If the key is turned to the "off" position without the transmission being in the "park" position, it is possible that the steering wheel can lock when turned to the right.
Certain sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard no. 114, "theft protection." During an inspection of some vehicles at the assembly plant, it was found that the steering wheel was locked with the ignition knob in the "off" position but the vehicle transmission not being in the "park" position.
Dealers will inspect and replace the steering wheel lock assembly free of charge. The recall began on December 18, 2006. Owners may contact Nissan at 1-800-647-7261.
