2023 Hyundai Ioniq 5 Complaint Log

twice this car has has experienced iccu failures. both time the car was on the road traveling when electrical system failure warning was alarm. last incident had to stop along road and towed to hyundai shop

ICCU failure. All recalls had been performed prior to failure. Vehicle showed the following warnings: "12 volt battery low", "stop safely", "check electric vehicle system", "stop vehicle and check power supply". Replaced 12-volt battery, still showing error messages, unable to be driven, required a tow to the dealer. OBD-II scan showed error P1A9096, confirmed by dealer as an ICCU malfunction.

ICCU failure, confirmed by dealer. Vehicle was parked in garage connected to charger. The ICCU fuse blew, and the house breaker was tripped. The vehicle failure also ruined the Grizzl-E EVSE (charger).

On 11/7/25 , we were driving my 2023 Hyundai Ioniq 5 to a friend's home in rural [XXX] , a trip of approximately 160 miles. At around 5:00 PM, we stopped about halfway to our destination to charge the battery. The car would not charge above 47%. While we continued to attempt to charge the battery, the console displayed a Check Electrical System Warning message, and we received the DTC P1AA700 via BlueLink. We were concerned about our safety on the drive up to the mountains. We were afraid the car would stop running on the highway and cause an accident. We were also concerned the car would die in a remote area and we would be stranded. However, the dealership was closed for the weekend. We drove carefully to our friend's home. I contacted Stevens Creek Hyundai on 11/10/25 and arranged to bring the car in on 11/11/25. It had 13,652 miles on it at that time. Eventually, the dealer confirmed the DTC P1AA700 and said they would need to order a new EGMP battery. The car was in the shop for 128 days, waiting for Hyundai to "build a battery" in [XXX] . Eventually, Stevens Creek Hyundai replaced the EV battery and I picked up the car. Given the delay in repairing my car and the growing evidence of Hyundai battery failures, we wanted to report this problem to the authorities.

I suddenly received errors that my sensors weren’t working, and I can no longer use my cruise control. The car has less than 60,000 miles so it still has the full bumper to bumper warranty. I have never had a collision. So I took it in to the dealer and they said the camera was mis-aligned and is not covered under warranty. It should be covered as I’ve never had a collision. Based on my online research, many people with Hyundai Ioniq 5s have experienced this same issue at no fault of their own, so it is a systemic problem. I took the vehicle to the Pohanka Hyundai in Fredricksburg, VA

My EV failed to charge using a home or public charger. The dealership determined that the ICCU of my Ioniq 5 failed and replaced it under warranty. I previously had evey software update and recall related to the ICCU performed, yet it still failed.

12 volt battery dead. Interior lights don't come on. Vehicle won't start. 1. 1/8/24: orange 12V light coming on repeatedly, meaning battery not charging. Dealer, Hyundai of Cool Springs, found battery would not hold charge. Replaced battery. Afterwards, orange light still came on sometimes, but dealer advised to ignore it. 2. NHTSA recall for ICCU software problem affecting battery charging, Hyundai Recall 257/021G. Dealer fixed problem 3/28/24, 41D043R0 .4. Afterwards, orange light still came on sometimes, but dealer advised to ignore it. 3. Hyundai recall #9B5 of 8/1/24, software problem in VCMS affecting battery charging. Dealer, Hyundai of Cool Springs, updated VCMS 40D097R0 .3 on 9/10/24 Afterwards, orange light still came on sometimes, but dealer advised to ignore it. 4. NHTSA Recall 24V-868 of 11/18/24, ICCU causing battery not to charge. Dealer, Hyundai of Cool Springs, updated VCU and ICCU, 40D229R0 .7 and 41D225R0 .4 on 1/23/25. Afterwards, orange light still came on sometimes, but dealer advised to ignore it.

ICCU Failure — Severe Safety Risk and Repeated Incident The ICCU in my Hyundai has failed twice. Both times, the car suddenly and completely lost power while I was driving — no warning lights, no gradual slowdown, just total loss of control. This created an extremely dangerous situation that put me, my passengers, and everyone around us at risk. When the ICCU fails, the vehicle shuts down instantly and becomes completely inoperable. During the most recent incident, I spent more than eight hours on the phone with Hyundai attempting to arrange a tow. When the tow truck finally arrived, the driver instructed me to shift the car into neutral. The moment I did, the car died again and became stuck in neutral, preventing the driver from towing it. He then left, unable to assist, leaving my disabled vehicle parked on a public road — on a hill — where it posed a further safety hazard. Hyundai’s response to these failures has been temporary at best. This issue continues to reoccur, making the vehicle effectively unsafe to drive at all times.

Car lost charge quickly, went into limp mode while I was driving on the highway. I had to pull of the road several times and try to get it to a charging station. It barely made it after the lose of power. Charged it to 80% and it would only go up to a range of 100 miles. Took it to the dealership and they confirmed it needed a whole new main battery. ICCU had already been replaced. Had to wait over 5 months for replacement parts.

NHTSA Vehicle Safety Complaint Vehicle Information: Year: 2023 Make: Hyundai Model: Ioniq 5 VIN: [XXX] Mileage: Over 137,000 miles 15 States Driven: AZ, TX, GA, CA, MI (with damage here primarily) Complaint: My 2023 Hyundai Ioniq 5 has experienced persistent and severe safety failures since delivery in January 2023, including: Complete power and control loss at highway speeds Repeated BMS/12V failures (even at 30% state of charge) Nonworking rear brake lights at night for over one year False-alarming and nonfunctional parking sensors Interior wear faster than normal; more These failures have created life-threatening hazards for me and my children, who regularly ride in the vehicle. The vehicle is under an active federal safety recall, which under 49 U.S.C. § 30118–30120 requires dealers and manufacturers to repair recalled vehicles promptly, without regard to profitability or cost. Despite repeated written requests, Pedder Hyundai (Poway, CA) refused to perform recall repairs, obstructed resolution, blocked corporate contact, and threatened to tow the vehicle illegally at my expense within 48 hours, demonstrating reckless disregard for consumer safety and federal law. A police report documenting criminal endangerment, conversion, and aggravated consumer endangerment is pending, and the lender of the vehicle has been notified of breach of contract. These issues appear systemic, affecting multiple vehicles of this model, and have resulted in: Frequent, unexpected towing with surprise expenses and downtime Significant risk of injury or death due to power/control loss Repeated failures despite warranty and recall obligations I request NHTSA investigate immediately, ensure recall repairs are completed promptly, and take any action necessary to protect public safety.

Car won't charge on Level 1 charging; it popped the GFCI in my garage and now no longer charges on level 1 (regular slow AC charging).

The ICCU failed after completing all required recalls. The car stopped working while driving. The car losing power while driving could have created an accident had I not pulled over in time. The part was replaced by Hyundai under warranty and is now fixed.

A water bottle spilled from back seat during sudden deceleration due to traffic. Thd bottle hit the back of the drivers seat and some of the contents spilled, I felt moisture from under seat on my ankles. Shortly after the car systems started reporting they were not working. By the time I returned home not even the turn signals worked and I could log turn off the EV. Car towed to desler who determined there are critical electrical connectors under the seat that showed signs of a short and corrosion. This is not covered by manufactures warranty and thd dealer presented me with an estimate over 11,000 to replace the drivers seat and floor wiring harnesses. I also filed a chain under my comprehensive insurance which was denied as the insurance company believes the corrosion was ongoing vs an all of the sudden issue. I believe the Ioniq has design flaws as critical connections should be better protected. Kids in thd back seat and front seats can frequently spill things and this fat seems way to fragile with this type of design. This problem occurred October 9th and the car is still with the dealer I need help please.

Due to a heavy brake application a water bottle in the back seat spilled and the water traveled under the drivers seat. This resulted in multiple car systems going offline, vehicle reporting LKAS error and inability to turn the car off. This essentially bricked the vehicle. Repair in order to correct the shorts and corrosion from the water both the drivers seat and main floor wiring harnesses require replacement cost estimate approximately $12,000. These key electrical connections under drivers seat are not adequately protected from simple water damage. This in my opinion makes the vehicle unfit for use as a family EV SUV as a simple water bottle still should not be able to brick a car. I consider this a design defect and the manufacturer is not covering this under warranty.

The car stopped trickle charging even though it wasn't at 100%. When I turned it on, there was a warning message indicating an electrical failure. I called the dealership and they said it was unsafe to drive it the 2-3 miles to the dealership so it had to be towed. Once it was diagnosed, the dealership told me the ICCU had failed. This is a known defect in this car that for some reason has not been resolved with the previous recalls, and the replacement units that are installed are just as prone to failure as the original. It is expected that I will have the car back approximately one week after it was towed to the dealership.

Several times now the "Check Driver Assistance System" and "Check Lane Assist System" have come on and stayed on. I brought the car dealership, and they fixed it--but only temporarily--the problem recurs within a few days of the fix. All of the sensor cameras are clean. I have read that a weak 12-volt battery can cause this problem, but the car has only 28k miles on it, so the battery should not be weak yet. I will bring the car back to the dealer (again) and have them check the 12-volt battery strength. But I am at the point where the "check system" messages are on more than they are working correctly.

Had all previous open recalls for iccu performed. No previous warning in car. Driving unto free way. Loud noise like a tire pop. 12 volt low power warning on dash screen. Car began to lose power. Picture of a turtle shows up. Low power warning. Car lost power within 10 seconds. And couldn't accelerate. Extremely dangerous. Once completely stopped the car turned off and couldn't start again. Was able to get car to turn on with jumper cables by tow truck. But couldn't get to "start" engine. Dealership says the 12 volt battery and iccu needs to be replaced. They are blaming the issue on the fact that I had an aftermarket subwoofer installed and don't want to cover under warranty. Car ran fine with said subwoofer for a year prior with no additional changes. Have used same subwoofer and amp on multiple cars with no issue.

Hyundai model Ioniq 5 (all years and trim styles) have a known issue with ICCUs (Integrated Charging Control Unit) that fail. This component controls charging of the 12 volt battery, and in turn electrical systems. Hyundai replaced my ICCU, but I am concerned it may fail again, as the underlying issue does not seem to be known or addressed. When the ICCU fails, the vehicle can suddenly lose the ability to move. This can be extremely dangerous if the car is in motion and unable to safely pull over. Luckily, my ICCU failed in the middle of a parking lot. Many Ioniq 5 owners report this issue, some multiple times on multiple ICCUs.

ICCU Unit went bad in 2025. Car totally dead. Jumped, taken to dealership, about 1 week to fix ICCU and blown fuse. A couple months later car totally dead again. Now bad battery. I am concerned about driving anywhere now. Was stranded last time it totally died. 75 year old female, should not have to pay $699 a month for iffy Ionic 5 and rent a dependable vehicle if I travel to visit friends and family.

The car would not start when start button was pressed. Warning on the dash said 12v battery critically low. This happened on three different occasions. After jump starting the car, everything works as normal. I am able to turn off and turn on again as expected. 12v battery was tested and seems to be fine. Even the OBD2 readings show battery as working correctly. There seems to be a software glitch that makes the car think that the 12v battery is low. The high voltage battery was charged to above 70 at least on all three occasions. Now I carry a external jumper battery to avoid this situation

The ICCU failed. I heard a popping noise, an error “check electric vehicle system” appeared on the dash, and i lost propulsion. I had my car towed to the dealership, where they eventually confirmed the ICCU failure.

ICCU and 12V both failed

The Integrated Charge Control Unit failed despite having all related recall repairs/actions implemented. Failure occurred while pulling into a parking place after completing level 2 charging to 80%. The failure has not yet been confirmed by the dealer, but all common symptoms match this failure including hearing a pop sound from the rear of the vehicle followed by “Check Electrical System” indication and limited distance low power, low speed mode. Had this happened while driving at highway speed, the sudden loss in power and speed could have been dangerous to respond to and get off the highway safely. The vehicle is scheduled to be inspected by the dealer shortly.

Component or System Involved: High-voltage battery system — fault code P1AA700. The vehicle is currently located at an authorized Hyundai dealership and available for inspection upon request. Safety Risk: The vehicle became undriveable due to a potential high-voltage battery failure, posing a significant risk of electrical hazard or loss of propulsion. I was advised by the dealership not to drive or retrieve the vehicle due to safety concerns. As the sole user of the vehicle in a household with children and daily transportation needs, this created a severe disruption and risk to personal and family safety, especially if the issue had occurred while driving. Confirmation of the Problem: The issue has been confirmed by the dealership, who retrieved the fault code. However, they are unable to complete diagnosis without Hyundai Corporate’s “Techline” technician, whose response is still pending as of this report. The vehicle has been at the dealership since June 30, 2025. Inspection: The dealership has begun inspection but cannot complete diagnosis or repair until Hyundai Corporate provides guidance. The vehicle has not been inspected by police or insurance, but it is under review by Hyundai’s technical assistance team. Warning Messages or Symptoms: Yes — prior to the failure, the vehicle displayed dashboard warning messages related to the high-voltage battery system, and the drivetrain became unresponsive. These warnings appeared just before the vehicle became unsafe to operate.

I bought this ioniq 5 pre-owned at 10,000 miles on 6/21/25. Clean carfax and no active recalls. One mile off the lot the system I received the message "12V battery voltage low. Stop safely." The car completely turned off. Could not put it in neutral. I was stranded on the road and it could have caused an accident. I got it towed near an auto shop and bought a new battery, thinking it was just a dead 12V battery. The car turned on and seemed to resolved the issue, but after 20 minutes of driving, it completely turned off again on the road. Very dangerous. I dropped it off at Platinum Hyundai of Tracy dealership and am awaiting a diagnostic.

The Integrated Charging Control Unit of the fully electric Hyundai Ioniq5 stopped working while I was driving my son home from the Zoo. I got a warning that there was an electrical system issue and I needed to immediately stop the car. The car lost power quickly, and I was luckily able to pull over into a parking lot and await a tow truck. This is a chronic saftey issue with Ioniq 5s and needs to be addressed.

When i was out driving with my little daughter, in the middle of the road, the car showed a warning of “check electric system”. The car was very slow and went into limp mode. I had to quickly park at a shoulder. Called roadside assistance, they sent a tow truck within 40 mns, the car was completley dead when they arrived. They had to send another tow truck that arrived after another 35 mns. I had to wait in the heat with my little daughter till they transferred us to the dealer , the repair for the iccu failure took 2 weeks. Now i am very scared each time i drive the car that this might happen again.

The ICCU failed while I was driving on the interstate, resulting in a loss of power. The car had to be towed. I waited 2 hours on the side of the freeway.

The ICCU died, causing the car to stop working while I was in traffic. This represented danger to me and my passenger, as well as other vehicles on the road. The car is currently with the dealer awaiting a new part.

Vehicle warning alarm came on with message to immediately pull over and check power supply. Towed car to dealer where ICCU and fuse were replaced. This after 1-2 recalls were completed.

The ICCU in my 2023 Hyundai Ioniq 5 failed unexpectedly, despite the vehicle having completed all applicable recall campaigns intended to address this issue. The failure resulted in a sudden loss of power, with multiple warning messages appearing on the dash (e.g., “Check Electric Vehicle System”) and the inability to drive or charge the vehicle. This posed a serious safety concern as the vehicle became disabled without warning. This issue is known among Ioniq 5 owners and appears to persist even after recall software updates or prior service actions. It raises concerns about the effectiveness of Hyundai’s recall remedies and the reliability of the ICCU hardware itself. The problem poses a potential safety risk due to the loss of propulsion, especially if it were to occur at highway speeds or in high-traffic environments. Requested Action: I urge NHTSA to investigate the continued failure of ICCU units post-recall and whether current recall remedies are adequate to ensure long-term safety and reliability.

I am filing this complaint regarding a serious safety defect in my 2023 Hyundai Ioniq 5 that occurred on 5/14/2025. The vehicle experienced a complete failure of the 12-volt auxiliary battery while parked in my driveway. As a result, the vehicle became fully unresponsive (“bricked”), and I was unable to open the passenger side front door, either of the rear passenger doors, or the back lift door. Only the front driver door could be opened manually and it had been unlocked at the time of the battery failure. I suspect that if I had locked the door prior to the battery failure I would have been locked in the car and I would have had to call for emergency help. This failure posed a significant safety risk, as passengers or I could have been trapped in the vehicle if this had occurred while on the road, in an emergency, or in a remote location. Larger or mobility-impaired passengers would likely be unable to exit safely through the narrow front passenger side if I had been able to open it. Even if I had broken the windows, it is unlikely that larger people could have escaped. There are no mechanical release mechanisms for the doors, and no clear emergency override was functional during this failure. This issue is further exacerbated by the fact that: •The Ioniq 5 relies entirely on the 12V system for door actuation and vehicle wake-up, even when the high-voltage battery is full. •There is no redundancy or mechanical failsafe for opening all doors in a total electrical failure. I have since lift wheel towed the vehicle to the Hyundai of Escondido where the 12V battery was diagnosed as faulty and replaced. The service representative acknowledged other similar occurrences and acknowledged there has been no permanent resolution or acknowledgment of the inherent design risk in such scenarios. This is not an isolated case — numerous owners have reported similar issues across online EV forums and to NHTSA. The lack of emergency door egress is a unexcusable defect.

The car lost its ability to accelerate during rush hour on a very busy interstate while I was in the far left lane. It started by jerking really hard off and on, like a very hard brake for a second, and then normal for a few seconds, and then hard braking again. I could accelerate after the "braking". There were no warnings or errors. This continued for about a minute while I was trying to decide if it was triggered by accelerating or braking, and I couldn't figure it out. At that point, I couldn't accelerate and received a number of lights and a message to check the EV system or the electrical system. I don't remember because at that point I was trying to immediately figure out how to pull over and not get hit. Luckily, it was slow enough and traffic had just thinned out enough, having passed a popular exit, so that I could coast to the shoulder across all of the traffic. I noticed at this point that the car was in neutral. I couldn't shift into drive, however. I tried to see if turning it off and back on might help. It did at that point. There were no error messages, and I could shift into drive and drive normally after turning it off and back on. Again, I wasn't concerned with documenting an error message that I assumed would be stored. The car is available for inspection. The safety of myself and my kids and other drivers around me was at risk as we could not accelerate and I was in the far left lane to the right of an express lane and left of a lot of traffic to have to cross to get out of traffic. No, the problem has not been reproduced, and it was taken in the next morning to the dealer who found nothing wrong and no stored error codes. No lamps or messages appeared before the loss of acceleration and promptly disappeared after restarting the car. Nothing was stored for the dealer to retrieve, either. The dealer ran diagnostics and found nothing wrong.

2023 Hyundai Ioniq 5 ICCU failed with DTC P1A9096 which renders the vehicle in limp mode once the 12V battery drains. This is a major issue which keeps happening even after severals recalls with software updates related to this problem. When this incident happened i had gotten all the recalls and software updates available for the entire care and still it failed prematurely at 35K miles.

ICCU failure. Car is held by Hyundai dealership for over 4 weeks, waiting for replacement part from Hyundai. Need car now. Recalls were announced in South Korea by Hyundai Group for the same part creating safety and reliability concerns for American owners.

Code P1A9096 Iccu and fuse. The car is currently at a dealer in Barre, VT. While driving numerous warning lights appeared lowering my speed to 10 MPH immediately leaving me vulnerable to a collision in moving traffic. Warning lights include "Check Vehicle Electric System", "Power Limited". Issue confirmed at dealer.

Was driving on highway and started receiving error messages for "check electrical system". Car speed dropped to max of 45mph while actively on a highway. Was able to pull off an exit but car needed a 55 mile tow to the closest dealer. Dealer has identified that the ICCU needs to be replaced but has no timeline as the item is on back order. Car is model year 2023, purchased in February of 2023 and has 22,000 miles on it.

This morning I heard a "pop" sound from the back of my 2023 Ioniq 5. A short while later a warning message appeared about the cars electrical system. A minute or two later a "Stop Vehicle and check power supply" message appeared. The infotainment screen said "A possible condition has occurred with your vehicle. A full system check is recommended TODAY." This is likely a malfunction of the ICCU. I have already taken this car in 2 or 3 times for recalls related to the ICCU, including one dealership visit within the last 30 days. As this is an electrical vehicle, electrical problems could leave me stranded. Without propulsion I would be at risk of getting hit on the highway. The same error message appeared at the service center. The car has been at the dealership all day, and I don't expect to get it back anytime soon. There was no warning of the failure before today.

The ICCU failed which prevented the car from moving. ICCU was replaced by dealer under warranty. Had to be towed from the roadway.

My vehicle displayed a Check Electrical System failure warning and experienced a complete loss of electrical power. Since it is an electric car, the car would no longer run. No light including emergencies lights worked. This happened to me in my driveway. But it happens to other owners driving down the freeway and they suddently have to pull over. Hyundai advised me to have the car towed to the dealership service center where they diagnosed an ICCU failure. This has been happening to to 2-5% of Kia and Hyundai electric cars. I was told the ICCU was on extreme backorder. I waited ~6 weeks for my car to be repaired. Note that there were two recalls for the ICCU unit previously and I performed those recalls promptly. There were no other warnings at all before the Check Electrical Systems error and sudden loss of power.

Vehicle stopped responding to all inputs while cruising on the highway. Vehicle was charged and running fine up until that point, for about 40 minutes of continuous driving. Accelerator pedal, regen paddle shifters, cruise control buttons all would not work and display was unresponsive. Vehicle slowly lost speed as if it was shifted into neutral, forcing us to pull over to the side of the road. Turning vehicle off, waiting for a minute, and turning it back on restored functions. Vehicle malfunction occurred right after a busy intersection on LA highways and we were able to make it to the shoulder, but if it had happened just 1-2 minutes earlier, we would have been in a lot of traffic merging in and out of lanes at significant speeds. There were no warning lights, messages, or auditory alerts during the occurrence. Vehicle simply lost all power. When I took it into the dealer for inspection the next day, the service staff were unable to find any issues or errors during diagnostics. Battery health was in the green and vehicle checked out fine and was released to me after a thorough inspection.

ICCU failure leading to being stranded 120 miles from home as I returned from a vacation with my family. The vehicle was working fine for half of the trip, then after we stopped for lunch, the car went into a "limp mode" max of 25 mph as I was entering the highway. I got a warning telling me to inspect my electrical system and pull over immediately. There were no warning signs. The vehicle was towed to the nearest dealer (still 110 miles from home). The dealer confirmed what happened - an iccu failure where the 12v battery was not charging - and I had the iccu replaced. This is a problem impacting many Hyundai Ioniq cars. The dealer and manufacturer was not able to tell me why it happened or what I could do to try to prevent it happening again. I have no confidence in this car

The ICCU in my car has failed twice, within an 8 month period. At each occurrence, after starting the vehicle, a loud pop was heard. The pop sound is known to be the fuse in-line with the ICCU. After driving the car a short distance, the dashboard displayed warning messages to "Check Electric Vehicle System" and to pull the car to a safe area. Fortunately, I was not moving fast and I was able to get the car safely parked within a few minutes.

4/13/25 - Check electrical system appears onscreen. Vehicle the goes in "turtle mode", not allowing it to accelerate over 20 mph. Car then shuts down and will not go into gear. I have done all service recalls as required by the manufacturer. Very unsafe and disappointed that Hyundai has not resolved this issue. All they do is update the software, they never address the actual issue. Diagnostic not scheduled for (2) days. Now I'm without a vehicle this week as they have a waiting list for loaners.

While reversing slowly, I heard a "pop" noise (sounded like balloon popping) from the rear of the vehicle, and within 15 seconds later, a "Check Electric Vehicle System" warning appeared on the dash alongside the check engine light. About 5 minutes later, I received another warning that said "Stop Vehicle and Check Power Supply" and noticed the car was losing power. Was able to get it home to get it towed, but this was within 2 months after receiving the ICCU recall for this vehicle, and it seems the ICCU has failed again.

- The ICCU assembly failed while I was driving on the highway. - The ICCU failed even after I had the car taken in due to a recall on the ICCU unit. In other words, the repair that they suggested I do to the ICCU DID NOT WORK, which means I was driving a dangerous vehicle. - When the ICCU failed, the car slowed down to 25 miles an hours and then a crawl while I was driving on the highway with my family. I was lucky to not get into an accident. - I have taken the car into the dealer and they have told me it will take up to two months to get the ICCU fully replaced because the unit in my car failed even though I had it repaired during the recall. - I have contacted Hyndai requesting they buy back my car because it is unsafe to drive. They have not responded. - YOU NEED TO GET THIS SORTED OUT ASAP. THE RECALL REPAIR ON THE ICCU DID NOT WORK AND THERE ARE OTHER CARS THAT ARE AT RISK OF FAILING.

The ICCU unit failed for the second time. The part is on back order and has not yet shipped, my car has been at the dealership for a month waiting for the part. ICCU failure has been a known issue for some time and the lack of parts to replace is astonishing.

Failure of the ICCU (integrated charging control unit) resulting in loss of power of the vehicle, failure of the 12 V battery and need to replace both the 12V battery and the ICCU under warranty. All prior recalls concerning the ICCU had been applied. This is a consistent problem with this vehicle type.

One month ago, my car experienced an failure and the warnings on the dash reported to check the electrical supply and then to stop driving the car immediately. I had it towed to a dealership who reported the ICCU failed and it'd take 1-2 weeks to get replacement parts and repair. A month later, I was just told the part is on indefinite back-order and they have no ETA when a replacement part will be available. Hyundai is selling an unsafe vehicle without that can die on the road and have no way to fix the issue. Google "Hyundai ICCU failure" and you'll see this is a systemic problem and Hyundai is doing nothing to fix these issues and is putting out 2025 models that are dying on the road with no solution.
