Known Problems

Even though the manufacturer does not call for regular servicing, our technicians recommend servicing the power steering fluid regularly.

In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.


Checking and adjusting the AC compressor clutch air gap can extend the service life of the AC compressor.

Very hard shifting may be noted after the transmission reaches operating temperature. Most commonly this occurs in the higher gears and reverse. Replacement of the transmission may be recommended to correct this concern.

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 15,000 to 30,000 miles. If the fluid is dark or burned then the transmission fluid should be changed.

Do not use air filters with oil-coated elements. They may cause premature failure of the mass air flow sensor; this is not covered under the warranty.

Due to age and possible damage during removal, it is recommended to replace  the spark plug boots when replacing the spark plugs,

An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.
