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.

Consequence: Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.

Remedy: 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 engine’s 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. The recall began on February 19, 2016. 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. GM's number for this recall is 15757. Note: Until the improved remedy has been applied, owners are advised to park their vehicle outside since the fire risk exists even when the vehicle is unattended.

ON CERTAIN PASSENGER, SPORT UTILITY VEHICLES AND MINI VANS, SOME OF THESE VEHICLES HAVE A PASSENGER AIR BAG THAT WAS MANUFACTURED WITHOUT A CHECK VALVE PIN. AN AIR BAG WITHOUT THE CHECK VALVE PIN COULD PRODUCE INCREASED PRESSURE AT THE ONSET OF THE AIR BAG DEPLOYMENT AND REDUCED PRESSURE AFTERWARD.

Consequence: THIS COULD INCREASE THE SEVERITY OF INJURY TO A PERSON WHO WAS NOT PROPERLY RESTRAINED AND WHO WAS CLOSE TO THE PASSENGER AIR BAG AT THE TIME OF DEPLOYMENT. IT COULD ALSO REDUCE THE AB8ILITY OF THE AIR BAG TO PROTECT A RESTRAINED FRONT SEAT PASSENGER.

Remedy: DEALERS WILL INSPECT AND, IF NECESSARY, REPLACE THE PASSENGER AIR BAG. OWNER NOTIFICATION BEGAN DECEMBER 16, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020, PONTIAC AT 1-800-762-2737, OLDSMOBILE AT 1-800-442-6537, OR SATURN AT 1-800-553-6000, PROMPT #3.
