Known Problems

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

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

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

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

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

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

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

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 steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with your local GM dealer to find out what the latest repair is for this condition.

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

The display on the heater and AC control panel may become dim or go completely blank. Our technicians tell us the control panel must be replaced to correct this fault.

The upper intake manifold may develop an internal coolant leak causing one or more cylinders to fill with coolant. This can cause the engine to "hydro-lock" and not turn over. Removing the spark plugs will allow the engine to turn over pushing the coolant out of the spark plug holes. Replacing the upper intake plenum and gasket is commonly required to correct this condition.

The engine can be very difficult to start after this problem has been repaired, it can be helpful to clear as much of the coolant from the intake manifold and cylinders as possible before reassembling the intake manifold.

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.

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

Door lock mechanisms not operating properly. Doors may not lock/unlock.

Replacement of faulty door lock actuator required for proper operation.
