On the 2005-2007 Infiniti G35, the wire harness linking the belt tension sensor to the occupant detection sensor control unit under the front passenger seat is subject to relative movement as the seat is adjusted and as occupants shift. Over time that movement wears and oxidizes the terminals, interrupting the signal. With the signal lost the system cannot confirm occupant status and the airbag may not deploy in a crash. NHTSA campaign 10V175000 covers 2005-2007 G35 sedans built March 29, 2004 through August 25, 2006 and G35 coupes built April 1, 2004 through May 30, 2007. The recall began July 12, 2010.

Common Symptoms

  • Airbag warning light that comes and goes with passenger seat movement
  • Passenger airbag status indicator behaving erratically
  • SRS light illuminated with occupant detection codes
  • Airbag light triggered by passenger shifting position

How to Fix

Have the dealer perform the repair under recall 10V175000 free of charge — this one is build-date limited, so confirm eligibility by VIN rather than model year alone. An airbag warning light that comes and goes as the passenger seat is slid fore and aft is the signature of this fault and distinguishes it from a failed OCS control unit, which tends to fail in a fixed state. Note that this campaign and 08V521000 cover different components on overlapping cars, so a G35 may need both.

On the 2007-2008 Infiniti G35, a varistor inside the Occupant Classification System control unit, which sits in the front passenger seat cushion, was manufactured out of specification. Under certain conditions it interrupts the signal between the OCS and the airbag control unit. The airbag control unit interprets the lost signal by suppressing the passenger frontal airbag, so it will not deploy in a crash even with an adult properly seated. NHTSA campaign 08V521000 covers 2007-2008 G35 sedans along with the 2008 G37 Coupe, EX35, and a group of Nissan models — 204,361 vehicles in total. The recall began November 4, 2008.

Common Symptoms

  • Passenger airbag status light reads OFF with an adult seated
  • Airbag status indicator flickers between ON and OFF
  • Airbag warning light illuminated on the cluster
  • Seat classified as empty while occupied

How to Fix

Have the dealer test the OCS-to-ACU signal with the special tool called for by recall 08V521000 and replace the passenger seat cushion containing the OCS hardware if it fails, free of charge. Watch the passenger airbag status indicator on the console: if it shows OFF with a normally seated adult, the system is suppressing the bag right now. Remove aftermarket seat covers and anything stored under the passenger seat before diagnosing, since both interfere with the sensor mat and produce the same indication. Never bypass or unplug the OCS to clear the warning light — that removes the crash logic in both directions.

On the 2003-2007 Infiniti G35, the electronic steering wheel lock mechanism can malfunction, preventing the car from starting or causing intermittent no-start conditions. The steering lock actuator motor fails internally, triggering a security fault.

This issue also affects: Infiniti G37, Nissan 370Z, Nissan Altima

Common Symptoms

  • Car will not start with key in ignition
  • Steering wheel will not unlock
  • Security light flashing on dashboard

How to Fix

Replace the steering lock actuator or have the dealer reprogram the BCM. Some owners bypass the lock mechanism entirely, though this may affect resale value. A TSB was issued for certain model years.

On the 2006-2008 Infiniti G35, the dashboard topper material breaks down under sustained sun and heat, going soft and tacky to the touch before developing shiny patches, cracks, and chipping — typically first around the defroster vents and the instrument binnacle. Beyond the cosmetic damage the degraded surface becomes reflective, throwing glare onto the windshield that can be severe enough to obscure the driver's forward view in low sun. The defect is well documented across 2006-2008 G35 and M35 and 2008-2009 G37 vehicles and was the subject of class-action litigation against Nissan. Notably, Nissan extended warranty coverage for melting dashboards on some vehicles but did not do so for these G35, M35, and G37 models, so most owners face this as an out-of-pocket repair.

Common Symptoms

  • Dashboard surface soft, tacky, or sticky to the touch
  • Shiny reflective patches causing windshield glare
  • Cracks and chipping around the defroster vents
  • Discoloration or bubbling of the dash top
  • Glare that obscures forward vision in low sun

How to Fix

Do not expect goodwill coverage, though it is worth one call to Infiniti Consumer Affairs with the VIN since dealer discretion has occasionally applied. Practical options in ascending cost: a fitted dash cover or carpet-style mat, which hides the surface and kills the glare for well under a hundred dollars and is what most owners settle on; a vinyl or leather re-wrap by an upholstery shop; or full dashboard replacement, which is expensive largely because the labor requires removing the steering column, HVAC ducting, and often the windshield. Avoid silicone-based interior protectants on a dash already going soft — they make the tackiness worse. A windshield sunshade whenever the car is parked slows further degradation on a dash that has not yet failed.

On the 2003-2007 Infiniti G35, the VQ35DE engine in the G35 is known to consume excessive oil, sometimes burning 1 quart every 1,000-2,000 miles. This is typically caused by worn valve stem seals and piston rings that allow oil to enter the combustion chamber.

This issue also affects: Infiniti FX35, Nissan 350Z, Nissan Altima

Common Symptoms

  • Blue/white smoke from exhaust on startup
  • Low oil level warnings between changes
  • Fouled spark plugs

How to Fix

Replace valve stem seals and inspect piston rings. In severe cases, a short block replacement may be necessary. Use manufacturer-recommended 5W-30 oil and monitor consumption between changes.

On the 2006-2007 Infiniti G35, certain G35 headlamp assemblies do not meet the vertical gradient and headlamp photometric value requirements of Federal Motor Vehicle Safety Standard 108. In practice the beam cutoff is poorly defined and light output falls outside the required pattern, so the roadway is inadequately lit and oncoming drivers may be glared. NHTSA campaign 06V394000 covers the defect, with the recall expected to begin on or about April 16, 2007. The remedy is replacement of the headlamp assemblies, not an aim adjustment.

Common Symptoms

  • Poor or uneven road illumination at night
  • Ill-defined or missing beam cutoff line
  • Oncoming drivers flashing high beams
  • Dark spots or hot spots in the beam pattern

How to Fix

Have the dealer replace the headlamp assemblies under recall 06V394000, free of charge. Do not accept a headlamp aim adjustment as the fix — the parts themselves are out of specification and re-aiming a non-compliant lamp cannot bring it into compliance. Separately, on a G35 of this age the far more common complaint is simply hazed and yellowed polycarbonate lenses scattering the beam, which is an unrelated wear issue: restore or replace the lens before concluding the assembly is defective. Retrofitting LED or HID bulbs into these halogen projectors makes the beam pattern worse, not better, and is a common owner mistake here.

On the 2003-2008 Infiniti G35, the sunroof tray is designed to collect water and route it through four drain tubes running down the A- and C-pillars. Debris packs the drain nipples at the corners of the tray, the tray overflows, and water spills into the headliner and down the pillars into the cabin. Owners find soaked front or rear floor carpet, water dripping from the headliner or map light area, and a persistent musty smell. Because the water tracks down the pillars it reaches wiring and body modules, which is why this shows up as electrical symptoms — including door lock actuators cycling on their own — rather than as an obvious leak. It is the single most common source of interior water intrusion on this chassis.

Common Symptoms

  • Wet or damp carpet in the footwells
  • Water dripping from the headliner or map light area
  • Persistent musty or mildew smell in the cabin
  • Door locks cycling on their own or intermittent electrical faults
  • Water stains on the A-pillar or C-pillar trim
  • Windows fogging that will not clear

How to Fix

Open the sunroof and locate the drain openings at the four corners of the tray. Clear them with low-pressure compressed air or a length of weed-trimmer line worked in gently — never a stiff wire or a drain snake, which punches through the tube and dumps water directly into the pillar, converting a clogged drain into a permanent leak. Pour a small amount of water into the tray and confirm it exits behind each wheel. Fix this before chasing any electrical gremlin on a car with damp carpet, and pull the carpet and padding up to dry them fully, since trapped moisture corrodes the connectors and modules under the seats and in the kick panels. A leak that persists with clear drains is usually a failed sunroof seal or a detached drain tube behind the pillar trim.
