It would have to make sense for me on when a character being OOC is crucial to the plot. "House Music" for instance makes sense, because Luna was wanting to impress her idol as well as possibly acquiring fame. However, that causes her to devolve into a controlling jerk, who does learn her lesson at the end.

The issue with that one scene in "Garage Banned" is it serves no purpose in the episode. Sure, you could probably say that it was meant to show that the siblings need Lori to maintain order, but it's executed poorly. If it was meant to be funny, it isn't either; really both Luna and Luan look like insufferable brats in that episode.
