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.

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

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

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 ABS master cylinder assembly may fail internally causing the ABS light to illuminate.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

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 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.

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

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

The ABS brake pressure modulator valve can fail internally causing the ABS light to illuminate.

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.
