As an owner of a used EV6, I can tell you this issue has caused some concern and I do think it's a real but rare issue. However, my calculation is this: It's a 1% impacted issue. Replacing with an AGM battery drastically reduces the issues. Recalls somewhat mitigate this issue further. Apparently reducing your L2 charging rate to < 7kW also reduces this. At the end if you are still unlucky, the ICCU is almost always covered by warranty but replacement is annoying and can take months. To mitigate I plan to replace my stock 12V with AGM, and buy a portable battery starter.
