I’ve only seen an EV do that once. The 12V battery died about a week later. (Or, rather, I left it parked, and after pouring 10% (!!) of the high voltage battery into the 12V, it gave up and completely shut down.)

Anyway, I wonder if Tesla’s are missing the “if 12V is completely shot, give up” logic. Replacing it is cheap and might fix the car. Some models let you monitor the 12V charger with an OBD-II dongle.

That’d let you prove me right or wrong.

Just to be clear, I actually had Tesla replace the 12V last year because I was worried that was the cause.

The problem did not improve.
