The 2006 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 inflator rupture issue is a well-documented defect in Takata-supplied airbag inflators. Over time, the propellant inside can degrade and cause the inflator to explode with excessive force rather than inflate the airbag in a controlled way. When that happens, pieces of the metal inflator housing can break apart and travel into the front seating area. This defect affects both the driver and passenger sides of the cabin.
The fourth recall is connected to a prior repair attempt that did not fully resolve the problem. Some FX45s that had already received a replacement front passenger airbag assembly under an earlier recall may have had the airbag cushion folded incorrectly during that service. An improperly folded cushion traps excess internal pressure during deployment, which can tear the cushion itself. A torn airbag does not inflate properly and offers less protection to the front passenger in a crash.
