ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
The ICCU unit has failed after 10 days of driving of the brand new 2025 Ioniq 5. It gave me a warning that the battery has failed while I was waiting on a signal light, and the car started limiting my speed. The car continued to get slower and slower, then it says battery regeneration failed at one point. The fastest I could go at one point was 30 mph. It was dangerous as I need to make sure the cars behind me don't come at me. When going uphill, I was only able to drive in 20mph. The car was taken back to the dealership to get serviced. They confirmed that the ICCU unit and the fuse have failed and my car will need a replacement.

AIR BAGS, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
Ioniq 5's yellow air bag wire/harness underneath driver seat has design flaw, many other owners are noticing. In my case the cables are touching the floor, it's a hazard.

AIR BAGS
Ioniq 5 is known to have a loose and possibly dangling wire underneath the driver seat. This wire is often uncovered and unshielded, and is susceptible to becoming damaged due to the automatic seats and adjustments. This wire directly operates the airbag and if damaged loses all functionality. Hyundai is not covering any damage to this wire under warranty, and this poses an immediate threat to anyone driving their vehicle.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Description of Defect/Incident Model and Feature: This complaint concerns a significant safety defect in the Driver Attention Monitoring System (DAMS), which is specifically the Forward Attention Warning (FAW) feature, on the 2025 Hyundai Ioniq 5. 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. The current behavior of the system creates a hazardous condition on the road that requires a prompt engineering solution or recall.

LANE DEPARTURE: ASSIST
The car will not allow me to use the LKA feature while wearing sunglasses. It allows it, but it gives nonstop alarms and warnings, because it can’t see my eyes? It makes the feature nearly unusable, which takes the safety feature away from the user. Even with the warning turned OFF, it still beeps. There’s literally a setting to not activate the warning, it still does it. I’ll attach a photo of the setting turned OFF. And yet it still beeps constantly. I live in Los Angeles and the sun is bright here. There must be a fix for this?

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
FORWARD ATTENTION WARNING When driving, the vehicle randomly and repeatedly warns the driver to pay attention to the road even when the driver is facing forward and paying attention to the road. The system will also randomly and repeatedly alarm, disable cruise control and apply the brakes even when the driver has both hands on the wheel and is facing forward. This has nearly caused crashes. Hyundai states the system is working as designed and suggested: 1. Driver is too tall for the system see my eyes. 2. Do not wear prescription glasses. 3. Do not wear sunglasses. Research has revealed hundreds and hundreds of similar complaints. Hyundai has issued a technical service bulletin 25-GI-001H stating there is nothing wrong with the vehicle and states drivers who are tall, short, wear glasses will experience this.

ELECTRICAL SYSTEM
I was driving the car on [XXX], and I got a battery management system warning light (DTC P0B6D00). When I got home, my car wouldn't charge. I took the car to the dealership for service for this light. Without the ability to charge and battery issues, it affects the drivability of the car and the car may stop if there isn't enough charge when driving. The problem has been reproduced by the dealer, and there was an attempt to replace a part, but it caused the light to go off 3 more times. The car has been at the dealership since June 23rd, 2025 without resolution. There were no other warnings or messages prior to this failure as the car ran without any issues.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: ASSIST
I purchased my 2025 Ioniq 5 Limited less than a week ago and have found that adaptive cruise control and lane keeping assist systems are essentially non-functional because of repeated false warnings from the Driver Attention System. 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.

FUEL/PROPULSION SYSTEM
I notice a strange pulsing/hesitation when accelerating at partial throttle (maybe 10-25%) between 60-65MPH. It's quite alarming, because it feels like the electric motor is cutting out momentarily. I notice the same pulsing/hesitation during regenerative braking at the same speeds (as with the acceleration, it is only noticeable at partial regen). The dealer confirmed that they've noticed the same behavior on other new Ioniq 5 vehicles, but they don't have a fix. I don't know the safety implications, but I worry about the electric motor cutting out and affecting my ability to control the car during acceleration or regenerative braking.

UNKNOWN OR OTHER
The Driver Attention warning activates almost every 5 minutes. No glasses are involved. I have tried many different steering wheel positions. There are plenty of other 2025 IONIQ 5 owners with the same issues as seen on forums. There is a setting to turn it off but it does not turn it off.

POWER TRAIN
I leased a 2025 Hyundai Ioniq 5 with the exact same issue. The VIN is [XXX] My new Hyundai Ioniq 5 is having the same problem again! Vehicle will hesitate/shudder and pulsate at highway speeds. Between 57mph and 78mph seems to be where I can feel it the most. This happens on all drive modes and with or without brake regeneration turned on or off. Nothing seems to make it worse or better. Here is an example. If you are driving 65mph on the highway and holding your speed steady, the car motor feels like it's cutting in and out. Juddering forward and back. If you accelerate a tiny bit, it gets ever worse. It feels almost like the input signal from the peddle is choppy, causing the car motor to judder. It is a forward to back motion. Not a vibrate or side to side motion. Dealership said basically they'll keep the car and possibly we can hope Hyundai will lemon law me out of the car.

I took the car to the dealership where they confirmed they could feel it too. They ended up rotating my tires... Said that's all they can really do because Hyundai doesn't have anymore information. They basically said sorry but they can't help.

ENGINE
I have had my new car only two weeks and have driven only 500 miles. Yesterday, while driving on a freeway at constant 65 mph speed, I suddenly experienced COMPLETE POWER FAILURE. I coasted across three lanes of heavy traffic and came to a stop on the shoulder. There were no warning lights on the dashboard. I turned the car off, turned it on again, and the car drove normally. I checked on my Hyundai app and it said under Vehicle Health that all systems were normal. I called the Santa Monica Hyundai service center and was advised to drive home to Santa Barbara (on the freeway) and get in touch if the problem recurred. I drove my car some 50 miles to Santa Monica to be evaluated and the service rep said that all makes of EVs have this problem, not unusual. After some hours, I spoke to the shop foreman who said he had never seen this problem, that the diagnostics had shown no problem, that there was no indication that this had indeed happened, that he could do nothing further unless there was proof that I had experienced complete power failure, and that if it happened again I should obtain proof by videoing the dashboard and my foot pressing down on the accelerator without any response. I called the Oxnard Hyundai dealer where I had purchased the car and was advised to bring my car there for a second opinion. I drove the 60 miles to their service center. I was told by the service rep that he had never heard of this problem. I was given a loaner car to drive the 40 miles home and my Ioniq 5 was kept for evaluation. I discovered on Google that sudden power failures in Ioniq 5's are a known problem by both Hyundai and the NHTSA and that there have been recalls as a result. It seems reprehensible that Hyundai representatives in two different dealerships claimed that they had never heard of this phenomenon. I was at risk of a potentially deadly accident by losing power on a freeway. I am lucky to be alive.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: WARNINGS
You cannot wear dark sunglasses while driving this car, as the safety systems are turned off because the car fails to recognize your eyes, as it can't see them through the sunglasses. How does the research and development side of making this ioniq 5 not see this? This ultimately forces you to drive without sunglasses, causing an unsafe environment while driving. This is a bad design for the car.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: ASSIST
Car constantly gives false alarm that driver is not looking at road. It’s particularly bad with sunglasses or even normal glasses, but false alarms are common even without glasses in strong sunlight. It’s a serious safety issue because the car constantly beeps false warnings and threatens to disable driving assistance. Internet forums are full of users reporting same issue, this component is defective.
