Owner reports filed with NHTSA, as written (personal details removed). Complaints are not verified by NHTSA.

Engine · reported Aug 27, 2023

Check engine light came on, a day after purchasing from dealer. Mileage at 55k. Check engine light code was p052e71, confirmed from 2 auto repairers. One was Mercedes Benz who quoted me $3900 to repair. In the Mercedes Benz booklet warranty says emission related repairs are covered for 15 years/150k miles for hybrid vehicles.

Unknown or Other · reported May 10, 2023

Car had 69,300 miles (5 3/4 years old) at time of service on 4/18/2023. The check engine light came on the day before. Dealer performed diagnostic- stated it was the Crank Case Ventilation that needed to be replaced. I was charged $2107.00 $1710.00 for labor, $397.00 for parts. I have owned 2 other mercedes well into the 100,000 mile ranges- no problems similar to this. It seems to just be a C300 issue- my car is a C350e. It has been serviced at the dealer every year and is garaged and well taken care of. I read online that c300 have this issue- and would like to report mine as well.

Engine · reported Apr 4, 2023

I have a 2017 C350E with 69K miles. Dealer wants $2900 to fix the Crankcase Ventilation Valve. The part that needs to be replaced costs about $600 with lot of labor time involved (~$2500).

The C350E has a 15 year emissions control warranty in California that is supposed to cover "all" emissions control related parts, but Mercedes Benz USA doesn't seem to think this is part of the emission control system. I have done some research and it appears that "crankcase ventilation" is a necessary function of the engine because "blow-by" fumes would build up in the…

Electrical System · at 10 miles · reported Mar 27, 2021
