2024 Rivian R1S — how much does an old accident hurt resale?

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2024 Rivian R1S so service can see what you saw. That's where I'd start. When does it actually happen? I'd sleep better after that step, even if it finds nothing. Parking it somewhere I can hear it better next time.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2024 Rivian R1S charge sessions. Then you'll know the next fork. Post the numbers (or the code) and people can get more specific. I'd rather look cautious in this thread than stuck later.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2024 Rivian R1S — site sharing and pack temp change the curve a lot. That's where I'd start. Have you gotten a second quote in writing? If that fails I'll eat the diagnostic fee.
