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.
The muffler heat shield may become loose on the muffler causing a rattle or popping noise. Our technicians tell us there is a kit available from GM to correct this problem.
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.

The wiring to the fuel pump may overheat, which may cause multiple concerns. The fuse for the pump may blow, which will prevent the vehicle from starting and running. A check engine light may come on from connector damage. Fuel may leak out of the connector body and create a fire hazard. Dealers will remove the fuel tank and remove the module reservoir assemblies from the fuel tank, and install a new service kit.
The hydraulic pump that controls power steering and in some cases hydro-boost power brakes may experience a fracture of its driveshaft. If this shaft breaks, power steering assist will cease immediately and hydro-boost brake power will also cease following depletion of stored reserve pressure. An increase in steering and brake effort may cause an accident. Dealers will replace the hydraulic pump.
