2001 GMC Sierra 1500 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2001 GMC Sierra 1500

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.

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.

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.

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.

Love my truck. Bought it new. No problems and we have 130,000 miles on it. I have driven it from West to east coast not problems. I have no reason not to keep it.
