The dealer diagnosed a failure of the ICCU and replaced it. The vehicle was in the shop for approximately 2 weeks. More recently, on…

It was brought to my local Hyundai dealer and a few days later they confirmed it was the ICCU problem. This is a safety issue. Fortunately I was 1 mile from my house and did not get stranded. Hyundai has had four years to fix the problem and obviously they…
