Prius c Four, Sideview Mirror Broken

I've had my c Four for three weeks and I carefully fold in the sideview mirrors every night.

Unfortunately the driver’s side mirror is already broken. When folded in there’s about an inch of horizontal ‘play.’ Took it in to the dealer; technician somewhat roughly slammed it back and forth and said the spring was damaged and that the whole thing needed to be replaced. I hate the thought of the door of my brand new car being taken apart already…
