Known Problems

Problems with the 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 the key and ignition lock cylinder must be replaced to correct this 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.

Vehicles with certain V6 engines may illuminate the Check Engine Light one or more of the following codes: P0011, P0014, P0021, P0024, P0341, P0346, P0336, or P0391. Our technicians tell us that some vehicles may require a powertrain control module (PCM) software update to correct this issue. Other vehicles may have excess camshaft end play on one or both cylinder heads which will need to be corrected using special procedures outlined by GM.

The AC may stop working due to a refrigerant leak from the condenser. GM has developed and updated condenser and mounting bracket to help prevent the replacement condenser from failing in the same manner.

The CD player in the radio may fail. Our technicians tell us that the radio will need to be removed and sent out to a radio repair shop to correct this condition.

The steering wheel position sensor may fail, resulting in the service stability message being displayed.

An ignition coil may fail causing one of the cylinders to misfire. Each of the two banks of cylinders has its own coil assembly. If one ignition coil fails the coil assembly for the corresponding cylinder bank must be replaced.

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 mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

Illumination of the Check Engine Light may be the result of a loose or worn gas cap.

The high pressure power steering hose will commonly leak fluid and should be replaced if this is the case.

The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.

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