Not an EV, but I have a 2022 Kia Sorento with a fair number of weird software bugs-e.g. the sound from the navigation system randomly stops working and I have to restart the car to make it work again; the car tries to read speed limit signs using machine vision but its capabilities are too basic so it reads them incorrectly (in particular, conditional speed limits which only apply under a certain condition, such as at certain times of day, for heavy vehicles only, it will treat as absolutes)
Is their EV software better? Outside of cars, my experience with South Korean software hasn’t impressed me
