The 2003 Infiniti QX4 has 3 recalls, the most serious being a Takata airbag defect where the passenger-side frontal airbag inflator can rupture and send metal fragments into the cabin, potentially causing serious injury or death.
The airbag issue has been the subject of multiple recall filings, and prior repair attempts may not have fully resolved the problem for all affected vehicles, so it is worth confirming your VIN has been remedied. There is also a suspension concern affecting vehicles registered in certain northern and midwestern states: the front strut housing can crack and pull away from the inner hood ledge assembly, which compromises the structural connection between the front suspension and the body and can affect handling and steering stability.
