My car's stationary roof panel (part no. 205-780-00-22) that's located between the windshield and the panoramic sunroof started to come off while driving. The panel started to flick off and I had to tape it temporarily, so it doesn't fly off when driving. It looks like the adhesive holding the panel gave out on the driver-??s side. Panel was previously replaced at Mercedes Benz of Tysons Corner.

while driving on a highway a part of my roof panoramic fell risking my life and other people's life, I then sent an email to Mercedes Benz and they told me that this part is a subject of a recall. I took the car for two days and they told me that the part is not available for the moment and they need to order it from Germany with no ETA but at least 2 weeks. I asked them if I can safely drive without that part and they said it is ok. Yesterday while driving under light rain, water went in the car through the roof and through the missing part place onto the dashboard. And suddenly the panoramic roof opened alone and did not want to close while I was driving on the highway under the rain. I had to leave my car with an open roof. This roof issue is a repercussion of that item subject of the recall in addition to telling me that driving was safe without that part and turned out to be unsafe. I sent Mercedes Benz an email asking to fix all this mess for free and still waiting for an answer! Much appreciated, Ali

Glass piece in front of sunroof of panorama roof flew detached and flew off while driving. I was driving on freeway about 80 miles per hour on a straight stretch. It was not hit by anything. Just the wind. Cost to repair $2178 at mb authorized dealer.

On October 15, 2019 and on July 1, 2020 the glass panel which is located in front of the panoramic sunroof blew off the car while driving on the highway. This piece of glass does not move and became a dangerous projectile endangering other vehicles. I would guess the glue is not bonding properly

In addition to a strong, noxious, moldy odor, vehicle's front windshield fogs over so totally that it becomes dangerous in highway driving. The HVAC/climate-control system's defroster is unable to clear more than the bottom few inches of the windshield: The only way I can see through it is to wipe away the fog with my hand. This happens when the vehicle is in motion but persists when it is stationary. This happens in almost any weather, but especially if there is moisture in the air(fog, rain).

I had been driving for 5-7 minutes I was going down a slight incline on a rural road and took a right hand turn. The driver's door opened and a red warning light came up on the dash. I immediately applied the brakes to stop my vehicle and looked at the door. I noticed that the door lock button was still down. I was able to pull the door closed. My son was in the passenger seat and witnessed this, we were shocked to say the least. Carriage house of new london 488 colman street, new london ct 06320 ph# 860-447-3361 picked up my car and ran diagnostics they said they found nothing wrong. The invoice number associated with that service call is 79121

The tires supplied on this car are unsuitable for intended use. Low profile tires are easily damaged by potholes (we live in Chicago) and without constant inspection for "bubbles" present a hazard. This car is two years old with 8800 miles on it and is on it's 4th front tire. In as this is how the car comes, and the dealer as acknowledged this is a common problem they have clearly sold tires that are in the long run not safe.

I was driving down the freeway at approximately 65 mph and the panoramic sunroof on my Mercedes C300 exploded. I say "exploded" because nothing struck the glass and most of the glass blew out and off the car, not in. The sunroof was closed at the time, so there was no wind pressure. After I stopped, you can even see where the glass remaining is sticking up, not down. The shade was open so glass did fall into my car, cutting my arm. If kids or others were in the car, it would likely have cut them or could have resulted in glass dust in their eyes, etc. It also could have caused an accident by scaring me but also since much of it blew off my car, it put the cars behind me in danger and could have caused them to crash. Mercedes has not taken responsibility of this yet, but I have brought this to their attention. The vehicle was only a little over 1 year old and only about 17,000 miles on it. No way should this have happened. I have more pictures, if you want them.
