The 2005 Audi A4 has 3 recalls, all centered on the front passenger airbag inflator, which can rupture and send metal fragments into the cabin, posing a serious risk of injury or death to occupants.
These three recalls cover the same underlying defect in the passenger-side frontal airbag inflator. When the airbag deploys, the inflator can burst apart rather than inflate the bag in a controlled way, scattering sharp metal fragments toward the driver and passengers. One filing is geographically scoped to vehicles originally sold or registered in high-humidity states and territories, including Florida, Texas, California, Hawaii, and several U.S. island territories, where heat and moisture accelerate the conditions that make the inflator unstable. The other filings cast a broader net across additional body styles, including the A4 Sedan, A4 Avant, S4 Sedan, S4 Avant, RS4, and Cabriolet variants. If prior repair attempts were made under an earlier version of this recall, it is worth confirming the remedy was fully completed, as some inflator replacements in this campaign were phased in over time.
