2021 Tesla Model S — eV has plenty of main battery but shows a 12V warning — North Jersey owner question

I'd treat 12V warnings as a no-ignore. On the 2021 Tesla Model S, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. Then you'll know the next fork. On “ev has plenty of main battery but,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. This is the filter I use when the thread starts repeating itself. Only after sitting overnight so far.

I already checked the easy fluid levels.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2021 Tesla Model S — site sharing and pack temp change the curve a lot. I'd do that before spending real money. Take it or leave it — that's what I'd do. Only after sitting overnight so far.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2021 Tesla Model S so service can see what you saw. Then you'll know the next fork. Keep sale price, fees, and rate as three different conversations. I'll poke at it this weekend.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2021 Tesla Model S charge sessions. Then you'll know the next fork. Any freeze-frame data saved? Video is ugly but it shows the hesitation.

Verbal 'we'll take care of it' is not a plan. That's coming from doing this as an owner, not a shop. Trying not to diagnose from the couch.
