i would imagine a quick spray with a water repelling lubricant would sort the hinge out. As for the window not going up. I remember reading somewhere that a few people have had this; the anti-trap sensors were interpreting the window touching the seal as an object in the way of the window closing, and dropping the window down again. A simple reset of the window position at the dealer will fix it.
