Consumer Description

The Ioniq 5 has a known issue with a part called the ICCU. When the part fails, which it seems to inevitably do despite multiple recall repair visits and software upgrades, the car ceases to be driveable. In advance of this moment when your multi ton vehicle turns into a brick you get a short warning saying pull over, but that is not always possible. The car starts loudly beeping and reduces its max speed to 12 mph, which is not great on the freeway. The ICCU is a huge safety problem, a known issue that Hyundai is well aware of, and the part needs to be redesigned and the NTSB needs to force Hyundai to extend greater warranty protections for this event. This just happened to me, the dealership says they have 8 other ioniq 5's in with the same issue and I am number 9 on an ioniq 5 iccu loaner car waiting list while the part is back ordered for at least one month. My car stopped at a stop light and fully blocked an intersection when it bricked as I came off the freeway, was super scary to sort out in the middle of the road and I was very happy that my twin toddlers were not in the back seat, i was not so happy I had to pay to have the vehicle towed and arrange a comedicly complicated way to pickup my kids due to this known issue parts failure.
