The 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.

The Heater Blower Motor May Only Work on the High Speed Setting

2002 Infiniti QX4 Recalls

Passenger Air Bag Inflator Ruptures During Deployment Spraying Metal Fragments

The passenger frontal air bag inflator may rupture on deployment, causing metal fragments to come through the air bag and injure occupants. Dealers will replace the passenger frontal air bag assembly free of charge to resolve the concern.

Front 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.

Injury Due to Airbag Deployment

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.

I love my infiniti qx4 2002. This is my second one! It is quite expensive to maintain but it's worth the expense. Presently it's been diagnosed with po420 catalytic converter heart is sad....but still love my baby. Wish they did not discontinue the model. It is a very durable vehicle. I once saw 450,000 mileage accrued from QX4 4WD. It was still running, I fell in love....
The problems began in early 2012, when we signed up for a new “Express Service and Oil Change” program at our local dealer. We thought that this new offering, given that it allowed us to obtain service without an appointment, would make life easier. Instead, it has caused us untold hours of lost time, and consistent struggles to get Infiniti to deliver the level of service we had come to expect...
