Need advice: Rivian 12V warning: drive to service or request mobile help?

Got a 12V-related service warning and the truck otherwise wakes and drives normally. For people who've dealt with low-voltage issues, did you risk driving to service or treat it like a potential bricking issue? I'm in Salt Lake City. Trying to diagnose before I book a shop.

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. Then you'll know the next fork. I'd want a dollar figure or a measured spec, not 'should be fine.' I'm in no rush to be a hero on it.

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. That's where I'd start. On “rivian 12v warning: drive to service or,” that was the fork that mattered for me. This is from a 2023 Rivian R1T in Salt Lake City. Parts cannon is a personality type I try to avoid. This is the filter I use when the thread starts repeating itself. I'll update if anything new shows up.
