A little confused with the stayed symptoms, a dropped valve usually causes catastrophic damage. Evidently the valve just suspended in the guide somehow. Perhaps you could let us know what the dealer says about it.

Pentastars describes the failure it sounds like the OP has experienced, as it affects cylinder #2 valve seat(s):

It now appears that a number of 2013 model-year cars and trucks were also affected, indicating perhaps a second change.
