On the 2014 Infiniti QX80, the driver's frontal airbag inflator on affected vehicles was manufactured with an incorrect internal part. In a crash severe enough to demand deployment, the wrong part can block the flow of propellant, which causes the inflator to over-pressurize and rupture. A ruptured inflator sprays metal fragments into the cabin at the driver, turning the safety device into the injury source. NHTSA campaign 14V668000 covers 2014 QX80 vehicles built June 18, 2013 to February 11, 2014 and 2013 QX56 built September 1, 2012 to April 26, 2013. The recall began December 1, 2014. This is a manufacturing defect specific to these builds and is separate from the Takata inflator campaigns.

Common Symptoms

  • No warning symptoms — the defect is latent until deployment
  • SRS warning light if an unrelated airbag fault is also present

How to Fix

Check the VIN against NHTSA or Infiniti immediately — this is a build-date-limited campaign and the consequence is inflator rupture, which puts it in the highest urgency tier regardless of the vehicle's age or mileage. The dealer replaces the front driver airbag inflator free of charge. Do not defer this one behind routine maintenance, and do not accept a used or salvage steering wheel assembly as a substitute repair. If the SRS warning light is on, that is a separate fault needing diagnosis and does not indicate whether this recall was performed.

On the 2014-2026 Infiniti QX80, on QX80 vehicles fitted with 22-inch wheels, the Gross Axle Weight Rating printed on the certification label is incorrect and higher than the true rating. An owner loading the vehicle to the posted number — a realistic scenario on a three-row SUV used for towing, hauling, or family road trips — can overload the axle and the tires without any indication of doing so, which puts the vehicle out of compliance with FMVSS 110, Tire Selection and Rims. NHTSA campaign 26V455000 covers 2014-2027 QX80 with 22-inch wheels alongside 2020-2026 Nissan Armada and 2011-2013 QX56. VINs became searchable on NHTSA.gov July 16, 2026, and interim owner letters were expected to mail August 21, 2026. This is a very recent campaign with the final remedy still pending.

Common Symptoms

  • No mechanical symptoms — the defect is an incorrect information label
  • Vehicle can be unknowingly overloaded when loaded to the posted rating

How to Fix

The remedy is a corrected certification label: dealers will install new labels and Infiniti will also mail replacement labels to owners. Because the final remedy is still being rolled out, the practical near-term action is to stop relying on the door-jamb GAWR figure when loading a 22-inch-wheel QX80. Load conservatively, weigh the vehicle at a public scale if you tow or haul near capacity, and confirm the load rating stamped on the tires themselves rather than trusting the label. Note that the earlier campaign 14V129000 addressed the same class of error on 2014 QX80s with 20-inch wheels, so a given vehicle's history may show a prior label correction that does not satisfy this one.

On the 2011-2017 Infiniti QX80 5.6L VK56VD V8, the 5.6L VK56VD engine can develop timing chain stretch, particularly when oil changes are neglected. The primary and secondary timing chains elongate over time, causing rough idle, reduced power, and potential engine damage if not addressed.

Common Symptoms

  • Rattling noise at cold start
  • Check engine light with timing codes
  • Rough idle
  • Reduced engine power

How to Fix

Replace the timing chain, tensioners, and guides as a complete kit. This is a labor-intensive repair requiring significant engine disassembly. Strict adherence to 5,000-mile oil change intervals helps prevent premature chain wear.

On the 2014-2015 Infiniti QX80 VK56VD, fuel pressure sensors were not sufficiently tightened during production. As the vehicle is driven, vibration and thermal cycling allow the under-torqued sensor to loosen further until fuel escapes past its seal. A fuel leak in the engine bay, next to hot exhaust components and ignition sources, is a vehicle fire risk. NHTSA campaign 14V683000 covers QX80 alongside 2012-2014 Nissan Juke, 2012-2013 M56 and QX56, and 2014-2015 Q70 V8 vehicles. The recall began January 25, 2015 and the remedy is simply re-torquing the sensors.

Common Symptoms

  • Fuel smell from the engine bay
  • Visible fuel wetness or staining around the fuel rail
  • Check engine light with fuel pressure or rail pressure codes
  • Hard starting or rough running from lost rail pressure

How to Fix

Have the dealer re-torque the fuel pressure sensors under recall 14V683000, free of charge — this is a quick job, not a parts replacement. Independent of the recall, treat any fuel smell from the engine bay on this vehicle as urgent rather than a curiosity: stop driving it, and do not idle it in an attached garage. Look for wetness or a varnish-like stain around the fuel rail and the sensor boss. If the sensor has been loose long enough to damage its seal, re-torquing alone will not stop the leak and the sensor and seal need replacing.

On the 2014-2022 Infiniti QX80, qX80 vehicles with the rear self-leveling air suspension develop a persistent rear sag that makes the truck look permanently loaded, and the failure usually cascades in a predictable order. The rubber air springs crack and leak with age, typically after five to seven years. The compressor then runs constantly trying to hold ride height, and running constantly is what burns it out — so an owner who ignores a slow sag ends up paying for the compressor as well as the springs. Separately and very commonly, the rear ride height sensor, which connects the frame to the lower control arm on the driver's side, fails when water infiltrates it and shorts, causing the system to command the wrong height or give up entirely. RepairPal puts height sensor replacement around $690-$719 and compressor replacement around $824-$858 before any air spring work.

Common Symptoms

  • Rear end sagging as though loaded when empty
  • Vehicle sits low on all four corners after sitting overnight
  • Air compressor running constantly or far more than normal
  • Suspension warning light or ride height fault message
  • Vehicle fails to raise or lower on command
  • Harsh or bottoming ride at the rear

How to Fix

Diagnose in the right order and you avoid paying twice. Listen for the compressor running far longer or more often than normal, which is the earliest sign and means the system is chasing a leak. Spray soapy water on the rear air springs and their fittings and look for bubbles. Have the height sensor checked with a scan tool that reads live ride height values before replacing it on suspicion, since a failed sensor and a leaking spring produce a similar sag. Replace leaking air springs promptly rather than nursing them — every day of a leak is compressor life burned. If the compressor has already failed, replace the leaking springs at the same time or the new compressor follows the old one. Owners keeping a high-mileage QX80 long term sometimes convert to a conventional coil setup, which eliminates the failure mode at the cost of the self-leveling function; that is a reasonable choice on a truck that never tows, and a poor one on a truck that does.
