The NHTSA has commenced an "engineering analysis" of GM's supercharged 3800 Series II V6 engine. Fitted to certain 1999-2002 models, such as the Pontiac Grand Prix GTP, Buick Park Avenue, and Oldsmobile LSS, they are apparently catching fire at a rate thirteen times greater than the naturally aspirated engine. Specifically, the agency has 180 complaints of "non-crash-related fires originating in the engine compartment while driving or after the vehicle is parked and the ignition switched off." An engineering analysis isn't a recall, it is a possible precursor to a recall. If you have that particular engine in your ride, you can find out more about the NHTSA's investigation here.
