GMC ProblemsErratic Fuel Gauge Operation
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The power door lock actuators may become slow to operate or stop working completely and require replacement.
The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

GMC RecallsVehicle Equipped With Improper Inside And Outside Mirror Combinations
The vehicles were built with an improper mirror combination of no inside rear view mirror and a right hand convex mirror. Vehicles require both side mirrors being flat if no inside mirror is provided. Dealers will install a right hand flat rear view mirror free of charge to resolve the concern.
If the airbag system is in a diagnostic test mode during a crash, the deployment of the frontal airbags and seat belt pretensioners will not occur. Dealers will reflash the system software. In the event the vehicle has had a previous airbag deployment, the airbag sensing and diagnostic module (SDM) will be replaced free of charge.
The windshield wiper module ball joints may corrode and wear over time, resulting in the wipers failing to operate. Dealers will make repairs (the repair procedure is not available as of the time of this writing) free of charge to resolve the concern.
