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.
