lots of posts if you search.

mine was bad for a while, had to help it close by hand. when it got very bad, the dealer replaced the "module"( i think its the entire tray that holds the sunroof) under GMPP. Would have been about $500 or 1k I think.

Now I onmly open it after I brush off the twigs, and I no longer crush my kids superheroes in it when they fight.

After the squealer repaired it, they left one drain hose disconnected, and it leaked over to the A pillar. That took a while to figure out.
