GM IS RECALLING 79 MY 2009 CHEVROLET IMPALA VEHICLES. SOME OF THESE VEHICLES HAVE A PASSENGER-SIDE FRONT AIR BAG INFLATOR THAT COULD FRACTURE AT AN INFLATOR TUBE DURING A DEPLOYMENT. DURING A PASSENGER-SIDE AIR BAG DEPLOYMENT, PIECES OF THE INFLATOR TUBE COULD STRIKE AND INJURY VEHICLE OCCUPANTS AND THE AIR BAG CUSHION WOULD NOT INFLATE FULLY, REDUCING THE CAPABILITY OF THE BAG TO PROTECT THE PASSENGER.
