mainstang,
I had a similar issue with my '08. Yours might be the same:
The source of the leak is NOT from a bad glass seal but from the 3rd brake light. Either the gasket has failed or the light housing is not seating correctly. The fix is to replace both the 3rd brake light assembly and the gasket.
You can verify the source of the leak by pulling the interior trim piece behind the brake light and look for leaks. Ideally a helper can hose the area with water while you inspect from the inside with a flashlight. Mine usually showed up as water trickling down the inside of the glass
BTW, I would not attempt to do this repair yourself. The gasket has adhesive and it requires special tools to remove without damaging anything. Have the dealer replace it.
