Do you think the C has weak alignment retention?

i had a Yaris before and I'm starting to have the same feeling about the Prius c as I did with the Yaris, that alignment retention is not very strong. It's almost like if you look at the C the wrong way, your alignment will go out of whack.

Got an alignment only a week ago on a month old C because it was out of spec..less than a week later, it once again feels like it's having too much toe-in.

Michigan roads are awful, but I havnt hit anything drastic that I feel would throw the alignment out again. How's your alignments been holding up?
