NISSAN issued a recall on the Q50 model

On certain vehicles, the front passenger seat occupant classification system software may incorrectly classify the passenger seat as empty, when it is occupied by an adult. If this occurs, the passenger airbag would be deactivated without the illumination of the airbag warning lamp. Failure of the passenger airbag to deploy during a crash (where deployment is warranted) could increase the risk of injury to the seat occupant. Correction: Dealers will reprogram the occupant classification system. This is an expansion of recall 2014-093.
