The recall affects the Altima, Leaf, Pathfinder and Sentra models from the 2013 and 2014 model years, as well as the NV200 Taxi van and Infiniti JX35 SUV from 2013. Also covered is the Infiniti QX50 SUV from 2014.
The company tells the National Highway Traffic Safety Administration that the vehicles' computer software may not detect an adult in the passenger seat. If that happens, the air bags won't inflate.
Nissan will notify owners and dealers will update the software for free. The recall is expected to start in mid-April.
