2013 Nissan Sentra Recalls
The occupant classification system may malfunction, resulting in the front passenger air bag not deploying when needed in an accident. Dealers will update the system software free of charge to resolve the concern.
The airbag system uses a sensor in the front passenger seat to detect if the seat is occupied by an adult. The affected vehicles are being recalled because this sensor, part of the occupant classification system (OCS), may incorrectly identify the passenger seat as empty when it is actually occupied by an adult. When the passenger seat is determined to be empty, the passenger airbag is disabled. Failure of the passenger airbag to properly deploy when necessary would increase the risk of injury to someone seated in the passenger seat in the event of an accident. Dealers will update the OCS software to correct this concern.
The occupant detection system may unintentionally shut down the passenger front air bag so that it will not deploy in an accident. Dealers will inspect the sensors of the occupant detection system and replace them as necessary free of charge to resolve the problem.
During the manufacturing process, some fuel tank assemblies were not sealed correctly. As a result, a small amount of fuel can leak when the tank is full. Fuel leaks increases the risk of a fire so Nissan dealers will replace the affected fuel tanks to correct this concern.
