I get it. I'm happy that a remote independent system can detect a major problem in advance of major consequences. And a pretty darn expensive problem on their part.
I was a little concerned that GM would have me drive the car for a week knowing the potential. And probably paranoia on my part, but on the way to the dealer this morning I did notice range jumping around, more than what I would expect with regen accounted for. Initially the dealer pushed me off, saying he was out of loaner cars. I pressed the issue and they got me a rental.
The service manager got to catch up on the issue by the time we checked in the Bolt. If I understood him correctly, he just learned that he would actually have to access the battery and find its serial number, to confirm it's a defective one, before ordering the new one.
The techs of course have never replaced a Bolt battery, but they have done Volts. I specifically asked the GM rep on the phone how long would the actual labor be, once the battery arrived? She said a few hours. I asked the service manager the same question and he laughed at the first answer. A few days he said. Some factors included when the appropriate techs were available, and would a bay be available.
The honeymoon over comment is because, to me, I no longer have the shiny new car. There's always a point where it's no longer new. For some, it's when the dog throws up in it, right? The climate control repairs on my previous Leaf rendered me a car that was never the same, and much less enjoyable. So I am skeptical about a repair that involves such a costly part. But I admit I don't know anything about the work. Maybe I should picture it like a new battery for my smoke detector, and all will be well!
