2024 Kia EV9 — going one inch smaller for winter wheels — trying to narrow this down

Ask what changed right before it started. If a shop can't duplicate it on the 2024 Kia EV9, bring a video plus freeze-frame data, not just a story. That's the branch I'd chase this week. I'd want a dollar figure or a measured spec, not 'should be fine.' If the story changes I'll post the new data.

Intermittent stuff lies if you only catch it once. Get a real battery/charging test on the 2024 Kia EV9, not just resting voltage, before blaming a module. That's the branch I'd chase this week. On “going one inch smaller for winter wheels,” that was the fork that mattered for me. This is from a 2024 Kia EV9 in San Diego with 25,500 miles. That's the whole play. This is the filter I use when the thread starts repeating itself. Heat soak after errands is the other window.

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 2024 Kia EV9 does it — then decide on parts. That's the branch I'd chase this week. That's the whole play. Your commute and mine probably aren't the same, but the test still applies. If the story changes I'll post the new data.
