so, apparently my cobalt decided to fall victim to the passenger front sunroof drain coming undone..... I did a search, and fished through the thread, and saw somebody mention a recall on the drains, but didn't find much past that post about a recall.... so, before I rip the headliner down and see if I can fix the thing, I was wondering if there is any official recall on problems with the sunroof drains on any cobalt models...
