Nissan said the recall involves G35 Coupes from the 2005 to 2007 model years and G35 Sedans from the 2005 to 2006 model year.
The automaker says the air bag unit's wire harness under the front passenger seat could wear down and interrupt the air bag's signal. In a crash, the air bag may not deploy and could increase the risk of an injury.
Nissan spokesman Colin Price said there have been no injuries reported.
The National Highway Traffic Safety Administration said Nissan had not yet provided the agency with a plan to fix the vehicles. Price said Nissan would provide NHTSA with information on the repair in May and begin notifying owners of the recall in June.
Price said if a vehicle's red air bag warning light had turned on, the owner can bring the car into a dealer for repair.
