Two problems related to air bag light on have been reported for the 2015 Nissan Leaf. The most recently reported issues are listed below.
My wife sat in passenger seat and closed the door. We noticed that the air bag indicator was sensing that there was no one sitting in the passenger seat (air bag off).
The passenger side airbag deactivation indicator keeps going on signifying air bag is not functional even though there is an adult seating there.
