Problem: General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V-118, 09V-116, and 15V-201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
Risk: Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
Fix: The remedy applied under recalls 08V-118, 09V-116, and 15V-201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engineÂs front valve cover and gasket. Vehicles that are covered by recalls 08V-118, 09V-116, or 15V-201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number.

Owners may contact Chevrolet customer service at 1-800-222-1020, Buick customer service at 1-800-521-7300, Oldsmobile customer service at 1-800-442-6537 and Pontiac customer service at 1-800-458-8006.
