Audi A4 RecallsDriver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments
The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag inflator free of charge to resolve the concern.
