She probably would have forseen how damaging it would have been to her and her parents already strained relationship to hex them without asking first.
This is assuming that when they come back, they know they've been away and that their daughter's been fighting this huge mega war while they've been gone. If she can change their memories to forget they had a daughter at all, she can certainly change them so that they've forgotten that they forgot.
Also, there's not much evidence that they're aware of Voldemort and the like at all.
