Something is wrong with my panoramic sunroof. There is excessive crosswind noise at 75mph and above. Anyone has had similar experience? I scheduled a maintenance service tomorrow to get it looked at. Fortunately it is still under warranty.

I have windnoise at 100kmh when roof is opened and then closed on odd days. Trying to bring her in for warranty.

Apparently panoramic sunroof is a weak spot in MB and this is a very common problem. I am really glad this popped up while this thing is still under warranty. I am reading this could cost about $3500 if out of warranty.

Which model C43 do you have? Coupe or Sedan?

I also add that nothing seems to be visually wrong with the roof, and all parts seem to be flushed and lined up. Also no irregular noise when the roof is open or tilted. Weird high pitched noise is only present when roof is completely closed at 75mph+.

Same. Only way to tell there is some wacky windnoise is when you compared to open or tilt status and when fully closed, sometimes there is wind whistling noise. Luckily, it's not present all the time, only when the roof has been opened and when closed, there might be the "whistle" annoying as ****.

Good the dashcam worked all those time I am freckin out, can't wait to show to the service...

After hearing the weird noise all weekend long this morning I was not able to duplicate it on my way to the dealer, of course. It is completely gone now but I am sure it'll be back again.

I have issue with my panoramic sunroof in my sedan all the time too. Whenever I open it - it'll leak some air after i close it and have a little whistling noise. Annoys the hell out of me. Luckily - after a few hours closed, the sound will go away. I've taken it into the dealership 2 times for this issue and each time it's the same result. Just about given up.

Exact same here. I’m out of warranty now, so at this point I’m hesitant to open it beyond just cracking it.
