I recently experienced a sudden crack that appeared on my 2023 Y for no apparent reason. I wanted to post a picture, but it’s too difficult to capture a good photo because of the angle and lighting. I’ve read several posts about other people experiencing the same thing. I hope this isn’t a common issue ! I’ve booked a repair and they are sending someone to replace the glass. I can’t see how they can do it onsite at my home, but I will leave it to them. The cost is over $1700 !! I believe wholeheartedly this is a manufacturing issue, as I can’t for the life of me see an impact point for something might have hit it. The crack begins just under the rear view mirror/camera and extends to the passenger side about 7 inches. Any help in understanding what might have caused this and do I have any hope that Tesla will stand behind their quality.
