I have a 2014 Model S (pre-autopilot) and a 2020 Model 3. The auto-dimming mirrors on the Model S work flawlessly. The auto-dimming mirrors on the Model 3 are unreliable.
There are lots of reasons why the feature may be unreliable -- could be it's a different technology than on the 2014 S, could be a bad sensor, a design flaw in the current system, a software glitch, etc.
By unreliable, let me explain what I mean for my particular case. Sometimes it will remain dimmed at night even when no cars are behind me. This will endure for a long time. Sometimes it doesn't dim at all when a car IS behind me. It's rather obnoxious, and makes me wish I had a manual control for it.
Does anyone know how the auto-dimming technology works on the 2020 Model 3? Is it using a light sensor? Is it analyzing the rear camera view? Something else? I'm wondering if I can improve it's performance somehow. For example, if it's analyzing the rear camera view, I could make sure to clean the camera before trips.
While I'm at it, I think I'll add a poll to help determine if I'm a unique case or if this is a common ailment, and for which cars/years. Don't know when technologies might have changed, but I'm splitting Model S responses to pre/post 2015 because that is roughly when autopilot was added, and I don't know...that was a big change and maybe the tech for the dimming changed too.
FYI: On the poll, by "work well", limit that to mean whether or not they dim and undim at appropriate times. I don't care if you think the dim it too strong or not, so don't factor that into your answer.
PS: I very much love the dimming side and rear mirrors. Probably one of my favorite features, given how often I drive on the highway at night. Just wish they worked better on my 3.
Thanks.
