Anyone else: Model Y low-voltage warning before a road trip

2024 Tesla Model Y Long Range, about 96,000 miles. 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. Ambient temp was about 58°F when I noticed it.

I'd treat 12V warnings as a no-ignore. On the 2024 Tesla Model Y, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. I'd do that before spending real money. On “model y low-voltage warning before a road,” that was the fork that mattered for me. This is from a 2024 Tesla Model Y in North Jersey with 96,000 miles. Happy to compare notes if your setup is different. If your situation is the opposite, ignore me. I'm keeping receipts and dates in one folder.
