There is an air bag light that illuminates when there is weight on the passenger seat but the air bag will not be deployed, maybe because the vehicle thinks there is a dog, small child, or inanimate object sitting in the seat. The trouble is that the "air bag disabled light" occasionally turns on when my teenage sons sit in the passenger seat. The dealer says it is because my sons do not always sit squarely to the back of the seat; that is, they occasionally slouch in the seat. I have videos of this behavior which I can send to you, so you can determine it is is something you would like to look into. Nissan's response is akin to steve jobs saying of the iphone 4, "you're holding it wrong." I think Nissan should build their sensors for the way people sometimes sit in their seats, not as the way they would like them to sit under idea circumstances. They probably have one sensor at the back of the seat, when they actually need another in the middle and maybe one at the front to better judge the weight of the object in the seat.

When my 90lb daughter and 130lb wife sits in the passenger seat of our MY14 Nissan Leaf, there is no consistency with whether the airbag will be on or off. Often, the airbag is on with my daughter and off with my wife. The dealer has "reset" the airbag four times and says "it's working as expected". I've spoken with Nissan electric Consumer Affairs and they said there's nothing they can do and they refused to let me talk to their supervisor.
