In the event that the airbag is activated excessive internal pressure may cause the inflator body to rupture and metal fragments may pass through the cushion material causing injury to the vehicle occupants and / or in worst cases a fatality. The concern is caused by moisture in the air getting past faulty seals and being absorbed by the pyrotechnic biscuits in the inflator. As a result it is more likely to occur sooner in areas of high humidity and high temperature difference.
Abhilfe: Recall the vehicles that are likely to be affected and replace the passenger front air bag module which includes the inflator.
