2-1 shift or 1-2 shift on slow take off. My 2010 with 170k miles on it has done that for as long as I remember. I wouldn't worry about it personally.
I did have my tranny reflashed by a tech at the dealer after experiencing the violent downshift from 6th gear when stepping on the gas. Reflash worked like a charm and it's been great since.
