I'm wondering if they are still building 24kwh packs as needed, or using older new packs.
My understanding is that they build a pack from an old (recycled) shell and new cells. I don't know whether you get a new BMS/contactor box/harness/etc; I suspect not. You have to surrender your old shell, for the process to continue.
Edit: at least in one case in Australia, now several years ago, they the replacement cells were new but old (probably canary) chemistry. The replacement pack degraded at a similar rate to the original 2012 pack. I would hope that they don't manufacture the horrible chemistry cells any more, so you get better cells than original, but I don't know.
Edit 4: http://ozleaf.proboards.com/post/15648/thread
. Per email, the owner has not lost his second capacity bar yet, with 9,000 more km (5,600 mi, 15% more) on the clock compared to when the first battery dropped its second capacity bar, so maybe it's the Wolf chemistry.
Edit 3: that was for a warranty replacement pack, but I assume it's the same for non-warranty.
