Yesterday, my mirror accidentally hit a construction barrel that was sticking out further than the others. When it hit, my mirror flipped in and I didn't think much of it. When I got to work, I noticed the back of the mirror was gone. It looks like a piece you can get and just snap on. I have a 2018 Prime. Is this something I can order myself? I doubt my dealership has the part laying around. Or should go to the Toyota body shop?
I knocked mine off leaving the garage one day. (Lame, I know.) I didn't notice the back was off until a couple of days later. Then I found the parts in the garage; the shell had fallen behind a mop and the faux chrome trim piece had fallen into the bucket where I keep the driveway deicer. It all snapped back together with no problem. I was worried that the latch points on either the mirror, trim or cover might have broken, but that doesn't seem to have happened. Hopefully, you will be similarly fortunate.
