Consumer Description

One month ago, my car experienced an failure and the warnings on the dash reported to check the electrical supply and then to stop driving the car immediately. I had it towed to a dealership who reported the ICCU failed and it'd take 1-2 weeks to get replacement parts and repair. A month later, I was just told the part is on indefinite back-order and they have no ETA when a replacement part will be available. Hyundai is selling an unsafe vehicle without that can die on the road and have no way to fix the issue. Google "Hyundai ICCU failure" and you'll see this is a systemic problem and Hyundai is doing nothing to fix these issues and is putting out 2025 models that are dying on the road with no solution.
