Nissan North America is recalling nearly 3.18 million vehicles in the U.S. because their front passenger air bags may not deploy properly during a crash.

The problem is tied to the occupant classification system, which might incorrectly classify an adult passenger as a child or classify the seat as empty when it's not. As a result, the passenger air bag may be mistakenly disabled, according to the National Highway Traffic Safety Administration.

The remedy will involve software reprogramming in some models, and hardware replacement in others. 

The vehicles involved in the recall are:

• 2015-2016 Chevrolet City Express (based on Nissan NV200 compact cargo van)

• 2013 Infiniti JX35

• 2014-2016 Infiniti Q50

• 2014-2016 Infiniti QX60

• 2013-2016 Nissan Altima

• 2013-2016 Nissan LEAF

• 2016-2017 Nissan Maxima

• 2015-2016 Nissan Murano

• 2013-2016 Nissan NV200

• 2014-2016 Nissan NV200 Taxi

• 2013-2017 Nissan Pathfinder

• 2014-2017 Nissan Rogue

• 2013-2016 Nissan Sentra.

Dealers will reprogram the air bag control unit and occupant classification system electronic control unit in Altima, Maxima, Murano, Rogue, and Sentra vehicles. The occupant classification system electronic control unit will be replaced in LEAF, NV200, NV200 Taxi, Pathfinder, Infiniti Q50, JX35, QX60 and Chevrolet City Express vehicles. There will be no charge for this service.

General Motors will notify the Chevrolet City Express vehicle owners.
