There is indeed a design flaw by Lincoln. The windshield pillar molding is the issue. My dealer taped off the giant opening and the noise went away. The wind noise is at 60 mph+ and very bad when it's windy.
There are 2 pictures I'm posting, 1 of the 16 MKX pillar molding and 1 from a newer Mercedes pillar molding. You can see Mercedes has the right idea with a smooth windshield pillar molding. The MKX is a C-channel catch all for wind. (It's especially bad in cross winds) This isn't Mercedes rocket science because the 2015 MKX was smooth without noise.
We made Lincoln aware of this and they claim to be working on it. (yeah right) All owners should have dealers open a complaint with Lincoln to push them for a fix.
This was a terrible job by the Lincoln engineers who designed a $61,000 luxury car.
