I've noticed a few times that the engine puts out a "wooo" sound on. Each time I've let off the gas and the sound goes away. I don't know if it is the ANC adjusting or what. It wasn't that loud, but definitely present.

 

Just adding a data point here. It isn't worth mentioning to the dealer. I think what folks are hearing on this thread is a lot louder.

Mine is the same.  Happens about 2200 RPM.  Go above or below and it goes away.  Mine is not that bad and not always there.  As you said I think some are much more noticeable.

Except on long highway trips I don't have the RPM gauge up, so I don't know where it shows up.

I know, as I said, I use it on long highway trips.

i have the drone/woo sounds right at 2350-2450 RPM on the scan gauge usually just under load like going up an on ramp or something if I keep it steady at that RPM. 
Usually don't notice it much with the radio on. lol
