This is one of my pet peeves. If your 12v system starts dropping voltage you get all kinds of system error messages. Dollar signs start flashing in your mind as your told to bring the vehicle in for service.
I think the first message should always be “12v system is low..... ignore all of the next messages”.
Wish EV manufacturers would show us the 12v system voltage like cars used to do. I’m thinking of buying one of those cigarette lighter 12v meters just to keep an eye on it.
