As the car decelerated to what my senses and perception registered as a full stop, I pressed the \u201cP\u201d (Park) button while keeping my foot on the brake pedal.  I felt the physical click of the \u201cP\u201d button under my thumb while still holding the brake, and my mind registered that the vehicle had successfully transitioned into Park. Before turning around, I visually confirmed that the vehicle had come to a complete stop. Believing it was fully secured in Park, I turned my head to check on my child in the back seat and naturally released the brake pedal completely.  However, the system had actually rejected my command. I assume that the vehicle likely still had a small amount of speed at the exact millisecond I pressed the button, and the computer automatically blocked the \u201cPark\u201d command and kept the car in gear.  Because an electric vehicle operates in almost complete silence, with no engine noise or vibration to indicate that it is still in gear, there was no auditory or physical cue to alert me that the car was moving when I released the brake. While my attention was turned toward the back seat for a few seconds, the car quietly began to creep forward, leading directly to the collision with the car in front of me.  Following the accident, I found that the vehicle produces slightly different sounds when Park is rejected and when it is successfully engaged. However, the owner\u2019s manual describes only the dashboard message and does not describe these sounds or explain how to distinguish them, so their meanings may be learned only through the failure.  At the time of the incident, I was not familiar with the distinction between these two sounds. Because my brain processed the physical press of the button as a successful action, and I had visually confirmed that we were not moving, my focus immediately shifted to my child. I was entirely misled by the digital interface.","products":[{"type":"Vehicle","productYear":"2025","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11749630,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"06/07/2026","dateComplaintFiled":"07/10/2026","vin":"7YAKRDDCXSY","components":"ELECTRICAL SYSTEM","summary":"Failure of ICCU and high voltage fuse.

The system will then disable the cruise control and lane keeping assist, creating a hazardous situation.  Alternatively, the driver can look DOWN (not looking at the road) at the DAW sensor and stare at it until the car reacts.  This takes your eyes off of the road and creates hazardous situations.  As someone who wears prescription glasses, the problem is even worse.  I cannot set a comfortable seat/steering wheel configuration where the DAW can \"see\" through my prescription glasses.  If I want to drive in my normal position, I either need to take my glasses off or turn off the safety features (e.g. lane keeping assist and adaptive cruise control) in order to drive.  Hyundai is well aware of this problem and it exists across much of the Hyundai and Kia platforms.  Dealerships say that the car is working as intended.   In reality, the defective DAW system creates more risk and contributes to a significantly less safe ride (as I'm constantly taking my eyes off the road to stare at the darn sensor).","products":[{"type":"Vehicle","productYear":"2025","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11744325,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"06/12/2026","dateComplaintFiled":"06/15/2026","vin":"7YAKRDDC8SY","components":"ELECTRICAL SYSTEM","summary":"ICCU failed with a pop sound in the evening.

SAFETY RISK: The ICCU failure caused a complete loss of vehicle propulsion, rendering the vehicle fully undriveable. Warning lamps and system fault messages appeared on the instrument cluster prior to full failure. The vehicle lost all ability to be driven or charged. A sudden loss of propulsion in a battery electric vehicle poses significant safety risk to the driver and others on the road.  DEALER AND MANUFACTURER CONFIRMATION: The failure was confirmed and inspected by the selling Hyundai dealership. Hyundai Motor America (the manufacturer) reviewed the case and issued a formal written determination in February 2026 concluding the defect was unrepairable, accepting a Lemon Law repurchase under Washington State RCW 19.118. This constitutes manufacturer confirmation that the ICCU failure is a non-repairable defect.  WARNING SYMPTOMS: Multiple warning lamps and fault messages appeared on the vehicle\u2019s instrument cluster and infotainment display prior to the vehicle becoming fully undriveable. These warnings preceded the total loss of propulsion.  ADDITIONAL NOTE: Despite issuing a written Lemon Law repurchase acceptance in February 2026, Hyundai Motor America has failed to execute the repurchase for over 23 days past document submission, missing their own stated resolution deadline.

The ICCU failure caused the vehicle to lose power in traffic and required towing. The ICCU was replaced but the 12-volt battery was not replaced.  Since that repair, the vehicle has experienced repeated electrical failures. The 12-volt battery dropped to approximately 3.5 volts on one occasion and approximately 1.72 volts on another. These voltages were measured and documented on video using multiple multimeters before any jump start or charging.  At these voltage levels the vehicle cannot unlock doors, power systems, or operate normally. The vehicle required towing by AAA.  The dealership has repeatedly recharged the battery before testing and then claimed the battery \u201ctests good,\u201d refusing to replace it under warranty.  Numerous owners online report similar failures where ICCU problems lead to repeated 12-volt battery collapse and vehicle immobilization.  Because loss of 12-volt power can disable critical vehicle systems and leave the vehicle stranded or stopped in traffic, I believe this represents a potential safety defect.   I don't have the repair reports from the dealer scanned in but I can if you want them.

On repeated mornings, the high-voltage battery was found to have not charged. The vehicle also exhibited intermittent slow charging behavior during this same period. Approximately six months prior to the charging failures, the 12-volt auxiliary battery was found to be completely discharged.  During this same period, the vehicle was started on one occasion to find that every warning and alarm indicator on the dashboard had triggered simultaneously. The vehicle was completely inoperable at that time. After several minutes, all warning indicators cleared and normal operation resumed without any intervention.  The vehicle was brought to an authorized Hyundai dealership on March 6, 2026, where the technician diagnosed the root cause as a failed Integrated Charging Control Unit (ICCU). The ICCU is responsible for managing both high-voltage battery charging and maintaining the 12-volt auxiliary battery; a failure of this component can result in loss of charging capability, auxiliary battery drain, and potentially a complete and sudden loss of vehicle operability. As of the date of this report, the vehicle is awaiting parts with an estimated repair time of approximately one week. The repair is expected to be covered under the manufacturer's warranty.

However, even though it is unknown if the water intrusion limits the seat belt's function, there is a perceived risk that this could corrode or degrade the function of the internal components due to the repeated water exposure.  The car was taken to the dealership twice. The first time they claimed they were unable to repeat the issue. However, days later it rained again and the belt and retractor were again soaked. After the second return to the dealership they were able to confirm a leak in the glass roof of the vehicle that was allowing the intrusion to the seat belt and retractor.

At approximately 6:20pm, I remotely activated climate control using the MyHyundai app. When I entered the vehicle around 6:25pm and attempted to start it, the dashboard immediately displayed \u201cStop vehicle and check power supply\u201d and \u201cCheck electrical vehicle system.\u201d The MyHyundai app reported diagnostic code PIA9096, which is widely reported by other owners as an ICCU failure.  The vehicle became completely inoperable, could not be shifted into neutral, and could not be jump-started. I attempted boosting the 12V battery and AAA also attempted, with no success. Both AAA and Hyundai Roadside Assistance refused to tow the vehicle because it could not be placed in neutral, leaving me stranded in freezing conditions and forced to abandon the vehicle overnight in a public lot.  The following morning, I installed a brand new 12V battery, which allowed the vehicle to power on, but the same electrical errors remained. The vehicle was then towed to a Hyundai dealer.  After several days, the dealer confirmed diagnostic codes PIA961C, PIA9096, and P056216 and diagnosed failure of the ICCU and high-voltage fuse. The dealer ordered ICCU assembly 36400-1XAD5 and high voltage fuse 375F2-GI040. The dealer cannot provide any ETA for parts and stated the vehicle will be inoperable until repaired. I am informed by many other owners that multi-week or multi-month delays are common for this same failure nationwide.  This failure resulted in a sudden, total loss of vehicle function, left me stranded in unsafe conditions, and made the vehicle impossible to move or tow normally.

Prior to the failure, there were no unusual driving conditions, accidents, or modifications to the vehicle. Ambient temperature was cool but within normal operating conditions.  Due to the loss of power and safety risk, the vehicle was not driven further and was towed to an authorized Hyundai dealership for inspection. The problem was confirmed by the dealer, who diagnosed a failure of the Integrated Charging Control Unit (ICCU), which manages charging and power conversion between the high-voltage system and the 12-volt electrical system.  The dealer determined that the ICCU requires full replacement. The vehicle remains at the dealership awaiting parts and is available for inspection.

All of a sudden this loud screeching noise started. It was so loud that I pulled off on the left shoulder instead of driving to the first exit. I assumed I was going to find something wrapped around an axle or wheel or dragging from the ground. There was nothing hanging from the car, so I got back onto the freeway and parking the car ASAP did a more thorough inspection of the car. I got on my hands and knees looked with a the flashlight And saw nothing. I got online and found Hyundai TSB 25-01-056H explaining that IONIQ 5 built between 12.03.24 - 3.25.25 are missing a wave washer that can cause the MGDU housing to make noise. And the MGDU needs to be replaced. I should take it to a dealer to get it fixed. I left a message with the service dept at Kearny Mesa Hyundai, where I'd leased the car on June 2, 2025. I left a VM with the Service Dept requesting an appointment and the screeching noise is my car. I made a number of recordings of the noise so I could easily provide it later. The noise stopped when I got off the freeway and hadnt started again. When I took it in on 9.22.25. They said I would have to leave the car for at least two weeks before they could look at it. They wouldn't provide a loaner because my car was built in APR/2025 after 3.25.25. The SA suggested I try another dealer for faster service. I took it to Pedder Hyundai on 9.24.25. They kept it all day and \"verified the complaint.\" My window was not fully up. I told them that this is absurd. I was told the dealer needs to verify the noise to get it fixed under warranty. On 10.19 the noise started I made more recordings & drove it straight to the dealer. They couldnt get someone to go for a ride and had to get appnt and bring it back. I took it in on 10.21 while driving there, and the noise returned.  I called the Serv Rep.

Fortunately I was in a parking lot at the time, as the vehicle limited its top speed to around 25 mph.  Had the failure occurred on a highway it could have caused a collision.  While this is a 2025 model year Ioniq 5, the ICCU hardware (part 36400-1XAA0) remains unchanged across all Hyundai/Kia/Gensis vehicles sharing the eGMP platform.  NHTSA previously issued recall 24V-868 intended to address such ICCU failures.  While the modified software is included from the factory in the 2025 model year Ioniq 5, it appears that the 24V-868 recall is not a complete fix.  Indeed, ICCU failure continues to be one of the most commonly reported owner issues, both for vehicles which have already had the \u201cfix\u201d from recall 24V-868 and for newer vehicles outside of the recall\u2019s scope.  This can be confirmed from the numerous posts and videos online (YouTube, Reddit, Ioniq forums, etc.).  Given that ICCUs continue to fail at a significant rate, resulting in reduced vehicle speed and vehicle shutdown within minutes (as soon as the 12 V battery is exhausted), I strongly urge NHTSA to do the following: 1. Consider the current ICCU software update to be an ineffective remedy for recall 24V-868. 2. Broaden the scope of recall 24V-868 or create a new recall for all Hyundai/Kia/Genesis eGMP platform vehicles to address this defect. 3. Require that Hyundai/Kia/Genesis create and deploy a truly effective remedy for this defect.","products":[{"type":"Vehicle","productYear":"2025","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11704110,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"12/08/2025","dateComplaintFiled":"12/09/2025","vin":"7YAKRDDC2SY","components":"ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM","summary":"Driving a loud bang was heard from the back of the car.

The Defect: The DAMS system is generating false positive \"Pay Attention\" warnings with an excessive, loud, and high-pitch chime multiple times per hour while the driver is clearly and actively paying attention to the road. This happens regardless of driving conditions (city, highway, sunlight, darkness) and without any valid trigger.  Safety Consequence (The Critical Issue):  This issue appears to be a systemic defect, as numerous other owners have reported the exact same pattern of frequent false warnings on online owner forums and social media groups. E.g. [XXX] , [XXX]   The false warnings create an unreasonable risk to safety in two ways:  Driver Distraction: The constant, intrusive, and erroneous auditory and visual warnings are a direct and severe driver distraction. The driver is forced to look away from the road to confirm the system status, check the camera light, or physically gesture to the camera, which is counterproductive to safe driving.  Warning Desensitization: The high frequency of false alarms leads to the driver becoming desensitized to the warning chimes. This creates a severe risk that the driver will ignore or dismiss a future legitimate warning from the Forward Attention Warning or other critical safety systems, potentially resulting in a collision.  Request for Action: I am filing this complaint to urge NHTSA to investigate this pattern of false warnings in the Hyundai Ioniq 5's DAMS/FAW system as a safety-related defect.

Purported to monitor the driver's attention by watching the eyes, this system clearly doesn't work well enough to serve it's purpose and, in fact, causes unnecessary distractions and unsafe conditions with repeated and frequent false positive warnings. The first warnings caution the driver to keep his/her eyes on the road (my eyes are on the road) and escalate to point where ACC and lane keeping assist are turned off. Since the drive attention warnings cannot be turned off when in ACC with lane keeping assist are active, the only recourse is to turn off lane keeping assist, making this system essentially non-functional and useless.  Note: Hyundai is aware of this and has issued at least one TSB advising that some eyewear may prevent the system from functioning properly and that this is considered \"normal\" leaving the driver to find suitable eyewear. I do not usually drive with sun glasses and having the car manufacturer suggest that their system may be impacted by my prescription glasses (which I do wear while driving) and the fix to this potentially dangerous situation is to replace my glasses is ludicrous. I have also done limited testing without my glasses and find that it has no impact on the false warnings. Per Hyundai's TSB I have made sure that my driver's position is such that the monitor's camera has an unobstructed view of my eyes and is not blocked at any time by my hands or arms while I'm holding the wheel.","products":[{"type":"Vehicle","productYear":"2025","productMake":"HYUNDAI","productModel":"IONIQ 5","manufacturer":"Hyundai Motor America"}]},{"odiNumber":11682918,"manufacturer":"Hyundai Motor America","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"08/25/2025","dateComplaintFiled":"08/25/2025","vin":"7YAKM4DA8SY","components":"FUEL/PROPULSION SYSTEM","summary":"I notice a strange pulsing/hesitation when accelerating at partial throttle (maybe 10-25%) between 60-65MPH.

The system erroneously triggers in all cases.  I believe that the FAW system false positives is a safety issue because: 1. The constant false alerts are very distracting, making the driver look at the panel in front of them to try to figure out what it's saying, taking their eyes off the road 2. Lane following assist is, itself, a safety feature, by disabling it due to these false positives from the FAW system, this is reducing safety in the vehicle 3. The FAW false positives will abruptly disable the smart cruise control, which is controlling the speed of the car, as well as the lane following assist, helping to keep the car in the lane.
