Low-voltage battery warning after software update

BatteryDadCommunity StarterNov 8, 20252024 Polestar 2 Long Range Dual MotorCentral Florida
2024 Polestar 2 Long Range Dual Motor, about 22,000 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? Any data points from owners would help.

I'd treat 12V warnings as a no-ignore. On the 2024 Polestar 2, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. That's where I'd start. On “voltage battery warning after software update,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' Doing the boring step first on purpose.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2024 Polestar 2 — site sharing and pack temp change the curve a lot. Then you'll know the next fork. This is from a 2024 Polestar 2 in Central Florida with 22,000 miles. The universe charges extra for guessing. I keep a notes app thread for this now.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2024 Polestar 2 so service can see what you saw. I'd do that before spending real money. I'd want that in writing, not as a promise. I'd sleep better after that step, even if it finds nothing. I'd rather look cautious in this thread than stuck later.
