I was at the V-Club/HOD track day last Sunday at Buttonwillow, CA having a great time. HOD requires that you run with all your windows down (like most open track events). On my Third session, first lap I'm coming into the final sweeper and something goes BOOM!!! - like a sonic boom and I see glass shards. I'm looking around the cockpit but don't see anything...pull back the sunshade to the sunroof and see the glass has exploded. WTF?!?!?!!?????
I pull into the pit and the nice folks at the V-club had some duct tape to seal the hole so I could make the almost 2hr trek back to LA. I was DNF for the rest of the day and only got in a half day of track time.
I go to the local dealer yesterday wanting a warranty ('22 4BW with 8k mi.) and the service guy tells me there is no warranty for glass and something probably hit it. I show him the sunshade is undamaged and for something to break the glass it would most likely had enough velocity to punch thru the shade. He says his hands are tied and that I have to call Cadillac customer service and work it out with them.
Sounds like all BS to me. Google says there is not a rash of Caddy sunroof failures, but coming from the commercial building industry I know all too well how heat strengthened or tempered glass can get a nickel sulfide stone inclusion and break for no reason. Good news is that the glass was $190 and probably 3 or 4 hours of labor when it comes in. I dont know if it is worth the years off my life calling GM. There were plenty of other 4's and 5's with sunroofs - so it feels like it was just me.
