The 2007 Infiniti FX45 has 4 recalls, all involving the front passenger airbag, with the most serious being a Takata inflator that can rupture and send metal fragments into the cabin, causing serious injury or death.
The three inflator recalls describe the same underlying defect and should be understood as one issue: the passenger-side frontal airbag inflator can explode rather than inflate normally, turning the inflator housing into a source of metal shrapnel directed at anyone in the front passenger seat. The fourth recall affects vehicles that previously had the passenger airbag assembly replaced as part of an earlier repair. In those cases, the replacement airbag cushion was folded incorrectly, which can cause it to tear during deployment and reduce the protection it provides to the passenger.
