That confirms it's a hardware fault and we should just let Tesla fix it. I would prefer a 1 day inconvenience to a permanent inconvenience and permanent devaluation of the car over what is a hardware warranty repair issue.
Since the software work around is their way of not fixing it, we are better off not updating. Either we are never permanently inconvenienced by the voltage limitations, or we are briefly inconvenienced by a failure that brings us back to full voltage. The worst possible outcome from all of these options is to update and be forever harmed by Tesla's refusal to repair warranty covered parts.
As long as it isn't a safety issue, the smart choice is to skip the update and keep the car functional as originally delivered.
