There are two defects, a torn anode tab and a folded separator. They implied both defects were occurring simultaneously in a cell but didn't indicate if all cells are affected. They did however identify that the issues came from multiple factories in the US and Korea, which indicates the problem might be with every single cell manufactured.
GM said they don't trust the stock of packs they have in warehouses or any installed in EVs. They are requiring LG to implement GM's level of QC, which we must presume is higher than LG's existing QC.
No batteries will be fixed in any EV until GM is confident that LG can actually manufacture the cells without defect. At that point in sounds like all packs will we fully swapped in all EVs made.
