2023 Rivian R1T — humming rises with road speed, not engine RPM

TowMechanicish588Community StarterJan 13, 20262023 Rivian R1T Quad-MotorOrange County

2023 Rivian R1T Quad-Motor, about 42,500 miles. There is a low hum that rises with road speed regardless of engine RPM. Turning slightly left or right changes the sound. Is that enough to suspect a wheel bearing, or what else should I rule out?

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. I'd do that before spending real money. This is from a 2023 Rivian R1T in Orange County with 42,500 miles. When does it actually happen? I already checked the easy fluid levels.

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 “humming rises with road speed, not engine,” that was the fork that mattered for me. Run the total, not the monthly, before you commit. Checking again after work.

I went back under the 2023 Rivian R1T and it only happens after a heat soak, not on a cold start. I refuse to clear codes until someone else sees them.

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. Take it or leave it — that's what I'd do. I'll update if anything new shows up.
