Check the door pillars and make sure they aren’t lose at all. VERY common on 2015+ For them to come lose up at the top. Wind will push through it while your driving and cause a whistle. The glue they used to attach the clips pops clean away from the plastic. I repaired mine by using 3m double sided auto tape. It has a thin foam in the center and grips well. I haven’t had the problem since.
