Had to have the head unit replaced on my Limited. All kinds of false driver alerts, take a break, hands on steering wheel, voice nav stopped working, tilt down side view mirrors not working when in reverse. The new head unit no longer includes the Quantum sound option that I paid for. What's up with that? The dealer had no idea what I was talking about when I said it was missing. They said the system was revised to speed up processing. They did try to reinstall that option but no luck. Also, they send in the VIN and get what they get from Hyundai. The new unit seems to be failing now as well. It's a cumulative process so gets worse as you go. The best fault is opening the sunroof which activates nav voice and wants to know where I want to go! It's all intermittent so when the shop gets it they find no issue. It's too bad, otherwise, nice car.
