I have a 2019 5th gen sport. I love the truck however I have this annoying whistle on windy days. It has nothing to do with the the air. I have turned everything off and everything on. I have set recirculate to on and off. I have opened and closed my side view mirrors. Nothing effects this sound but the wind and the speed. I have taken it to the dealer but they are unable to reproduce the sound. It only happens on windy days at high speed. The sound seems to be coming from behind the dash just above my left foot. This is several short clips pieced together. Around the 2:20 second mark I speed up just a hair to show how bad it gets as the wind increases. Sounds like a train whistle when I speed up to pass someone.
