The ICCU in my Hyundai Ioniq 5 failed catastrophically today ([XXX]) after only 3109 mlles. I believe this to be the case because: • I heard a loud pop from behind me in the car. • The car immediately lost power and would only go very slowly. • An alert about the electrical system immediately came on and told me to stop driving as soon as possible. • A rather loud alarm sounded. • DTC P1A9096 appeared in my Bluelink app. All these point to a failed ICCU. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The ICCU chip failed. This chip communicates between the propulsion battery and the smaller, traditional 12v battery. The chip failed, and the car thinks the propulsion battery is dead. This is very common occurrence I have learned, the ICCU chip is continuously on back-order.
ICCU FAILURE. Went to start vehicle (at full charge) and warning light came on "Check Battery Health". Wouldn't move, got towed to service center. Diagnosed as an ICCU failure. Car is 6 months old, 9,400 miles on it.
Battery electrical system, car gave warning to stop and park immediately , and stalled in the middle of the street while trying to make a turn, with no way to move it, or put it in neutral.
While driving in traffic I heard a loud pop coming from the rear of the vehicle. A warning light came on on the dash board and the vehicle immediately slowed to about 10 mph. This was a dangerous situation as I was actively passing a vehicle on the highway and could have ended up colliding with oncoming traffic!
ICCU failed during drive. Eventually died in the middle of the road. Took a month to fix

On [XXX] my there was a loud pop from the rear of the vehicle and electric vehicle warnings popped up on my dash. I turned around at the light, and as I drove I could tell that the vehicle was slowly losing power. Speed was limited to 30mph. Barely made it back home before the warnings on the dash told me to immediately stop driving. Vehicle was towed to the dealership, and they informed me on January 8, 2026 that the ICCU had went out and blown a fuse, so they needed to replace both. The car is unable to be driven until this is replaced. The current odometer reading is 3,390 miles. I called yesterday, January 21st and was informed that Hyundai has the ICCU on backorder and it will be at least two weeks before they can update me again. I've reached out to Hyundai Motor America National Consumer Affairs. They stated: 1) No recall exists for this issue and claim this is only impacting 1% of vehicles. 2) The supply of ICCUs was depleted in December 2025 and have been on backorder since. 3) There are no plans to redesign the ICCU to prevent failures so this could very well happen again, and as there are no indicators as to what causes it to malfunction it is making the vehicle unreliable. They have 'escalated' this but I likely will not get the vehicle back for a few more weeks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
