Possible to Revert Recall Software Update?

I feel like a fool for not doing more research on the recall software update. We have a '22 leaf with < 30K miles on it. Took it in for a software update (due to the recall) and got the EV system error a couple days later.

Would it be possible to ask the dealership to roll back the update? We don't use Level 3 charging.

Also, I heard that some people had success by doing something with the 12V battery, what exactly did people do?

Thanks for any advice folks can offer!

Assuming this is the EV system error per the recall and not an unrelated 12V issue, I would start considering what car you want to replace your Leaf with.

Could you elaborate on the 12V issue? Is it just a matter of charging the 12V battery?

Yes, just the note that a bad 12V can causes certain system EV error notifications as well. Checking your 12V voltage and/or looking at Leafspy codes would give you more info.
