The implication that it NEEDED a new battery is problematic because it paints a bad picture to neophytes. It probably didn't. However, if they CHOSE to install a new battery in the interest of expedience, that's great.
Not getting what you would do differently. The dealer ran diagnostics and the battery pack is being replaced. The battery is a FRU, not field serviceable. It's also unlikely that there are many available software engineers at the dealer service department to recode software/firmware bits on the fly. If they replace the battery and the car is back on the road, then that was the right thing to do. If it doesn't, then it's not.
I'm not saying I'd do anything differently. Having done dozens of local EV car shows and interacting with the general public, I can tell you that "the battery" is their biggest fear and the single item they worry about most. While what they did is the correct and expedient thing to do, the truth is that with it likely COULD have been repaired with only minor parts swapped. But because the cars aren't common, their failure modes aren't well known, and dealers aren't yet well versed in them, it is a common strategy to "replace and analyze". If someone told you their car had "the engine" replaced, you'd think it was a major failure when maybe all that was needed was a new fuel injector. No big deal, parts fail. Replacing "the battery" sounds just as bad as replacing "the engine" when maybe all it really need was a new capacitor or a loose contractor. I'm just saying that making the quick replacement makes things sound worse than it probably was. And that's not what an already leery public needs to hear. Of course, neither is being out of commission for a month while they tear the battery down and try to figure it out.
