There was a bulletin for an updated valve cover and a deflector in the oil pan but I don't think it applies to 2015.

Is this bulletin for 2012? Mine is eating oil. Valley cover breathting issue maybe. You know number of TSB?

built prior to 2/1/11 already have the updated valve cover and doesn't need the AFM shield. If there's no oil leaks it's likely stuck piston rings. There is a cleaning procedure to free them up but it may need pistons if it doesn't work.
