“ICCU failure. Warning lights came on in the dash and diagnostic codes were available in my Hyundai app. My family and I had just gotten back from a road trip and if the ICCU would have failed while we were on the trip we would have been stranded and it would have been during the heat wave. The vehicle is currently in the service department waiting for the part to come in.”
