At the risk of sounding like a broken record I think I've now worked out the circumstances of when the dome lights setting on my car change from AUTO to OFF and I wondered if anyone else could see if the same thing happens to them so I can raise it as a bug.
So...
Thank you
- Set the dome lights (interior lights) to auto
- to test thoroughly I guess you could get in and out of the car several times to make sure the setting remains on auto
- Open the entertainment screen and then either Netflix or YouTube
- if your interior lights were on when you did this, you may find them go off as soon as either is opened
- Close the entertainment view and check dome light settings
- without fail, mine always get reset to off
I ended up emailing the bug to one of the Tesla email addresses and they passed it on to the relevant department. I got a call a couple of hours later from an engineer who confirmed that this is a known firmware bug. He forced update 2020.8.2 to me on the off-chance that might fix it, but it hasn't.
At least I know it's a known issue, will just have to wait for a fix and, in the meantime, manually switch my dome (interior lights) back to auto after watching Netflix or YouTube .
