Owner report 11669628 · 2025-06-27 (June 27, 2025)
My ICCU failed, which caused a fuse to blow and some electrical wiring in the car to melt. This caused the car to completely deplete the 12V battery, which left the car completely inoperable. The vehicle was towed to a Hyundai dealership, where they ordered the relevant parts and changed them under warranty. I was without the car for roughly two weeks.

Owner report 11689514 · 2025-09-24 (September 24, 2025)
Occasionally while driving my IONIQ 9 in sunny conditions with glasses on while utilizing Lane Keep Assist and the Adaptive Cruise Control system the car flashes a Warning about keeping your attention on the road, and then continues on beeping and chiming before ultimately completely stopping in the middle of the road unless you disengage the Lane Keeping Assist and Adaptive Cruise Control. I believe the sensors on top of the Steering Wheel aren’t calibrated that great for people who wear glasses, as this issue does not occur when I take my gla…

Owner report 11711434 · 2026-01-16 (January 16, 2026)
The Integrated Charge Controller Unit (ICCU) failed at 7622 miles, causing the pyrotechnic fuse to fail as well. The vehicle was towed to the nearest Hyundai dealer. Repairs took 2 and 1/2 weeks due to parts availability. My wife, who was driving at the time, could have been stranded. Fortunately, the failure occurred close to our home. The dealer did confirm the fault code and failure of the ICCU and fuse. Warning messages appeared AFTER the failure, not before, including one sent to my phone a day later.

Owner report 11721188 · 2026-02-28 (February 28, 2026)
The car’s electrical system failed while I was going at high speeds on the freeway. Red alarm notices popped up on the screen stating “check electric system”. It promptly slowed from 75+ mph to 40 mph on a major highway. My children and I could have been seriously injured. I had to then go across high speed freeway lanes at a slow speed while everyone else is driving 70+ to exit. The dealership is still identifying the issue. On the Hyundai app it shows the error code of P1A9096 which is the same error code on a recall of Ioniq cars from two …
