Known Problems

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

The mode and temperature door actuators may fail causing improper air flow or temperature output from the heating and AC (HVAC) system.

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

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.

The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

The intake manifold gasket may develop external engine oil and/or coolant leak. The intake manifold will need to be removed and the gasket replaced to correct this issue.

The water pump may develop a coolant leak resulting in an engine overheating condition.

 

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

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.

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

Our technicians recommend flushing the brake fluid every 60,000 miles.  Brake fluid that is dirty may cause problems in the brake system.

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