There was an issue early with the mirrors. Both motors in mine were replaced and I think there was a software update to fix the issue. The motors originally would fold and not turn off, causing the motors to fail. .
As a "homemade" fix you may want to turn off Auto Fold and open the mirror manually. I have turned mine off although they still function. My thought is there are only so many "cycles" on the small motors so I fold them only when I think warranted.
I'll leave the experts here for software update and motor replacement.
