“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“ICCU failed. The car suddenly decelerated from 40mph to 25mph or less with no warning. The ICCU is confirmed to be an issue for Hyundai. I had the software update to fix the problem in 2025. It is currently at the dealership in Fort Mill, SC. DTC error code shows it as an ICCU failure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps to until the failure occurred.”
NHTSA complaint #11724865, filed 2026-03“Driving 65 on the highway, the ICCU popped and died and the car immediately went into slow mode and decreased to 20mph in traffic in the snow. It displayed a message to pull over immediately and check the power system.”
