The 2003 Infiniti QX4 has 3 recalls, the most serious being a passenger-side airbag inflator that can rupture during deployment and send metal fragments into the cabin, potentially causing serious injury or death.
The airbag concern covers both front passenger inflators and reflects the well-known Takata inflator defect, where excessive internal pressure causes the inflator housing to burst rather than simply inflate the bag. Any occupant in the front passenger seat faces exposure to metal shrapnel in a crash that triggers the airbag. Prior repair attempts for this issue may not have fully resolved it for all affected vehicles, which is why multiple filings exist for the same underlying problem.
The third recall affects vehicles registered in certain northern and mid-Atlantic states where road salt and moisture accelerate corrosion. The front strut housing can crack and pull away from the inner hood ledge assembly, which means the front suspension loses its anchor point. If this separation progresses, the driver can experience sudden and unpredictable changes in steering and handling, particularly during turns or over uneven pavement.
