On one morning two weeks ago I heard a loud pop sound from my garage and came out to see that the top glass was now cracked on my Model 3. The car was parked in my heated garage the night before. I'm guessing the popping sound was the glass breaking on its own. I know with 100% certainty that it wasn't cracked when I last saw the car the previous night since I'd done a thorough micro-fiber wipe down after parking it that night and cleaned the windows, including the unbroken top glass.
When I took it to the Tesla service center, they said it was a rock chip that caused it. They said it's possible that a rock chip could hit the edge of the glass and for the crack to form later for various reasons. I'm still skeptical given that I would have noticed a rock chip while cleaning (because I'm pretty OCD about that sort of thing). Also adding to my skepticism: the front edge of the original glass actually sat a bit lower than the windshield, which always bugged me. That lower edge would make it really difficult for a rock to hit the edge.
Naturally, I think it's a stress crack that should be covered under warranty. Tesla doesn't agree, unsurprisingly.
In any case, I still got the glass replaced by Tesla for a cost of $1200. Which, frankly, seems insane. I've replaced windshields that have sensors, cameras, and heating elements that cost less to replace than that. The top glass in a Tesla is no where near as complicated.
Now I have a new problem. The front edge of the glass that Tesla replaced now sits considerably higher than the trailing edge of the windshield, though not uniformly. It's higher on one corner than it is on another. The attached pics try to show that. It might be tricky to see, but it looks like the edge of the glass is about 3-6mm higher than the trailing edge of the windshield. That seems likes a perfect recipe for the glass breaking from a rock chip. And it's straight up sloppy work too. The inconsistent height of the glass edge sticks out like crazy even when just looking at the top glass.
Is there anything I can do? Can I dispute the "rock chip" diagnosis, and fight for them to cover it under warranty? Can I have them install the glass properly?
