The 2000 Infiniti QX4 has 3 recalls, the most serious being a faulty ignition lock assembly where vibration can loosen internal pins and cause the steering wheel to lock up while driving.
The same ignition defect was filed across two separate recall actions, but both describe the same risk: the key cylinder cap comes loose, the steering lock rod shifts, and the wheel can lock without warning. There is also a suspension concern affecting vehicles registered in certain northern and midwestern states prone to road salt and corrosion: the front strut housing can crack and pull away from the inner hood ledge assembly, compromising the front suspension's attachment to the vehicle structure.
