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.

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.
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.
The driver's and/or passenger's seat may suddenly drop to its lowest position because a bolt securing the height adjuster can fall out. This unexpected movement of the driver's seat could cause a distraction, increasing the risk of a crash. Dealers will replace the height adjuster bolts in both front seats to correct this concern.
In the affected vehicles, there is a flexible steel steel cable that connects the seatbelt buckle to the front seat frame. Over time the cable may fatigue and separate. If the steel cable separates, the seatbelt may not properly restrain the seat occupant, increasing the risk of an injury in a crash. Dealers will inspect and replace the affected seatbelt buckles (lap pretensioners) to correct this concern.
Increased resistance in the front seat mounted side impact air bag (SIAB) wiring harness can result in the SIAB and seat belt pretensioners not deploying as expected in the event of a crash, increasing the risk of personal injury. Dealers will replace the affected harness connections with soldered connections to correct this concern.
Dash light sometimes fail to come on at night. Radio light blinks. A/C switch only worked on high.
My In-Laws bought the beautiful van off the showroom floor at the Cadillac/GMC dealership. I had a family of four and they adopted a little girl four years older than my oldest. With all my energy, I was always borrowing the van from my dad to take all the kids to the beach, the zoo, to parks. As the kids grew older, this was the perfect automobile for every adventure, including concerts at Gal...
