12V Problem after Recent Update

[Wilson]

Within 24 hours of the most recent update, I got a 12V error message in the app. I contacted service. Followed directions and it went away the next day. 5 days later the error come back but only after the 12V was dead and my R1S couldn’t be opened or charged. The main battery was at 61% when the 12V died so it wasn’t a main battery or draining issue (not a proximity issue either). No seatbelts plugged in or anything else. The technician replaced it but was perplexed.

did anyone else have this issue or have any ideas how it might have happened?

Check if there were any firmware or software updates closely linked to the 12V system in the recent patch. It could be a nuanced compatibility issue that needs attention.

When these vehicles install new updates, they do a hard reset right after to apply the changes. It's well known at this point that hard resets put a significant amount of stress on the 12V battery system. It's possible your 12V battery was already going back and the update simply exacerbated that issue.

For others finding this thread because they also hit a 12V system error that went away, I highly recommend pressuring your service center to replace the 12V battery right away to avoid getting stuck without being able to access or drive your vehicle.

Agree, and the technician reiterated that as well. It was disconcerting because the warning went away right after contacting Rivian service, and I attributed it to a bug which was a mistake in hindsight.

I don't blame you in this scenario at all. I think there's still quite a bit of unknown to be addressed in how Rivians maintain their 12V batteries and what's causing a lot of these issues.
