This. Current generation has failing ICCU's at staggering numbers. They replace them but haven't confirmed they fixed design issues. At least $2-3k.
Older ones (Kona) has reduction gear with some design flaw and Hyundai recommend changing its oil. Aaaaand it fails right at around 100k when most warranties lapse (cleverly their 8yr warranty is only for battery - likely most reliable component).
Bonus: just seen today Mercedes EQS has a motor seal design issue that at around 120kkm causes coolant intrusion. Tesla had same issue, but at least it was permanently fixable (aka coolant delete).
