The 2009 Ford Mustang has 5 recalls, all centered on the same critical defect: frontal airbag inflators on both the driver and passenger sides can rupture during deployment, sending metal fragments into the cabin.
All five recalls trace back to the same underlying problem with Takata-supplied airbag inflators. On the driver's side, the dual-stage frontal airbag inflator can take on moisture over time, and when the airbag fires in a crash, that moisture causes the inflator to burst rather than inflate the bag cleanly. On the passenger side, the same type of rupture can occur, with jagged metal pieces traveling toward the driver and any front-seat occupants at the moment they most need the airbag to protect them. Several of these filings specifically apply to vehicles that were sold in or ever registered in high-humidity states and territories, including Florida, Hawaii, Texas, Louisiana, and others, because prolonged exposure to heat and moisture accelerates the inflator's degradation. The driver-side recall applies more broadly regardless of registration location. Prior repair attempts did not fully resolve the issue for all affected vehicles, which is why multiple separate campaigns exist for what is fundamentally the same defect. Any 2009 Mustang that has not had its airbag inflators replaced under one of these recalls remains at risk of serious injury to front occupants in a crash that triggers airbag deployment.
