I just purchased a 2017 MKX Reserve cpo with the pano roof.
I previously had a 2013 MKZ with the same pano roof that behaved a little differently then with the MKX.
On the MKZ when I opened it, it would fully open and once I reached about 50 mph it would partially close to help eliminate wind buffeting. I could then open it fully and it would stay that way no matter what speed I was traveling until I turned the car off.
On the MKX it operates the same way until I reach 50 mph and it partially closes. When I then open it fully it stays that way ONLY until I slow down, for a speed zone or stop sign, and then once I reach 50 mph again it partially closes, again. It does this every time I slow down and then regain speed. Sometimes I just like it fully open even if the wind buffets. Is there a setting somewhere to set the operation the way it operates in my MKZ?
