GM recalling 1.4 million passenger cars over potential engine fires

The National Highway Traffic Safety Administration has just announced a major recall covering nearly 1.5 million General Motors passenger cars from the late 90's and early 2000s. The recall affects various Buick, Chevrolet, Oldsmobile, and Pontiac models equipped with normally aspirated versions of GM's much-utilized 3800 3.8-liter V6.

Apparently, some of these engines can drop oil onto the exhaust manifold during hard braking. If that manifold has gotten hot enough and the oil dribbles below the heat shield, it can start a small fire. The flames can then engulf the plastic spark plug wire channel, potentially resulting in a full-on engine compartment fire.

The fix? Dealer service departments will be asked to remove said spark plug wire retention channel from the front of the engine bay, and then retrofit two new retainers.

Models Affected:

1997-2003 Buick Regal
2000-2003 Chevrolet Impala
1998-1999 Chevrolet Lumina
1998-2003 Chevrolet Monte Carlo
1998-1999 Oldsmobile Intrigue
1997-2003 Pontiac Grand Prix

The recall is slated to begin in May. Official NHTSA Release after the jump.
