All I hear is a bit of wind noise, and that is only with no audio on !

Steevr,

Not sure if it is the same thing, but my dealer is wrestling with a type of "drone" or "whum, whum" at 2,200 to 2,500 r.p.m, only when the gas is applied. While i am not certain if it is related to the other vibration issues, in our case you feel the whum whum in the feet, not so much in the steering wheel. Also, it gets worse in cold weather or and is much more noticeable when on a patch of straight highway ... like water torture.

Let me know how you make out. Peter

I hear the same thing. It almost sounds like the rear end and only happens under load. My dealer did a number of things and the sound is still there though I've learned to tune it out.
