What to do? Already took it to the dealership?
Putting the ventilation system into recirculation mode is going to change the pressure differential across the seals. If the mirror is either allowing air into the door cavity through the mirror stalk or is generating some sort of turbulence causing a weird low or high pressure area along the window seals, changing the pressure differential could still make a noticeable difference to a problem caused by the mirror design.I don't think it's simply an issue with the mirror design (as some have suggested)
I wish I had waited!I am newly registered. I in market for new SUV. I drove Palisade and heard wind noise and Ask shop Foreman and He told me all them was having same issues and Hyundai Engineering was working to find a fix. I think I wait check out Genesis Gv80 or 2021 Palisade when they come out. Later
