The shift-by-wire system failed while the vehicle was being parked. The vehicle would not shift out of Drive; repeated attempts to engage Park resulted in Neutral only, with a "PARK malfunction. Engage parking brake when parking vehicle." warning displayed in the instrument cluster. Because this vehicle requires Park to be engaged before it can be powered off, the vehicle also could not be turned off. I was trapped with an energized vehicle that could not be secured in Park or shut down for approximately 30 minutes. A red 12-volt battery warning lamp was illuminated in the instrument cluster during the event (photo attached showing the malfunction message, Neutral gear state, and battery warning lamp). I secured the vehicle using the electronic parking brake. Safety risk: a vehicle that cannot engage Park or power off risks rollaway and leaves the driver unable to safely exit and secure the vehicle, particularly on a grade or in traffic. This is the second occurrence of a shift-to-park failure on this vehicle. The vehicle was previously taken to an authorized dealer for the same symptom; the dealer cleared diagnostic codes without repair and the problem recurred. The vehicle is scheduled for further dealer diagnosis and is available for inspection upon request. The ICCU recall remedy (Recall 272) was previously completed on this vehicle per the manufacturer's campaign records.

While driving on the highway, there was a complete loss of power and steering. I was able to navigate to the side of the road. The vehicle would not start on multiple occasions, and no warning lights illuminated. The vehicle was taken to the dealer, where it was stated that the issue could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the issue. The approximate failure mileage was 18,000.

In November of 2025 the vehicle displayed a "Check Eletrical System" error message. Shortly thereafter the vehicle decelerated to under 10mph as we were turning into traffic. We were able to drive it home (less than 1mi away) and then called the Dealership. The car was then towed to the dealer (but needed a jump as the 12v battery had drained). The dealer diagnosed a failure of the ICCU and replaced it. The vehicle was in the shop for approximately 2 weeks. More recently, on May 3rd of 2026, the vehicle experienced a complete deceleration as it was traveling through an intersection. No error lights or warning messages were displayed. I was only able to partially clear the intersection before the vehicle came to a complete stop. At this time the vehicle would not allow itself to be put into neutral so I could not push it out of the intersection. After approximately 5min of attempting to move the vehicle, it once again began responding to accelerator requests and I was able to drive it home. It is now with the dealer and I await their response.

On March 19, 2026 my Hyundai Ioniq 6 broke. It was clearly the ICCU problem. The car went into turtle mode with a maximum speed of 22 miles an hour and told me to get to a safe area , stop the car and have it brought in. It was brought to my local Hyundai dealer and a few days later they confirmed it was the ICCU problem. This is a safety issue. Fortunately I was 1 mile from my house and did not get stranded. Hyundai has had four years to fix the problem and obviously they have not done so. The car was a 2023 with about 23,000 miles on it.

I leased a 2023 Ioniq 6 electric car on September 2023. Since leasing the vehicle, the vehicle has been towed four times for the same problem, the parking brake malfunctions rendering the vehicle unusable. I have multiple photos and videos documenting this. This has happened either after parking the vehicle and attempting to turn it off, or after turning on the car after being parked. The first three times this happened the vehicle remained in neutral and would not change into any other gear. The car would not turn off or lock. The last time it happened again the car stayed in neutral and would not change gears, but I was still able to turn it off and lock it. Below is a summary of all the times the car was towed and how many days it was in the dealer. 1.December 12, 2025 (towed to dealership #1) to December 19, 2025: 8 days, no action taken, unable to find the cause of the problem 2.December 20, 2025 (towed to dealership #1) to December 29, 2025: 10 days, no action taken, unable to find the cause of the problem. Note the car failed again the day after it was returned to me on December 19. 3.January 2, 2026 (towed to dealership #2) to January 13, 2026: 12 days.

Subject: Safety Complaint – Sharp Upper Door Edge Causing Facial Injury (Hyundai IONIQ 6, 2023) Message: To whom it may concern, I would like to submit a safety complaint regarding my 2023 Hyundai IONIQ 6 (VIN: [XXX] ). On October 14, 2024, my wife suffered a facial injury caused by an extremely sharp upper edge of the front door. This occurred in our driveway at [XXX] . The injury happened when the front door stopped at its mid-detent position and the sharp, exposed upper edge made forceful contact with her forehead and the area next to her eye. She avoided a direct eye injury only due to quick reflex. This design presents a serious risk to passengers, especially those of shorter stature. I have photographic documentation showing the sharp door edge and the injury mechanism. Hyundai Motor America was informed, but they dismissed the case and advised us simply to “be more careful.” They offered a $150 virtual compensation card, which I did not use, because accepting it could be interpreted as accepting their proposed settlement. Hyundai insisted on dealer inspection, which is irrelevant because this is not a defect of a single unit — all vehicles of this model have the same door-edge geometry. I believe this is a safety-related design hazard affecting all Hyundai IONIQ 6 vehicles. I respectfully request that NHTSA review this case, as the risk of eye or facial injury is significant. Please let me know if you require additional information or photographs. Sincerely, [XXX] [XXX

March 21st at around 7:30 PM, I was driving on the highway when my panoramic sunroof suddenly exploded—or shattered—completely out of nowhere. It was a clear night, no rain or debris, and there were no cars directly in front of me. Nothing hit it—no rocks, no objects—just a loud bang, and the glass was gone. I’ve got photos of the damage (attached), and it’s clear this wasn’t caused by an external impact. The glass blew outward, which makes me think it’s a manufacturing defect or stress in the material.

The driver seat is causing back, glute and groin pain. The car has been driven for only 1.7k miles, but the seat cushions already have so much give that one can easily feel the frame under the seat when sitting or pressing down with an open hand. The back of the seat has so much give that it is possible to feel the plastic behind the seat back cushion. I will include photos, but unfortunately it is rather difficult to capture the issue in photos. The issue is constant and ongoing. Aside from causing pain that is requiring medication, the uncomfortable seating is distracting and experiencing numbness in your legs while driving are both clear a safety concern. The dealership, as well as Hyundai USA’s customer service, are refusing to take any action on these concerns. Instead they have given me the run around for 4 months saying I should contact customer service or the dealership, respectively. The dealer has inspected the car, but maintains that there is no issue. I would be happy to get the car assessed by somebody independent if NHTSA as suggestions in that regard. The issue first became apparent after driving the car for daily commutes shortly after taking possession of it.

Forward Collision Avoidance › Automatic Emergency Braking1 injured
Filed Feb 20, 2024OH

On the afternoon of February 12, 2024 (5:12pm), I was driving northbound on I-71 at highway speed, approximately 75mph. My Hyundai Ioniq 6 alerted me of a (non-existent) impending front-end collision, and within 1 second of the alert starting, the automatic emergency braking system activated. This resulted in the violent (and unexpected) braking of my car to around 25mph. There was no clear reason for the collision detection alert or the automatic emergency brake. The light was good and there was no significant weather. There were no vehicles immediately in front or behind me. (Nearest car in front was over a quarter mile away.) The force of the braking was sufficiently strong that I am still sore in my shoulder and back a week later. I am fortunate that there wasn't a car close behind me, as I likely would have been rear-ended due to the unexpected and abrupt nature of the braking. The vehicle was taken in for service (invoice attached) and "calibrated". Within 10 miles of getting back on the highway, warnings (but no braking) triggered again. (photo attached of one of the warnings). The vehicle is currently back at dealer service.

Vehicle Speed Control
Filed Feb 20, 2024FL

While driving in the highway I took my foot off the accelerator and despite one pedal driving being on the car did not brake. I then tapped the brake. When I then pushed the accelerator to keep up with traffic, nothing happened. I checked the screen for warning lights. The car had none. The accelerator pedal was non responsive causing a huge safety issue for me and others on the road as the car was now just cruising as I was approaching a hill..I had to turn on my hazards and get over into the shoulder of the highway along the bridge at night. I stopped the car. There were still no warning lights on. I turned the car off and back on and the problem was no longer present.

Back Over Prevention › Sensing System › Camera

The contact owns a 2023 Hyundai Ioniq 6. The contact stated that while reversing, the brake lights interfered with the optics of the back-up camera. The inference caused the camera image to be distorted which affected the visibility while reversing. There was no warning light illuminated. The contact stated that the failure persisted. The vehicle was taken to the dealer to be diagnosed; however, the vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 3,518.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
