Loose front drive-belt pulley

[DD's DM Voyager]

Just had my 2011 Voyager in to the dealer to check out a clunking noise from the engine which I noticed while backing out of my driveway one day with the bike turned off. I also noticed a whine from the left side of the bike which slightly quieted down when I pulled in the clutch. The mechanic found that my front drive-belt pulley was loose, and once tightened it corrected both the clunk and whine.

The service manager said they put in a message to corporate because they'd never seen or heard of the pulley working its way loose (it was also covered under warranty). Might be something to watch for as I'm sure it would have been all kinds of crazy if it came off while riding.
