I am having this problem and the dealer has been absolutely no help. My neighbor bought one too. It helps to have the recycle air button on.I just got a new Palisade. When i test drove another palisade before buying this unit, i did not hear much road noise through driver window.
But in this Palisade when i dive >40 MPH it feels like air trying to gush in type of road noise. Is this normal?
