Chevrolet Monte Carlo LS1998

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.

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

GENERAL MOTORS IS RECALLING 1,497,516 MY 1997-2003 BUICK REGAL, MY 1998-2003 CHEVROLET LUMINA, MONTE CARLO AND IMPALA, MY 1998-1999 OLDSMOBILE INTRIGUE, MY 1997-2003 PONTIAC GRAND PRIX VEHICLES EQUIPPED WITH A 3.8L V6 NATURALLY ASPIRATED ENGINE. SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH DROPS OF ENGINE OIL MAY BE DEPOSITED ON THE EXHAUST MANIFOLD THROUGH HARD BRAKING.

IF THE MANIFOLD IS HOT ENOUGH AND THE OIL RUNS BELOW THE HEAT SHIELD, IT MAY IGNITE INTO A SMALL FLAME AND MAY SPREAD TO THE PLASTIC SPARK PLUG WIRE CHANNEL AND BEYOND INCREASING THE RISK OF AN ENGINE COMPARTMENT FIRE.

CERTAIN PASSENGER VEHICLES HAVE LOWER PINION BEARINGS IN THE POWER RACK AND PINION ASSEMBLY IN WHICH THE RETAINER TABS WERE NOT CRIMPED PROPERLY. THESE RETAINERS COULD FAIL AND PERMIT THE BALL BEARINGS TO ESCAPE.

IF THIS OCCURS, THE PINION SHAFT CAN BE FORCED UPWARD DURING LEFT TURNS AND BACK DOWN AS THE STEERING WHEEL IS MOVED BACK AND TO THE RIGHT. IF THE PINION SHAFT MOVES FURTHER, THE DRIVER WILL NEED TO EXERT MORE EFFORT TO TURN THE STEERING WHEEL, SIMILAR TO A VEHICLE WITHOUT POWER ASSISTED STEERING. IF THE PINION SHAFT MOVES EVEN FURTHER, THE DRIVER WILL REQUIRE MUCH HIGHER EFFORT TO TURN LEFT AND MAY NOT BE ABLE TO TURN THE WHEEL AS MUCH AS INTENDED. WITH THE MAXIMUM PINION SHAFT MOVEMENT, WHICH REQUIRES INTERNAL GEAR COMPONENT DAMAGE, THE DRIVER CAN ENCOUNTER HIGH RESISTANCE TO TURNING LEFT, FOLLOWED BY UNINTENDED POWER ASSIST TO THE RIGHT. IN ANY OF THESE CONDITIONS, A CRASH COULD OCCUR.
