2023 Jeep Wrangler — check-engine light turned itself off — still scan it? — second opinion before I spend money

Intermittent stuff lies if you only catch it once. If a shop can't duplicate it on the 2023 Jeep Wrangler, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. On “check-engine light turned itself off — still,” that was the fork that mattered for me. That's the whole play. This is the filter I use when the thread starts repeating itself. I'm keeping receipts and dates in one folder.

I wouldn't throw parts yet. Get a real battery/charging test on the 2023 Jeep Wrangler, not just resting voltage, before blaming a module. Save the big job until that test fails. This is from a 2023 Jeep Wrangler in New Jersey. Stop there until you know. That's my plan before I call anyone.

I'd want a measurement, not a hunch. If a shop can't duplicate it on the 2023 Jeep Wrangler, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. I'd want that in writing, not as a promise. Cold start is when I can actually reproduce it.
