2021 Hyundai Palisade — rough idle disappears just above idle speed

Ask what changed right before it started. Capture voltage while the 2021 Hyundai Palisade is actually failing — after it restarts you've lost the clue. If the cheap test changes it, stop and reassess. Verbal 'we'll take care of it' is not a plan. I'll poke at it this weekend.

Intermittent stuff lies if you only catch it once. If a shop can't duplicate it on the 2021 Hyundai Palisade, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. On “rough idle disappears just above idle speed,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. Next check is the cheap one I can do in a driveway.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2021 Hyundai Palisade and see if the fault moves. Don't erase codes until someone who can help has seen them. This is from a 2021 Hyundai Palisade in Northern Virginia with 50,000 miles. Happy to compare notes if your setup is different. I'll poke at it this weekend.

This is usually cheaper to test than to guess. Swap the cheap/easy piece first on the 2021 Hyundai Palisade and see if the fault moves. That's the branch I'd chase this week. This is from a 2021 Hyundai Palisade in Northern Virginia with 50,000 miles. Time, temperature, and whether it's in gear are the notes that actually help a shop. Trying not to diagnose from the couch.

I'd want a measurement, not a hunch. Two 2021 Hyundai Palisades can feel identical and have different causes, so measure before you copy someone else's repair. You'll know quickly if you're on the wrong tree. If it doesn't change the out-the-door or the repair estimate, it's noise. I'd sleep better after that step, even if it finds nothing. Trying not to diagnose from the couch.

Log the conditions before you spend. If a shop can't duplicate it on the 2021 Hyundai Palisade, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. On “rough idle disappears just above idle speed,” that was the fork that mattered for me. A shop burned me once by skipping that step. Only after sitting overnight so far.

Start with the test that can prove you wrong. A pressure test beats staring at a dry driveway if the 2021 Hyundai Palisade is losing coolant with no puddle. Save the big job until that test fails. Verbal 'we'll take care of it' is not a plan. I've seen both outcomes, which is why I'd test instead of assume. I refuse to clear codes until someone else sees them.

This is me being the wet blanket on purpose.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2021 Hyundai Palisade is losing coolant with no puddle. Don't erase codes until someone who can help has seen them. That's the whole play. No warning lights, which is why I'm documenting it.
