Just bought a 2020 GT last month, what a fantastically quick, fun drive! When I have my side windows cracked open . (vaping) I'm hearing a somewhat faint whistle from the side mirrors at 35 - 55 mph. Normally not a problem w/music on I'm usually scooting faster along my way. When I hold my hand in front of the mirror, the whistle goes away and a 1 inch piece of electrical tape on the forward edge of the mirror silences the whistle. So I went back to the dealership took a ride w/service ngr. and he agreed, definitely a wind induced noise. We also drove another 2020 GT on the lot and had the same results. Question is - has anyone else experienced this phenomenon with their 2020 GT and is there a easy fix? Who wants to put a piece of tape on that gorgeous black chrome. lol
