Dealer acknowledges the vibration and noise. Said they test drove a new one with fewer miles than mine (which as about 200) and it had a worse vibration. Drove anothe customer's Rogue in for service and they said it was there but not as bad as mine. Thier conclusion: it is a characteristic of the rogue and I should ignore it and it may go away.
That doesn't sound right to me.
Any suggestions or information on this from others?
