NISSAN issued a recall on the QX4 model

On certain vehicles, the two pins that connect the key cylinder cap to the key cylinder were incorrectly inserted during assembly. Over time, vibration may cause the connecting pins to loosen and/or fall out. This condition could cause the cylinder cap to disengage from the key cylinder, allowing the wheel lock rod to move which could lock the steering wheel. Correction: Ignition lock assemblies will be inspected and those with loose or missing end cap connector pins will be replaced. A ring clip will be installed on all others to prevent loosening of the pins.
