Chevrolet Monte Carlo ProblemsEngine Starts and Stalls Due to Secutiry System Fault
The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.
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.
Corrosion may develop at the connection between the ignition coil tower and spark plug wire resulting in an engine misfire. The Ignition coil and spark plug wire should both be replaced to correct this condition.

Chevrolet Monte Carlo RecallsEngine Oil Leaks Onto Exhaust Manifold
Engine oil can leak onto the exhaust manifold, causing a fire hazard. This concern was addressed in previous recall notifications, but improvements to the repair have been made. Dealers will make improved repairs free of charge to resolve the concern.
Engine oil may leak from the valve cover area, which can cause a burning odor and increase risk of fire. Dealers will replace the spark plug wire retainer to redirect the dripping oil on affected vehicles, and will replace the left valve cover gasket on vehicles with the 3.8L V6 supercharged engine.
Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will provide two replacement key rings and key cover on all ignition keys to correct this concern.
