Well, I THOUGHT the 'shattering' sound was gone after the dealer re-placed/re-glued both A-pillar mouldings again... but the sound is back. It had been making the shattering sound between 58-64 mph... but that stopped. Now if I go 65 mph, the sound is back. I took a drive out to the desert over the weekend and heard it all over again. I'm going to give up on it and just turn up the XM. It's not worth the hassle anymore.
