Model Y low-voltage warning before a road trip

Low-voltage battery warning appeared and I have a trip coming up. Main pack is fine. I don't want to get stranded over the small battery—what would you consider a no-drive warning versus something safe to take straight to service? I'd rather test this logically than start replacing parts.

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. This is from a 2024 Tesla Model Y in NYC / Long Island. Have you gotten a second quote in writing? No warning lights, which is why I'm documenting it.

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. Then you'll know the next fork. If you share a photo of the worksheet, easier to sanity-check. Cold start is when I can actually reproduce it.
