2001 GMC Sierra 1500 Problems
The steering may develop a clunk type noise from the upper intermediate steering shaft. Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.
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 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 1999-2003 models is #4114K (trade number).
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

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.
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.
