Hyundai Motor America (Hyundai) is recalling certain 2022 Ioniq 5 vehicles. A software error in the Shifter Control Unit (SCU) may disengage the parking mechanism, which can allow the vehicle to rollaway.

The Dealer states my ICCU has failed and will be replaced. My vehicle could no longer charge on AC power (level 1 or level 2), and eventually had to be taken to the dealer because it could not be charged at home any longer due to the ICCU failing.

I have had multiple issues believed to be related to the ICCU. The first issue was that my 12V battery deteriorated and died prematurely. I had to purchase a jump start charger and ultimately replace the OEM 12V battery in 2024 (within the first 2 years of owning my new vehicle) because it was failing to reliably start and I was at risk of being stranded every time I parked and turned off my vehicle. The 2nd issue occurred in Dec 2025 - the vehicle stopped charging with L1/L2 chargers. The deal

While making the short drive to work on surface streets I was given a warning in an amber circle to check the electrical system. Moments later I was presented with a warning in a red circle reading "Stop vehicle and check power supply"; accompanying this warning was a drastic loss in power. Had I been on the highway I would not have been able to maintain speed with the likelihood of being stranded in an unsafe location. The dealership reported that the ICCU (internal charge control unit) had fai

While driving on the highway during a rainstorm, the high voltage fuse on my car's Internal Charge Control Unit blew and the ICCU itself failed. This rendered the vehicle inoperable as soon as I managed to get it to the shoulder. It took two weeks to repair, and I had to argue with Hyundai's corporate lines for almost six months before the offered a partial reimbursement for their device failure.

The ICCU failed. This was verified both by my local Hyundai dealership, Conicelli, and Hyundai Corporate. My safety was put at risk because my car rapidly lost power, informing me to pull over now while I was in the middle of driving. This happened with no other warning. The component has been inspected by the manufacturer, and I had even received a recall already that was supposed to prevent this issue from happening. There were no prior warning signs other than the alert to pull over now, whic

My car is one of many Hyundai Ioniq 5 vehicles that has experienced an ICCU (Integrated Charging Control Unit) failure. This results in a car that is not drivable, and generally needs to be pulled over within a few miles, as it no longer can be driven above about 35 mph. It also will no longer charge on AC charging (level 1/2), since the ICCU is needing to convert AC -> DC to charge the main battery. This is a very well-known problem that Hyundai is addressing in only a piecemeal fashion. He

ICCU Failure . Car stopped in the middle of the highway. I was able to move over thankfully to the side of the rode. Went into turtle mode and then it had to be Towed to my local Hyundai Dealership

P1A9096 ICCU failure ICCU Failed while travelling on interstate. Limp mode limited vehicle to 40MPH top speed. 12V battery was not able to recharge. Became a slow-moving hazard while driving back home a few miles limited to 40MPH during winter conditions. Problem was confirmed by dealership service center No other warnings prior to sudden "pop" and dashboard warning to check EV electrical system.

The Integrated Charging Control Unit (ICCU) has intermittent failures. During the last failure, my wife was on a busy freeway (Interstate 5 near Hwy 120 northbound) in heavy but fast moving traffic. She was driving in the #2 lane (of 4 lanes) when she experienced sudden loss of propulsion. The vehicle slowed to 5 MPH in traffic that was moving 70 to 80 MPH. She had to traverse through the #3 and #4 lanes to the narrow emergency shoulder. Cars were honking and flipping her off. In the emerg

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 is

My vehicle recently experienced issues charging. It would not charge using a Level 1 or 2 charger, but would allow limited Level 3 charging. After having the vehicle inspected by a Hyundai dealership, they confirmed that the ICCU had failed for the vehicle.

After pre warming the car in the garage, I left for work. Three minutes into the drive I heard a single popping sound from the passenger side rear of the car. I then received an error on the dash "Stop Vehicle and check power supply". I them drove 4 more miles to work with the hazards on. Two hours later I attempted to drive it to the dealer and it stopped .5 miles away. Hyundai had it towed the rest of the way.
