I was driving around my neighborhood one day with my panoramic sunroof open and at the red light i wanted to close the sunroof (california summer sun is no joke) and it made this really big 'THUMP' noise, thought the sunroof glass cracked. After the big THUMP noise, the sunroof wouldnt close and this is after the light turned green so i am driving slowly because there was rattling noise coming from the sunroof and didnt want the sunroof to fly out from the car. So i had to pull over and try to figure out if its okay to drive with stuck sunroof with it rattling noise. after that i tried to close and open the sunroof and wouldnt move or do anything, it was just stuck. So i turned my hazzards on then drove slowly back home. after about 30 mins playing with sunroof in my garage, hoping that i will close (then at least i can still drive my car without being scared that it will fly out from my car), finally go it to closed but now it doesnt work at all. then i have found out that from 2014 to 2018 pano sunroof is known issue and there were safety recall on some pano sunroof already on this model. i called 6 places and they told me (besides from how many they had already repaired) the holder on the sunroof rail is broken so the whole rail assy needs to be replaced. imagine if i was on a freeway going 65+ and if this would have happend and this HUGE pano sunroof flew out from my car... this is very big safety issue and that probably why 2017 (same pano sunroof) was on a recall.
There are Water intrusion that happened to other Model of Mercedes, my car have the same problem, when i bring it to the Mercedes dealer, they found a lot of water inside the trunk, but they insisted that I had accident, but there no accident that I know of.

C300 Crankcase Ventilation Valve Code P052E
Panoramic roof suddenly shattered while driving on a clear day.
The check engine light came on with the error code P052E - PCV valve failure while the car is only driven for less than 38K miles. I am worried about the quality of the car/engine.
Rear camera doesn’t work
The fault code P052E71 is logged in the fault memory of the engine control unit. Cause: Possible cause: The component or the electrical actuation at the partial load crankcase ventilation valve (Y58/2) may be faulty or might not activate initially.
I have a 2018 C class. Purchased it with 32k mikes 12/21. April 2022 I started experiencing issues. When I put my car in drive/reverse the gears shift it’s self back to neutral. When I’m stopped at a light it will take me out of drive and shift it’s self in neutral. I’ve taken my car to the Mercedes dealer for a diagnostics paid out of pocket and they were unable to find the issue. This is a major safety concern and I would like to be contacted as it is unsafe to drive and no one seems to be able to locate the issue so it can be repaired.
Damaged cords on the soft top interior trim with the following characteristics: - Cord snapped - Cord worn - Cord torn out - Cord sheathing damaged Cause: Possible high tensile stresses on the cords during the soft top sequence
Engine light is on recently on my 2018 C300. Car has 36000 miles on it. It is diagnosed as the valve for the crankcase ventilation. The actuator was blocked.
I WAS TOLD THAT THE PRESENT RECALL HAD BEEN REPAIRED. YOU STILL HAVE IT AS AN OPEN RECALL, WITHOUT A PRESENT FIX. HOW LONG DOES IT TAKE TO REMOVE A RECALL?
MERCEDES-BENZ HASN'T UPDATED THE RECALL ON MY VEHICLE
THE SUNROOF SPONTANEOUSLY EXPLODED OUT OF NO WHERE. SOUNDED LIKE A SHOTGUN BLAST.
