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.

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

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.

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


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 Engine Control Module (ECM) can fail causing stalling and various other engine & transmission drivability concerns.

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.

Do to a low or erratic voltage condition, the fuel gauge needle may "jump" around and become stuck on the back side of the "stop" below the "empty" indicator. This does not mean the gauge is broken. If the gauge cover is removed and the needle is gently moved back around to the correct side of the pin, the gauge will again function normally. When the needle is moved back to the correct position, the electrical problem that caused the needle to jump in the first place must be corrected or the needle may jump around again. The most common problems that cause this condition are a weak battery or corrosion on the battery cable ends.

The outer tie rod ends on the steering linkage may wear causing excessive free play in the steering and uneven tire wear. If the worn tie rod ends are replaced, the wheel alignment should be checked and adjusted as necessary.

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

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.

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

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 highly recommend that the engine coolant be replaced every 30,000 miles.
