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.
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.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
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.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
