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.

I have a 2018 Mercedes Benz c63 amg which I purchased new in 2018. I have only 61,230 miles yesterday 11/10/2025 it started making a loud noise coming from the right rear. I drove to the Mercedes dealership in Belmont,Ca the technician mechanic told me that the rear differential was bad and need to be replace. Cost $7,000.

Owners were advised to contact their local dealerships for repairs or replacements as necessary.

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.

I was driving around my neighborhood one day with my panoramic sunroof open and at the red light i wanted to close the sunroof (california summer sun is no joke) and it made this really big 'THUMP' noise, thought the sunroof glass cracked. After the big THUMP noise, the sunroof wouldnt close and this is after the light turned green so i am driving slowly because there was rattling noise coming from the sunroof and didnt want the sunroof to fly out from the car. So i had to pull over and try to figure out if its okay to drive with stuck sunroof with it rattling noise. after that i tried to close and open the sunroof and wouldnt move or do anything, it was just stuck. So i turned my hazzards on then drove slowly back home. after about 30 mins playing with sunroof in my garage, hoping that i will close (then at least i can still drive my car without being scared that it will fly out from my car), finally go it to closed but now it doesnt work at all. then i have found out that from 2014 to 2018 pano sunroof is known issue and there were safety recall on some pano sunroof already on this model. i called 6 places and they told me (besides from how many they had already repaired) the holder on the sunroof rail is broken so the whole rail assy needs to be replaced. imagine if i was on a freeway going 65+ and if this would have happend and this HUGE pano sunroof flew out from my car... this is very big safety issue and that probably why 2017 (same pano sunroof) was on a 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 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.

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!!
