Defect
THREADED INFLATOR COMPONENTS MAY HAVE BEEN DAMAGED DURING ASSEMBLY WHICH MAY ALLOW COMPONENTS TO SEPARATE WHEN INFLATOR RECEIVES A SIGNAL TO DEPLOY THE AIR BAG.
Consequence
INFLATOR COMPONENT SEPARATION ALLOWS HOT COMBUSTION GASES TO ESCAPE INTO THE PASSENGER COMPARTMENT WHICH COULD RESULT IN INJURIES TO VEHICLE OCCUPANTS.
Remedy
REPLACE AIR BAG MODULES CONTAINING POTENTIALLY DEFECTIVE INFLATORS.
