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 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?

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.
