Crankcase ventilation valve. PCV valve has failed causing check engine light. Very common issue on this model according to my research. The dealer does not have this product in stock to facilitate a repair and no support to find the part. Very difficult when trying to pass an emissions test and this is the last thing holding that back.
My car is a 2015 Mercedes Benz, I bought it at the agency in 2022. When I tested the vehicle at the agency, I noticed the steering was a little hard. I asked the sales person and he told me it was normal. Then, after 1 year and 5 months, it was on its way. I went to work and the steering wheel jammed and it wouldn't cross and the car turned off then it didn't want to start and it said the following on the dashboard power stering see operator manual
Positive crankcase ventilation regulator valve failing and code P052E comes up. Mercedes Benz said this is a problem with all 2015 c300 and should be recalled
The panoramic sunroof is faulty. Doing a simple search online showed that this is a common problem amongst my vehicle model where parts are loose or misinstalled and it is a safety concern in a potential accident or rollover. My dealer is now looking into it and it is also an excessive out-of-pocket cost to make the vehicle safer. Something I do not expect from a high-end vehicle manufacturer. I identified this due to the rattling sound in the ceiling/sunroof.
Front drive shaft on 2015 Mercedes Benz C-300 severed from u-joint(s) on highway, causing catastrophic failure of components and significant damage to front exhaust, catalytic converter, and heat shields. Damaged observed on transmission and/or engine block. The approximate cost to repair was $6,500 in parts and labor. Failure of subject component(s) resulted in loss of some control and acceleration. Prior to failure, observed increasing vibration from center of vehicle while exceeding 65 mph but no more than 80 on highway. Audible clunking noise when shifting from "park" or "neutral" to "drive." No warning lamps and/or messages regarding failed component(s). Vehicle has not been inspected by manufacturer, police, and/or insurance representatives. Dealer provided inspection and findings.
After getting gas my check engine came on steady. Stayed on until cleared. After getting gas a 2nd time check engine light came on again, stayed on, but went out. Then after getting gas a 3rd time, check engine light came on again. Checked by a local Mercedes shop, code showed intake line oil separator bad. Owned this car for 7 years, never had an issue like this. 50,516 miles currently. Quote for repair is high, over $1000 dollars. All episodes of check engine light have occurred in a 4 week time frame.

I took my vehicle to the dealership to have recall worked on (top sunroof panel) apparently they refused to work on it because my sunroof is not working. I received a letter after i financed the vehicle stating that there was a recall so to take it in to the dealership and if sunroof needed to be fixed it would. Long story short, back in July the panel detached from my vehicle while i was on the freeway. Thankfully I didn-??t cause an accident but I would like some help so the dealership can fix the recall.
Crankcase ventilation (PCV system), on C300 and GLC 300 is a know issue with this model care fro 2015 to 2021, yet Mercedes Benz manufacture the cars the same way with addressing in order to over charge customers and claim it-??s a wear and tear part
This is in regard to my 2015 Mercedes Benz C300 4 matic. I was driving at the normal speed of approximately 65mph on the highway. When out of nowhere, I heard a very loud wind noise. I was terrified since I was alone and was not sure why or what happened. I pulled over and noticed the front panel of my Sunroof glass was missing. I was very disappointed as I have always believed that MB has had a strong reputation for their cars. I circled back around and was able to find the part on the side of the highway, but it was broken. I have had heavy-duty tape covering the space so water cannot get in. I contacted my local MB repair shop and told me the part would be $1100 and labor would be additional.
The crankcase ventilation valve has gone out on my car. This is a continual problem with these vehicles at low mileage. Mercedes Benz should recall the part for repair as they stated it could damage the engine.
