2025 Lucid Air — service lifetime transmission fluid or leave it alone? — anyone dealt with this recently?

I wouldn't throw parts yet. Capture voltage while the 2025 Lucid Air is actually failing — after it restarts you've lost the clue. You'll know quickly if you're on the wrong tree. If it doesn't change the out-the-door or the repair estimate, it's noise. I'll poke at it this weekend.

I'd want a measurement, not a hunch. Swap the cheap/easy piece first on the 2025 Lucid Air and see if the fault moves. If the cheap test changes it, stop and reassess. If it doesn't change the out-the-door or the repair estimate, it's noise. I'd sleep better after that step, even if it finds nothing. Wrote this up on my lunch break.

Intermittent stuff lies if you only catch it once. Write temp, speed, and in-gear vs coast when the 2025 Lucid Air does it — then decide on parts. You'll know quickly if you're on the wrong tree. On “service lifetime transmission fluid or leave it,” that was the fork that mattered for me. Just my two cents from doing this recently. Happens in gear, not in park, for what that's worth.
