Check engine code PO52E - Positive Crankcase Ventilation regulator valve performance. Needs to be recalled

Oct 28, 2024

I am driving around 55K miles in this car, and my check engine light comes up. I head to a local place to get a code check. The guy looks it up and tells me this is pretty much with EVERY Mercedes CLA around that mile point.. So, I look up on reddit and other forums, and it's exactly what he said. Pretty much the PCV valve is faulty and costs around $1800-2500 to fix after 50-60K miles which causes emission problems and other safety concerns if not taken care of. It makes no sense how this is not a recall. Of what I read, Mercedes knows all about this and has done nothing, just leaving the drivers to take care of a problem that they did nothing to cause. I am not sure if this is for the NHTSA or what, but it is kind of unacceptable.
