The 2009 Audi S4 has 2 recalls, both involving the front passenger airbag inflator, which can rupture or explode and send metal fragments into the cabin, causing serious injury or death.
Both recalls cover the same defect in the passenger-side frontal airbag inflator. In a crash where the airbag deploys, the inflator can fail violently, scattering sharp metal fragments toward the driver and passengers rather than providing protection.
