It is just possible that it relates to bugs in how well the BMS can detect and manage the SoC while charging as the battery ages, which will change its characteristics.Latest update on mine from today's visit. They said they've applied some more patches to it and it has improved somewhat but they're not happy leaving it like that, so they have kept the car in and raised a case with MG. I should get an update on next steps tomorrow. In their words they are convinced it's a software issue; well maybe so but I don't understand how a software issue suddenly manifests when no software patches have been applied to the car since it was delivered, unless MG are delivering some updates over the air.
But I agree it seems unlikely.
Even less likely that the software get into an inconsistent state after 6-9 months running - but I suppose possible, my charging lights stopped working a while ago.
