Consumer Description

My car failed to charge on my level 2 home charger and would only charge on a level 3 fast charger. Because of this, I was unable to charge my car at home. I was on a trip about 1 hour from my home in an area of Massachusetts that developed an electrical blackout. I almost ran out of power on a dark road with no streetlights. I was lucky to find a level 3 charger just on the outside of the blackout area when my car had less than 5% power. I brought the car to the Hyundai service center 2 weeks ago. I called daily for updates and was told they were "diagnosing" the problem. I called again, yesterday and was told it needed an ICCU. It had been ordered that afternoon (2/5/26) and they hoped it would arrived within the week. They were unable to provide a loaner car (even though I've been without a car for two weeks).
