I have had my 2017 Volt for close to year now, and the one thing I hate, is the self dimming mirror. Good thing I drive +90% of the time in the daytime, because the mirror doesn't dim at all. It simply puts a greenish hue into the blinding glare of the headlights from the car behind. My solution is to angle the mirror up enough, that I can see into it, if I stretch my neck up. I miss the manual lever on my 2009 Cobalt.
