This morning sunroof exploded while driving on the highway. I have a regular (not panorama) sunroof. This is a year old 2023 C300 with 8000 miles. I was lucky that the shade was closed. Planning on taking it to the dealer this afternoon. I saw a few messages with this happening on a few MB models. It will be a fight to get it covered under warranty but will see. Anyone has any input?

Glad you are okay and not injured. That sounds terrifying that it happened on the highway.

I would report to dealer to see what they say. Do you have comp/collision coverage? I would personally probably report it to insurance incase dealer pushes back. If you do have to go insurance route there are a lot of rules about reporting an incident in a timely manner. Sometimes the insurance will do the chasing if it’s a defect.

I'm also glad you're ok. What a terrifying experience. This actually seems to be an industry wide issue with sunroofs. I think you should report your experience to NHTSA. The more complaints NHTSA gets, the more likely they might do something about it.

Good luck. I had a 2023 C300W4 with the panoramic roof and it suddenly exploded. The dealer wouldn't talk about it being their responsibility, and I had already called insurance. So insurance put together their own quote, and so did the dealer. While the insurance wasn't real happy, the Mercedes dealer did the work. It was a little over $8,000USC to get it fixed. The insurance company was interested in the information I found on the web about they spontaneously exploding like mine did, but I don't think they went after Mercedes. I was driving down the interstate at around 75 when it happened. The shade was closed so only a small amount of glass ended up there, most of it flew over the car. As they got done with the repairs, we saw that a great deal of the glass must have struck the trunk lid, causing numerous chips and scratches in the paint. That was going to cost almost $3,000 to get repaired. Before we were able to do that, the car was stolen! Now I'm waiting for my new 2025.

Thanks everyone for the well wishes. Will take it to dealer tomorrow and see what will happen.
