There are plenty of 4X owners that are noticing this condition. If you read my post you will see that i stated that the "handling" of this issue is entirely up to nissan motor corp.
Stop with the driveshaft already, the frequency of the vibration is much too low for that to be the cause.
Just log you complaint with your dealer and have them contact tech after checking the basics.
Just trying to help and save you guys multiple dealer visits. It will be resolved when nissan forwards the info to the dealers.

Cheers,
