Having owned a total of 4…
Having owned a total of 4 bolts, all of which were effected by the battery recall, I can confirm that your bad customer service experience is sadly typical. All four processes were a struggle for us.
Only one involved the software limitation, which allowed most batteries to avoid physical replacement. But the dealership was clueless about how it worked. When we requested the range limitation software update be replaced with the second software update to return the full range, they claimed "the original problem was that the batteries were incorrectly set to charge to 120%, so the reduced range to 80% actually makes it 100%, so there is nothing that needs to be done to return it to 100%.". Which is absolutely wrong. And it turns out they actually performed the update as it was an open recall, but didn't know that's what the software update did. I had to point out to them that the second software update would allow it to regain it's full charge after 6500 miles.
Almost as if taunting me, shortly thereafter, my kids who are the primary drivers, received calls from GM headquarters about completing the recalls, even though they had all been completed. Feels like complete chaos.
Either way, if the battery has been replaced, there should be no programming limited range, and there probably isn't, but the dealership will have no idea. One of the frustrating part of this is that, even with the reduced range, the car still indicates 100% charge, so it's difficult to easily know if the software is limiting rabbit.
Either way, I suggest calling GM directly, although they're aren't always very helpful, either.
