The airbag system uses a sensor in the front passenger seat to detect if the seat is occupied by an adult. The affected vehicles are being recalled because this sensor, part of the occupant classification system (OCS), may incorrectly identify the passenger seat as empty when it is actually occupied by an adult. When the passenger seat is determined to be empty, the passenger airbag is disabled. Failure of the passenger airbag to properly deploy when necessary would increase the risk of injury to someone seated in the passenger seat in the event of an accident. Dealers will update the OCS software to correct this concern.
