2021 Hyundai Palisade — check-engine light turned itself off — still scan it?

GarageDetailer721Community StarterApr 30, 20262021 Hyundai Palisade LimitedDenver
2021 Hyundai Palisade Limited, about 58,500 miles. The light was on for two days and then disappeared before I could schedule service. Car feels normal. Is there still likely to be useful stored or pending data if I scan it now? I am in Denver.

If it were in my driveway, if a shop can't duplicate it on the 2021 Hyundai Palisade, bring a video plus freeze-frame data, not just a story. You'll know quickly if you're on the wrong tree. If you share a photo of the worksheet, easier to sanity-check. I already checked the easy fluid levels.

Not convinced that's the whole story. A pressure test beats staring at a dry driveway if the 2021 Hyundai Palisade is losing coolant with no puddle. That's the branch I'd chase this week. That's the whole play. I'd rather pay for diagnosis than a second guess-repair.
