General Motors will be asking approximately 1.4 million vehicle owners to return to their dealerships to fix a problem affecting several older model nameplates. U.S. safety regulators issued a recall to fix the defect in 2007 after owners reported engine fires shortly after parking their vehicles. A second recall was issued in 2009 when over one thousand cars caught fire despite already being repaired.

GM is still working on a fix for the most recent recall, but according to reports the problem is caused by the valve cover gasket degrading over time and leaking. During braking, oil can drip onto the exhaust manifold and potentially catch fire. The recall affects certain 1997-2004 Pontiac Grand Prix, Buick Regal, Chevrolet Impala, Chevrolet Lumina, Chevrolet Monte Carlo, and Oldsmobile Intrigue equipped with 3.8L V6 engines.

GM says it has reports of 19 minor injuries in fires caused by the cars and advise owners to not park indoors until the defect can be repaired.
