Broken front window :*(

Broken front window :*(

Just noticed today my front window is already cracked. Must just be Colorado driving with sanded roads. Car is not even 1 month old yet.

Anyway, I was wondering if anyone had replaced their front window and if there was anything special I needed to tell the glass replacement company.

I, too, live in CO (Evergreen), and cringe at that "whack" sound that often occurs when driving a day or two after a good snow fall. I will have my S in a few weeks and have been wondering the same thing as to whether or not anything special is needed whenever I need to replace my windshield.

I diligently get those small chips patched ASAP, which helps keep the windshield from cracking, but with the sand and gravel CO routinely uses on snowy roads, it is inevitable that I'll need a new windshield every year or two. Good thing I did order the paint armour to protect the body.

jat | 28 December 2012

By "front window", do you mean the windshield? If so, I thought that was the normal mark of someone in CO to have a cracked windshield :).

pilotSteve | 28 December 2012

Call Tesla ownership RIGHT AWAY before you schedule your own glass repair! Reason: I had my car in for some other due items and the service center said "oh, we found a crack in your windshield at the bottom near the wipers so we replaced it for you under warranty".

I think he said the robot assembly process can stress the glass. I would let Tesla see what they will do as it could well be you had a latent or hidden defect. :)

Thanks, I will ask about the warranty possibility. Yes I meant windshield.

kelly | 28 December 2012

Sorry to hear about your windshield Scorch. Living in So. Cal. It's less of a concern, but still a concern. I got excited when I learned about a "windshield skin" (like body armour for the windshield), but sadly the curvature of the Model S windshield is to complex and they were unable to make it work. It's also a large windshield too, and I'm guessing they won't be cheap to replace. Good luck with it!

Brian H | 29 December 2012

When it's replaced, ask for a bigger EPass hole in it!

MichaelHMB | 29 December 2012

I had a windshield crack within the first couple weeks of delivery. Needless to say i was very concerned as i haddent hit anything and to the best of my knowledge nothing had hit me. I called support and the tech knew exactly where the crack was, lower right side, without me telling him. Tesla was very good about replacing right away at no cost

MrB | 1 January 2013

Same this just happened to my Model S this afternoon. I was at a friends house and when I took him for a ride he noticed a 3 inch crack in the bottom of the windshield just right of center (barely visible from the driver seat)..

There is no visible impact on the outside, it looks like a stress fracture, so I guess I'm one of the unlucky few with this issue.

mlovely | 8 January 2013

I noticed crack in my windshield today. Wasn't there when I left work (or at least I didn't notice it), but upon entering my garage saw a crack originating from the top just to the passenger side of the rear view mirror.

jgdds | 8 January 2013

I too have had a crack develop on the driver side originating from the edge, not due to any object hitting it. The people at Tesla have been very nice every time I call, but have yet to call me back with any information. It has been over two weeks. Understand the holidays must be hectic, but really. My call to them tomorrow will not be as nice as the crack is progressing across the windshield.

Brian H | 8 January 2013

Someone said this was standard on late-model premium cars, intended to break up sun reflections off the hood when it is at low angles to the horizon. Cracking is a flaw; the distortion is not?!

guppie | 12 January 2013

I had my windshield crack overnight, right bottom extending to the right edge. As with other cases above there is no visible impact. It has been around freezing here in the Bay Area overnight so I'm guessing it is built-in stress pushed to the point of breaking by contraction from the cold. Hopefully Tesla agrees this should be covered by the warranty.

This is my first real issue. Otherwise the car has been behaving flawlessly over the first 1100 miles.

Mark2131@CA-US | 14 January 2013

Caught a rock in the windshield last night. Tiny crack at impact point. Maybe I should wait for my lower right corner to crack before I try to fix it!!!

petero | 14 January 2013

Mark2131. If I were you, I would have a auto glass shop plug and seal the crack ASAP. Little cracks have a way of becoming big cracks. It is not expensive $30-50 but could save you big bucks.

smd | 23 January 2013

My passenger discovered my cracked windshield in the lower corner about 6 inches total. I called Tesla service and have an appointment for replacement under warranty.

Hogfighter | 23 January 2013

There might be an issue regarding this. Way, way too many windshields have cracks.

Brian H | 23 January 2013

what, 10-20 out of 3000? Half a percent?

Timo | 23 January 2013

Half a percent is quite high when you talk about that large amount of cars. Elon talked in one of the videos how they could use SpaceX manufacturing methods to make variability between different cars really really tiny. I think half a percent failure for one rather impotant part of the vehicle in SpaceX would not go thru, so I guess they are not using SpaceX methods. Same thing with doors, too much variance between cars.

Del Mar | 26 January 2013

Noticed exact same crack this morning in right lower corner on passenger side. Reverse L shaped. 9" long. It becomes more visible with direct light over head. Tesla service center acknowledged that they had heard of this problem. Has anyone had replaced yet?

Brian H | 26 January 2013

Yes, it's a stress fracture, and several replacements under warranty have been reported.

jp158 | 26 January 2013

WOW, Very interesting and a major concern!

Tesla needs to apply some attention to this, nothing worst and important as having a secure front windshield, and with the price of the car it's just not suppose to happen!

If that's happening this early in the release what else is going on!

pilotSteve | 26 January 2013

My windshield was replaced the week after delivery when I left the car at the service center for a detail job. Service manager said he noticed the crack and replaced it for me.

So yes I think there is an assembly and/or vendor issue here. Not huge but significant. I do feel that Tesla is on this one as there has been no "push back" from service, they just replace the glass.

jjaeger | 26 January 2013

Already noted and reported that they had to work on how the robots work with the windshields during production process. Am sure that they'll get it all ironed out. Costing them a little in the mean time, but not a major concern in my book.

skystream3.7 | 26 January 2013

i have 2 cracks in my windshield lower right and upper left. Upper left was first

jbunn | 26 January 2013

Was in the Seattle service center this last weekend. Saw several boxes of windshields from the factory. hmmmm

Robert22 | 26 January 2013

Sounds like one half a percent is going to be low... | 27 January 2013

Had a crack this morning. 1/3 of the way up the windshield on the passenger side. Near as I can tell happened overnight parked in my garage. posted this on a separate thread (couldn't find this one)

Brian H | 27 January 2013

BIG crack. Get it fixed fast. The windshield might split when travelling at high speed and decapitate everyone in the front seats.

Hogfighter | 28 January 2013

@Brian H -

These are only the ones being reported on this forum. Like cockroaches, if there are several posted here, statistics would indicate that there are many more out there.

I had a crack on delivery, another on the same truck had one as well, same spot. Saw another in the store in November, same issue.

I'm curious if it's how the robots are assembling the windshields, or is it caused by torsion and stress of driving. One is an easy fix, the other not so much.

Has anyone heard of the replacement windshield cracking?

Chuck | 29 January 2013

Anyone notice distortion along bottom one inch of windshield?

Brian H | 29 January 2013

Many people. It's standard/common due to the 'complex curvature'. Some have developed cracks in the lower right edge, requiring replacement. Someone claimed it was a deliberate feature in luxury cars to break up the hood glare for the driver; don't know about that. | 29 January 2013

I was told that my windshield crack was a product of over-torquing the windshild at manufacture. I have not heard of the problem appearing with replacements. There is no after market windshields so the replacement will be Tesla manufacture.

DouglasR | 29 January 2013

I had a Jeep Grand Cherokee the first year they came out, and I had to replace the windshield three or four times, I think because of torquing.

Damian | 30 January 2013


Damian | 30 January 2013

Brian H Is there sufficient hood glare to make that an issue as well? (I never heard of deliberately cracking the windshield as a solution for anything)

Hogfighter | 30 January 2013

Hood glare isn't an issue for my car, and the distortion doesn't bother me a bit (although it is there, and may bother some)

Brian H | 30 January 2013

The distortion was supposedly intended to break up the reflection. Not the crack. Duh.

Andrew18 | 31 January 2013

Mine just cracked. Passenger side midway up The A pillar, horizontal about 5" long, then downward like a dogleg for 1". Bummer. I'll call Chicago service center tomorrow.

smd | 1 February 2013

I just had my windshield replaced by the Fremont Factory's Service Center. I was told they would get it done in one day. It turned out that they finished it at the end of the work day and didn't want me driving it right away (let the adhesive cure for a few hours), so I picked it up this morning. I had the Enterprise rental car provided by Tesla. The windshield looks great now. Initially, the service advisor tried to say it started from a chip and tried to make me pay for it. What he was claiming as the chip was barely visible and but you did feel a small divot as you run your finger along the crack. Maybe it was a small chip that started it, but there are chips like that on ALL cars of ALL makes and it does not result in a crack, so that would still be a design/manufacturing issue that the windshield cannot stand up to a tiny chip like that. I insisted on having it covered under warranty and after he briefly spoke to the manager, it was covered.

While I was there, I shared a ride over to Enterprise with another service customer. She was getting her rear child seats installed, but she said that she's had her windshield already replaced twice and is now on her third windshield. That one also has a crack on the driver's side that started with a chip from road debris. It really does seem like the windshield is much more fragile than those on other cars.

smd | 1 February 2013

FYI, the charge from Tesla for windshield replacement would have been $975 plus tax. Has anyone paid for a replacement?

Getting Amped Again | 1 February 2013

Just my opinion, but I think this is a serious design flaw, not a supplier or manufacturing issue. I believe the curvature of the windshield causes bending stresses during thermal contraction, and the glass doesn't "float" sufficiently to accommodate this. The only solution is to give the glass room to move without restraint during its contraction. That's going to require more clearance and/or a less-stiff support method, which might be accomplished by using a support elastomer that is less sensitive to cold temperatures (easiest fix).

Again, total conjecture on my part.

Andrew18 | 1 February 2013

I spoke with Chicago service- I was told they needed a pic of the crack to send to TMC, then they would order it and I will get it replaced in 1 week

Robert22 | 1 February 2013


I completely agree. If some owners are on their third windshield, I think that merits a look at the glass, the design, and the installation. If a windshield is already under stress, and a rock hits it while driving, it is much more susceptible to shattering and could potentially become a safety issue. More information needs to be provided to owners about geographic distribution of the breaks, etc.

noel.smyth | 2 February 2013

mine just cracked today... exactly as described in one of the prior comments, on passenger side between a third and half way up, runs about 5 inches and turns down an inch or two. no dings in windshield.

Andrew18 | 2 February 2013

Maybe someone can e-mail Elon- I hope he knows about this. | 2 February 2013

This is a known issue to Tesla. My first (last?) replacement happens Wednesday. They determined it was under warranty. There was no road hazard that caused the crack.

Robert22 | 2 February 2013

Given the similarity in the crack pattern presenting on different vehicles, I'm sure Tesla will quickly be able to define a root cause and propose a fix.

bsimoes | 3 February 2013

This makes me really nervous. It sounds like people are having to go to a service center to have it fixed. That would be a 200+ mile drive for me, which would mean an entire weekend, complete with an overnight in a hotel. The "Windshield Doctor" is a mobile company that can fix windshields where the car is...does anyone know if this is something that rangers can do?

Vawlkus | 5 February 2013

No, a Ranger cannot replace a windshield on site, that's shop work. Tesla will pick up your car though, and save you the trip & overnight stay. They'll also provide a rental if need be. Call it in and see what happens. | 6 February 2013

bsimoes- The windshield replacement is manufactured by Tesla. The installation is being done by a local auto glass company (in my case, this morning). You would not be required to go to a service center for this.
