2023 Rivian R1T — rear tires are disappearing faster than expected — trying to narrow this down

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2023 Rivian R1T charge sessions. That's where I'd start. I'd want that in writing, not as a promise. I refuse to clear codes until someone else sees them.

I'd treat 12V warnings as a no-ignore. On the 2023 Rivian R1T, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. Then you'll know the next fork. On “rear tires are disappearing faster than expected,” that was the fork that mattered for me. Run the total, not the monthly, before you commit. Climate here is different, so treat that as a local data point. Video is ugly but it shows the hesitation.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2023 Rivian R1T — site sharing and pack temp change the curve a lot. I'd do that before spending real money. This is from a 2023 Rivian R1T in Northern Virginia with 48,000 miles. Do that first. I've seen both outcomes, which is why I'd test instead of assume. If this is nothing, great. I want that in data.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2023 Rivian R1T charge sessions. That's where I'd start. Run the total, not the monthly, before you commit. That's coming from doing this as an owner, not a shop. Parking it somewhere I can hear it better next time.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2023 Rivian R1T so service can see what you saw. Then you'll know the next fork. I'd want a dollar figure or a measured spec, not 'should be fine.' Wrote this up on my lunch break.
