2025 Lucid Air — eV has plenty of main battery but shows a 12V warning — second opinion before I spend money

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2025 Lucid Air charge sessions. I'd do that before spending real money. No need to make it theatrical. Cold start is when I can actually reproduce it.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2025 Lucid Air — site sharing and pack temp change the curve a lot. Then you'll know the next fork. If they can't show the line item, I assume it's hiding. That's my plan before I call anyone.

I'd treat 12V warnings as a no-ignore. On the 2025 Lucid Air, 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 “ev has plenty of main battery but,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' This is the version I'd tell a friend.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2025 Lucid Air so service can see what you saw. That's where I'd start. Do that first. Heat soak after errands is the other window.

OP here — recorded a short video and noted speed, temp, and whether it was in gear. Parking it somewhere I can hear it better next time.

Cleared nothing. I want service to see the alert on the 2025 Lucid Air first. Happens in gear, not in park, for what that's worth.

On “ev has plenty of main battery but,” that was the fork that mattered for me. That's the sequence I'd use. Might be overthinking it, but I'd rather overthink than overspend.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2025 Lucid Air — site sharing and pack temp change the curve a lot. Then you'll know the next fork. This is from a 2025 Lucid Air in San Diego with 20,000 miles. Run the total, not the monthly, before you commit. I've seen both outcomes, which is why I'd test instead of assume. No warning lights, which is why I'm documenting it.

OP update: scanned the 2025 Lucid Air again and still only have the one pending code, no new lights. I already checked the easy fluid levels.

If it doesn't change the out-the-door or the repair estimate, it's noise. I refuse to clear codes until someone else sees them.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2025 Lucid Air so service can see what you saw. That's where I'd start. I'd want that in writing, not as a promise. I'd sleep better after that step, even if it finds nothing. I already checked the easy fluid levels.

Verbal 'we'll take care of it' is not a plan. I've seen both outcomes, which is why I'd test instead of assume. I'm keeping receipts and dates in one folder.

Update: the cheap test changed the symptom, so I'm not throwing parts yet. Next check is the cheap one I can do in a driveway.
