Picked my Model 3 yesterday in Orlando and sure enough... 2 hours after signing the paperwork, we were driving home on the highway and heard a huge rock hit the glass. Not a truck in sight either. Quickly looked at windshield and there was no damage so I thought it was ok.

Looking over the car later in the day though, noticed a fabulous chip in the glass right behind the windshield with a 6 inch crack behind it. Sigh.

Anyone know the cost to get the middle roof glass replaced? I keep seeing costs for the windshield but not the glass piece right behind it.

Will be calling Tesla Monday morning when they open. Thanks!

Ouch! Sorry you had this happen. Let us know how it goes...

Do you have "Glass coverage" on your auto insurance? I'm not sure if they would cover the roof glass but I'd ask them first. In some states, like AZ, if you have glass coverage there is no deductible by law.

For what it's worth, just a few hours before my scheduled 3 delivery in January, I got a call from the Tesla Service Center in San Diego saying that they had discovered a crack in the center glass during pre-delivery detailing. They wanted to delay the delivery until they could replace the glass. I proposed going ahead with delivery and I would bring the car back for repair when they had a new glass piece in hand. They said that a crack in that glass panel was considered a safety issue and that they COULD NOT deliver the car as is. Fortunately, and to my surprise, they got a new glass panel from Fremont and delivered the car just a few days later.

Wow! sorry to see that happen to your new 3! Looking forward to seeing how things work out for the replacement work.

Driving down the highway today, my son and I hear a singular loud pop. Neither of us saw anything hit the car, nor heard any other impact noises, or for that matter felt any kind of impact. I look over at him and say "that sounded like glass cracking." We look up and we have a tree like crack in the over head glass panel. When we finally pull over and look and there isn't any sign of impact to cause it. It was pretty weird. I've called Tesla and sent them photos, waiting to hear back from them.
The picture is looking down at the roof, but you are seeing the reflection of the bikes hanging overhead from the ceiling of the garage.

I hope Tesla gets these glass cracking issues under control.
Glass cracking will always be a thing. Its extremely common among cars in general, and Model 3 has a *lot* of glass. Rocks are one source, but a lot of cracks are spontaneous (temperature changes, other sources of stress, etc)

With tens of thousands of Model 3s on the road, even for the relatively short period of time so far, I expect a lot of reports of cracked glass, even if the rate of cracks is no different from normal.

Wish someone could find a way to make glass that's not prone to cracking, but it's really the nature of the beast. If you look at any random piece of glass under the microscope you'll see that it's covered in microcracks, from the get-go - all of which have the capability to propagate. It's common to add internal compressive stresses in glass (tempering, toughening, etc) because glass can take compressive stress incredibly well (pushes fractures *closed*), and it means that anything put into tension at first just relieves the internal compressive stress.

That's not to say that there isn't an usually high rate of glass breaks, or that Tesla couldn't do more. I don't have the data to know that. But... glass will be glass. Very high compressive strength, tiny tensile strength, self-propagating failure modes.

Can you please confirm where this crack is located as it’s hard to see from your picture. The reports that I’ve seen are commonly at the front edge of the middle section. See this other thread. https://teslaownersonline.com/threads/roof-glass-stress-cracks-vol-2.7156/

The other reports of cracked roof glass were in very early build cars. @PTC Gator took delivery just shy of 2 months ago. I understand @KarenRei ‘s point about natural prevalence of broken glass in a given population. I explain that almost on a daily basis when discussing potential side effects of medicines. However, the reports of glass cracks appears to be in the same location which is more suggestive of a stress induced crack as compared to a random crack or one related to glass quality which could happen anywhere.

Ben at Teslanomics also had a spontaneous roof glass crack. He said it was covered under warranty as it was a defect in manufacturing for some vehicles. (stress fracture)
Yep. He had a very early build and many were hoping it was resolved. We shall see.

Great connection @Brokedoc . I replied in the other thread, but the spot, propagation (thanks @KarenRei for the great word), and the shape would pass for Irish twins if the cars were side by side. The top part of the "T" on my car isn't as pronounced as his, but I imagine if I were to drive some more it would. I'll try to get some better photos or even video just for the community's reference.

Some better photos. Used a Crazy Glue pen just to show where the crack starts. It's hard to see from some angles. I didn't glue anything, it just has the right size and contrast to stand out (and it actually would sit in place).

Waited 2 days to hear back from the service center, went ahead and called them to get a definitive answer if possible. The roof is under warranty and will be replaced at no cost to me. Like Ben Zullinz, it wasn't caused by a projectile or accident, just presumably stress or manufacturing defect. It will take a few days to get the parts to the east coast and they will call to schedule a service when it arrives. I will get a loaner, just no idea what that might be until I bring the car in. No more than 3 days in the shop for the repair (and maybe a firmware update??).

Is there such a thing as crackedglassroofapobia?? Cause if so...I now have it.

I have quite a history with projectile damages with past cars and even with my 3. Even in the short 2 and a half weeks between delivery and my full front PPF install I had a healthy hit on my hood, tried to touch it up before the PPF...looks Ok...but I know it’s there. Then I took another hit no less than 3 days after PPF install on my passenger door, where I don’t have PPF of course. Still have to touch that up.

I even had my tint guy telling me that he heard reports the the back window “could” crack after installing tint due to increasing the heat levels of the glass. He wanted me to know that he heard of this possibility before I gave him the go ahead anyway.

...and now you are telling me the roof can crack without even being hit !! :eek::eek::eek:
