The 2008 Audi A4 has 4 recalls, all involving the airbag system, with the most serious being a Takata passenger-side frontal airbag inflator that can rupture and send metal fragments into the cabin, risking serious injury or death.
The inflator recall covers vehicles across a wide range of registrations, with some filings focused on high-humidity states and territories where the defect is more likely to develop. Regardless of where the vehicle currently lives, the underlying risk is the same: the inflator can explode rather than inflate in a crash, scattering sharp metal debris toward occupants. Prior repair attempts have addressed this issue through multiple campaigns, so owners should confirm their specific vehicle has been remedied by checking its VIN. A separate airbag concern affects the airbag control unit, which can corrode internally and stop functioning. If that happens, the airbags may not deploy at all in a crash, removing a key layer of occupant protection.
