2004 Chevrolet Impala 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.
