Just to update you all - a few weeks ago NHTSA concluded at least their first phase of the investigation. They draw no conclusion besides to accept GM's contention that these roofs are failing from outside influences (i.e. stones), even though this is the thickest glass used on the market. You can read the entire NHTSA request for information, and the response from GM by doing a search on their website for their investigation numbered PE05052. It gets a little hard to follow, but it appears there have been 17 confirmed unexplained roof failures with too many injured in these incidents. Why they simply seem to roll over for GM's explanation is hard to understand. There have been no design changes for '06 and NHTSA expects these incidents to continue as well. It appears the next part of their investigation goes to engineering analysis - whatever that entails.

It also appears most were repaired under warranty except for mine. That's Cadillac customer service at its best.

Sorry to hear there's another member of the shattered roof club. Hopefully Cadillac took care of you better than me.
