2025 Hyundai Ioniq 5 Lane departure Problems

“The Lane Keeping Assist works well and is very useful. Unfortunately it is combined with the infrared eye monitor system, which is very flaky and does not work well with prescription glasses when sunlight comes in from the front or side. It provides many false warnings, but cannot be turned off without losing the Lane Keeping Assist. If I drive without my glasses, it works fine, but it seems counter-productive to make me lose a good functioning system by tying it to a flaky not-useful monitor.”

“FORWARD ATTENTION WARNING system incorrectly detects a driver's lack of attention when I drive wearing sunglasses consistently. Many times it will incorrectly detect lack of attention while not wearing sunglasses. The camera has perfect line of sight to my eyes. Turning the system off through the Driver Assistance features does not stop the problem. It drives me crazy and I'm unable to identify any solution to this problem and I have learned this is a very common problem with this year and model.”

“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. …”

“While using Highway Driving Assist/Lane Following Assist on Interstate highways, lane markings frequently disappear on overpasses and in construction areas. When this occurs, lane-centering assistance silently disengages. The only indication is a small dashboard icon changing color. There is no audible warning, steering wheel vibration, or other prominent alert. The vehicle may begin drifting before the driver realizes steering assistance has been lost. Observed repeatedly on Massachusetts highways, including I-495 and I-290. …”

“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?”
