I am experiencing the same
I am experiencing the same issue with a 2020 Forester. I've had it for roughly 4 months and driven less than 3000 km. Last weekend the windshield cracked from the top edge, over the passenger side EyeSight camera, half-way down the windshield, before turning towards the drivers side and cracking horizontally. The windshield cracked while making a left-hand turn at city driving speeds on a smooth paved surface. We have been experiencing big changes in temperatures from day to day.
The dealer service department took pictures of the crack and contacted Subaru. Subaru stated that they would not replace the glass under their stress crack policy, insisting that something must have damaged the glass.
I've examined the crack with my calipers and can't find an area along its length where something larger than 0.5 mm could possibly have hit it. Very frustrated with this experience. I am concerned I will continue to have issue like you are encountering, and at an approximate OEM replacement cost of $2000CAD for parts and service, I'm wondering if an aftermarket product is a better bet from a durability perspective.
