Same whistling here, at least on the driver's side. haven't tested passenger side.
i'll try the felt tape fix and go from there. i don't have the time to mess with the dealer and for return trouble-shooting trips, etc.
DOES ANYONE HAVE PICS of the seam/gap that the tape should be affixed to?
oh and btw mine is a 2011 w/ less than 1800 miles. noticed this problem a few hundred miles ago.
