Known Problems

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

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

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 fuel pump may fail causing the engine to stall and not restart.

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
Our technicians recommend to replace the fuel system filter every 30,000 miles.

The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.

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

The crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.

The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.

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

The EGR tube may develop an engine vacuum leak causing the check engine (SES) light to illuminate.
Vehicles with the optional CRT dash may have the display fail. Our technicians tell us that the CRT unit will need to be sent out to a specialized repair facility for repair.
