“Vehicle horn suddenly stopped working. Couldn't alert another driver who didn't see my vehicle and was cutting me off. Took the vehicle to the dealership who mentioned it was a safety issue and repaired the horn at no cost. Read several posts online where other Ioniq 6 drivers have reported horn malfunctions. No warning lights or messages appeared before or during the incident.”

NHTSA complaint #11635412, filed 2025-01

“I was driving on the highway, 65mph when I had a sudden loss of power, check electrical system warning and a battery picture came on. I was reduced to approx 10mph suddenly in rush hour traffic, in the left lane, with no shoulder to pull over to. I was able, with the kindness of other drivers slowing down, able to move to the right lane, then to the shoulder. Called AAA for tow to dealership. 12v battery and ICCU damage.”

“As I was driving home from work, a loud POP went off under my car, and sirens began to go off. I was given a critical error, and told to immediately contact a dealership. My car began to slow, and would only go 25 mph. Luckily for me I was within a few miles of a dealership, but if I wasn't so fortunate this would have been a much larger issue. The ICCU has failed, despite already getting Hyundai's recall for this issue performed. I am now without my car for an unknown quantity of time.”

NHTSA complaint #11684995, filed 2025-09

“I had my first ICCU recall issue, it was taken care of at Holler Hyundai in Orlando, Florida. I don't even remember seeing a recall email sent out to me, or even a call given about the ongoing recall issues. I found out about the ICCU issues from Reddit of all places, but post after post of people detailing their issues. My concern is that there's numerous post, about EV battery failure while driving or getting ready to take a trip. Imagine getting locked out of your car in freezing temperatures? …”

NHTSA complaint #11639430, filed 2025-01

“The ICCU failed on my vehicle after 25,000 miles on a 2024 model year car. Driving on a cold and wet night, after pulling away from a stop sign, we heard a large POP and then dashboard lights indicating an electrical system problem. Apparently the sound was a fuse blowing, and then the car went into limp mode. We were able to drive at approximately 24 mph for about 5 minutes before the car told us to stop immediately. We had to get the car towed to a dealership the next day, after getting it towed to our house first. …”
