2001 GMC Sierra 2500 HD Problems

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.

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.

The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2001-2003 models is #4114K (trade number).

I bought this truck in August 2001 with 5,500 miles. Now has 152,000 miles. Engine is 8.1 liter with Allison 5speed. Don't think I'll ever part with it. Gets about 14-15mpg empty if driven sensibly, and about 10mpg pulling my 35' 5th Wheel that empty weight is 12,500#. And this truck is a 4x4. With exception of a couple minor sensor issues, It has performed flawlessly.
