NHTSA Complaint #11548516 — 2015 MERCEDES-BENZ C300

My check engine light came on recently on my 2015 C300 4matic. Car has 66500 miles on it. The code P052E71 was diagnosed - The valve for the crankcase ventilation has a malfunction. The actuator was blocked. This problems seems to be occurring to a lot of similar cars from Mercedes and some of them have reported that this issue keeps coming back. The dealership and other auto body shops say it's going to cost around $1500-$2000, considering how it's a tedious job to do and involves multiple hours of labor. The dealer won't repair it as part of warranty. This definitely seems to be an engine issue with the car and has nothing to do with how we drive. Cars not older than a couple years are starting to see this issue. There needs to be a recall for this and have Mercedes does something about it. Why are the consumers having to spend money to have the same repairs done for a bad design, parts and engine being provided by Mercedes.
