module free of charge to resolve the concern.
The audio warning that sounds to alert the driver that the safety belt is not fastened or the door is open with the key still in the ignition may not operate. Dealers will update the radio software free of charge to resolve the concern.
