2008 GMC Sierra 1500 Problems

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.

The distributor may develop internal faults. This can cause a rough running engine or stalling condition, the Check Engine Light may or may not illuminate. Our technicians tell us that the distributor should be overhauled or replaced to correct this concern.

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

The wiring to the washer system heater may overheat due to a failure in the heater module. This could cause other electrical features to malfunction, smoke to develop, and an electrical fire could result. Dealers will install a wire harness with an inline fuse to protect the washer heater module. This recall is expected to begin on September 12, 2008. The General Motors recall number is 08048.

its a great truck but only one problem! the wires for the headlights on the sierra always get shorts in them and everytime u get going down the road one is out!!!

I had the truck less than a yr and the transmission went out. A yr later the vent valve assembly and solenoid had to be replaced and moved and it was under warranty and still cost me over $300 to get it fixed. Now 2 yrs later the check engine light comes on and guess what its the vent valve assembly and solenoid again. Wow Chevy/GMC really use to mean quality but really not thinking so now. Pre...

Transmission had to be rebuilt at 10K and again at 20K miles. No known "fix" for the problem. This truck is pampered and gets only 7K miles a year of driving. Professional Grade... Not hardly.
