2024 E 350 panoramic roof exploded. Mercedes Benz Canada will not provide warning
Our car was four months old and the rear portion of the panoramic sunroof exploded.
A third party looked at the roof and said it wasn’t a rock, so did insurance. Mercedes Benz Canada will not warranty their product.

Oh no : ( not on the W214 already, it happens, it is an issue across multiple brands, different brands react differently though. I wonder what recourse you have, hopefully something good. Good luck OP.

The dealer didn’t even take the time to look at it. I called Mercedes Benz Downtown Calgary and over the phone they said it was a “rock”.
It wasn’t a rock.
The only concern they had was my 1 star google review!! I was generous.
They did suggest an auto body that I could go to as they don’t have the ability to repair it themselves and they would appreciate the parts order!!!
The roof panel may take 3 to 4 months as it is in back order.

Mercedes Benz Canada made the decision.
They opted out of the government of canada arbitration process just a week before our roof exploded. It would appear that the process didn’t treat them well. Other manufacturers are still part of the process.
The pictures taken by the third party were submitted to the dealer and Mercedes Benz Canada after they said they still wouldn’t cover the damage under warranty.
Insurance will cover but this is a cost all consumers bear as it should be a responsibility of the manufacturer of all brands.
Laminated glass would go a long way in preventing this problem.
The insurance company said this is becoming quite common.

This is indeed troubling. How was it determined that a rock or other hard object did not hit the glass? Im not saying it was a rock or something similar, but curious how it was definitively ruled out.
Also, what was the car doing when the glass roof exploded? Was it parked? If so, where? Were you driving? Did all the glass land in the car or did some/most go outside of the car?

Auto glass company inspected it. They had seven that month and their store alone. Mostly Hyundai. Pictures were taken no foreign debris and outward explosion.
We were on the highway exiting at roughly 80 kilometres. The roof exploding sounded like a gun went off. There was a 30 degree centigrade temperature as the weather got warmer over a four hour period. The liner was fortunately closed so the glass did not shower into the interior.
I had inspected the car in morning as it had never spent anytime outside of an underground parkade. I’m very particular and the car is thoroughly cleaned once a week.

I have inspected many 2024 and 2025 e-class models as I don't like the fitment of the rear portion of the panoramic roof. All models exhibit the same characteristics- the rear portion is raised ever so slightly at the back of that panel. And if you follow the rubber seal at the parallel edge to the car - it meets the glass at the front, but quickly falls away as you move back due to the rear portion of that section being raised. Not sure if this correlates to the failure.

Regarding cause, I don't see how the absence of foreign debris is anything conclusive. A rock traveling at 100kph from being kicked up by another vehicle hitting your car/roof traveling at 80kph could easily land far enough away to never be seen again. Plus, with it being outside, I'm sure there were plenty of them all over the place where you stopped to inspect. I suspect the lack of a rock or foreign debris in the car is what was meant, but its quite conceivable that a rock could have hit it and bounced away outside the car. If the car was motionless in a garage then I would say its highly doubtful, but driving at 80kph its much more plausible that something hit it rather than it just spontaneously exploding. I know it happens to glass though. I had a glass shower door shatter when I was sleeping. Nobody was near it as it was 3am. Glass was everywhere.
The anecdote that seven other cases with most being Hyundai is not really relevant since they could have all been due to external factors and its different cars with different glass. There are hundreds of thousands of cars with all glass roofs that don't explode for no reason. I'm sure some do and have. Maybe yours did, but its just as likely (perhaps even more likely) that something hit it.

We kept the thumb drive of the outside camera and there was no traffic present. It’s a pretty rural area.
Mercedes Benz USA is involved in a class action suit in regard to exploding sunroofs, evidently this is not an isolated incident.
The insurance company also agreed that is was not a foreign object but did agree to repair the car. BMW, Hyundai and Mercedes are prime culprits.
I was told by the insurer that court action is very difficult as the manufacturer will make this a very long and expensive process.
Again the consumer comes out on the short end of the stick. Higher premiums for consumers that have panoramic roofs and a manufacturer that passes the liability to the consumer.

In any case, I hope you get this resolved. Had to be pretty scary when it happened. MB should make this right. At least insurance is covering it.

I end up finding several threads (on different models) talking about the tinted sunroof causing explosion but like I mentioned, OP unlikely tinted it:
