Yes, Mayo problem is widely known. It is also widely known that, assuming the CCV system is not clogged--that would be covered under warranty, the simple solution is take a drive once in a while that is long enough that the engine gets to operating temp for a period of time. I would expect the dealer to advise the owner to do so when the see it during the oil change. I think it is a reach that the dealer would attempt, let alone be successful, deeming mayo condition as a violation of warranty. It's far more likely they would install the cold weather CCV system and advise the preventative measure mentioned above.
Have you heard of a voided warranty due to the mayo issue. I haven't.
