I just joined the group whose sunroof glass cracked, 2016 Edge SEL.
I keep the interior shade closed during the summer to keep the sun from heating the interior. Last week, I opened it and voila, two cracks going from front to back.
I took it to a friend who owns a body repair shop, he ordered the OEM glass from a Ford dealer, and it's replaced. The glass coverage on my insurance covered the whole cost.
