Fista st 2016. The issue started from the tail light fixed the issue. Now i noticed when i park incline with the front up hill water started coming from the roof, took the headliner off and the water is coming from the end of the rail of the sunroof. Made sure the the drain hose was not clogged, nothing in its way and I am still having the issue. took it to a body shop, because dont have warranty anymore, to see if the can fix the issue and it went away for like a week or two. They just put black silicone around the plastic that holds the drain hose. I took it again and they dont know what to do, there just brushing me off and saying its a bad design from ford. If anyone had this issue how did you fix it?
