One problem related to engine burning oil has been reported for the 2015 Subaru Impreza Wrx. The most recently reported issues are listed below.
Vehicle is burning oil, oil came out through where the dip-stick is placed. Found oil on the exhaust tips. Mass air flow sensor is malfunctioning. Requires new coils and spark plugs even though I have already replaced them. Required a new battery, however, replacing the battery did not keep the vehicle from turning off by itself. O2 sensor, bank 1 sensor 2, is also malfunctioning.
