I can confirm it’s not software for me and that it’s pretty much confirmed a faulty USB port, so it might be the same for you. I’ve had this issue since picking up my car at the beginning of March (disconnected 3 times on my drive home from the dealership) and the dealership never updated my car to the November 2021 update. So I’ve had this issue even before the November 2021 update. Done all possible troubleshooting and now waiting on the replacement USB port part to arrive at my dealership. You might want our dealership to look into the same!had exactly the same thing happen. Seems random but definitely a software issue as tried multiple Apple certified cables. Hyundai told me to try with their branded cable- don’t seem to have one though. Can’t be cable though as worked perfectly prior to the recent (February) update. Does anyone have an earlier firmware available and know if it’s possible to downgrade?
