2016 MERCEDES-BENZ C300 Complaints

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 .

I have a 2016 C300 that was diagnosed with a severe brake booster issue. Last week, I had to brake hard while traveling 65 mph on a highway and they failed; luckily I was able to avoid catastrophe by maneuvering around the obstacle. I researched to see if this was a known issue and learned that some Mercedes models between 2008-2012 had recalls due to brake booster corrosion issues, but Mercedes might have a worse issue than just a few models prior to 2012, based on my experience!

At approximately 65K miles, my PCV valve is bad and needs to be replaced at a cost of $1600. I saw lots of customer complaints for the same issue online, I think Mercedes should cover this item under recall.

The contact owns a 2016 Mercedes-Benz C300. The contact stated that upon purchasing the vehicle, the driver's side sunroof corner was slightly raised. The contact stated while driving at 40 MPH, she heard the panoramic sunroof glass sliding back and forth. The contact stated that she held the sunroof glass while driving. The contact stated that the failure had been reoccurring. Additionally, the contact stated while attempting to open the sunroof, it slightly opened and the force itself closed. The dealer was not notified of the failure. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 73,000.

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.

The contact owns a 2016 Mercedes-Benz C300. The contact stated while driving 45-60 MPH, the vehicle began to stall. The contact depressed the accelerator pedal several times but the vehicle failed to respond. The vehicle stalled. The contact was able to veer to the side of the road. The contact was able to restart the vehicle. The check engine warning light and several unknown warning lights were illuminated. The vehicle was towed to the contact’s residence. The vehicle was then towed to the local dealer where it was diagnosed that the fuel pump and fuel tank needed to be replaced. The vehicle was being repaired.

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.
