2024 Rivian R1S Dual-Motor — question: First used oil analysis — what should I care about?

2024 Rivian R1S Dual-Motor, about 37,000 miles. Thinking about sending an oil sample in mostly to establish a baseline. For a normal street car, which numbers are actually useful over time and which ones do people overreact to?

Checked the easy stuff on the 2024 Rivian R1S and found one clue worth chasing before I book a shop. If this is nothing, great. I want that in data.

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. This is from a 2024 Rivian R1S in Los Angeles with 37,000 miles. Have you gotten a second quote in writing? I already checked the easy fluid levels.

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. I'd do that before spending real money. If you share a photo of the worksheet, easier to sanity-check. Might be overthinking it, but I'd rather overthink than overspend.

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. Verbal 'we'll take care of it' is not a plan. I'll update if anything new shows up.
