inhabe a 2013 XTS. Got in my car this morning to find that my Cue screen had shattered sometime overnight while parked in my garage. After reading on here, I see that this is quite common. I’m out of warranty obviously. It was extremely hot here yesterday. Looking like an extreme temp change can cause this. Is this defect something Cadillac will fix or am I at the mercy of what the dealer charges to fix it?
