Question: Model Y low-voltage warning before a road trip

OldSchoolCollectorCommunity StarterJul 8, 20262024 Tesla Model Y Long RangeTexas
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? Appreciate any ideas on what to check first.

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. I'd do that before spending real money. Run the total, not the monthly, before you commit. Might be overthinking it, but I'd rather overthink than overspend.

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. If it doesn't change the out-the-door or the repair estimate, it's noise. Make the next action something you can finish this week. This is the version I'd tell a friend.

Yes, with one caveat: Leave the alerts on the 2024 Tesla Model Y so service can see what you saw. Then you'll know the next fork. Parts cannon is a personality type I try to avoid. If it repeats twice more I'll book time.
