I just got back from a round trip from Texas. While there I saw temperatures displayed as high as 113F on the MME display - that's probably higher than actual, but it was hot. The car spent a lot of time parked in the sun. At home, it's always garaged.
Out of the blue, I come out to the car and discover two distinct cracks in the roof. Dealer has taken pictures and is contacting Ford.
There are no signs of impact anywhere.
My guess is that there are internal stresses in the glass due to either the manufacturing of the glass, or assembly procedure. Heat adds to the stress until it cracks.
