2026 Hyundai Ioniq 9

Driving on a public road with a 50 phone speed limit, I received an error message on my dash stating electrical failure, and then the car shut down and began to coast, I had use all my strength to turn the car towards the curb and coasted to a stop. I received an error message from multiple components and then the dash went blank.

On 8/3/26 my Ioniq 9 had a warning message to Check the Electrical System, but provided no additional information. I was able to drive the car home, anticipating that I be able to take it in to the Hyundai dealer where i purchased the vehicle. It should be noted that the car went into limp mode (max 25 mph) for the final six miles to my home. I researched the issue on line and determined that it was possible to get the car to the dealer based upon the experience of other Hyundai owners. Note: There was no information in Hyundai documentation as to the range i could expect once receiving the error message. The morning that I took the car to the dealer, the car started normally but within 1/2 mile it went into limp mode again and within 100 feet went into 'turtle mode" 2-3 mph and came to an abrupt stop. I was at the side of the road and put the hazardous flashers on (which remained on for only a matter of minutes before going dead). The vehicle was then totally dead with no emergency flashers on a busy street). I had the vehicle towed to the dealer which was returned later in the day noting that "the 12 v battery had been recharged and subjected to load and GDS diagnostics, both passed. ICCU inspection confirmed no faults, no parasitic current draw detected, ECR reset performed". Got the car home and the very next morning received a code indicating that electrical service was required. Took the car back into the dealer and have just been informed that the ICCU is being replaced. Safety concerns: lack of documentation and information from mfr, a dead vehicle on a well-travelled road with no functioning safety hazard flashers. Luckily the event occurred during daylight hours and not during the nighttime hours.

I am submitting this complaint regarding a suspected manufacturing defect involving an original equipment Hankook iON evo AS tire installed on my 2026 Hyundai IONIQ 9. At approximately 8,000 miles, and with the vehicle only six months old, the tire developed a severe vibration that increased with vehicle speed, becoming most noticeable above approximately 55 mph. The vibration became progressively worse, raising concerns about the safe operation of the vehicle. A Hyundai dealership inspected the vehicle and determined that the sound-deadening foam attached to the inside of the tire had separated from the tire carcass. The detached foam caused the tire to become significantly out of balance. The tire required replacement. This was not the result of a road hazard, impact, puncture, or normal tire wear. The tire had been used under normal driving conditions and had accumulated only approximately 8,000 miles. Because the vehicle could not be safely driven until repaired, I was required to rent another vehicle while awaiting the repair. Hyundai denied reimbursement for the rental expense because tires are covered under the tire manufacturer's warranty rather than the vehicle warranty. I am concerned that separation of the internal foam on original equipment Hankook iON evo AS tires may represent a manufacturing defect that could affect other vehicles equipped with these tires. A severe imbalance at highway speeds could create a significant safety hazard by impairing vehicle control or distracting the driver. I respectfully request that NHTSA review this issue and determine whether similar failures have been reported and whether further investigation is warranted.

An Integrated Charging Control Unit (ICCU) failure halts the vehicle’s ability to charge and power the 12-volt battery. When it fails, the car can no longer keep the 12V battery charged. This drains the 12V system, potentially causing a sudden loss of motive power while driving or a "bricked" car that won't start. The presents a safety problem because it happened while I was driving and the car slowed down to a halt in a high speed traffic area. This is a well known issue with Hyundais and Kias that share the same EV platform. The car was towed to the dealer on 7/21/2026 and was confirmed as an ICCU issue after diagnostics.

ICCU failure. Warning lights came on in the dash and diagnostic codes were available in my Hyundai app. My family and I had just gotten back from a road trip and if the ICCU would have failed while we were on the trip we would have been stranded and it would have been during the heat wave. The vehicle is currently in the service department waiting for the part to come in.

My 2026 Hyundai Ioniq 9 (Performance Calligraphy AWD), leased new in late April 2026 from Team Hyundai of Bend, OR, suffered an Integrated Charging Control Unit (ICCU) failure at approximately 1500 miles in late June 2026, roughly two months into ownership. The failure progressed over several days. First, at a ChargePoint Level 2 (AC) station, the vehicle repeatedly displayed "charging started" every few minutes in a continuous start/stop/retry loop. Within days, AC charging failed completely: the vehicle reported "charging unsuccessful" on two separate EVSEs (a hardwired Level 2 charger and the Hyundai portable charger) across two different circuits. DC fast charging still worked. No other dashboard warnings were displayed. The dealer diagnosed a failed ICCU and replaced the unit. The vehicle was out of service for approximately 2 days thanks to the dealership's great service team. Luckily we were not out on a road trip which we have planned in the next 2 weeks which would have left us stranded with a newborn. This is a documented, ongoing safety defect across Hyundai, Kia, and Genesis E-GMP vehicles. ICCU failure can cause the 12-volt battery to stop charging, leading to reduced power or sudden loss of motive power while driving, which creates a crash risk. NHTSA previously opened an Office of Defects Investigation into this issue, and Hyundai issued recalls 24V204 and 24V868 to address it. What makes this report significant: the 2026 Ioniq 9 uses the second-generation ICCU that Hyundai represents as containing the corrective hardware changes. My failure occurred on this redesigned part, on a vehicle barely two months old, which indicates the underlying defect has not been resolved in current-production vehicles. This is the family's primary vehicle and we have a newborn at home, so the loss of use was a significant hardship. I am filing so this second-generation ICCU failure is on the record and counts toward any future investigation or recall action.

The motorized flush door handles lack an automatic anti-pinch resistance sensor when retracting. If an object, hand, or child’s finger is caught inside the door handle while the vehicle locks, the motor continues to force the handle shut. This creates a severe crushing and entrapment hazard. This is available for inspection upon request. My child’s finger got caught in the door handle while the vehicle was locking. There have also been several near miss incidents. The problem has been reported to my local dealership where I purchased the vehicle, but they do not appear to take the issue seriously. The issue has not been inspected by the manufacturer, police, insurance representatives, or others. There are no warning lights or messages due to this issue.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.
