There have been several reports of noise issues with the rear windows rolled down. Basically a thrumming noise, it's quite loud. It's a common problem with other cars too, not just Nissan. I can think of at least 3 other cars I've driven with the same problem: 1987 Honda Accord, 1999 Ford Escort Wagon, 2002 Mazda Protege.
As for solutions, there is no permanent fix. you can try playing with different window positions, crack the front windows open a bit, etc. I have not heard of anyone trying window vent visors as a solution, but it may work.
