As is often the case, this subject is common to 3rd generation cars although not all will have this option.
Electrochromic mirror and GMPP
Has anyone else experienced this? My driver's side mirror went cloudy/patchy yellowed over the winter. I assume this is the gel layer gone bad. Car is a couple months out of factory warranty at around 60k km. Was told that GMPP Total Plus extended won't cover because glass is excluded. Well, yes...
