2025 Hyundai Ioniq 5 Collision Avoidance Problems

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.

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.

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.

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.
