The issue Toyota wants to inspect is a cable that can potentially become damaged as the passenger seat is adjusted fore and aft. The cable is part of the system that senses whether someone is sitting in the front passenger seat, thus enabling airbag deployment and seat belt pre-tensioning in the event of an accident.
Toyota says no crashes or injuries have resulted from this issue. The recall affects some 2012 and 2013 models.
Owners affected should look for a letter from Toyota detailing the issue.
