2024 Buick Envision — check-engine light turned itself off — still scan it?

Start with the test that can prove you wrong. If a shop can't duplicate it on the 2024 Buick Envision, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. If you share a photo of the worksheet, easier to sanity-check. I've seen both outcomes, which is why I'd test instead of assume. Happens in gear, not in park, for what that's worth.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2024 Buick Envision is losing coolant with no puddle. If the cheap test changes it, stop and reassess. This is from a 2024 Buick Envision in San Antonio with 17,500 miles. If you share a photo of the worksheet, easier to sanity-check. I'd rather be boring and correct. Heat soak after errands is the other window.

Ask what changed right before it started. A pressure test beats staring at a dry driveway if the 2024 Buick Envision is losing coolant with no puddle. If the cheap test changes it, stop and reassess. Do that first. That's coming from doing this as an owner, not a shop. I refuse to clear codes until someone else sees them.
