Oh I think it can most certainly happen. But my Fusion Sport sunroof glass flew completely off the adhesive. It was maybe 4 months old at the time. I took it to Ford, and they made every single excuse they could even saying it must have been a rock chip. Except there's no sunroof glass or fragments because it flew clean off. They insisted it was a rock chip. Turns out it is a ploy with all automakers/dealers/OEM because none of the glass is covered under any warranty. I am not sure about Tesla but with Ford/Lexus/Porsche/whomever as soon as you drive the car off any glass damage is on you/insurance even if it was a manufacturing defect. I showed the glass separation to a friend that works for FCA (at the time) and she said what probably happened was they waited too long to put the glass on and the adhesive started curing.
There's also a known issue with F-150 rear glass exploding/cracking due to the defroster causing issues. Also Explorers with rear glass that explodes randomly.
And I can spot rock impacts fairly easily due to the cratering and small glass powder usually left behind on the front windshield. Probably not as easy on glass roofs since the powder can get blown off.
