1 guy can do it, I have seen it done a few times. If it was me I would want OEM myself

 

Wow!
I thought I was going nuts trying to figure out why my windshield cracked from the inside and now I come across your post and see that I am not alone. WTF is up with this crap GM?
Im sure they know of several of these windshields cracking like this only to say they are not aware of any other ones. BS!!!
Here is mine...



I think I'm just going to have a tint strip put on it for now To cover it up till it gets worse but I would expect better from a $130.000 GM car!

 

My 2015 Z06 just developed this crack, same exact place. No impacts or damage to the outside of the glass, just delamination inside the windshield. With all the others having the same problem it's obviously a manafacturing problem, but with a 5+ year old vehicle, what ya gonna do?
Sux.

 

My 2015 vert top failed resulting in it free falling & slamming the windshield frame & cracking the glass and yes it cost me $1ooo plus the cost of a new motor for the convert. You will get away cheaper than I did.

 

I have no idea whey that comment is valid, as my mother used to say "What does that have to do with the cost of Tea in China?" Nothing. Windshields crack. They are made by glass companies that make the windshields for many brands of vehicles including GM brands. OEM glass is sourced from all of them by ordering a part number. Factories don't waste the time, effort and dollars to make a lower quality glass for one Customer Vs another Customer because they may pay a higher price. They use a standardized procedure to produce the best quality they can produce and they don't vary the procedure. In manufacturing you quickly learn quality is free. Poor quality is expensive. It is always cheaper to build a high quality product. Do it right the first time since it costs more to do it over. Glass will be the same quality for a car that sells for $20K as one that sells for $500K.

After running at the strip huh? I would like to think a combo of UV degradation and body flex did it. Maybe there's is the tiniest imperfection in the edge of the glass or the car itself and it just needed the weaker windshield and that grip twisting the car enough.

 

I had the exact same crack. It was internal to the glass. You could not feel it from the outside. Service manager at Randy Marion in Mooresville, NC took one look at it and got me a new windshield under warranty. This was three days before warranty expired on my 2015 Z06. He said this was a known problem. It was not caused by the top slamming down hard or by hard track driving. I believe there was a piece of "slag" used for putting the windshield in place that caused the problem. Installers of the replacement glass were told to file down the slag. After thousands of miles, the problem has not come back.

 

yeah. That's what I'm referring to. 5yrs of UV weather wear, torque causing flex, road vibration and imperfections. Lifts. that sealant eventually breaks down so does the structural integrity of laminated glass. There's resins glue... so it weakens a bit. The car flexes a bit. And a piece of that slag just happens to make contact somewhere and crack...

 

And then there are the MILLIONS of cars out there with the same 5 PLUS years of usage that HAVEN'T had these problems. Whether its UV, or torque flex, or whatever, the point is IT SHOULDN'T BE HAPPENING.

It's a defect from the manufacturer, period. Making excuses for GM doesn't change the fact that we have to pay to fix their problem.

 

you're right. Bit in these few cases it's luck of the draw.. not making excuses for them. Heck if you're the original owner go back to the selling dealer and them investigate. If crack caused by slag (diagnosed and documented by glass imstaller) i bet gm would pay... but again. Its called goodwill for a reason.

2nd 3rd 4th owner. Different dealership? They're going to save those goodwill jobs for their own loyal customers. I was in that business for years when younger. Worked for Ford and Jeep/Chysler/Plymouth/Eagle. I know the process.

 

I have a 2016 Z06/Z07 with same delamination or cracking on passenger side up top near a-pillar. Put car away for winter and it wasn't there.... uncovered it and discovered it. I reached out to Kai Spande who I met at Ron Fellows Track School and sent a picture. He asked that I send my vin. # to Jeff Strauser who I met at Corvettes at Carlisle. I did that and heard nothing. I followed up with Email back 4 months later.....still waiting? Nothing I caused and needs to get covered and made right. My issue was discovered after storing my car in 2018 and taking it out of storage April of 2019. Still under warranty and I have extended plan as well. Also have wheel and glass coverage when I bought the car. Car had 8500 miles on it when discovered. It should not be any out of pocket expense. I am worried about factory seal and potential leaks in the future? I don't want a bad issue to become worse. Can I live with it on $ 108,000 car or $20,000 dollar car irrelevant.

 

So you don't even know whether or not he got the email and you never approached the dealer to see if it would be covered? Not sure what you expect.

Windshields crack on all brands of cars. Sometimes when they are new and sometimes when they are old. However, most don't crack. The Corvette is the same. Sometimes it is covered under warranty and other times it is covered with insurance. Over 55 years of owning my own cars I have replaced 6 windshields or about one every decade. Some were sand blasted, one was vandalized and others just cracked. Luck of the draw.

Hi Bill, thanks for responding to my issue. The truth is that Kai did respond when I first reached out to him by text. We had a nice back and forth conversation about our Ron Fellows Weekend. He requested I send my Vin and pictures to Jeff Strausser and to Inform Jeff of our conversation and issue. He stated he had spoken to Jeff and that he was looking for my communication. I proceeded to send all of my information and heard nothing. I sent a second email to Jeff a few weeks later. I still have all of them saved. When I brought it up to my service tech at my dealership he documented all this information. Life happens....time passes....and those guys launch C8 platform. I am sure they have been busy. Went back to have my oil changed this May and was told by my service tech that he got a call and was told they were going to cover windshield and they were aware of problems. They told my dealership that they would reach out to me to work out details. Never got any communication from them. So you see, it's not fair to suggest I haven't done my due diligence. I sent Jeff and Kai another email after this information was disclosed to me. No response, with covid 19....it is understandable and may be reason. I have had many cars as well in my past, one 35 years old. Never seen this happen with glass without taking a rock. I know every spot on this car. I spent money to have Expel Ultimate and C-Quartz applied. So there is no confusion here...and I think it's important point to mention. I cleaned car and put it under my cover in November and uncovered it in April and it was there. It appears to be a stress fracture at the top passenger a-pillar. It developed during it winter hibernation here in New Jersey. My garage is not heated and we had temperatures well below 20 degrees that winter which doesn't happen every year. It's not about the cost to me at all. On principle if there was a impact from a object I wouldn't of reached out to Kai. I am nervous about having a company like safelight pull a factory windshield and install a replacement. Definitely going to involve my dealership and have them set it in motion, they have been great.

 

Bill, This was a known defect that GM covered under warranty. As mentioned previously, the service manager at Randy Marion in Mooresville, NC said it was covered as soon as he saw it. The crack in my 2015 Z06 windshield was at the same place. Many other owners had their windshields replaced under warranty.

 

I emailed Kai again today and mentioned discussion on this forum regarding front windshield. He promptly returned my email and is looking into issue with my Vin #. He is thinking it already has been cleared for replacement in the system and will get back to me. That's positive progress and a great sign. Looks like third time may be the charm...

Can you share that information by PM so that I can get my windshield covered as well. Maybe with the more phone calls that they get about this issue the more they will realize that it's a problem that needs to be solved.

Thanks and glad they are going to take care of you.

 

Update: I had a crack form on my 6,000 mile 2015 Z06 just as others are reporting on this thread. I called Hagerty and they paid 100% for Safelite to expertly install a new OEM HUD windshield. Unoficially Hagerty said that if this was my only claim, it would not affect me on renewal. Work done at Fairlawn NJ Safelite shop. I am really pleased with Hagerty and Safelite.

 

Just pitching in that I paid $750 here in Arizona for an OEM windshield installed with hud.

Be careful with your insurance they will try to pull that crap by using aftermarket glass sometimes, but for the C7 there aren't many or even any aftermarket glass options at least in my area when I was calling around.

Luckily it was a lot cheaper than our 2019 BMW 3 series that also had a crack that same month, ended up costing me $1,160 for that one.

What's really funny is I use to be on the other end, as a kid my dad use to own an auto glass place. I guess I had to pay back some of that lol

 

In SC we have state wide 0 deductible on glass breakage. Is that not the case for other states?

 

It's optional coverage in a lot of states like Georgia but it's a cheap premium and well worth it.
