General Motors Corp. is recalling 1.5 million vehicles because of potential engine fires.

GM said there have been no reports of any fires or injuries.

Some of the recalled vehicles were no longer in production. The recall included the 1998-1999 Oldsmobile Intrigue, the 1997-2003 Pontiac Grand Prix, 1997-2003 Buick Regal, and the 1998-2003 Chevrolet Lumina, Monte Carlo and Impala.

It involved vehicles with a 3.8-liter V6 engine. The government said drops of oil could fall into the exhaust system and cause a fire in the engine.

GM spokesman Kerry Christopher said it was a precautionary measure for consumers.
