2025 Hyundai Ioniq 6 owner complaints

The ICCU had a failure and fuse also blew; vehicle needs those parts replaced. After reading about ICCU recalls, my vehicle was not in the last recall. It affected 2023-2025 models I started up my car in morning and was about to reverse out of my driveway. I heard a pop near the rear of my vehicle and then saw a "Check Electric Vehicle System" warning and battery light indicator on my dashboard. I tried driving around for a couple of minutes around my area, the car would not accelerate over 20-25 mph. I returned home and looked up the issue. My Hyundai app showed a Diagnostic Code of DTC P1A9096, which is related to the ICCU. I already have my car at a local Hyundai dealership to get it repaired under warranty but if it wasn't, I can only imagine the price it would cost to get this repa

"While driving a 2025 Hyundai Ioniq 6 at approximately 10,000 miles, the vehicle experienced a sudden, catastrophic Integrated Charging Control Unit (ICCU) failure with no advance warning. The vehicle instantly experienced a total electrical shutdown while the car was on the ramp. The failure completely bypassed and disabled standard safety redundancies: the electronic parking brake/emergency brake system failed , and the 12-volt backup battery died instantly, making it impossible to activate the hazard lights. The vehicle became a completely invisible, immovable dead weight on an active roadway, presenting an imminent, extreme threat of crash, injury, or death to myself and surrounding motorists. I was holding my breath and have to call AAA road side emergency assistance, only when an ext

The contact owns a 2025 Hyundai Ioniq 6. The contact stated that while reversing out of the garage, the vehicle suddenly stalled, with the message "12-Volt System Deactivated" displayed. The vehicle was towed to the local dealer, where it was diagnosed and determined that the computer control module had failed and needed to be replaced. The contact stated that the computer control module failure was caused by using a faulty phone charger inside the vehicle. The computer control module was replaced, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 300.

I was driving at 60mph. I heard a sudden pop that felt like it came from behind me / under the car. While I glanced to see if I ran over something (I did not), the car suddenly felt like it was about to stall. It was slowing down quickly and dramatically. My safety was in danger as I quickly dropped speeds in heavy traffic on a freeway without warning. I was able to maintain control, and I turned my hazards on. I noticed that I was maintaining speed around 35-40 mph (no matter how heavy I hit the accelerator), and I moved to the right lane and continued while wondering if my car would survive all the way home. Luckily I was only about 1 mile from my house at that point, so I proceeded at a low rate of speed and ultimately made it home. It was scary, sudden, and put me and others on the r

On April 10,2026 I heard a pop while driving and a check electrical system light came on, my vehicle lost power while driving. This appears to be a common problem with ioniq5 and 6 going back years. Also failure in their ICCU and 12 volt batteries.A veh. Losing power unexpectedly could lead to a collision, injury or worse.my Ioniq 6 was recently serviced and only has 14,794 miles.I respectfully urge the national highway traffic safety administration to: 1.continue and expand investigation into electrical system failures in the Hyundai ioniq 6 and 5. Also 2. Ensure that affected vehicles are properly repaired with permanent solutions or the company should have to buy back the unsafe defective vehicles. Also 3. Require clearer and more immediate warnings to drivers regarding the risk of sudd

On the evening of February 11, 2026, my 2025 Hyundai Ioniq 6 SEL experienced a complete ICCU failure while I was traveling with my minor son. The vehicle became fully inoperable and left us stranded on the side of the road at night, in the middle of a winter storm. I was forced to call for a tow truck, wait in dangerous conditions, and arrange emergency transport for myself and my child. The vehicle was towed to Visions Hyundai of Henrietta, located in Rochester, New York. That was over three weeks ago. As of the date of my complaint, my vehicle remains at the dealership. I have been told that the replacement ICCU part is on indefinite backorder, with no estimated delivery date provided. I am left making full monthly payments on a vehicle I cannot drive.

ICCU failure. Sudden total electrical shutdown. According to this site, there was a recall filled but NOT COMPLETE since November 2024! We are now February 2026. There has been NO warning issued to Hyundai consumers about this. When the ICCU fails, it puts consumers at risk. When it happened to me, there was no shoulder to pull onto. Because there was a snowstorm that morning, the flatbed tow truck did not come for 3 hours. My car was in the shop for 3 days. The bottom line is that the failure of communication about this defect puts consumers at risk!

My leased 2025 Hyundai Ioniq 6 experienced a sudden malfunction resulting in loss of vehicle operation. The vehicle has been at the dealership with delayed diagnosis and no clear repair timeline provided. This appears to be a safety-related defect involving the electric system. I am aware of multiple reports and recent news coverage describing similar failures in Hyundai/Kia electric vehicles related to ICCU (Integrated Charging Control Unit) defects, which can cause sudden battery discharge and loss of propulsion. Media reports indicate that this defect has affected numerous vehicles and, in some cases, repairs have taken more than a month due to part availability and diagnosis delays. My vehicle experienced similar symptoms, including loss of power / inability to operate normally, and

The car displayed “Check Electric Vehicle System”. The 12‑V battery stopped charging. The vehicle could not be driven very far or very fast. The car had to be towed to a Hyundai dealer.The ICCU was diagnosed as failed. The ICCU has been an ongoing issue with Hyundai EVs.

I am reporting an odometer and title discrepancy involving a 2025 Hyundai Ioniq 6 (VIN: [XXX] ) purchased from Van Hyundai II LLC (Carrollton, TX) on January 6, 2025. The dealer issued two temporary tags with conflicting color entries and later reported the vehicle to the Texas DMV as having 57 miles at title assignment. However, the vehicle was involved in an accident on January 17, 2025, and the official Progressive Insurance repair estimate and Hyundai diagnostics (app data) both record approximately 535 miles at the time of loss. After the loss, the dealership and insurer (Progressive) processed a title transfer using the original Manufacturer’s Certificate of Origin (MCO), listing Progressive as buyer with $0 consideration and 57 miles. This resulted in a false odometer declaration

NHTSA COMPLAINT — SHORT VERSION I am reporting a persistent, unresolved, safety-related steering defect in my 2025 Hyundai Ioniq 6 (leased 10/12/2024). Beginning in September 2025 at approximately 15,412 miles, the vehicle exhibits: (1) uncontrolled steering wheel shifting left and right at highway speeds; (2) hard pulling to the left when accelerating or decelerating; and (3) the vehicle swaying or jerking within its lane without driver input. I described the issue to the dealer as "pretty dangerous to drive" — this language is documented in Repair Order #XXX. Despite 6+ documented repair attempts over 9 service visits from September 2025 through May 2026, the defect remains unresolved. Repairs attempted include: two 4-wheel alignments, road-force balancing, steering angle sensor calibrat

"While traveling in fast-moving traffic, my 2025 Hyundai IONIQ 6 suffered a catastrophic electrical system failure and an immediate loss of motive power. The vehicle instantly entered a 'limp mode' and dropped to a maximum speed of 11 mph, creating a life-threatening hazard for myself and surrounding drivers. There were no warning lamps or symptoms prior to this sudden failure. The vehicle was towed to a certified Hyundai dealer (Ricart Hyundai), where a diagnostic scan confirmed a failure of the Integrated Charging Control Unit (ICCU) with error code DTC P1A9096. This failure is directly related to the known issues in Recall 257. The dealer has confirmed that the replacement ICCU is currently on indefinite backorder with no estimated time of arrival (ETA). The vehicle and failed component

My car was parked and I noticed that there was a bump in the sidewall of my vehicles driver front tire. This is the 2nd time this has happened in a month with factory installed tires that came with the vehicle when purchased brand new. I have had my 2025 Hyundai Ioniq 6 SEL since 12/13/2024. I already submitted an NHSTA safety ticket on 2/3/2025 due to my driver rear tire exploding while driving. Ticket # 11640496. This is extremely dangerous and can kill myself or someone else on the road, especially on highways. There is a defect in these tires that Hyundai had partnered with Pirelli to install on brand new Ioniq 6 SEL vehicles. I am lucky I caught the bump on the side of the tire before it exploded while driving. I have attached the pictures of the tire from this 2nd incident.

Pirelli 245/40 R20 99W The driver rear tire had blown out on me as I was merging onto a highway. I heard a heard a loud pop sound and the car shook and I had to swerve back into my lane. I looked around me and there were no objects or pot holes. My tire emptied down to 7 PSI in about 5-10 seconds. I immediately pulled over to the side of the road. I inspected my tire and there was no damage to the exterior of the tire (nails, screws, debris, etc.), as well there was no scraping of the tire or abrasion. When the repair tech took off the tire to replace it he noticed the steel belt had separated on the tire and had protruded from the inside out and caused the tire to blow. This was extremely scary and dangerous. If there would have been a car to my right my car would have crashed into an
