Sudden windshield lamination failure

Coworker of mine has a 2015 S550
He said he came out after work to find his windshield had about 50 of these little bubbles in the center, as well as some Frost looking formations around the edges and camera.

From other manufacturers, I'm familiar with delamination, just sharing this cuz I've never seen one happen like this in just a few hours.
I mean it's hot here, but it's still within the normal range of Earth LOL

Yes, that is an original Mercedes windshield. I believe it's either the IR or the acoustic, I'll check the VIN later

Wow, it looks cool though ngl, looks like how a snowflake will look like. Dare I say it looks beautiful.

Um... sorry back on topic, sorry it happened though, will be interesting if the cause will ever be figured out.

This is a really bizarre situation that clearly is a defect in the original glass.

That doesn't at all mean that aftermarket glass is as good or better than OEM glass. Its not an MB thing, its any manufacturer. If you want glass that pits and is wavy and doesn't match the OEM tint then by all means get Safelite glass lol.

MB glass (from what I read at least) also have some sort of infrared light protection for those who don't have windshield tint (like in Canada where it is completely illegal), to some extent prevents certain wave lengths of light from entering, including harmful ones that affects the health of the passengers.

Seeing that we have never seen anything like this before, I think the odds of that are pretty small. Every aftermarket windshield I have ever been forced to accept has been how I described.

Yes we all have different experiences.
I have never found an aftermarket windshield with defects.

This is the first to post on here about this issue but that does not mean it is the only one.
Not like every MB owner in the world is posting on here about everything that goes wrong with their car. - Just the cool ones post. LOL

This is first picture of a bad windshield I have seen where you can see issue in photo. Normally an issue is so minute does not show up in photos... and having the wrong color tint band on top does not count

Point is MB is not perfect (far from it) and never will be and they can ship junk parts and lemon vehicles like every one else.
They are not on the top of the Quality food chain anymore and far from it which is what is a bummer...

First off MB doesn’t make glass. No manufacturer does. An outside company makes glass to their standards and specifications.

They’re not “defects” per se, but they are differences. You may not be able to see the differences but EVERY aftermarket windshield I have ever seen out in the world has tint that doesn’t match 100%, and it just looks different than the rest of the glass on the car. I can spot it from 15 feet away. You may not see that or it may not bother you but that doesn’t mean those differences aren’t there. On top of that the ones that I have had are just not as clear and smooth as OEM glass and they don’t hold up to wear as well.

Why would having the wrong color tint band not count? That absolutely counts. The fact that doesn’t bother you proves my point that you’re clearly just not as detail oriented about this as we are and that’s fine.

There is a reason why people want OEM parts on their cars and a windshield is no different than any other part.

This is a one off defect, the things we are describing are widespread characteristics.

If you enjoy aftermarket glass that’s great. It’s not going into my car.

we agree to disagree.. which is cool...

My point is aftermarket glass is not as bad as everyone makes it out to be - DOT says they are fine.

As for color once the stock glass is gone how am I gonna remember if the new one is exact copy..
My eyes and memory are not that good

I bet, when MB gets glass from its different suppliers the color is slightly different; bet it probably different from same supplier as nothing is perfect in this world and hence hy engineers thought up of having tolerances on drawings.

Anyone find that tint band actually does anything?
I mean I still have to use my sunvisor when sun is blinding thru this tint band...

This person recently posted a defect in the mesh area for radio waves to pass through on the acoustic comfort glass:

https://mbworld.org/forums/gls-class...t-package.html

He thinks the sun caused the mesh to delaminate btwn the sandwiched glass.

"Its fine" doesn't work for me on my $125,000 car...I've paid an insurance company many many tens of thousands of dollars over the years, they can buy me a part thats the same as the part that was damaged.

Its like any other aftermarket part. Aftermarket parts are manufactured without the license from the OEM, so they basically reverse engineer their own design to fit into the car, instead of using the design provided by the OEM. So, they are never exactly the same. Try and bolt up an aftermarket bumper or something...it never fits 100% right, in fact it actually can't be.

We are not making this up:

https://www.motor.com/2022/06/oem-gl...'s%20brand.

What is OEM Auto Glass?
When manufacturing cars, auto companies bid out the privilege of providing auto glass for their products. The winning supplier will then have the consent to fabricate glass to the exact specifications of the carmaker. This company holds the distinction of being an Original Equipment Manufacturer or OEM, and any windshield it produces is referred to as OEM auto glass.

In terms of thickness, color, shape and fit, an OEM windshield is virtually identical to the original windshield it’s replacing. And since OEM auto glass makers are duly licensed by auto manufacturers, the OEM windshield they’ll provide will likely bear the carmaker’s brand name and logo as well.

What is Aftermarket, or OEE Auto Glass?
While OEM auto glass is made by suppliers partnered with automakers, aftermarket auto glass, also known as Original Equipment Equivalent (OEE) glass, is fabricated by auto glass makers without the license of car companies. As such, they cannot stamp their products with the carmaker’s brand. They are also legally prohibited from making exact replicas of OEM glass. This is the very reason there’s a marked difference between OEM glass and OEE glass in terms of thickness, shape, fit and tint.
As for color once the stock glass is gone how am I gonna remember if the new one is exact copy..
My eyes and memory are not that good
Because the car has other windows that you compare it to. The windshield no longer matches from the outside or the inside. You also may have fitment issues, wind noise etc

I bet, when MB gets glass from its different suppliers the color is slightly different; bet it probably different from same supplier as nothing is perfect in this world and hence hy engineers thought up of having tolerances on drawings.
Made to the same specifications its very similar, but the point is it will match the other glass on your particular car.

Anyone find that tint band actually does anything?
Absolutely, my S560 doesn't have one and I miss it.
