Known Problems

A Loose or worn gas cap may cause Check Engine Light to illuminate.

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.

Failure of the crankshaft position sensor, ignition control module, or PCM may cause the Check Engine Light to illuminate.

General Motors recommends that the spark plugs should be replaced every 100,000 miles. Our technicians highly recommend the spark plug wires be replaced at the same time.

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.

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 EGR tube may develop an engine vacuum leak causing the engine to run lean. The Check Engine Light may or may not illuminate.

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

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
The ABS brake pressure modulator valve can fail internally causing the ABS light to illuminate.

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 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.

The steering rack may fail causing a loss of power steering fluid as a result the steering may become hard to turn.

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