2025 HYUNDAI IONIQ 6 Recalls, Complaints & Safety

"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 are currently at the dealership and available for inspection upon request."

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 dealer has not been able to promptly resolve the issue. This appears to be a broader safety-related defect rather than an isolated incident.

I TOOK POSSESSION OF THIS VEHICLE ON SEPT 1, 2025 SINCE DAY 1 THE BLUELINK APP STATES THAT THE CAR NEEDS SERVICE I SPOKE TO HYUANDI CUSTOMER SERVICE & THEIR ONLY RECOMMENDATION IS THAT I GO BACK TO THE DEAL / I SAID TO THEM JUST YESTERDAY (FEB 12, 2026) SO LET ME GET THIS STRAIGHT / AM I SUPPOSED TO GO BACK TO THE DEALERSHIP EVERY DAY I THINK A RECALL IS NEEDED TO SEE WHAT IS GOING ON WITH THESE HYUNDAI CARS MY ORIGINAL CASE # IS XXX

THIS CAR WAS PREPPED BY COCONUT CREEK HYUNDAI AND I AM BEING TOLD BY YOUR CUSTOMER SERVICE DEPARTNEMTN THAT THERE MIGHT HAVE BEEN SOME DEBRIS ON THE WIPERS THAT CAUSED THE SCRATCHES / HOW IS THAT MY FAULT HYUANDI HAS WALKED AWAY FROM ANY RESPONSIBILITY / IN FACT THEY ASKED ME IF I CHANGED THE WIPER BLADES / I JUST GOT THE CAR 5 MONTHS AGO WORST CUSTOMER SERVICE

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.

Battery is not charging to full capacity. The ICCU has been replaced and the battery is still not holding a full charge.

My car horn has ceased to work. I have not taken it in to be fix yet, but feel it is a safety issue.

this vehicle was delivered to me on Sept 1, 2025 / i have been back to the dealership a few times regarding the front windshield is totally scratched up this had to happen from the windshield wipers the issue is that when i drive into the sun the glare from all the scratches is annoying the second issue that hyundai cannot fix is that the app on the phone has stated since day 1 that the cars vehicle health needs attention / hyundai corporate response is that I should take it back to the deal EVERY DAY / i have no clue what is wrong with the car and if it is safe to drive hyundai corporate is washing their hands regarding both of these issues / they are doing the same thing now that they did to me in 2018 when they told me that I had to pay them to break a lease on a lemon law claim when they could not fix the 20+ issues that were wrong with my car i have case numbers if you want them

The ICCU died and the fuse on my traction battery blew. Both had to be replaced. I realized I had the problem when I started my car and it showed "Check Electric Vehicle System". When I tried driving it, I was limited to speeds below 45MPH, then eventually 25MPH, and eventually it would enter "turtle mode" and I could limp along at a couple MPH. I found the car would no longer charge the 12V accessory battery and it would no longer receive a charge from my home charger.

My car is less than a year and a half old with only about 10k miles and last night I had the ICCU failure. I already had the software update to "fix" this safety recall 272 but it obviously didn't work. I am a female with a young daughter who was almost stranded in a bad neighborhood as suddenly my car wouldn't go faster than 15 miles an hour and I looked it up and knew it would just stop suddenly at some point. I only had a quick 1 min warning when I turned on my car that said "Check Electrical Vehicle System" then switched to "Stop vehicle and check power supply". My car is now at the dealership and I was told they have to put the same type of part back in as there are no new versions of it. Which is why others have had this happen multiple times.

ICCU failure which causes a fuse to pop. Because it is an EV the car cannot be driven

Warning came on the dashboard to check electrical and stop driving which I did and started up the car again and was only able to drive another minute until the entire car lost power while trying to accelerate and I had to have an emergency pull off into a strip mall off of a busy street car was towed although the Hyundai Road assistance did not know that the dealer they towed to was not able to work on electric vehicles, and therefore had to be restored. At this time, I was told it was an ICCU issue. The part was ordered, and I am waiting to hear back from the dealership.

-ICCU failure, identified by dealer service department as the cause of catastrophic failure. -The car suffered a catastrophic failure on a 2-lane country road in Princeton NJ on [XXX] at approximately [XXX] at night in 20 degree temperatures. Every function except blinkers (temporarily functional) ceased to work. I waited in the car, without heat, for an hour before service arrived. The car could not be moved and was left in the road until 3:00 am, when the towing company I paid towed the car to my driveway a mile from the failure site. -My safety was at severe risk while I waited in the car. -Dealer replaced ICCU assembly with the same part, with the possibility of repeated failure. -Warning messages appeared somewhat over a mile before catastrophic failure. The car slowed to 11 mph. -Hyundai has known of the potential for catastrophic ICCU failure in their electric cars since 2022. I took possession of this 2025 model in March 2025. I was never informed of any recall, although it appears that a recall was issued at the end of 2024. -Hyundai has denied compensation for irresponsibly, with knowledge of the potential failure, subjecting me to a hazardous, life-threatening situation. -Anecdotally, of the 4 Ioniq owners I know, 3 have experienced ICCU failure.

While driving "check electrical system" warning appeared and vehicle went to limp mode limited to 20mph while on a 40mph roadway. Drove an additional few miles to try and reach home and vehicles completely died, no power. Towed to dealer. DTC P1A9096 indicates ICCU failure

ICCU Failure

I leased the 2025 Hyundai Ioniq 6 in April of 2025, in November of 2025 the car charging time started to increase when using L3 charging stations. The normal charging time would be 15 minutes for the battery to reach 80% capacity and an additional 30 minutes for the battery to reach full capacity. After November it took 20 to 30 minutes for the battery to reach 80% capacity. On January 2, 2026, I was charging the car at a L3 station and when charging was completed the car no longer worked. The car displayed the message “Please unplug the charger to start the car.” But the car was not plugged in. I tried to trouble shoot for 20 minutes and had to call a tow truck for the car to be towed to Hyundai. The car sat at the Hyundai dealership for a week with the battery power draining from even though it was not turned on nor was it drivable due to the error message. According to the Hyundai website, there was an open recall on this car for the ICCU, and I show no record of this issue being fixed for this car prior to leasing it. The car is at the dealership still and has not been repaired.

It is the ICCU (Integrated Charging Control Unit). The car lost power while I was going up a steep hill with a car behind me. The Hyundai dealership technician stated it is the ICCU (Integrated Charging Control Unit), and according to him, "We have ordered a replacement ICCU and FUSE. No eta on special order parts." The dashboard gave me the following message with a red battery symbol: “stop vehicle and check power supply.” In researching the VIN on the HYUNDAI SAFETY RECALLS AND SERVICE CAMPAIGNS website I learned that servicing was done on November 22, 2024 addressing this issue when it had just 19 miles on it. The Closed Campaign states: Recall 272, 2022-24MY IONIQ 5 (NE EV).2023-25MY IONIQ 6 (CE EV), 24MY IONIQ 5 ROBOTAXI (NERINTEGRATED CHARING CONTROL UNIT (ICCU) SOFTWARE UPDATE, ICCU & FUSE REPLACE. If my vehicle is repaired using a replacement ICCU that is of the same design, which has contributed to numerous failures, this does not instill confidence in their solution. I request that something be done to force Hyundai to FIX THE PROBLEM by identifying what is actually causing the ICCU to fail, and come up with a real solution, rather than a bandaid that needs replacing every so often.

The ICCU assembly and high voltage fuse blew/broke at 6,255 miles as I was driving on Interstate 294. That immediately reduced the vehicle maximum speed to about 25mph, causing a hazard to myself and following drivers who were traveling at 55mph or more. I limped about 3 miles to the next exit, where Hyundai arranged for a tow and warranty service to replace the faulty parts. There were no prior symptoms or warnings. As this is both a known, ongoing (several years)Hyundai issue and apparently unrelated to driver behavior/practices, perhaps an NHTSA query will inspire Hyundai to actually resolve this issue instead of simply replacing the part(s)?

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 repaired. There should be more recalls.

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 on the title record and misrepresentation of ownership sequence. The matter is under review by the Texas Department of Motor Vehicles (Case #25-XXX) and other state agencies for related title and notary irregularities, but the mileage falsification falls under federal odometer regulations. I am submitting this to NHTSA to request review of potential violations under 49 U.S.C. §32705 (Disclosure of Mileage Upon Transfer) and 49 CFR §580.5–§580.8 (Odometer Disclosure Requirements). Supporting evidence, including the certified TxDMV title history, Progressive repair estimate, and Hyundai diagnostics..

Crash

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 another car. My car is brand new and I've had it for about 1 1/2 months. It is a 2025 Hyundai Ioniq 6 SEL that was manufactured in 2024. The car has it's original tires from the manufacturer Hyundai. The tire is defective and was not safe to drive. I contacted Hyundai corporate and the dealership about this and they did nothing to reimburse me for the defective tire. I not only am still working for compensation for the tire that was $400 after taxes and fees, but I am trying to alert Hyundai about safety of this model tire.

We were not informed of the recall in a timely manner. Discovered it online and called dealer to make appointment. They would not give us an appointment for about 3-1/2 weeks and we were told we have to leave the car for 4 to 5 hours. Notification we eventually got later stated repair would take 30 minutes. The dealer provides no transportation to or from, so it means waiting there for 5 hours or paying a service to drive us home and back. This is inexcusable. The car is brand new and repair is supposed to be free. It would cost us $100 in transportation to and from if we do not wait for it. If this is a safety issue, we should not have had to wait so long for an appointment. That is NOT timely.
