Shaolin...
I too had the loose middle light on the top..it was causing a funny noise when I drove during rain or mist. A little tightening worked and all seems fine for now. Did not have the leak you were talking about but someone on the old board had posted about a leak that extended all the way to the on star buttons.
Keep an eye on it and report it to GM so that they can work on it. Also GM said that they had a problem with the seals not lining up and coming off and this was causing a leak of some sort as well.
