Exploding Panoramic Sunroof?
Around 7 AM in the morning, on a mostly open 4 lane highway, my sunroof literally just popped and shattered, with glass falling inside of the car. It was a surprisingly loud 'pop' sound. I was accelerating from 45 to about 55 when it happened. I wasn't sure what to make of the whole thing, but I've since seen that Mercedes has been named in a few class actions over the issue.
MBUSA customer support assigned a rep to my case about a month ago, she's been 100% nonresponsive since that time. Dealer is saying they're unable to help, that Mercedes suggested an 'outside force' caused the failure. Car is a 2020, still under extended warranty.
Anyone else had one of these things pop on you?




The manuf. obviously will blame on external factors such as flying debris which may coincidently land on top of your sunroof.
I would suggest just claim thru your insurance as getting proof of manuf. defects is extremely hard to prove.

Dealer also would not cover - I claimed under insurance. Had to replace the sunshade as well, which was the big expense as they needed to drop the headliner. Still have some glass fragments under the headliner which rattle and drive me crazy, but dealer will charge again to pull it out.
Was a pain and it took 6 weeks to fix, but has been fine since. I think MB should fess up the the problem, but when I was going through it they claimed it had to be a foreign body.

It's absolutely reprehensible the way they've handled it in my case and the pattern I'm seeing in reading the legal filings from other customers is identical, they have the same excuse. I'm evaluating the most efficient way forward, meeting with an attorney shortly and will see how things progress.

I had mine tinted to 20% ... if it does explode, perhaps the tint film may hold all the debris in one 'laminated' sheet.

Got repaired after a couple of attempts but left me feeling like this isn't a long lasting solution. Kept that car will over 85k miles without an issue in the pano roof department though.
When I went with the w213, I opted for a regular sunroof no pano. Then I got reintroduced to the sliding back of the cover under acceleration (forgot about that from previous AMGs lol).
Also without the Pano roof, I thought I was in a hailstorm the first time I drove in rain with my 2021. It was so loud I panicked and drove for cover.

Silent inside in rain with the BMW while my MB sounded like I had a tin metal roof in the rain. Btw my MB also had the acoustic package while the BMW does not (not an option)
