Good video of a windshield leak at the top left corner. If the sun roof where to leak that bad you would be wet at the point of the leak. My next door neighbor works for a glass replacement company and he sees this a lot in the 2015 and 16, Fords and Chevys. He says at times when he removes a bad windshield that they do not have the sealant in the upper corners. But a good find on your part and thanks for the link! I have had my Raptor for 5 days and had two bad rain storms and washed twice no leaks and no rattling of any kind. Also own a 12 Explorer that has the big sunroof and has never leaked.
