Anyone experienced broken exterior door skins? Had one appear to "shatter" at the lower leading edge on my wife's '05 Vue. No evidence of impact on the panel or anywhere around it, but it does look like the lower edge of the panel might be unevenly screwed to the door frame. Found some mentions at groups.google of cracking on SL door skins from about 5 years ago, but nothing since. I may be kidding myself, but she's been SO careful with this vehicle, and the surrounding area is so clean that I'm inclined to think something very odd may just have happened.
