Got a check engine light at 72,047 miles. Looked up the code at autozone and it is a P052E. After googling this code, discovered this is an EXTREMELY common issue with 2015 & 2016 c and cla class mercedes. (see here https://mbworld.org/forums/c-class-w205/739851-check-engine-code-p052e-2.html). This is a ventilation issue with the Positive Crankcase Ventilation Regulator Valve Performance. This is a VERY expensive fix despite seemingly being a VERY common issue at this mileage for these cars. This seems to be a defective part that Mercedes installed at the factory as no one ever gets this message after having their original valve replaced. Without the fix, this will cause oil to become sludgy and perhaps cause engine to seize or smoke.

I was driving my cla in the rain on the 405N in irvine, ca at about 4pm to go to my new place of employment for onboarding. I was going approximately 25-30mph because of the weather and traffic it was very slow. I put my blinker on to merge over into the second lane and my car beeped and automatically went into neutral. I couldn't do anything, it felt like my steering locked up and I could only slightly move the wheel, my blind spot assist was inoperable, my dashboard lit up every light/warning sign it could and I could not switch gears. I had to slowly roll two lanes over into the emergency lane while it was pouring rain. I almost got rear ended because of how slow my vehicle was moving over. I did not turn the vehicle off because I wasn't sure if I would be able to restart it. I waited on the side of the freeway for 2 hours to get towed to the nearest dealership which was newport beach fletcher jones. About a week prior to this I had my battery changed at Mercedes because it completely died and wouldn't hold a charge. When I got to the vehicle I was informed that 2-3 other cla's came in the same day, with the same problem.
