Anyone else: How are you estimating real battery degradation?

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. This is from a 2024 Rivian R1S in Michigan. Happy to compare notes if your setup is different. Worth doing even if the car feels fine right now. Might be overthinking it, but I'd rather overthink than overspend.

I'd treat 12V warnings as a no-ignore. On the 2024 Rivian R1S, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. I'd do that before spending real money. On “how are you estimating real battery degradation,” that was the fork that mattered for me. That's the whole play. I refuse to clear codes until someone else sees them.

Checked the easy stuff on the 2024 Rivian R1S and found one clue worth chasing before I book a shop. Doing the boring step first on purpose.

On “how are you estimating real battery degradation,” that was the fork that mattered for me. This is from a 2024 Rivian R1S in Michigan. Time, temperature, and whether it's in gear are the notes that actually help a shop. I'll update if anything new shows up.

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. Then you'll know the next fork. Do that first. I'm keeping receipts and dates in one folder.

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. Then you'll know the next fork. When does it actually happen? I'll update if anything new shows up.

I'd do that before spending real money. Stop there until you know. Worth doing even if the car feels fine right now. I'm in no rush to be a hero on it.

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. That's where I'd start. If you share a photo of the worksheet, easier to sanity-check. I'll update if anything new shows up.

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. I'd do that before spending real money. Write the result down so the next test isn't a repeat of the last one. Only after sitting overnight so far.

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. That's coming from doing this as an owner, not a shop. Cold start is when I can actually reproduce it.

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. Any freeze-frame data saved? I'd rather be boring and correct. Might be overthinking it, but I'd rather overthink than overspend.

Next check is the cheap one I can do in a driveway.

I'd do that before spending real money. This is from a 2024 Rivian R1S in Michigan. If you share a photo of the worksheet, easier to sanity-check. I've seen both outcomes, which is why I'd test instead of assume. If it repeats twice more I'll book time.
