What stands out
Airbags accounts for 23% of all owner complaints filed against this vehicle, across 4 categories tracked.
No new NHTSA airbags complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
SERVICE INFORMATION Changes or modifications to the front seat assembly trim materials may affect the proper operation of the Front Seat-Mounted Side-Impact Supplemental Air Bags and Passenger Occupant Classification Sensor and could result in serious personal injury or death. Infiniti STRONGLY RECOMMENDS AGAINST making any change to seat trim materials from the factory equipped condition. This specifically applies to replacing the seat trim with non-factory materials; adding leather/cloth seat covers, seat pads, or seat storage pouches, etc. around or over the seat back and the passenger seat cushion. See this bulletin for further detail.

The failure pattern owners describe
The 2008 EX35 shows two distinct airbag problems. First is a widespread occupant classification sensor malfunction. Multiple owners report the passenger airbag warning light staying on constantly or illuminating randomly, even with an adult in the seat. Dealership diagnostics identify a communication fault between the ACU (Airbag Control Unit) and OCS (Occupant Classification Sensor) under the passenger seat. Repair costs run $1000 to $6400 depending on which component needs replacement. The frustration here centers on VIN-specific exclusions: three NHTSA recalls exist for this exact issue on 2007–2008 EX35s (campaign 08V521000), yet owners claim their VINs fall outside recall scope despite matching year, model, and symptoms. One owner replaced the OCS; the light returned six weeks later.
The second issue is more serious: two separate complaints describe airbag non-deployment during crashes. One involved a low-speed curb strike that somehow triggered deployment instead. The other two describe crashes where front airbags simply did not deploy—one a full frontal impact after collision with another vehicle, the other a passenger-side impact at 15 mph. Both vehicles were totaled; occupants were injured. Neither situation produced clear diagnostic information in the narratives.
Failure modes owners describe
Airbag warning light / ACU-OCS communication fault
Airbag warning light flashes or stays on continuously. Dealership diagnostics point to communication problems between the Airbag Control Unit (ACU) and Occupant Classification Sensor (OCS), located under the passenger seat. Owners report that replacement parts appear undamaged yet fail.
When: No specific mileage cited; occurs after normal use
Symptoms owners cite: Dashboard airbag warning light flashing or constant illumination; Passenger airbag status light indicates airbag off despite adult occupant in seat
Repairs/costs cited: ACU replacement $1000+; OCS replacement estimated $3200–$6400. One owner reset sensor after replacement; light returned after six weeks.
Recalls/TSBs owners mention: Three recalls exist for 2007–2008 EX35 ACU/OCS problems (NHTSA campaign 08V521000 referenced), but owners report their VINs excluded from coverage despite same model year and symptoms.
Airbag deployment on low-speed curb strike
Airbag deployed when vehicle struck a 4-foot concrete curb at parking garage gate while moving from stopped position. Owner reports zero bumper damage and minimal contact speed.
When: No mileage given
Symptoms owners cite: Airbag deployed unexpectedly on low-speed impact with curb; Occupant sustained lacerations to forehead and hands; black and blue eyes reported
Repairs/costs cited: Airbag replacement expensive; deployment damaged electrical system.
Recalls/TSBs owners mention: No response documented. Owner states airbag recall does not apply to their VIN.
Front airbag non-deployment in crash
Front airbags failed to deploy during full frontal impact. Vehicle struck by another car on driver side (all side airbags deployed), then collided head-on with brick column. Frontal impact was severe enough to total vehicle.
When: No mileage given
Symptoms owners cite: Front airbags did not deploy in frontal crash; Occupant sustained fractured vertebra and concussion
Airbag non-deployment in passenger-side impact
Airbags did not deploy when another vehicle ran red light and struck front passenger side of EX35 at approximately 15 mph. Vehicle destroyed in crash.
When: At approximately 115,000 miles
Symptoms owners cite: Airbags did not deploy in frontal passenger-side impact crash; Occupant sustained injury
Recalls/TSBs owners mention: Manufacturer not notified of failure.

Tl* the contact owns a 2008 Infiniti ex35. The contact stated that the air bag sensor illuminated, indicating that the air bags malfunctioned. The vehicle was not included in NHTSA campaign number:08v521000 (air bags, electrical system). The vehicle was taken to an authorized dealer who diagnosed that the front passenger side seat needed to be replaced. The vehicle was not repaired. The…
The dash board airbag warning light started flashing. It stayed flashing for a few weeks, so I took it to an Infiniti dealership. The dealership told me there was some type of communication problem between the acu and ocs units, located under the passenger seat. They said they couldn't tell any more than that, and would try replacing the acu first (this cost me over $1000). They then said if…
Airbag sensor in passenger side seat is not working , other 2008 ex35 recalled for this, but not mine!!!??? Dealer wants 4600 dollars to repair it!!

Takata recall
The passenger airbag light stays on constantly. We had the dealership do a diagnostic on it and came back that the occupant control sensor unit in the passenger seat is bad and they want 6400.00 to fix it!! Ironically, other 2007-2008 infinity ex35 models were recalled for the same issue, except mine due to my VIN! Why were 200,00+ other cars from same year and model recalled but not mine? Even…
The 2008 Infiniti ex35 was struck by a car (Honda accord) going through a red light. Initial contact on the driver side of the car - all side airbags deployed. The Infiniti then hit a brick column supporting a building with full frontal impact between the headlights. The front air bags did not deploy. The car was a complete loss - $26,000. The driver suffered a fractured vertebrae and…
The occupant classification sensor does not always function properly. Even with an adult passenger in the front passenger seat, using the seat belt, the passenger air bag status light occasionally is illuminated (indicating air bag is off). This appears to occur randomly. I cannot find a pattern on what causes this to happen. We first noticed it more than 2 years ago, but didn't think much…
