I bought my 2016 merecedes Benz c 300 4 matic with an engine light on. I took it the dealership and is the positive crankshaft failed. The crankshaft could reduce power on car. At 73000 mile the crankshaft should have not failed.
the Burl wood trim panel on the interior doors are deteriorating, the drivers side panel is deteriorating to the point that it looks like acid is eating away at the material there is red markings showing.. i find this could be a safety hazard as it could eat away at the door itself. i have pictures of evidence. there was a recall on Mercedes E class during the same years i purchased my car, my car is the C-class which was not part of the recall, but falls into the same category as time frame of purchase. Mercedes told me to contact you. i look forward to your response as this is a safety concern thank you
I took my 2016 Benz through a car wash and realized the glass in front of my sunroof that is part of windshield is loose. I can hear wind coming through when I drive. This is driving hazard.
I bought my 2016 merecedes benz c300 4 matic with the engine light on.when I did a diagnostic on it came back to a po52e is bad. It had 73000 on it when I bought. Now I sit at 77000 miles with the bad part.
The check engine light came on. I pulled the code and it was P052E, and requires the replacement of the crankcase ventilation system. I am told that this happens on virtually all C300s and (and maybe the GLC300 also). I think this should be recalled.
Check engine light came in so I took it to a local auto shop. They ran the diagnostics and the code that appeared was P052E(Positive Crankcase Ventilation Regulation Valve Performance).
I was moving my car from one parking space to another space in front of my house. As I was pulling into the new space, I stopped to check the position of my car. As I lifted my foot off the brake, the car unexpectedly started to lurch forward. When I released the brake pedal, the car suddenly accelerated and proceeded to jump the curb and run into the front of my house. Luckily, no one was injured. There was some damage to the exterior of my house. I have reported this issue to the car manufacturer, Mercedes Benz. In response, they have opened a case to research it further.
Check Engine light came on. Upon running the scan from three different reputed repair shops, they show same P052e Positive Crankcase ventilation valve replace message. It first came two months back, reset the code but it still came up.
I was driving my 2016 MB C300 on a clear sunny day (approx 85 degrees outside) going around 50 mph when out of nowhere my pano sunroof exploded (extremely terrifying sound might I add!)! I never open my sunroof and it did not have any chips or cracks at all so there is no explanation. Almost the entire sunroof shattered! Mind you I was driving on an open road (no trees, overpasses, bridges, etc). No cars in front of me and closest car was around 1/4 behind me. Shards of glass fell on top of me and went all over the interior of my car. I almost drove off the road and could have gotten glass in my eyes! After inspecting, it almost appears as if the glass exploded outwards. This is a major safety concern and needs to be addressed ASAP by Mercedes Benz before someone gets killed!

The system that failed is the rear backup camera. The dash screen becomes black after initiating the car into reverse. The screen also glitches green and other times black. I have also received a -??no camera-?? circle behind my rear backup camera with the 360 degree camera. I cannot use my rear backup camera as designed because of the issue. Even putting the vehicle back in park and then back to reverse does not remove the issue. This has happened on multiple occasions just this week. This started this week in my car. 1/21/2022 was the first time it happened. It has happened every day since and multiple times. I have photos and videos of the issue. The photos are attached to this report of the safety issue. I am unable to upload the video but can send upon request to an email.
Mercedes-Benz comes with ECO Start/Stop feature. This feature automatically activates when you start the vehicle and have your seat belt fastened with the door closed. When this function is activated, your vehicle-??s engine will shut off when you are at a complete stop, like at a stoplight or in standstill traffic. Once it-??s time to start moving again, the vehicle-??s engine will automatically restart as soon as you lift your foot off the brake. Randomly experiencing an issue with this feature, vehicle will not restart or it will shutdown in the middle of the road, on the busy road or freeway, it is very unsafe or dangerous. In last two years, we experienced this issue for at least 10 times, at least 5 times vehicle was towed to Mercedes Benz service center in Pleasanton, CA. They replaced the battery, starter, relay but issue still exists and service center also do not have any clue on how to resolve this issue. Reported this issue to Mercedes Benz Customer Support but response has not been favorable. I am not the only one facing this issue, several people reported this issue on online blogs, online channels and discussion boards. Mercedes Benz is ignoring the issue and not serious on addressing it. I request NTSB to investigate this issue, it is risky and dangerous. I personally had couple of close calls with other vehicles rear ending, and I am sure others must have found in this situation. Appreciate your help.
