Nissan is recalling approximately 989,701 model year 2013-2014 Altima, LEAF, Pathfinder, and Sentra, model year 2013 NV200 (aka Taxi) and Infiniti JX35 and model year 2014 Infiniti Q50 and QX60 vehicles. There are 29,165 LEAFs involved in the recall.

In the affected vehicles, the occupant classification system (OCS) software may incorrectly classify the passenger seat as empty, when it is occupied by an adult.

If the OCS does not detect an adult occupant in the passenger seat, the passenger airbag would be deactivated. Failure of the passenger airbag to deploy during a crash (where deployment is warranted) could increase the risk of injury to the passenger.

Nissan will notify owners, and dealers will update the OCS software, free of charge. The recall is expected to begin in mid-April 2014.
