The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.
On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

This vehicle has a thermostat that fails in the open position which causes the temp gauge to drop below normal and heater to fail. The thermostat is located on the driver's side of the engine behind the alternator. You might need to remove the wheel to access the mounting bolts. You will need multiple rachet extensions and some patience. Dealer wants $500 to replace thermostat. Do it yourself for less than $100.
