2020 Acura RDX — check-engine light turned itself off — still scan it?

Log the conditions before you spend. Capture voltage while the 2020 Acura RDX is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. On “check-engine light turned itself off — still,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. Climate here is different, so treat that as a local data point. I refuse to clear codes until someone else sees them.

OP update: scanned the 2020 Acura RDX again and still only have the one pending code, no new lights. This is me being the wet blanket on purpose.

If it were in my driveway, two 2020 Acura RDXs can feel identical and have different causes, so measure before you copy someone else's repair. If the cheap test changes it, stop and reassess. This is from a 2020 Acura RDX in Austin. I'd want a dollar figure or a measured spec, not 'should be fine.' This is me being the wet blanket on purpose.

Ask what changed right before it started. Swap the cheap/easy piece first on the 2020 Acura RDX and see if the fault moves. Don't erase codes until someone who can help has seen them. Time, temperature, and whether it's in gear are the notes that actually help a shop. Might be overthinking it, but I'd rather overthink than overspend.

Intermittent stuff lies if you only catch it once. Capture voltage while the 2020 Acura RDX is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. On “check-engine light turned itself off — still,” that was the fork that mattered for me. This is from a 2020 Acura RDX in Austin. Had a similar mess a couple years ago and that's what finally sorted it. This is the filter I use when the thread starts repeating itself. I refuse to clear codes until someone else sees them.

This is usually cheaper to test than to guess. If a shop can't duplicate it on the 2020 Acura RDX, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. A shop burned me once by skipping that step. Cold start is when I can actually reproduce it.

Intermittent stuff lies if you only catch it once. If a shop can't duplicate it on the 2020 Acura RDX, bring a video plus freeze-frame data, not just a story. That's the branch I'd chase this week. On “check-engine light turned itself off — still,” that was the fork that mattered for me. If they can't show the line item, I assume it's hiding. I'll update if anything new shows up.
