On certain vehicles, the front passenger seat occupant detection mat can fatigue over time. As a result, the passenger airbag could deactivate, illuminating the airbag warning lamp and the passenger airbag ON/OFF lamp. Failure of the passenger airbag to deploy during a crash (where deployment is warranted) could increase the risk of personal injury to the seat occupant. Correction: Dealers will replace the occupant detection mat. Note: This recall is an expansion of recalls 2008-307 and 2013-238.
