on 7/17/21 the piece of the top of the car right from the from window leading to sunroof came undone and flew off while on highway. vehicle was repaired a month later at body shop. this was out of pocket due to not wanting to claim on my insurance due to deductible. This piece flew off at a high velocity with no warning and couldve caused a accident. There was no indication of any issues no lights no warnings signs. There was a loud noise like a brick or large object falling on top which then I heard a lot of air. Recently again in October 5 I was driving on the highway and debris hit my sun roof, my window was shaking and I went to the body shop. in the brief drive there some 10 miles the same plastic part repaired was lifted and coming off. on this occasion I used my Insurance. On 03/2/22, another event in which the plastic portion between front window and rooftop flew off while driving 60mph on the highway.

The panoramic sunroof of the C300 is held in plastic hooks that break, even with normal use. So, that leaves the panoramic roof to fly off the vehicle on the highway. I have not opened my roof in three years because I am afraid it might not hold up. Looking at the MB owners' forum, it seems to be a pretty common issue that these plastic hooks break, and then the panoramic roof either doesn't close all the way, stay up to let the air come underneath it to introduce the risk of it flying away, or become really flappy when driving with open roof.

On July the 8th I was driver on interstate highway 65south in Birmingham Alabama in my 2015 Mercedes c 300 when there was a loud thump which startled me and almost caused an accident what happened is the roof panel between the windshield and sunroof flew off it caused damage to my vehicle and almost an accident now when I contacted Mercedes they say that it is a recall out for this problem but they do not have a time as to when this can be fixed this will be a problem because now I am not able to drive my vehicle because there is a gape between the windshield and the roof where water and anything else will get into the vehicle this is terrible now I am without a car for who knows how long.

Driving down the interstate and half of the stationary roof panel dislodged. Luckily no accidents occurred due to the malfunction. The other half is still loosely attached and I am worried it could cause an accident if it detaches. I have emailed and called headquarters as well as my local dealership and no one has the ability to fix the problem and cannot confirm if I choose to pay out of pocket, that I will be reimbursed. There is a recall and it-??s #21V197. At this point I want some sort of solution so I can ensure the safety of myself and those driving around me.

My daughter was driving at freeway speeds, when she heard, what we now know, is a portion of the sunroof panel flapping and break off. There was no warning, no instrument indication, and assume the broken part was a safety hazard to vehicles following. We took her vehicle to Fletcher Jones Mercedes in Newport Beach, but they're hesitating about repairing or reimbursing costs, due to the pending nature of the NHTSA Recall #21V197.

While driving my 2015 Mercedes Benz C300 4matic with panoramic roof one day on rte 9 in hyde park NY, a 2 lane state road I was traveling at 40 mph, I suddenly heard more air than usual and then seconds later a loud flapping noise on roof. I pulled over immediately only to find the stationary roof panel all the way forward on the roof, (directly in front of glass portion of the pano roof) became loose on one side and flapped open with wind when in motion. I used 3 quarters between windshield and said panel to hold it from popping up while driving and drove immediately to a body shop. Tbey inspected it and determined it was held down with black epoxy similar to what is used to install glass such as windshields. They added some epoxy and taped down the piece for me. Approximately one week later I was traveling on the same road at about 30mph and suddenly all within like 2 seconds heard loud wind, then flapping, then saw the roof piece fly off swing in front off windshield it was still attached to a rubber gasket, then up in the air and back down and smacked the side of drivers door before breaking free and flying down the road behind me. Luckily it did not strike any cars or people as it briefly held on to the gasket attached. I immediately stopped and was able to retrieve it, broken into 2 pieces. Some online research found this has been a very common problem with many, many people who posted all ovwr the internet on facebook and several other sites. I then found the exact same problem, and part was recalled by Mercedes for 10S of thousands if cars, but the recall did not include my year (but did include my model for other years). This is very obviously the same exact problem and should be covered for all years by Mercedes. I called and after a lengthy phone call with Mercedes Benz I got nowhere. The agent for mb refused to even admit it was a recall, and was rude.

The vehicle was thankfully noy in mption when my panarama sunroof and the shades failed. The shades I understand its not a safety problem, but the sunroof not being able to hold in place as it opens is different. When the sunroof opened, the rear of the roof was not in place and shaky. When I tried to close, it had not locked itself right back in place, where I had to take it to a mechanic just to have it shut to avoid the rainstorm yesterday. I recently did some research and read through some articles, had a friend of mine take a look at it and it seems to be very similar, almost the same as the recall they have done on other year make for the panarama roof.

My panarama sunroof just fail and almost collapse on me. My car is 5 years old. I was driving and it appear the glass was coming out. The vehicle was stationary. I'm afraid that the glass will pop out and fall on me. This is serious. It could harm me if it falls on me.

I was driving on 02/13/2020, about to cross the Arkansas/Tennessee bridge when my sunroof exploded without an explanation. The entire panoramic sunroof shattered. It was the most frightening thing I have ever experience. If my sunroof screen had been open, all of the glass would have fallen on my head and in my eyes. Called the mb dealer for help, they weren't willing to help and suggested that I file it with my own insurance company. This is a defect of mb!!

Speakers randomly stop working - sometimes for a few hours and other times for up to 5 days. When speakers are not working, this means the stereo, navigation, bluetooth calls, and emergency calls are inaccessible. This is a problem for many drivers please click on the link below.

Entertainment unit does not work at all. Happened out of nowhere one day turned on the car and it was frozen. Back up camera 9/10 times does not work and when it does it turns on after you have backed up and are already going forward. Unit freezes unable to change or do anything to the unit itself. Occasionally a blue screen pops up for 1-2 seconds and goes to the initial start up screen for a while. I went to my local dealership and the admitted of hearing about this problem from other owners with the same issue and said there was nothing that could be done cause they have no idea how to fix it, I mean that's absurd.

There is a serious problem with the vehicle mentioned above. The entertainment system and the rear camera do not work. This is a serious safety concern regarding the rear camera. The C-class is designed in such way that you depend on the camera when reversing and it is very difficult to see the rear view when backing and looking from all angles. I called your hq in Maryland for assistance, they were unaware of potential reported problems. Their best answer was to call the dealership. The following day, I received a phone call from new country motor cars Mercedes Benz of hartford, ct stating that they have not heard of this problem and its very unlikely that it was associated with the recent recall regarding this vehicle. Upon arrival, and retelling my story to the service advisor helder crespo, he told me that their received numerous complaints about this particular vehicle make and that other customers are affected by this similar problem. It been three weeks, I have not heard anything from mb or dealership. I am quiet appalled by this matter and shocked by the improper communication from mb to their loyal customers. Is this 'the best of nothing' customer relation?! I am extremely dissatisfied how this matter is being handled and that not even one single person who knew about this issue did not even apologize for the inconveniences that this had cased me.
