THe sunroof is tempered glass. That makes it deliberately stressed internally.
Some sunroof glass may be TOO stressed.
Google brings up tons of Hyundai roofs breaking. Not too many others.
Then the fact more sunroofs aare replaced in xxx canada, than anywhere else. (and the blame is placed on the type of gravel they use there in roadwork.)
So I do not read ANYWHERE that Ford sunroofs are some giant danger.
I personally never heard or saw a sunroof break.
My rear hatch on a 1989 Tracer self destructed but it was a junkyard replacement for accident damage to hatch, which broke after using the rear defrost.
The insurance Co forced the dealer to replace it again no cost to me.
Then a back, side window on a Buick slightly open (it was supported on only two edges in that position) , was rapped with just a knuckle and 'popped' into a million pieces, right into the face of the person seated there.
So for some tempered glass, even a little hit could 'pop' the glass.. And because of the internal stress, the glass could explode 'up' even if hit from small rock outside.
This is my 2 cents.
