How to read a Infiniti QX4 VIN — every digit explained
Every Infiniti QX4 carries a unique 17-character VIN stamped at the factory. Each position is a code — together they spell out where, when and how your car was built. Here's exactly what every digit means.
- WMI (1–3) — country & manufacturer. 4T1 = Toyota, built in the USA.
- VDS (4–8) — model line, body style, engine & restraint system.
- Check digit (9) — a math check that proves the VIN is genuine.
- Model year (10) — the year it was built. H = 2017.
- Plant (11) — which factory assembled this QX4.
- Serial (12–17) — the unique sequential production number.
Model-year code (10th digit)
The 10th character is the model year. It cycles through letters and numbers, skipping I, O, Q, U, Z and 0 to avoid confusion:
Where to find your QX4 VIN
- Dashboard — driver's side, visible through the windshield from outside.
- Driver's door jamb — on the manufacturer sticker when you open the door.
- Paperwork — vehicle registration, title and insurance card.
- Engine bay & frame — stamped on the firewall or chassis on many models.

2003 Infiniti QX4 recalls 4
Air Bags:frontal:driver Side:inflator Module
What's wrong. 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.
Risk. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Fix. 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 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.
Risk. 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.
Fix. 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.
Air Bags
What's wrong. Nissan North America, Inc. (Nissan) is recalling certain model year 2001-2003 Nissan Maxima, 2002-2004 Pathfinder, 2002-2006 Sentra, 2002-2003 Infiniti QX4 and I35, 2003 FX35 and FX45, and 2001 I30 vehicles. Upon deployment of the passenger side frontal air bag, excessive internal pressure may cause the inflator to rupture.
Risk. In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
Fix. Nissan will notify owners, and dealers will replace the passenger air bag inflator, free of charge. The recall began on June 15, 2015. Owners may contact Nissan customer service at 1-800-647-7261. Note: On December 18, 2015 Nissan informed NHTSA of an amendment of this recall to remove 2004-2005 Infiniti FX35 and FX45 vehicles.

The vehicles are equipped with non-desiccated, frontal passenger air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Risk. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Fix. Nissan will notify owners, and dealers will replace the front passenger air bag inflators with alternate desiccated inflators, free of charge. The recall began February 12, 2020. Owners may contact Nissan customer service at 888-737-9511 or Infiniti customer service at 888-810-3715.

Air Bags:frontal
What's wrong. 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.
Risk. THE INFLATOR HOUSING MAY RUPTURE AND PIECES OF THE INFLATOR COULD STRIKE AND INJURE VEHICLE OCCUPANTS.
Fix. 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.

2000 Infiniti QX4 recalls 3
Electrical System:ignition
What's wrong. 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.
Risk. IF THIS OCCURS, THE STEERING WHEEL LOCK ROD CAN MOVE, WHICH COULD LOCK THE STEERING WHEEL, INCREASING THE RISK OF A CRASH.
Fix. 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.

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.
Risk. 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.
Fix. 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.

Can a Infiniti QX4 tow? Towing & payload
As an SUV, the Infiniti QX4 is built to tow and haul. The exact maximum towing capacity and payload depend on the engine, drivetrain and whether it has the factory tow package, on a curb weight near 4,352 lb.
What sets your QX4's tow & payload rating:
- Engine — a larger or turbocharged engine tows more than the base unit.
- Drivetrain & axle — 4WD/AWD and the axle ratio shift the rating.
- Tow package — the factory towing package (hitch, wiring, transmission cooler) raises the max.
- Payload & GVWR — GVWR caps the combined load; more passengers and cargo lower how much you can tow.
Exact towing capacity, payload and GVWR are added per engine, drivetrain and trim — decode your VIN above, or check the driver's door-jamb and hitch labels. Curb weight from vehicle specifications.
How much does a Infiniti QX4 cost to own?
A Infiniti QX4 tends to depreciate faster than average. A typical example keeps roughly 37% of its value after five years — losing about 63% to depreciation. Fuel, maintenance and insurance add to the total cost to own.
