Exploding sunroof??
I have a '22 CLA 35 AMG. While driving on the highway with light rain, my sunroof suddenly *exploded* into a million pieces. Sounded like a gunshot and shocked the hell out of me. Nothing hit me (that I could tell) and I did not hit a bump in the road or anything.
It's sitting at the dealer right now as I wait for a call back from MB Customer Service. I'm seeing lots online about class action lawsuits against MB for this exact issue.
I'm glad the screen was closed, or else the interior (and me) would have have been showered in broken glass. WTF?!?!?
Why don't people ever put their location?
I filed a report with NHTSA's website yesterday.
I also spoke directly with MB USA yesterday. They are looking into whether MB will pay part or all of the repair cost (initial estimate is $1800). I'm not optimistic MB will actually pay anything. If not, I plan to contact counsel for the class action suit.

Good luck. You may be surprised that MB may cover everything.
I remember one person saying it happened while parked in his garage so there was no way something hit it.

They're offering nothing.
This will be the first and last Mercedes I purchase.
The Best of Mercedes & AMG
If you find other owners that have experienced this, make that known as well.
You said you filed a complaint with the NHTSA. I would follow up or file a second complaint and include Mercedes' response. Include all this information in your appeal. Become a "squeaky wheel". Mention that you are active on a number of social media platforms (MBWorld, Facebook, LinkedIn, etc.) and are happy to share your experience. In the mean time, get the roof replaced (check your car insurance for glass coverage -- tell them you were hit by a meteorite or other space object) and keep all of your receipts.
Sorry for your problems. That sux. I'm beginning to think it is best to NOT buy a Mercedes new, but rather get one 7-10 years old that has good maintenance records. Good ones have had all the problems worked out at someone else's expense.
The estimate of course keeps growing. In addition to the sunroof, they will also replace the sunscreen due to the likelihood that pieces of glass damaged it. It doesn't increase my immediate cost (i.e., my deductible) and is a good thing since the repair shop now has to remove the headliner. I'm hoping that means they should be able to get all of the little pieces of glass so I won't heard them moving around up there.
At the end, I'll have the full repair but I'll always be wondering when the sunroof might randomly explode again. No more pano sunroofs for me, and no more MBs based on how MB and the dealer acted.
I did contact the attorney leading (one of) the class action cases, but no response.
WRT whether owning another Mercedes or not, you likely would have been met with a similar response from any other manufacturer. Even Honda would not cover a (prematurely) deteriorated sun roof seal on a CPO car. But I know how you feel. Still, I would look very closely at a Honda CR-V over a Mercedes GLB if shopping for a new or used car. I own or have owned a total of three Mercedes after years of being a VAG guy and will likely get another used Mercedes if I need to get another car. I was serious when I said a Mercedes a few years old is probably a better deal since these cars depreciate quickly.
I found this article stating the companies that use laminated sunroof glass. It's disappointing that Mercedes doesn't laminate their panoramic glass with the acoustic package.

dealer quoted 5k here in California.
based in what you shared looks like there’s nothing they’ll do about it. In fact, I have dash cam video of when this happened + I had an MB Roof rack and an AMG roof box limiting the possibility of a rock or something hitting the sunroof
Finally about a month ago, dealer told me MB agreed to pay for parts, I'd pay for labor, they couldn't keep it there any longer without a decision. I agreed, and it would have been around $3000. But the day I went to pick it up and pay, they told me MB USA had agreed to cover the repair.
Meanwhile, I had submitted a lemon law/ buyback claim, and it finally got approved. Sedgwick is supposed to contact me with an offer within the next week.
Car is fixed, though I am scared to open the sunroof, and it drives fine. But I think I'd like the 450 instead.

I'm glad MBUSA agreed to pay for it. they declined my claim and gave me a 1000 service credit instead, initially the MBUSA rep said 500 but quickly changed his mind to 1000?! anyway I had to go through insurance to get this fixed and used a portion of my 1000 credit towards my deductible.
- Something breaks.
- You think it is a manufacturing defect.
- You are out of warranty (or not).
- Manufacturer denies claim (for whatever reason).
- Insurance will cover damages, not malfunctions/defects.
- Pick path of least resistance.
