What 274 owners told NHTSA about the 2025 Hyundai Ioniq 5 Bev

The driver attention warning feature is defective and often requires you to take your eyes off the road and stare at the DAW sensor in order to eliminate the car's constant "attention" warnings. Even while looking straight ahead while driving, the DAW is often erroneous and will disengage safety features (e.g., lane keeping assist, adaptive cruise control, etc.) because the DAW erroneously thinks that the driver is not paying attention. As another example, if you are driving uphill/downhill or on a curved road and are looking at the road ahead of you at a slight angle, the DAW will erroneously report that the driver isn't paying attention. 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).

The vehicle’s driver monitoring / Forward Attention Warning system repeatedly gives false inattentive-driver warnings during normal highway driving, even when I am actively watching the road and driving normally. The system does not appear to function reliably with ordinary sunglasses and common driving conditions. The issue happens frequently when wearing sunglasses. The system incorrectly determines that I am not paying attention, despite looking directly ahead at the roadway. When this happens, Highway Driving Assist and lane-centering functions may disengage or become unavailable. This occurs in normal daytime driving conditions and appears overly sensitive to environmental factors, including reflections, lighting conditions, and driver seating position. I typically receive multiple false warnings during a single drive. This is a significant safety concern because: Driver assistance features can unexpectedly disengage during highway driving. The repeated false warnings are extremely distracting and can result in drivers ignoring or becoming desensitized to alerts. There are many similar owner reports online describing the same issue with Hyundai’s driver-monitoring system. Hyundai has issued a technical bulletin describing the problem but has made no indication that it intends to fix this significant flaw. My vehicle's software is fully up-to-date.

The emergency steering will engage at random times. The car makes a loud noise, a light on the dashboard illuminates, and the car will try to drive into another lane. This happens at least once a week, and it has never happened when there was another car around, so I wasn't about to get into a collision. It has happened when there is construction and the lane markers are unclear, when the road is a little wet and other times I can't explain. I have always been able to shove it back into the lane I want to be in, but this also seems incredibly unsafe. It could drive me into any sort of situation involving other cars or off the edge of a road. I've Googled and I am not alone in experiencing this problems. I reported this twice to Hyundai customer service.

A collision occurred when the vehicle failed to detect a stationary stop‑sign pole directly in front of it. The forward collision‑avoidance system did not provide any braking assistance or intervention before impact. The vehicle is equipped with the full safety and driver‑assistance package, including camera and radar‑based collision‑avoidance features, so the system was expected to recognize an obstacle in the vehicle’s path. The failure created a safety risk because the vehicle did not respond to an object directly ahead, and the driver relied on the advertised safety features to help prevent or mitigate such collisions.

When in cruise control, the driver attention warning message appears regardless of where my eyes might be, whether I am wearing glasses or sunglasses or not, with nothing obstucting the sensor, with the steering wheel adjusted higher or lower. I have since May of 2025 tried to figure out how to get it to work properly to no avail. The warning continues to appear with an alarm ubntil it turns the motor off completely, even at highway speed causing an extremely dangerous situation. Additionally, I depend on the cruise control to help me maintain a safe, legal speed. This malfunction, rather than being a safety feature, is a distraction to safe driving. It CAUSES distraction, rather than provide safety. Hyundai is fully aware of this deficiency, yet has not addressed it I know that Many have experienced this smae problem. It is time for a recall to remedy this problem.

Have had the 2025 model for 4 months now. Absolutely love everything about it except the driver attention system. I leased this car and honestly if I can't figure out a solution there is no way I'm buying it at the end of the lease. I'm 6'1". I don't know what it is about how I have the seat/wheel situated but I get constant nags about "take a break" or "take control of the vehicle". My hands are literally at 10/2 and I'm staring into the sensor and it's still yelling at me. Today I thought the car was literally going to shut off thinking that I feel asleep or something. I also wear glasses if that has any effect on this system

I am reporting a serious safety defect involving my 2025 Hyundai Ioniq 5 (lease vehicle, brand new). While driving on a highway in Massachusetts during snowy conditions, the vehicle suddenly displayed a critical warning message “Stop and Check Power Supply” and lost power, forcing us to stop on the highway. There were two children in the vehicle, and the situation was life-threatening due to traffic speed, weather conditions, and lack of a safe shoulder. The vehicle is new and under lease, and this type of failure is unacceptable and extremely dangerous. The car had to be towed to Hyundai of Braintree, MA. This is a serious safety failure, not a comfort or convenience issue. I am concerned this defect could result in serious injury or death if it happens again, either to my family or to others. I am requesting a formal investigation into this defect.

When using cruise control the Driver Warning Alert sends visible and audible alerts (Keep your eyes on the road) even when I'm looking straight ahead, not wearing glasses, and not blocking the camera. I have tried multiple steering wheel angles and seat positions. At times I can drive for 30 minutes with no alarms but at other times it goes off every 30 seconds. This takes my attention away from my driving as I work on cancelling the alarm and puts me in a dangerous situation - exactly the opposite of its intended use. I have taken it to the dealer who claims there is nothing they can do about it even though two of their service reps told me they have the same problem. I have contacted Hyundai and they claim that the feature is acting as it was designed and refuse to fix it. On a long trip this can drive you crazy and forces me NOT to use cruise control which further takes my attention off of the road as I'm constantly monitoring my speed to avoid speeding.

Despite going back to the dealer to address the issue, and trying all the recommended modifications, the Forward Attention Warning (FAW) goes off repeatedly when the car is utilizing adaptive cruise control. I have written and called Hyundai National to ask to defeat this feature and it is not allowed. This FAW alarm (ironically) diverts my attention from driving as I am having to constantly respond to the alarm. I need the adaptive cruise control in certain situations and Hyundai will not allow me to override the FAW when the car is in adaptive cruise control. Other cars allow for this feature to be fully defeated (e.g. Toyota Prius Prime). I am worried I will have an accident because I am distracted by this alarm going off.

I turned on adaptive cruise control while on the highway and got an alert from the Forward Attention Warning system that I wasn't paying attention even though I was looking out at the road normally. The car eventually decided this meant I was unresponsive and initiated an automatic Emergency Stop in the middle of the highway. The only way I could get the adaptive cruise control to work as expected was to remove my glasses, which I need to see clearly and drive safely. I was able to disable the Adaptive Cruise Control and continue driving normally before the car stopped in the highway, but this seems like it could create a dangerous situation. After a bit of testing, I found that Forward Attention Warning system did not work with some pairs of my prescription glasses and some non-prescription sunglasses I use when I wear contact lenses. There does not appear to be a way to disable the Forward Attention Warning when using cruise control.

The car has a highway driving assist (HDA) system, but the system will not work when I am wearing sunglasses. It also has a lane assist system that is supposed to steer the car for you but it also fails and gives a message that the driver is not paying attention. The driver attention alert will not go away as long as I am wearing sun glasses. If I remove the sun glasses it works fine. Hyundai says I have to wear different sun glasses, but I have tried 4 kinds and none of them work with the system. They refuse to make any changes or repairs to the system.

The lane-keeping assistance system on this vehicle is equipped with a "driver attention monitoring system" that is meant to tell if the driver has his or her attention focused off the road. The trouble is that this system is far too sensitive and prone to very loud and distracting false alarms to the point where it becomes *MUCH* more distracting than the distractions it is meant to prevent. I almost lost control of the vehicle at freeway speeds once because the system alarmed so suddenly and loudly that it startled me. This needs to be fixed.

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.

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.

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.

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.

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.

With Adaptive Cruise control and Lane Keeping Assist on, no matter how attentive I am, within a couple minutes (give or take) I get Driver Attention warnings. These warnings are distracting and require manual intervention in traffic. I can stop them either by turning cruise control on and off, or by accelerating manually, which can be dangerous and/or inconvenient. I do sit high in the seat, as I have a long back. I wear no glasses. I have normal wide open eyes. I am keeping my hands at 10-2 orientation. I am sitting in a way that gives me clear unobstructed view of the eye tracking camera at all times. I have not had this confirmed. I understand it is a known problem.

This car has a system called Forward Attention Warning (FAW) which monitors the driver's eyes using an in-cabin infra-red camera trained on the driver. When smart cruise control and lane following assist are both activated, FAW is forced ON by the car. If FAW thinks that the driver's eyes aren't on the road, it beeps, puts alerts on the panel visible to the driver and turns off all driving assist features. The problem I'm reporting is that the FAW system is completely broken. Even though I'm looking straight forward, it says I'm not paying attention to the road, sounds loud alerts, then eventually shuts off all of my driving assistance features. I wear glasses, and sometimes sunglasses to reduce glare when driving in bright conditions, and I've tried this with my prescription sunglasses, my normal prescription glasses and even without any glasses. 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. This abrupt disabling of these systems can cause the car to slow suddenly and depart from the lane if going around a curve. This can be very dangerous.

I purchased this vehicle on [XXX] in the state of Colorado and had to drive it home through a winter storm to California. While driving home the vehicle on multiple occasion the vehicle flagged driver assist disabled or inoperable errors due to "radar blocked" stopping and checking the front of the vehicle I found that the car had no snow or ice build up on the exterior of the bumper, and there was no reason that all the driver assist and even safety features like Automatic Emergency Braking had been disabled. In addition while making this drive home, the vehicle passenger side wiper failed catastrophically. Over a 30 day process the local dealer replaced the broken wiper blade motor, and determined there was nothing wrong with the internal Auto assist system, even stating there were no DTC/ or error codes present. I provided them with images of the errors and millage, but nothing further could be done because they could not "replicate the issue" and no codes are being stored. At around 1430 miles I was driving in dry, warmer weather (around 50 degrees) when another error flashed on my screen again. I brought the vehicle back to the dealership for diagnostics, where they have yet to determine the issue again. They've stated no DTC or error codes are present, and they can not reproduce the issue so the vehicle is operating "normally and designed". I have been working with Hyundai Consumer Affairs during this entire time to help speed this process along, they have no answer other than, if the error appears again, do not turn of the vehicle, drop everything your doing in your life and bring it directly to the dealership for diagnostics (even if its active safety features are not working while your driving it).

The Forward Attention Warning system in the refreshed 2025 Ioniq 5 gives constant false positives for both my wife and myself when we are driving the car. With Hyundai's HDA and lane keep active, the system keeps chiming, claiming that the driver is not looking at the road when we are. In fact, the calibration is so poor that it is a safety issue. The constant random warnings are very distracting, and sometimes the system does not recapture your eyes before timing out and hard braking the car on the highway. This is really unacceptable and a safety issue that I'm surprised Hyundai thought it could release. Lots of evidence of other owners with this problem on the Internet: [XXX] [XXX] and many others.
