2016 Mercedes-Benz Metris Engine Problems

“2016 Metris Engine M274 Check engine light, P052E71 Crankcase ventilation valve- Oil leakage- safety is compromised as this damage causes engine failure. The dealer has confirmed multiple oil leaks and other parts and service is required at extensive cost to me. This is the same damage and failure that passenger models with the M274 engine have an extended warranty available to them- my PASSENGER Metris with the exact same engine is excluded from this extended warranty.”

“The check engine light came on and the code reads PO52e. Mercedes has a Intake Line Assembly Extended Emissions Warranty (Code P052E) up to 150,000 miles. They’ve admitted this was a problem with this engine but only covers 3 other vehicles with the identical platform, & excluded the Mercedes Metris”

“Code P052E-71 Valve for crankcase ventilation has a malfunction Code P06DA-00 Actuation of the valve in the combustion engine has an electrical fault or open circuit. These codes have been reported on too many times on forums to not have these issues recalled and fixed and paid for by Mercedes. This expensive problem should not have occurred with such little mileage and have to be fixed by the consumer”

“The Crankcase ventilation valve called (Crankcase Rebreather)comes with a defect making engine light to come on after about an average of 50.000 miles, with a code p052e, preventing passing state vehicle inspection. Feedback from many Metris ownership highlights exact same challenge with engine light turned on at all times. But dealership is charging up to 3.000 dollars to remove their own faulty designed part.”

“position sensor for intake camshaft had a malfunction. Position of intake camshaft implausible. Intake camshaft pick up wheel was not in sync with timing. Antique camshaft was out of sync by 180°. This caused a loss of power and engine functionality while underway.”
