So I have had my 14 Gt since Dec. long story short. When in recirc or Max AC the cabin has a whistle when going over 45 mph. Annoying as hell. Dealership can't hear it. I have recorded and video'd the phenomena. It is audible on my iphone and even my wife hears it. Windshield gap. Rubber seal bad. Dealership says the blender door and AC are operating correctly. On to the next dealership with my video. Anyone else have this issue?
