The dealership I go to says they are seeing them in fair amount. It's definitely an issue.Other than Unobtanium, I have not seen anyone else post about failed mirrors. It's really interesting and I have to wonder what the reason is his particular car has so many issues with the mirrors. My '19 is at 14k and haven't had a single issue so far. Mine is leased so not really concerned. They will be covered for the entire 3yrs I have the car by the factory 3/36 warranty..
