I'm hopeful that the conditions that caused the frozen windows and doors will be relatively uncommon for me. It was relatively cold, < 10F, and so with the car warm enough to have liquid moisture on the outside, when you stopped it didn't take long for everything to freeze up. The design of the base of the window on the X is interesting. I'm assuming it's the same as the S, but I'm not sure. With most cars there's a rubber seal that goes a little ways up the window, and then flairs out to the door surface, so water running down the window is pushed away from the window. However, on the Model X there's an actual trough at the base of the window between the glass and the chrome trim, and a tiny fibrous seal agains the glass. This seems to create a perfect place for a small amount of water to pool, and then freeze if it's cold. I'll have to experiment to see how it functions, perhaps water slowly drains out of it somehow? Anyway, seems like an odd design, perhaps only done for looks? But very impractical in cold weather it seems.
Love to hear reports from others as they do more driving in freezing temperatures, especially after leaving the car for more than 4 hours in those conditions.
*TIP* Turn off the auto fold mirrors if there's any snow and ice build up so they don't strain the motors when they can't fold or unfold. I wish there was a way to make the spoiler stay up, since the trough created by the space under it gets so packed with snow and ice that it can't close itself all the way unless it's carefully cleaned out every time you park.
I'm also going to experiment with using a credit card or drivers license if this happens again to see if I can get it between the glass and the seal to clear the the ice. Couldn't get it enough with a scraper.
Oh, and if you actually WANT to do donuts, or drift the car, you can! Turns out going into settings and turning Slip Start seems to pretty much disable traction control and you can go sliding around quite a bit if you have a nice open parking lot!
For anyone who hasn't read the whole thread, I have Nokian WRG3 tires on 20" rims, and the car drives great in a wide range of snow and ice, just more the "gadgets" that have some issues.
