Known Problems

An ignition coil may fail causing one of the cylinders to misfire. Each of the two banks of cylinders has its own coil assembly. If one ignition coil fails the coil assembly for the corresponding cylinder bank must be replaced.

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.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

The EGR valve may stick open, causing a rough idle and/or the Check Engine Light to illuminate.

The crankshaft position sensor may fail causing the engine to stall intermittently, the Check Engine Light may or may not illuminate.

Failure of the catalytic converter can result in illumination of the Check Engine Light.

The Check Engine Light may illuminate due to an engine vacuum leak from the intake manifold area.

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

An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

One or more of the power window regulators (one in each door) may fail causing the window to fall into the door and not roll up.

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
