Check your comp. coverage Ultra-View owners - have a low deductable. My wife was heading down the road recently when the roof just let go - shattered and fell into the sunshade - fortunately, the shade was closed. No loud impact - just a unique pop when it completely shattered and collapsed.
As you would expect GM won't even think of this being a defect - even with all the problems people seem to have with this roof. If they admit it's possible it could have been a defect it then becomes a safety issue and that launches the NHTSA dogs. Not to mention it's going to cost over $3,500 to repair and several weeks just for the parts to arrive. The General has lots to lose if this is a defect. The problem is determining what the exact cause was. She was driving around 55mph in light traffic when it failed - no overpasses, no kids or trucks throwing rocks and no evidence of a foreign object that might have caused it.
I hate to think what might have occurred if the shade had been open and the kids in the back seat. Note - that big piece of glass is not safety glass - only tempered glass - designed to shower you - not to stay intact like a windshield.
Not sure I can put the kids back in that vehicle after seeing the potential. Needless-to-say - the wife was a bit freaked out. We loved our SRX, but...
