SEAT BELTS

2 injured

Two safety incidents occurred (October and November 2025) involving the power-folding second-row seats. A child was seated in the second-row captain’s chair when a sibling activated the seat from the third row. The seat failed to detect the occupant and continued moving forward, creating a crushing hazard. In one incident, my daughter (approx. 40 lbs, 46 inches tall) was partially trapped and screamed as the seat compressed her and/or tightened the seatbelt. I had to intervene to stop the mechanism. I later tested this myself and confirmed the issue is reproducible. While seated, the seat continued moving forward and pushed me into the front passenger seat without automatically stopping.

SEATS

1 injured · 12,000 miles

The contact owns a 2026 Hyundai Ioniq 9. The contact stated that the second-row seat button caused the seats to fold; however, the button that should have prevented unsafe operation was missing. The contact’s head became lodged between the seat and the vehicle structure, and he sustained head injuries, including prolonged headaches and trauma. No medical attention was provided. There were no warning lights illuminated. The local dealer was not contacted, and the vehicle has not been diagnosed or repaired. The manufacturer was notified, and a case was opened.

STRUCTURE:BODY

1 injured

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

NHTSA complaint 11745506, quoted in part. Filed by an owner and not verified by NHTSA or by us.

FUEL/PROPULSION SYSTEM
On XXX I had two warnings pop up on the car to check electric vehicle system while driving. The car was still driving fine, so I took it into the dealer (ALM Hyundai in [XXX]) within a few days to have general maintenance and for the DTCs to be reviewed. The EV tech was 2 weeks out, so they just briefly reviewed the code and said it was safe to drive. Everything was fine until XXX. I fully charged the vehicle overnight on XXX. Around 11:30 a.m. on XXX I went to drive the car. This was the 3rd time I had driven it since charging it and was about 2 minutes into the drive when the check electric vehicle system light came on again and the car started losing power and accelerating on its own. It

ELECTRICAL SYSTEM
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.

NHTSA complaint 11756108. Filed by an owner and not verified by NHTSA or by us.

ELECTRICAL SYSTEM
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

NHTSA complaint 11755299, quoted in part. Filed by an owner and not verified by NHTSA or by us.

WHEELS
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.

NHTSA complaint 11752973, quoted in part. Filed by an owner and not verified by NHTSA or by us.

ELECTRICAL SYSTEM
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.

NHTSA complaint 11751977. Filed by an owner and not verified by NHTSA or by us.

ELECTRICAL SYSTEM
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.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
