2002 Infiniti QX4 4WD
Fuel Economy Overview
The 2002 Infiniti QX4 4WD achieves an EPA-estimated 15 MPG in combined city and highway driving, with 13 MPG in the city and 17 MPG on the highway. Powered by a 3.5L 6-cylinder engine paired with a automatic 4-spd, this sport utility vehicle - 4wd features 4-Wheel or All-Wheel Drive drive.
In terms of environmental impact, the 2002 QX4 4WD produces approximately 592 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this QX4 4WD has higher-than-average emissions in this regard.
The estimated annual fuel cost for this vehicle is $4,000, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $9,250 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Personalized Commute CalculatorEPA defaults to 55% City / 45% Hwy
Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
The Brick Effect: Highway Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Because the Sport Utility Vehicle - 4WD has a large frontal area, expect your real-world highway fuel economy to drop by up to 25% at high speeds.

Recall Intelligence
Nissan North America, Inc. (Nissan) is recalling certain air bag inflator replacement service parts that may have been installed as part of a theft or collision repair. The parts include certain passenger-side air bag inflators designed to fit Infiniti 2002-2003 QX4, 2006-2010 M35 and M45; Nissan 2001-2003 Maxima, 2002-2006 Sentra, and both driver and passenger-side inflators designed to fit 2007-2012 Versa Sedan and Versa Hatchback vehicles. Please see Nissan's recall report for the specific part numbers. These replacement inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.
Consequence & Remedy
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Dealers will inspect and replace the inflators as necessary, free of charge. Owner notification letters are expected to be mailed September 14, 2022. Owners may contact Nissan's customer service at 1-800-867-7669.

Nissan North America, Inc. (Nissan) is recalling certain 2002 Pathfinder and Infiniti QX4 vehicles. These vehicles are equipped with Takata air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture.
Consequence & Remedy
Consequence: An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.
Remedy: Nissan will notify owners, and dealers will replace the front passenger air bag assembly, free of charge. The recall began on March, 31, 2017. Owners may contact Nissan customer service at 1-800-647-7261.

NISSAN IS RECALLING CERTAIN MODEL YEAR 1996-2004 PATHFINDER AND MODEL YEAR 1997-2003 INFINITI QX4 VEHICLES ORIGINALLY SOLD, OR CURRENTLY REGISTERED IN, CONNECTICUT, DELAWARE, IOWA, ILLINOIS, INDIANA, MASSACHUSETTS, MAINE, MARYLAND, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WASHINGTON D.C., WEST VIRGINIA AND WISCONSIN. IN AREAS OF THE COUNTRY IN WHICH HEAVY CONCENTRATIONS OF ROAD SALT ARE USED, A MIXTURE OF SNOW/WATER AND SALT MAY ENTER AN ASSEMBLY LOCATION HOLE IN THE UPPER STRUT HOUSING, CAUSING WATER TO COLLECT AT THE MATING SURFACE OF THE STRUT HOUSING PANEL AND THE INNER HOOD LEDGE ASSEMBLY. OVER TIME, THIS SNOW/WATER AND SALT INTRUSION MAY RESULT IN CORROSION OF THE STRUT TOWER HOUSING IN SOME SUBJECT VEHICLES.
Consequence & Remedy
Consequence: THE STRUT HOUSING MAY CRACK AND PULL AWAY FROM THE INNER HOOD LEDGE ASSEMBLY. THIS MAY LEAD TO GRINDING NOISES, INCREASED STEERING EFFORT, AND POSSIBLY THE STEERING COLUMN TO BREAK, RESULTING IN THE LOSS OF STEERING CONTROL, WHICH COULD RESULT IN A CRASH.
Remedy: NISSAN WILL INSPECT THE STRUT HOUSING AND REPAIR THE VEHICLES AS NECESSARY, FREE OF CHARGE. AN INTERIM NOTIFICATION LETTER WAS SENT OUT IN MAY 2011. THE SECOND NOTICE WAS MAILED ON JULY 25, 2011. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
NISSAN IS RECALLING FORTY-SIX CERTAIN MODEL YEAR 2002 PATHFINDER AND INFINITI QX4 VEHICLES MANUFACTURED FROM AUGUST 24, 2001 THROUGH AUGUST 28, 2001. THE AIR BAG INFLATOR CONTAINS PROPELLANT WAFERS THAT ARE REQUIRED TO PROPERLY DEPLOY THE FRONT PASSENGER AIR BAG. DUE TO IMPROPER PROPELLANT WAFER INSTALLATION DURING THE AIR BAG INFLATOR ASSEMBLY PROCESS, SOME AIR BAG INFLATORS MAY BE MISSING ONE OF THE WAFERS. AS A RESULT, THE REMAINING WAFERS IN THE INFLATOR USED FOR THE DEPLOYMENT OF THE FRONT PASSENGER AIR BAG MAY, OVER TIME, BREAK UP INTO POWDER DUE TO NORMAL VIBRATION EXPERIENCED WHILE DRIVING. THIS CAUSES THE COMBUSTION RATE OF THE PROPELLANT TO INCREASE INSIDE THE INFLATOR, WHICH CAN LEAD TO INTERNAL PRESSURE RISING SUDDENLY DURING AIR BAG DEPLOYMENT.
Consequence & Remedy
Consequence: THE INFLATOR HOUSING MAY RUPTURE AND PIECES OF THE INFLATOR COULD STRIKE AND INJURE VEHICLE OCCUPANTS.
Remedy: NISSAN WILL NOTIFY THE OWNERS OF THE FORTY-SIX AFFECTED VEHICLES. DEALERS WILL REPLACE THE FRONT PASSENGER AIR BAG MODULE ASSEMBLY WITH A NEW ONE FREE OF CHARGE. THE SAFETY RECALL BEGAN ON AUGUST 19, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261 AND INFINITI AT 1-800-662-6200.
