sunroof leaking sunroof leaking

My vehicle was parked in the driveway. It began raining heavily. Water poured in first under dashboard on drivers side near emergency brake, then along upper seam of windshield, then around sunroof. As I tried to bring my Hummer into the garage, water came in and was pouring onto the drivers seat. Cold, wet underwear at 6 a.m. on a Sunday morning was definitely not the way I planned to start my day!

From reading multiple complaints and how to fixes online, I would think that GM would recall and fix this problem.

The sunroof leaks very bad filling the roof of the vehicle with water which then runs down the A post channel into the dash and soaks all the wiring. Have not yet figured out how to fix this and am afraid that it will cause a fire or major malfunction.
