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 variable valve timing camshaft actuators may stick due to dirty engine oil or a faulty control solenoid. A sticking actuator may cause a rough idle and the Check Engine Light to illuminate. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern.

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

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

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

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.

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.

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

A fluid leak may develop from the transmission output shaft seal. This leak may cause the transmission mount to become oil soaked and require replacement of the mount along with the leak repair.
