2024 Tesla Model Y Long Range — need advice: Low-voltage battery warning after software update

2024 Tesla Model Y Long Range, about 118,000 miles. A software update finished overnight and this morning I got a low-voltage battery warning. Main battery is charged. Before scheduling service, is there anything safe to check in the app/service menu?

Tried a second charger / second scan and the story on the 2024 Tesla Model Y didn't change. Happens in gear, not in park, for what that's worth.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2024 Tesla Model Y so service can see what you saw. That's where I'd start. Not gospel, but it saved me a headache. I'd rather be boring and correct. Only after sitting overnight so far.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2024 Tesla Model Y charge sessions. I'd do that before spending real money. Do that first. Checking again after work.
