Check engine light comes on, Error Code P052E, after a lot of research, this is a known defective part by Benz. Huge safety issue not addressed by them. Very costly to fix for a customer. There is a new and improved replacement part from Benz indicating they are aware of the faulty old parts that are currently in those cars but yet they have failed to do a recall.

My vehicle only had 31,000 miles and I experienced engine failure. I bought a new engine for 16, 500. 00 dollars. Mercedes Benz did nothing. I almost got in to several accidents because the engine completely stop on the interstate. Almost got hit by several cars. This is unacceptable.

Rearview Camera is not displayed when the vehicle is placed in reverse. The display shows a black screen. A Recall Notice has been published for other vehicles of the same year, make, and model. The failure of the Rearview Camera results in safety risks during normal use of the vehicle.

I have noticed the driver seat belt not retracting after usage. Upon looking online I saw a post about a recall. Called local Benz dealership and BenzUSA customer service both said my Vin is not part of the specified recall.

In August 2024, a Mercedes-Benz dealership in Salisbury, MD installed the wrong type of rear tires on my vehicle. I was not informed they were mismatched or inappropriate for my vehicle. I later drove across the country with my infant child in the backseat, believing the tires were new and safe. On April 17, 2025, a certified tire shop in Texas (Discount Tire) inspected the tires and told me they were not suitable for my car and were already too old to be considered new — despite having been installed just 8 months earlier. They refused to buy them back or reinstall them due to the age and mismatch. Additionally, the dealership had earlier failed to correctly diagnose my ABS system, citing water damage but doing no further inspection. They also missed a major coolant leak and water pump failure, despite charging me for multiple diagnostics. Their negligence in both diagnosis and tire installation directly put me and my child at serious safety risk, especially while traveling long distance at highway speeds.

I recently purchased a 2018 Mercedes C300 and I noticed the rear view camera will not show an image. It mechanically will open and all other cameras are fully functional but the image will not show instead I see a icon of a camera in a red crossed circle. When doing VIN serch on my vehicle I don't see any open recalls. However, I noticed that NHTSA campaign number 22V232000 has recalled this exact issue. Although the report 573 says for it applying to 2019 models but with a production date between 2017 to 2021 vehicles applying. So I believe this recall should also apply to my vehicle.

The contact owns a 2018 Mercedes-Benz C300. The contact stated that while the vehicle was parked inside the garage, there was a strong fuel odor inside the garage. The contact stated that there was fuel leaking from the vehicle. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 52,300.

The engine light is on with only 35000 miles. Upon using an OBD2 scanner, error code P052e positive crankcase ventilation(PCV) malfunction was detected. It's a problem that I researched and noticed a lot of people having the same issue. I was told that this can cause the car to stall or shut down? This causes serious risk and safety issues to drivers, passengers, and pedestrians. With so many complains about this problem, I believe the manufacturer and dealers should take responsibility before tragedies happen.

The contact owns a 2018 Mercedes-Benz C300. The contact stated that while driving at an undisclosed speed, the rear window glass which was not properly bonded had become loosened. The vehicle was not diagnosed or repaired. The VIN was not included in NHTSA Campaign Number: 18V608000 (VISIBILITY). The manufacturer was not notified of the failure. The failure mileage was 50,000.

Problem a recall was done on certain Mercedes vehicles where the front panel of the roof between the panoramic sunroof and windshield has defects in gluing or bonding agent from the manufacture. I believe my vehicle is showing possible premature bonding agent issues below the surface of panel. Where the manufacture bonding glue is causing interior flaking and cracking and lifting from the stress of the wrong/incorrect specified bonding material not used during the manufacturing process . I am afraid that while driving my vehicle at highway speed has the opportunity / potential for my panel to eventually break off and cause damage of flying panel pieces to harm myself or other vehicles traveling on the road. I believe the wrong bonding material is also causing other issues with the panel and the workmanship material used. My vehicle falls under the year, make, W222 and I am already seeing issues with my panel that by being proactive on my vehicle then reactive. I don’t want to wait for my panel to fly off when early detection and rectification is the safest way/option. My second concern is that there has already been changing dates on this recall information sent out in 2017, 2019 and now 2021. I am worried!!

The contact owns a 2018 Mercedes-Benz C300. While driving at various speeds, the contact could hear an abnormal sound from the transmission. The vehicle was taken to a local independent mechanic where it was diagnosed that the rack and pinion needed to be replaced. The vehicle was not repaired. The vehicle was then taken to a local dealer for diagnosis, but the failure could not be replicated. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 57,000.

I need the Crankcase ventilation valve replaced and have heard many complaints about this repair.

The day after I purchased my c300, the engine light popped on. I went back to dealer and they said it was a recall because of a crank case (PCV). I was upset because they never said anything about it. This was April of 2024. Note:(This Dealer was not Ray Catina’s of Edison). I went to Ray Catina’s in Edison for them to inspect car and I have been calling because I was told it was a national recall and it was on back order and should be here in June. It is now almost August and I called on the 23rd of July and received a call from Ray Catena on the 24th for them to tell me that “they were told that the new plan from Mercedes is to bring my car in and they will clear code. That’s what they are told to do.” To me, this is NOT fixing the issue. I am a little aggravated because I bought my car on [XXX] and have NOT been able to feel good because not sure what ramifications will come with me driving my car with this issue. I was told that driving with this engine light on and code that it will not harm my car. They now say Mercedes was told to reset the code and that will resolve issue? I believe this is a band aid not a fix!!! I’m a little upset. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
