2001 Infiniti QX4 Problems
The 4WD light may flash on and off intermittently with no transfer case related fault code stored in the powertrain control module (PCM). Our technicians recommend to ensure the correct Nissan/Infinity approved fluid is present in the transfer case if this condition occurs.
The heater blower motor may only work on the high speed setting. Our technicians recommend replacing the heater blower motor and fan control amplifier to address this problem.
The Check Engine Light may illuminate with code P0138, P0140, P0158, and/or P0160 stored. Our technicians recommend replacing the rear oxygen sensor, and reprogramming the vehicle's powertrain control module (PCM) with upgraded software to correct this concern.

2001 Infiniti QX4 Recalls
In areas where winter road salt is used, a mixture of snow/water and salt may enter an assembly location hole in the upper strut housing. This corrosive mixture can collect on the mating surface of the strut housing panel and the inner hood ledge assembly; over time, this can cause rusting of the strut tower housing. The rust can weaken the housing, causing it to crack and pull away from the inner hood ledge assembly. This can lead to grinding noises and increased steering effort, which, if severe enough, can cause the steering column to break. This would result in a loss of steering control, increasing the risk of a crash. Dealers will inspect the strut housing and repair the vehicles as necessary. An interim notification letter should be mailed to owners prior to May 16, 2011.
