POWER TRAIN, ENGINE
Car check engine light came on with only 62,000 miles. Diagnosed as code P052E, the issue is the positive crankcase ventilation valve being faulty. Regular oil changes and maintenance was done. I see multiple complaints with this issue, why is this not recalled? It is very expensive to have fixed.

My engine light keeps coming on and off on my 2017 C300 4matic coupe. I got the problem diagnosed in March 2023. Benz said I had a faulty solenoid valve and that I would need to replace the crank case ventilation assembly. That is $3000. My friend has a C300 sedan and they replaced his under the extended warranty that came out on August 2023 for the crankcase. I have the same exact issue but they said my VIN doesn’t populate so they cannot do anything. This is the 2nd faulty crank case in my car, it was replaced by warranty in 2019. I don’t drive that much I have 47K miles on the car. They refuse to cover the faulty part.

My gas door has fell off 3 times exposing my gas cap. I got it replaced twice. It fell off on the highway and the other times I was just doing gas and it fell off into my hand. No excessive force. I didn’t want to pay again to repair it so I just taped it.

STRUCTURE:BODY
I currently have a 2017 Mercedes C300. The panel between the windshield and main panel of the panoramic roof (above the driver) is deteriorating and doesn’t not seem to be fully attached anymore. I had the exact same model but a year older in the past and this same part deteriorated and was subject to recall. I believe there is not only an issue with the part itself, but how Mercedes has bonded these parts to the roof.
