From service ticket - " CUSTOMER STATES THAT WHEN DRIVING IN 20 MPH TRAFFIC, CUST FEELS A SHUTTER IN VEHICLE LIKE DRIVING OVER RUMBLE STRIPS ON THE SIDE OF THE HIGHWAY. ALSO STATES THAT THE RPMS HILL FLUCTUATE UP AND DOWN AT STEADY SPEEDS. TCM UPDATE AVAILABLE. UPDATED TCM PER BULLETIN NTB15-014B"

Software update will do bugger all apart from capture the codes and try to mask the problem, won't fix it because from the sounds of it your CVT is on the way out, the 2013-2016s have a flow control valve in the oil pump that's in the guts of the CVT which is prone to wear. They can swap out a valve body, that might extend out the current CVT a while longer, but eventually the pump valve will f@#k your CVT to the point of no return. It's also something you can't swap out without pulling off the CVT and then removing the bell housing to get at it. (not something you will get Nissan doing)

Have a read of this thread, the more you know, the less BS they can throw at you.
