The rear window on the 2025 Nissan Sentra shattered for no known reason. The car was parked in my driveway, was OK when I locked it up a 3pm to go for a walk, and when I got home at 3:40, there was a big whole in my back window. None of our neighbors heard or saw anything, and there are no ring doorbells that could have a video of what happened. Police came and looked at it, there is no evidence of a rock or bird hitting it, and no sign of a BB or any other projectile. It appears to have spontaneously shattered. This is not covered under warranty, so I wanted to report this in case there are other reports that could trigger a recall.
