GMC Recalls

Front Suspension Control Arm Welds Fail

The front suspension upper control arms may have welds that are not sufficient, resulting in separation of the arm from the bushing. Dealers will replace both the left and right upper control arms and realign the vehicle suspension free of charge to resolve the concern.

Driver'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.

Driver's Frontal Air Bag Does Not Inflate Properly

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.
