Watch my Cybertruck ceiling glass spontaneously crack in near real time

[beatmstrj]

So I went to go pick up a new TV this afternoon and while loading the TV I noticed my ceiling glass had completely shattered. There was no impact anywhere and it spread all over the entire glass. I park in the driveway and have a camera monitoring events so I decided to go back through the footage and noticed that it happened yesterday. I don't have 24/7 recording so I only got footage every time someone walked by, but it was enough to see the whole progression throughout the day. It was a pretty hot day (about 100F), but my CT is parked in the driveway every day so this wasn't unusual. No one, and no water touched my car that whole day.

At 10:38am was the last time there was no crack in the glass. In the next photo you can see the crack starting in the top right corner. It didn't seem to have any predictable flow to it.

With each timestamp you can see the progression of cracking. Around 7p it had fully cracked as much as it was going to crack.

Not tinted, but I did install the mesh headliner sunshade thing it came with.

Update: After setting up a service appt for the glass and it getting rescheduled twice by Tesla due to no parts available and then cancelled by Tesla for no apparent reason I finally got into the dealer to get this replaced. I think they were a little baffled by the spontaneous nature of the fracture. They had two different people closely examine the glass looking for damage (I don't really blame them I guess) they weren't able to find anything so they approved the no-cost repair. New glass has been installed. They didn't bother to reinstall my sunshade but maybe they wanted the glue to dry. Anywho, all better for now.

Whoa! Some kind of thermal expansion issue? Fortunately, you're 100% covered under warranty for that. Fairly common on new vehicles, happened on my Saab and my Wrangler when they were brand new back in the day.

Yeah, and large number of glass objects will have some just fail. Any microscopic imperfection will create a failure point in the future.

I live in Florida. It's really hot.
Where r u??

Was it tinted?

Was it tinted?

good question. I would like to know as well. Was both the front windshield and the moonroof tinted and if so, what percent of tint is on each? sometimes seeing these sporadic issues makes me have second thoughts. last thing I need is time taken out of my day to go and attend to a new vehicle I just spent all this money for.

I had the same issue with my windshield and had no point of impact anywhere. For sure warranty will cover it, they couldn’t explain it but the day mine cracked the interior was like 120 degrees and I had a sunshade up. ??‍ for how big and flat the glass is worries me for future stress cracks. **FYI it took almost over a week to repair if they have the parts already.**

Did you have any extra tint or the sunshade installed? I am wondering if reflecting/rejecting more heat into the glass can increase the chances of this happening. Regardless this should be a warranty issue.

I park in the driveway and have a camera monitoring events so I decided to go back through the footage and noticed that it happened yesterday....

A while back I ran some simple tests on sunscreens placed inside in an office environment. Temperatures were about 110F at the base, rising to 180F at the top. This was because the sunscreen placed vertically has a pretty uniform amount of solar converted to IR for each foot of height, and it all adds up.

Although one feels cool in the room, all that hot air is heading toward the ceiling and eventually goes into the AC return. Thus it lowers the efficiency of the air-conditioning.

As a result, we moved the sunscreens to the outside of the windows and had much improved results.

Here, you can't easily move the sunscreen to the outside. And since hot air rises, we can consider it as "trapped" between the sunscreen and the glass. So, will the glass handle 160-180F temperatures reliably?

Most people don't understand that any automotive sunscreen reflects a certain amount of light, and turns another part into IR - heat. Of that reflected, a fraction successfully goes back out thru the glass, and another fraction doesn't. The sunscreens that are best at their job are the silver ones. That is not what the Cybertruck ceiling shade is.

The overall end result? It's pretty easy to have a net result of zero from a sunscreen. You don't want it to feel cooler in the cab because hot air is trapped between the sunscreen and the glass - that's an illusion, your AC must remove heat from the cab.

Also, people are correct to question tints and coatings, as they also affect these issues. Unfortunately that area is clouded by marketing claims to the point one can't believe anything.

I live in south Louisiana. I set my “cabin overheat protection” temp to 90 degrees. I have not had the battery drain substantially because of that temp yet.

It might not help but i'm glad i keep mine in the garage where it's 75. Who knows what will happen in winter?
