GMC Sierra 1500 Problems

4WD Transfer Case Position Sensor/Selector Switch May Fail

The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

Heating and AC Temperature and Air Delivery Mode Door Actuators May Fail

One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.

Fuel Level Sensor Failure

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.

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.

Audio Warning Fails To Sound When Key In Ignition With Door Open Or Seat Belt Unfastened

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.

Air Bags May Not Deploy In An Accident

The air bag sensing and diagnostic module (SDM) housing may fracture, allowing water to enter it. This can cause a malfunction of the module, and as a result, the vehicle's air bags may not properly deploy in an accident. Dealers will adjust the position of the mounting stud for the module and replace the SDM free of charge to resolve the concern.

I bought this truck brand new in October 2000. It still runs great, especially in the winter. The AutoTrac system is totally awesome for winter driving. Even with 58k miles it still drives great. The only issues I've had is the fuel pump needed replacement and the right rear rotor needed to be turned right after I bought it.
over all the truck has been pretty good, the main problems have been the ac and heater controls are not reliable and all the gauges have failed and a little rust on roof.
