First post.

Although I have had the car since November I have not done many miles due to an eye problem. However, I am beginning to use it on a more regulare basis but most of my journeys are short.

In the last few days I have had 12v battery warning lights appear in the Digital Instrument panel. I tried driving for a couple of hours but the warning lights remained. I did an overnight charge to 80% but in the morning the warning lights were still on.

I will try an overnight charge to 100% and see if this fully charges the 12v battery. Does the high-voltage charge only charge the 12v battery when it reaches 100%?

The 12V battery is charged from the 400V battery when the car is driving (well, in 'Ready' mode at least). It will not charge when the car is switched off.

In theory it shouldn't ever really get that low, but there were some reports of ID.3s suffering from discharging 12V batteries when only used for short journeys - and I think there's some work around the 12V system in the upcoming update. Alternatively - either try a longer drive (maybe an hour out and an hour back), or simply attach a battery charger to the 12V battery and charge it for a couple of hours from the mains.
