Known Problems

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

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.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

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.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

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.

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 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.

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

The high pressure power steering hose will commonly leak fluid; it should be replaced.
