Very minor leak
Yes; I've heard it's a Jeep thing. However, I do not recall anyone posting a leak in this manner.
It's not anything serious; however, I have a leak on my JKU's driver door window. It seems to originate from within the window track at the top of the window and trickling in. Oddly, it's also where it looks like the pieces were molded together so there is a slight difference in the contour. This is about 3/4" forward from the rear vertical part of the weatherstrip/track guide.
Anyone think this is worth raising as a concern with the dealership?
