2020 Sprinter shattered window !

[DBinSD]

After our month long 5k mile maiden trip. I washed our unit.
While pulling into our storage facility with all paved roads. I made the last hard left turn.
During the turn our left rear window (emergency exit) blew out onto the pavement.
Has anyone experienced this?
Warranty is stating (glass is not covered) but, what keeps this from happening again and again?
I have appealed with a short video showing the metal frame flexing about ½” with light pressure.
