NHTSA Complaint #11711445 — 2008 BMW 328I

The vehicle’s "Passenger Airbag Off" light and dashboard SRS warning lamp are illuminated. A diagnostic scan using a BMW-specific tool confirms manufacturer Fault Code 93C3 (Passenger Seat Occupancy Detector). This indicates a hardware failure of the OC3 internal seat sensor mat. Safety Risk: The failure of this sensor prevents the vehicle from correctly identifying if an adult is in the passenger seat. This compromises the Supplemental Restraint System (SRS) and may result in the passenger airbag failing to deploy during a collision, posing a significant risk of injury or death to the occupant. Confirmation of Problem: The fault was confirmed via a digital diagnostic system (Foxwell NT510) which identified the specific "Open Circuit" within the seat mat. The component is currently installed in the vehicle and is available for inspection. Connection to Existing Recalls: This failure is identical in symptoms and fault code to those described in NHTSA Safety Recall 17V-428. Although this vehicle is the same year and model (2008 BMW 3-Series) as those covered in the recall, the VIN was excluded from the initial recall range. This appears to be a recall omission of a known manufacturing defect, as the failure occurred despite minimal use of the passenger seat.
