ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
I am filing this complaint regarding Hyundai Motor America's failure to complete a vehicle repair in a timely manner on my 2022 Hyundai Ioniq 5 (VIN: [XXX] ), which has been at Hyundai of Leander, an authorized Hyundai service center in Leander, Texas, since September 2025 — more than six months — awaiting a replacement high-voltage battery. (Case No. XXX) I purchased this vehicle in September 2025 from Apple Sport Imports in [XXX] . The vehicle was sent immediately to Hyundai of Leander for an open repair and I never took full delivery. I was informed the replacement battery was initially allocated to a different dealership and a new order could not be placed until approximately January 2026. As of March 2026, Hyundai's own case manager confirmed in writing on March 30, 2026 only that they are working to determine the battery's arrival date with no confirmed completion date provided. Since November 2025, I have made 5 monthly payments of $513.92 totaling $2,569.60 on a vehicle I have never driven, with a sixth payment of $513.92 due in April 2026. I am also flagging a potential records discrepancy for NHTSA's awareness. When I checked my VIN on Hyundai's recall lookup website, Recall 272 — covering an ICCU software update, fuse replacement, and ICCU replacement on 2022-2024 MY IONIQ 5 vehicles — is listed as a Closed Campaign with a completion date of October 24, 2025. My vehicle was physically at Hyundai of Leander awaiting parts on that date and remains there today. I do not know whether this recall is related to the current open repair, but I am flagging the potential discrepancy for investigation. When I raised this with Hyundai of Leander's service department, I received no clear explanation. I am requesting that NHTSA investigate Hyundai Motor America's recall fulfillment practices and the accuracy of their recall completion records for this vehicle.

On January 19, 2026, the vehicle lost power while driving and required a tow to the local dealership. After inspection, the dealership determined that the ICCU was at fault and needed to be replaced. The ICCU part was backordered. The vehicle was inoperable for 6 weeks as we waited for the part to be available and installed.

ICCU failure occurred while vehicle was operating at 30 MPH, after being charged the night prior and unplugged in the morning at 100% capacity. A sudden pop was heard, and the vehicle indicated that an electrical fault would require the vehicle to be shut down as soon as safely possible. The vehicle went into limp mode and would not exceed 25 MPH.

ELECTRICAL SYSTEM
Car gave a "electrical error" message and would no longer charge at any charger. It slowly lost power and eventually stopped driving fully on the highway. The dealer says the ICCU is responsible. I inquired if this recall was not fixed already, they said it was but can still happen and the ICCU is not resolved truly, the software is just a temporary fix according to them. The vehicle will need a new ICCU.

ELECTRICAL SYSTEM
My ioniq 5 EV experienced an integrated charge control unit (ICCU) failure. A couple days prior to complete failure, we were unable to charge the vehicle using either level 1 or level 2 chargers. Our local Hyundai service center advised us that it was likely an ICCU failure and was unsafe to drive, due to the possibility of sudden loss of drivetrain power. The vehicle was towed to our local service center (CardinaleWay Hyundai El Monte in El Monte, California) and the ICCU completely failed after arriving at the service center. The vehicle is still at the service center and we have been advised that there is a nationwide shortage on replacement parts, with backorders of weeks to months.

FUEL/PROPULSION SYSTEM
The ICCU failed while 300 miles from home. I was unable to charge the car with level 2 charging to get home. Luckily level 3 charging still worked. The ICCU breaking can also disrupt propulsion, so I'm lucky it didn't break to that degree while driving. The dealership ultimately replaced my ICCU. There were no warning signs. In fact, the car didn't even throw a code or error. It simply wouldn't charge.

ELECTRICAL SYSTEM
The ICCU has failed for the 2nd time in a year requiring lengthy repairs. The car cannot be driven with a faulty ICCU. The ICCU is responsible for converting AC power to DC for and stepping it up to 800 volts to charge the primary battery. It is also responsible for keeping the secondary 12 volt battery charged.

The ICCU unit failed, making this electric vehicle unchargeable and therefore undriveable. This is the second time this has happened on this vehicle and the wait for the part was 8 plus weeks. This is a nationwide issue.

ELECTRICAL SYSTEM
The car would no longer charge and the dealer said it is due to a faulty ICCU. The dealer said this part is on back order with an indefinite freeze and no ETA. My car has been at the dealership shop since January 29 and Hyundai corporate has not been helpful when I escalated to them. Overall I have had these charging issues since early December. Hyundai has denied my request to buyback the vehicle since it is over 4 years old now (2022). I’m very disappointed and concerned about the ongoing ability for this vehicle to be safe and drivable.

The ICCU failed. The car is at the dealership, availability of the failed part is unknown. The vehicle was no longer able to charge the battery. This could have happened while driving. The dealership has confirmed failure and will replace when a new part is available. Unknown if part has been inspected by others. Hyundai case has been opened. There was no warning. Indication of problem was breaker tripping at charging.

FUEL/PROPULSION SYSTEM
ICCU failed at ~27,000 miles. Loud pop came from the under the vehicle. Afterwards, car could only accelerate to 35 mph. Dashboard error message told driver there was an electrical issue and advised us to pull over. Car had to be towed. Currently at the dealer awaiting a replacement. Dealership said it could take "weeks or months" to get a replacement part. Sudden loss of propulsion is a safety risk to other drivers. We were on the highway and could not get to speed. ICCU malfunctions appear to be very common with Hyundai EVs. Hyundai appears to be aware that this is a problem but doesn't seem very interested in solving it.

ELECTRICAL SYSTEM
For the past few days, our 2022 Hyundai Ioniq 5 (approx. 83,000 miles) has been unable to charge using AC charging (Level 1 or Level 2). The failure is repeatable and consistent across multiple chargers: two separate home Level 2 chargers, the Hyundai-provided Level 1 charger, and a neighbor’s Level 2 charger. In each case, charging either fails to start or stops shortly after initiating. DC fast charging continues to work normally. Component/system suspected: The problem appears related to the vehicle’s onboard AC charging system (possible ICCU, onboard charger/OBC, charge port/inlet, or related high-voltage charging components). The vehicle and components are available for inspection upon request. Safety risk: This creates a safety concern because we cannot reliably charge the vehicle at home or at most public charging locations (which are predominantly Level 2 AC). This increases the risk of unexpectedly running out of charge and becoming stranded in unsafe locations, especially where DC fast chargers are not available. Reproduction/confirmation: The issue has been reproduced on multiple independent AC chargers, making it unlikely to be caused by a single EVSE/charger. A dealer appointment is scheduled for diagnosis and confirmation. Warning lamps/messages: When attempting AC charging, the vehicle reports a charging failure/unsuccessful charging condition (exact message UNKNOWN). No prior warning lamps were noticed before the issue began (UNKNOWN). This issue appears to be widespread based on numerous similar owner reports of AC charging failure on Ioniq 5 vehicles while DC fast charging still works, suggesting a potential systemic defect in the onboard charging/ICCU-related hardware.

POWER TRAIN
There was a failure of the Integrated Charging Control Unit (ICCU) on my Hyundai Ioniq 5. We were driving home from the beach, approximately 1 mile away. When I turned the car on and started driving home, the dashboard lit up with an error and the vehicle turned on the "turtle" mode, which limited my speed. I managed to make it into my subdivision where it finally died and I was unable to get it into garage. Vehicle would not turn on, would start up momentarily, lots of errors, screen would flash, and then nothing. Very scarily, the wheels would not park and remained in neutral. This made it easy to load onto a tow truck, but scary that it could only be stopped on a flat surface. Mine and my wife's safety was at risk, as we were nearly stranded on the side of the road, I hate to imagine if this happened on a highway. The dealer confirmed our ICCU blew and we had our car back about 2 weeks later. The dealer inspected and replaced the component under warranty. This ICCU issue must be fixed by Hyundai, or at least extend the warranty. This is unacceptable.
