Any update on this.
Tesla covered the repair as good will?
or it cost you?
I’m outside warrantee coverage, so unless Tesla’s engineers find something there’s nothing Tesla can really do.

I’m putting it through insurance, since I have a zero deductible plan, so technically it’s not costing me anything.

Covid screwing shipping on the east coast is slowing down getting the glass from the Quebec service warehouse, but at least there is a Tesla authorized body shop that can handle the work nearby, so it’s just a question of when the glass gets here.

An odd thing that I’ve noticed is that the cracks don’t grow unless I DON’T drive the car. It’s very peculiar.

Good you are covered.
It is good to know the cost though for someone who has to pay.
I think about this now, when I preheat the car before leaving for work.

Thanks

Cost for a windshield replacement is about $1700.00 from Tesla (labor included) according to guys I’ve spoken with at Tesla and the local body shop.

It’s still weird that this didn’t happen in one of the previous years, as I was a bit more aggressive using the windshield heaters/defrosters until I learned what worked best. Kind of ironic that this happened not long after the new timed departure system rolled out. :D

thank you.
Now I hesitate to preheat the car.

There is very little reason to suspect it was JUST the preheat, otherwise it would have happened in a previous year.

I bet it was several things that culminated in this happening. Could be delayed stress response from a pothole hit, could be random chance, etc.

Bear in mind as well, I have an X with a GIANT windshield. Any other car is gonna be less than what I quoted above, probably about half all things considered.

Nice looking and ready to go!! I wish I had seen this thread when I first started posting, I am a master journeyman glass installer and have tesla experience to boot. I could have dispelled all of these glass quirks and mysteries! Once I have a bit more time, I'll start hitting what's brought up in this thread so far...

So from the original pics posted, seems like a typical impact crack. I wish I could have caught this before your swap over... It is normal to not be able to feel the crack, as it's caused by pressure pushing onto itself. It is definitely cracked on the outside lite. Unless it's an armoured car(flat glass), laminated glass will always be 2 layers and never 3.
Cold (and hot) temperatures do cause the glass to crack, but not if its done gradually. The easiest way to crack it is with temperature shock -- quickly heated from freezing, or cooled from screaming hot. A crack in glass will speed up or slow down based on pressure zones in the glass that are formed as it cools off the mold in the factory.
I love that Tesla's are capable of self calibration of cameras. I spent almost 30k on a camera recalibration system that works on every vehicle that isn't a Tesla for windshield replacements in my shop.
For gforce2002: that glass shop lied to you to duck a warranty. While there are microscopic cracks in every piece of glass, and glass can break all on its own, you should have been provided some form of warranty against this. This is a stress fracture and could be the glass' fault, or the fault of the installer. Either way, you should have been provided a replacement.
The camera needing a physical pitch adjustment probably was an issue with the mounting bracket glued to the windshield. This is a common problem with many ADAS windshield systems. An extra fraction of a millimeter of glue under the bracket can upset the camera angle enough to do this.
My guess is there was a small pit from a rock hit low on the glass and close to the heater grid. The heater grid broke it. This happens all the time.
Gforce2002 post 13: no glass just breaks by itself in time, there would have been a hit, esp on those patriots. They are prone to hits near the sides due to the shape of the glass and the side moulding system. One small, and I mean miniscule rock hit near the edge and they crack. This could apply to Lexus guy posting one before you too, I would suggest running a ball point pen along the crack, especially near the edge and I will bet you find the impact. It'll be in the black area near the edge...
I'm not surprised your Ranger is stumped. He's a jack of all trades, good at it all. I'm a 20 year glass guy, extreme specialist. Worked on just about any car you can name, and prides myself on a job done perfectly... It's my livelihood.
MrElbe is exactly right: temperature shock causing crack travel.
Your crack growing while not driving it: I'm going to guess it's still cold out at night and at some point during the day, the sun is coming out and is directly on your glass. You might have noticed very small changes in the crack, almost like tiny stairs, and then a longer straight section... This is the crack working through a pressurized section of glass before finding an easy path...caused by a temperature change...

Hopefully all of this has been some help to those in this thread. I am happy to answer any questions at all regarding anything glass or related. Have a great day!!

I should clarify, it was the original windshield from the factory that cracked and the glass place was just trying to explain what might have happened.

Right on about the Patriot, that windshield would take hits regularly, often near the edges.

My Ranger and I went over the cracked area, and there’s no sign of impact anywhere. When I say you couldn’t feel the crack, my Ranger went over the affected area and could not detect it externally or internally. He did take up close video, but I didn’t (my iPhone 6S has become garbage for pics and video since it won’t focus anymore).
As it worsened, it got to the point where you could find the crack via touch, but that was after a week or two.

Not going on my insurance. It’s either the installer, or Tesla. This is under 90 days.
oh man, this is craziness. Hard to see zoomed in, looks suspect where it meets the edge. in my professional opinion, looks like the edge was abraded and it cracked to the heater grid. This is a warranty concern, pressure cracks do rarely happen, and can happen more easily if the installation is, uhhh let's say subpar. If it was my shop, I would re-do it and submit a manufacturers claim.

Ranger checked and didn’t see anything that screamed bad install to him. My pictures are pretty crap thanks to my stupid iPhone which refuses to focus on anything anymore. He messaged me via the app and said that the installer is going to put it through under replacement warranty.
