GM IS RECALLING 207,542 MY 1997-2003 BUICK REGAL AND PONTIAC GRAND PRIX VEHICLES EQUIPPED WITH A 3.8L SUPERCHARGED V-6 ENGINE. THESE VEHICLES HAVE HIGHER FRONT ROCKER COVER GASKET TEMPERATURES, CREATING THE POTENTIAL FOR EARLIER DEGRADATION OF THE FRONT ROCKER COVER GASKET AND EVENTUAL OIL SEEPAGE.
ON CERTAIN PASSENGER VEHICLES AND MINI VANS, THE DRIVER'S AIR BAG INFLATOR MODULES COULD PRODUCE EXCESSIVE INTERNAL PRESSURE. IN THE EVENT OF A CRASH THAT WOULD TRIGGER A DRIVER'S AIR BAG DEPLOYMENT, THE INCREASED INTERNAL PRESSURE CAN CAUSE THE INFLATOR MODULE TO EXPLODE.
