2023 Rivian R1T — dealer cannot reproduce an intermittent warning

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2023 Rivian R1T is losing coolant with no puddle. Don't erase codes until someone who can help has seen them. This is from a 2023 Rivian R1T in Austin with 29,500 miles. That's the sequence I'd use. I refuse to clear codes until someone else sees them.

Intermittent stuff lies if you only catch it once. Two 2023 Rivian R1Ts 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. On “dealer cannot reproduce an intermittent warning,” that was the fork that mattered for me. Any freeze-frame data saved? If that fails I'll eat the diagnostic fee.

Intermittent stuff lies if you only catch it once. Capture voltage while the 2023 Rivian R1T is actually failing — after it restarts you've lost the clue. You'll know quickly if you're on the wrong tree. On “dealer cannot reproduce an intermittent warning,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. That's my plan before I call anyone.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2023 Rivian R1T and see if the fault moves. Don't erase codes until someone who can help has seen them. Any freeze-frame data saved? Your commute and mine probably aren't the same, but the test still applies. Parking it somewhere I can hear it better next time.

I'd want a measurement, not a hunch. If a shop can't duplicate it on the 2023 Rivian R1T, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. That's the sequence I'd use. If that fails I'll eat the diagnostic fee.

I went back under the 2023 Rivian R1T and it only happens after a heat soak, not on a cold start. Might be overthinking it, but I'd rather overthink than overspend.
