Nissan has recalled five 2013 car models due to air bag concerns. These models include the Altima, Sentra, Pathfinder and Leaf along with the Infinity JX35.
Sensors that detect weather or not a passenger is sitting in a seat may not be working properly. If a crash happens and no passenger is detected the airbag may not deploy.  Nissan discovered the problem because of warranty claims and bag warning lights that illuminated in cars at one of Nissans production plants in Tennessee.
The number of vehicles that might be in need of a recall has not yet been determined. Owners will be notified within the next month and, if necessary, dealers will inspect and replace the sensors.
