It may be good optics to issue the recall, but this is just the nature of most lithium chemistries as they age. Some of these packs are almost a decade old, well past warranty and well past the reasonable lifecycle of the cells in the first place. Most of these banks should have already hit recycling centers or landfills.

I don't keep lithium packs for more than a few years. Once they start showing signs of serious capacity loss and degradation they get replaced.
