Nissan is calling back about a million of its 2013 and 2014 vehicles: Thanks to a software issue, the passenger airbag may not expand during an accident. The problem is related to the car not recognizing that there is a passenger in the seat, the Los Angeles Times explains. Affected models are the Altima, Sentra, Leaf, Pathfinder, and NV200, as well as the Infiniti JX35, Q50, and QX60. The company is aware of accidents but no fatalities tied to the issue. Some of the same batch of vehicles were recalled last year, also due to passenger air bag problems, USA Today notes. The news comes as GM and Toyota are embroiled in safety concerns of their own.
