Known Problems

The cooling fan clutch may fail causing excessive fan noise and/or the Check Engine Light to illuminate.

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.

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Electrical power may be lost to the interior of the vehicle due to a blown 125 amp fuse located at the under hood fuse box. This fuse can blow if jumper cables are connected incorrectly. Replacing the blown fuse will commonly correct this problem.

The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engine Light to illuminate. Replacement of the cylinder head may be required to correct this concern.

The CD player in the radio may fail. Our technicians tell us that the radio will need to be removed and sent out to a radio repair shop to correct this condition.

Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.
