Infiniti QX4 ProblemsThe 4WD Light May Flash On and Off Intermittently
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/Infiniti approved fluid is present in the transfer case if this condition occurs.
Failure of the EVAP System charcoal canister may allow charcoal debris to infiltrate the EVAP system causing other failures. Cleaning the vapor lines to ensure the system is clear of debris is important when repairing EVAP system failures.
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.

Infiniti QX4 RecallsFront Airbag Inflator Module
This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Honda dealers will replace the affected airbag inflator modules to correct this concern.
Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.
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.
