While driving at highway speeds on freeway, the vehicle suddenly presented warning message, "Stop vehicle and check power supply". Immediately after the warning appeared, the vehicle experienced a rapid loss of propulsion and entered a "limp mode", gradually losing power over the course of a few minutes as it limped into a safer location to wait for tow services. The sudden loss of drive power on an active freeway put the safety of myself and other motorists at risk, forcing me to navigate the vehicle off the roadway and onto a side street at an extremely low speed. The vehicle was subsequently towed to a certified Hyundai dealership. The dealership reported that the vehicle's battery was completely drained, leaving the car entirely unresponsive and unable to turn on. The dealership is currently inspecting the vehicle and has requested additional time to diagnose the root cause. The vehicle and its components are available for inspection.

Stuck in gear or won't shift by model year
What owners say
ICCU failure at 6,126 miles. Vehicle went into limp mode and had to be towed.
Vehicle unexpectedly ceased to work. A loud pop sound then a message to check electrical system. Vehicle reverted to “limp mode” leaving me at a max of 15 mph. Terribly unsafe and extremely, concerningly widespread ICCU failure across Hyundai EV models For 5+ years is unacceptable
ICCU unit of the car short circuited right in middle of driving and caused the car to go in "limp mode". Sudden pop noise and slowdown created situation where car could be rear-ended. The part has already caused recall for prior model years, but model year for my car is not included in the recall. Based on internet search it is a continued and widely prevalent issue, manufacture has not done enough to fix this and a recall needs to add new model years. Additionally, the parts are backordered and there is no immediate fix.
ICCU fuse blew during operation, car went into limp mode. Vehicle is currently being serviced under warranty through Hyundai
Car suddenly went into limp mode while driving and completely vehicle shutdown soon after. It has been diagnosed at dealership that it is ICCU issue. It would be very dangerous if this happens on highway.
ICCU unit failed in parking lot leaving us stranded. Over 30 days to repair. Common issue. Luckily we weren’t on the road as the vehicle goes into a very short limp mode which may not allow time to get off a busy highway.
The ICCU failed under normal utilization The vehicle went into limp mode which changes expected driving dynamics The dealer confirmed ICCU failure and the manufacturer has confirmed the vehicle is a lemon as per MA state law No warnings prior to the failure
The vehicle was in the middle of a u-turn when the ICCU fuse suddenly and without warning blew. Display warning messages came on to "check electrical system". Car was able to drive in "limp mode" at about 40 mph on level roads, but not more than 25 mph on any uphill. This is a well known problem with Hyundai EVs. It will be towed to a dealer to confirm. It felt extremely unsafe to be in the middle of a turn on a public street and have the car power system fail. Luckily there was minimal traffic at the moment. A few minutes earlier or later would have been on a heavily trafficked road
ICCU unit failed on 1/27/26, vehicle entered limp mode and is unusable. This is affecting thousands of Hyundai Ioniq 5 autos, and probably others as well. Due to the widespread problem, Hyundai is unable to give an estimate on finding a replacement part.
ICCU failure. Vehicle has 5200 miles on it. A loud "pop" was heard then the vehicle went into "limp mode" and restricted speed to 30 mph. After about 10 miles the car totally lost power and wouldn't start. Warning l messages said to get it serviced which is what I was attempting to do.
The vehicle experienced a sudden failure of the Integrated Charging Control Unit (ICCU). While driving, a loud "pop" was heard, followed immediately by a "Check Electric Vehicle System" warning on the dashboard. The vehicle then entered "Limp Mode" with significantly reduced propulsion. The 12V battery became depleted, leading to a complete loss of motive power and loss of electronic safety systems, creating a hazardous situation in traffic.
