Crack in pano roof

[steilkurve]

Hey all. Just noticed two small cracks within the back half of my P3D+ pano roof (Sept. 18 delivery). You can’t feel the cracks as they are within the glass it appears (can’t feel it from inside or out when touching). Obviously, and especially given location, it’s not resulting from a rock impact. See attached photo. Anyone else? NP

Glass defects were reported in February 2019 Consumer Reports.

Good to know. Anyone got theirs replaced?

You'll might need lots of diplomatic skill to get Tesla cover your cracked glass under new car warranty.

Some got them replaced with no trouble. Others have a hard time convincing Tesla that it's manufacturer's defect.

Good luck!

I think you’d have a hard time proving that’s a design issue. Seems a bit of a peculiar place to crack. Maybe someone hit it from inside? Or maybe something hit it from outside? You wouldn’t have to feel anything for it to be impact damage either.

On my old STI, I was driving under a tree and some pine cone or something fell out of it and dented my roof, for example. I was stopped at a stop light when it happened. Clunk! Wasn’t thrilled...

Yeah but there is no sign of impact. Nor can you feel anything. An impact would have left an outside mark. Ian’s the lines are perfectly matched and symmetrical. Seems like an odd coincidence. No?

If you have no sign of impact, you should be good since it is the first thing they will look at.

No. Because I don’t think that an impact on glass has to leave a mark. I’ve seen cracked windshield with absolutely nothing you can feel.

I agree with your assessment that it's not caused by an impact but rather by manufacturer's defect.

The defect spreads out from the heating element: some look like a line, others look like small round bubbles.

Notice that I am no expert and the last time, Tesla didn't agree with my assessment either.

You might need to go to a Tesla approved body shop and ask for an expert opinion in writing and show that to Tesla.

If that doesn't work, bring your proof (Consumer Reports, body shop expert letter) to small claim court.

Good luck again!

did you use your rear defroster? I know my glass warps when it is on

I have actually. Several times over the winter months. But just noticed now.

So I just got my Model 3 back from the service center. They replaced the back half pano roof glass, no questions asked. No charge. Said it was a known defect. They did a good job. Can’t tell it’s been replaced. They did induce two very small tears in the lining near the glass in the process, but I think I will leave it alone for fear of fixing it creating other issues. See attached. Sometimes it’s better to leave well enough alone. Plus, when you don’t zoom in on it with a camera, it’s not really noticeable. Overall though, I’m pretty amazed at the quality of the service I got. Especially when you consider that the service center was overwhelmed. These guys work hard!

Wow, that’s a really strange one. I doubt you’ll have issue under warranty. But it may be a long wait.

Some owner posted that someone from a Tesla said the robots set the glass in too hard. Your failure makes me think it’s defective glass, defective design, to thin or something.

In some ways I hope the back log is due to Tesla realizing there is a design issue or QA issue on the glass itself and fixing it.

See my update later in the thread. They replaced rapidly, no questions asked.
