2017 MERCEDES-BENZ C 300 Complaints

Factory AMG rims. 3 of the 4 rims have cracked. The last rim cracked with brand new tires. So it is not a tire issue. I find it unbelievable looking online how may others have had this problem with AMG rims. Does not seem acceptable.

Check engine light came up for a PCV valve error. Car was driving fine with no recent changes and the repair is going to cost over 2000$.

My engine light comes on intermittently for days or weeks at a time. Code is P052E indicating an issue with the PCV valve. I'm waiting to replace the part.

P520E code which is caused by a crankcase ventilation issue. The fix costs upwards of $2000. It seems to be a common issue with Mercedes vehicles with 4 cylinder turbos and should be a recall on this system.

The vehicles panoramic sunroof does not close fully. There is a recall for certain Mercedes-Benz 2015 - 2020 C300 vehicles, my car is a 2017 C300, but for some reason my vehicle is not part of the recall. The recall number is 21V197000.

Piston one issue. I bought this car from an auction and according to the record on the car the previous owner had problem with piston one and low compression in that piston. After performing some research it looks like Mercedes’ Benz c300 m274 is riddles with this issue. It’s all over the internet and I don’t know why Mercedes is not taking responsibity for this. This car has less than 70000 miles and the engine is locked from the cylinder. Thank you
