I have had so many issues with my 5, flat 12v, drastic battery loss (main traction battery) but we loved the car so much we are going with another one, I have done the research and it seems its all related to the iccu, basically they know their is a issue as all their have been 5 in total iccu software updates, with the last one being a govt involved thing due to safety concerns.. apparently all the december 2024 onward cars have the newer version of the iccu which has a different part number.
