"The affected vehicles may have been built with driver or front passenger seatbelt assemblies that may not properly latch or that may not unlatch when the release button is pressed," said NHTSA in its recall summary.
It added: "A seatbelt that does not properly latch would not restrain a user, increasing their risk of injury in the event of a crash. A seatbelt that does not properly unlatch when the release button is pressed may prevent the occupant from quickly exiting the vehicle in an emergency, such as after a crash, increasing their risk of injury."
Nissan spokesman Steve Yaeger told Edmunds there are no accidents or injuries linked to the recall.
The affected Armadas were built from April 30, 2015 to June 5, 2015.
Nissan dealers will inspect the front seatbelt buckle assemblies and replace them as necessary. The recall is expected to begin in early October. Owners can contact Nissan customer service at 1-800-647-7261.
Edmunds says: If you own a 2015 Armada and notice a problem with the front seatbelts, you'll want to make a service appointment now with your dealer. Other owners can wait for their official recall notice and then contact the dealership.
