Reports submitted to NHTSA, shown in the owner's own words
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.

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.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
STRUCTURE:BODY
CERTIFICATION LABEL AND VIN PLATE REPLACEMENT SERVICE INFORMATION Because of collision damage or other vehicle repair, a replacement “Certification Label” or “VIN Plate/Label” may be needed. HINT: Certification Label = FMVSS (Federal Motor Vehicle Safety Standards) label. These items may be available from Infiniti by request if certain criteria are met. This bulletin lists the criteria and provides an application form for such replacements. · The “VIN Plate/Label” (metal plate or vinyl label) is attached to the instrument panel or body on the driver side at the base of the windshield (see Figure 1). · The “Certification Label” (vinyl adhesive label) is located on the lower area of the driver side B-Pillar (see Figure 1).

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
