Vibration and drone like sound at 50mph

[bigbwb]

Hey guys.
Don’t recall my other 5th gens making a slight “droning” sound and vibration while holding gas steady at around 50 mph. If I let off it disappears immediately. It’s only occurring in 5th gear. Haven’t contacted the dealer yet, just curious what others think.

Thanks!
