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 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.

I have an immaculately maintained 2018 Infiniti Q70L, but the OCS system began having issues at under 75k miles. Originally, the problem was the passenger seat sensor not detecting someone in the seat, so airbags were disabled. This occured sporadically for a year, but no codes were detectable by dealership. Now the airbag sensor light flashes continually, which began happening a few weeks ago. The dealership has now informed me that the OCS system has internal faults and the entire system must be replaced at a price of nearly $10K. Other years of Infiniti vehicles have already been recalled for the same issues with airbags and sensors, yet the problem persists. Message boards are full of Infiniti owners dealing with this same issue on their vehicles that are also excluded from the recall. This is a known safety issue, and a major defect in manufacturing, due to no fault of the owners of the vehicles. THIS NEEDS TO BE A RECALL.
