Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Component/system failed: Passenger seat occupant classification/seat weight sensor associated with the Supplemental Restraint System (SRS). Repair facility stated moisture or prior moisture intrusion likely affected the sensor. The failed component should be available for inspection upon request. Safety risk: The airbag/SRS system may not properly detect or classify a passenger, which could affect passenger airbag operation and occupant protection during a crash. The airbag warning light remained illuminated. Problem reproduced or confirmed: Yes. The issue was diagnosed and confirmed by the repair facility/dealer. Inspected by manufacturer, insurance, or others: The vehicle was inspected by a repair facility/dealer service department. Warning lamps/messages/symptoms: The airbag/SRS warning light illuminated. The repair facility identified the passenger seat weight sensor as the likely cause and noted prior moisture exposure affecting the sensor.

NHTSA ID 11736425 · filed May 7, 2026

The Passenger Occupant Classification System in the passenger seat is showing an airbag code of B00A0-02 on my 2018 Infiniti Q70L . The dealer cannot clear that code. The only solution is to replace the entire seat bottom (leather/foam/all electronics for raising the seat) all integrated. That part number is 87300-6ar3a and sells for $2800 plus labor to replace, over $600. My 2018 Infiniti Q70L only has 10300 Miles, garage kept. This integrated design has been problematic for the Q70 and Q50. Cost to repair is enormous. Infiniti should acknowledge this issue. It is a MAJOR SAFETY ISSUE, because if not repaired the passenger airbag is permanently turned off and for a failure for a car with so few miles and meticulously kept, this is unacceptable. I have 2 of the Q70's and its a matter of time before the other vehicle show the same issue.
