2001 Infiniti QX4 4WD
Fuel Economy Overview
The 2001 Infiniti QX4 4WD achieves an EPA-estimated 15 MPG in combined city and highway driving, with 14 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 2001 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 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.
ON CERTAIN VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, IOWA, ILLINOIS, INDIANA, KENTUCKY, MASSACHUSETTS, MAINE, MARYLAND, MICHIGAN, MINNESOTA, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, TENNESSEE, VERMONT, VIRGINIA, WEST VIRGINIA , WISCONSIN AND THE DISTRICT OF COLUMBIA, DURING THE COATING PROCESS OF THE FUEL FILLER TUBE ASSEMBLY, AN INSUFFICIENT AMOUNT OF COATING MAY HAVE BEEN APPLIED AT THE LOWER MOUNTING BRACKET. THIS COULD RESULT IN AN OPENING IN THE COATING WHICH CAN ALLOW WATER TO ENTER AND MAKE CONTACT WITH THE BARE METAL OF THE TUBE.
Consequence & Remedy
Consequence: THIS MAY RESULT IN SURFACE RUST BUT NOT PERFORATION OF THE TUBE. HOWEVER, IN THOSE AREAS OF THE COUNTRY WHICH USE HEAVY CONCENTRATIONS OF ROAD SALT IN THE WINTER, IF A MIXTURE OF SNOW/WATER AND SALT MAKES CONTACT WITH THE BARE METAL, CORROSION MAY OCCUR TO A DEGREE WHICH RESULTS IN PERFORATION OF THE TUBE. IN THIS CASE FUEL LEAKAGE MAY OCCUR WHEN FILLING THE TANK. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL REPLACE THE FUEL FILLER TUBE ASSEMBLY WITH A NEW ONE WITH AN IMPROVED COATING PROCESS. THE RECALL BEGAN ON NOVEMBER 26, 2007. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES. SOME OF THE BRACKETS USED TO ATTACH THE TWO GAS STRUTS TO THE REAR DOOR (HATCH) MAY HAVE BEEN IMPROPERLY MADE. AT HIGH AMBIENT TEMPERATURES, THE INCREASE IN GAS PRESSURE IN THE STRUT(S) COULD CAUSE ONE OR BOTH BRACKETS TO BEND, RESULTING IN THE STRUTS DETACHING FROM THE BRACKET(S) WHEN OPENING OR CLOSING THE REAR DOOR.
Consequence & Remedy
Consequence: IF BOTH STRUTS DETACH FROM THE BRACKETS, THE DOOR WILL RAPIDLY FALL DOWN, POSSIBLY STRIKING SOMEONE AND CAUSING SERIOUS INJURY.
Remedy: DEALERS WILL REPLACE THE STRUT BRACKETS. OWNER NOTIFICATION BEGAN SEPTEMBER 24, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT NISSAN AT 1-800-647-7261.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THESE VEHICLES MAY HAVE AN IGNITION LOCK ASSEMBLY WITH IMPROPERLY SEATED KEY CYLINDER CAP CONNECTOR PINS. VIBRATION CAN CAUSE THE CONNECTING PINS TO LOOSEN AND/OR FALL OUT ALLOWING THE KEY CYLINDER CAP TO DISENGAGE FROM THE KEY CYLINDER.
Consequence & Remedy
Consequence: IF THIS OCCURS, THE STEERING WHEEL LOCK ROD CAN MOVE, WHICH COULD LOCK THE STEERING WHEEL, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE IGNITION LOCK ASSEMBLY AND ASSEMBLIES WITH LOOSE OR MISSING END CAP CONNECTOR PINS WILL BE REPLACED. A RING CLIP WILL BE INSTALLED ON ALL OTHERS TO PREVENT LOOSENING OF THE PINS.
