Known Problems

An internal distributor fault could cause the Check Engine Light to illuminate, an engine misfire, or a stalling condition. Replacement of the distributor is commonly recommend to correct this concern.

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 30,000 miles and the spark plug boots should be checked for hot spots and cracks.

The transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.

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

Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

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

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

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.

The idler arm or pitman arm in the front suspension may wear causing excess play in the steering and front end alignment problems.
The EGR valve or control solenoid may fail causing the check engine (SES) light to illuminate.

The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.
