Vibration and whistle noise in rain

With my CX 60 Built. 2023/07 in rain from about 130 kmh a annoying whistle noise, which sucks badly. The tires are not, already changed. Now we have found by chance that it stops, when I fold the mirrors electrically, is of course no solution at 150 on the highway. Does anyone have experiences there? I have almost 40 Tkm down and am only so semi-enthusiastic, total failure after 12 Tkm was already there, with engine damage!
