The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.
The crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.

The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
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.
