The steering wheel position sensor may fail, resulting in the service stability message being displayed.

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.

A clicking noise may be noted from the turn signal flasher after the turn signals are switched off.  This is commonly cause by a faulty turn signal switch which will require replacement.

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.

A rattling noise may develop from the AC belt tensioner. This can be caused by an internal fault with the AC compressor, AC performance may also be diminished when this occurs. Our technicians tell us that replacing the ac compressor will commonly correct this concern.
