I have the exact same issue with my 2017 KT. I bought EZE gutters and put them around the top and sides of the Pax and drvs windows and that has helped somewhat... but the amount of water off the roof, like your video shows, is too much for them to direct away that much water from the window. I just went out in the rain to clean out the weeping holes and see if they are clogged up or not flowing draining freely to the outside.
