This is a known problem with The Mercedes cars from 2015 through 2018. The Service advisor said this is a know issue with this year, I asked can you do it for free because it is a Merc issue. He said he cannot do it. The cost for this repair is $2500 in Mercedes show room. These should be recalled and repair it for free for the customers.

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 i…
TL* THE CONTACT OWNS A 2016 MERCEDES-BENZ C350E. THE CONTACT STATED THAT THE VEHICLE'S AVERAGE MPG RANGED BETWEEN 25 TO 34 MPH. IN ADDITION, THE VEHICLE HAD TO BE RECHARGED EVERY 11 MILES TO KEEP THE ELECTRIC CHARGE GOING ASSOCIATED WITH THE MPG. THE MANUFACTURER INDICATED 51 MPG ON THE STICKER AND IN THE OWNER'S MANUAL. THE CONTACT WAS WAITING FOR THE MANUFACTURER TO PROVIDE FURTHER INFORMATION. THE FAILURE MILEAGE WAS NOT AVAILABLE.

This is a plug-in hybrid car and twice in the last two weeks, the car while in motion on the road, has randomly turned off the engine and lost power. The gas pedal is unresponsive and all the alarms on screen flash and I have to coast to a stop. Most recently it was on a busy road and I barely missed being rear-ended. This is an unsafe situation and has happened twice and the only thing which I can do is come to complete stop, turn off the car and restart it and the problem goes away.
