Yeah maybe too late; but it could still happen for the 2018 model:
The armrest is too high. Get someone who is 6'4" and has long arms and have them sit there. It makes my shoulder hurt if I use it. I have to keep my arm in a raised position to be able to use it.
Do away with the CD player in the base radio and add either or both a USB port and Bluetooth. Using the line in jack with an Iphone is tedious.
How about let customers order any window placement they want? One rear door window instead of two? A window on one side only? Should be able to do that.
Should seriously consider doing up an electric model. Put one or two Leaf packs in it. I would have bought my current NV as electric had it been available.
An upgraded security lock for the back door would be nice. Also plexiglass windows as an option. If my two front windows weren't made of glass; that would be a huge boost for vehicle security.
Maybe even consider doing a version of the vehicle that is low to the ground. Some applications would prefer that.
I'm really surprised Nissan doesn't offer a cutaway version of the vehicle to the RV market. Or offer an enclosed cab with exposed rear frame rails for applications that want that.
I've owned a lot of vehicles and this one is by far the most useful vehicle of them all. Pure utility and function. Just such a machine. I enjoy driving it everyday.
The general public doesn't know:
The NV is built in Canton Mississippi.
Is based off the Titan(hence the truck front end).
Is on a full frame(IE, a real frame).
4 wheel drive? Diesel?
I still think and feel this vehicle should be marketed more along the lines of the old full size Blazer and Bronco or even Suburbans. It seems more like those vehicles then it does a traditional van. A van to me was what it was because of that dog house the engine was in. The promaster/transit are more minivan like in their construction.
The NV should be marketed as a complimentary vehicle to the TItan. Like the Tacoma/4 Runner. More of an SUV or enclosed version of the truck.
