Some of these engines may leak engine oil that could end up on the exhaust manifold during hard braking. If the manifold becomes hot enough, it could spark a small flame that could spread to the spark plug wire channel and lead to the risk of fire in the engine compartment.
Affected models include the 1997-2003 Buick Regal, 2000-03 Chevrolet Impala, 1998-99 Chevrolet Lumina, 1998-2003 Chevrolet Monte Carlo, 1998-99 Oldsmobile Intrigue and 1997-2003 Pontiac Grand Prix.
Dealers will remove the spark plug wire retention channel from the front engine bay and install two spark plug wire retainers free of charge.
