Exploded roof light

[fizz wizz]

We have owned our MOBILVETTA design Admiral K6.5 for less than 2 months and only slept in it 3 times so far.
We parked our van in its shed on Sunday evening and by Monday morning the sky light at the front of the van had imploded, has anyone else had this happen (no accident or stone chip)

I'm surprised it's tempered glass instead of the usual plastic.
Must have had manufacturing internal stresses for it to shatter.

Along them lines but body stresses from differing parking/travelling pot holes etc, would that transfer enough stress to shatter?

Possibly a stone chip and it didn't shatter at the time but later with body flexing.

Were there huge temperature differences - baking in the sun to cooling down in a shed? Shouldn't happen of course but wonder if that could have contributed.

Is it new? What does the dealer say?

As Lenny said , it's normally caused by a small undetected stone chip , usually near the edge of the glass. Then with body flex or even temperature change it will shatter ( being toughened rather than laminated) . We used to see this quite frequently on the little smart Fourtwo with the panoramic glass roof option.

I had a boat windscreen shatter when stationary, it was triggered by heat stress. Cold frosty morning, sudden rise of temperature when the sun hit the screen, big bang and glass everywhere. Probably hadn’t been fitted properly in the first place with proper spacing all round for expansion but it seems likely that the sudden change of temperature triggered the break.
