2024 Hyundai Santa Fe Hybrid: adaptive cruise control problems

Filed Aug 20, 2025 · Acceleration, Steering · FL

Driver Assistant cruise and steering components relating to the warning system. The system notification is turned off in the settings; however, the issue overrides the setting. Cruise control and steering assist shuts off after brief but consistant warning to keep my eyes on the road. My eyes are on the road. I can do nothing to stop it from warning. It may happen up to 20 times in a distance of 9-20 miles. This has occured since purchase and occurs everytime the car is driven. While passing on interstate highways the system may shut off. Acceleration stops, steering assist shuts off. Four dealerships have seen the vehicle and a claim was issued by Hyundai America. A Service manager finally, after many request, rode with me after a year of many service appointment resulting in a change of passenger facing camera. No change occurred in the system, it continues to behavior the same a prior to the camera change.

System keeps saying that I am not watching the road, which I am. No eye glasses or sunglasses on. This causes the cruise control to suddenly disengage creating a safety hazard. SUV is up to date on software/firmware.

Have a 2024 Hyundai Santa Fe Calligraphy Hybrid with a Drivers Attention Warning problem. The warning turns on frequently when using cruise control. When the warning beeps a few times in quick succession it actually shuts down the system, reduces speed to a crawl, and turns off the engine. This only happens while using cruise control, no issue with DAW when cruise control is off. So can't use cruise control on the highway/interstate. Dealer is no help. This is obviously a safety issue when the engine turns off while driving on an interstate. Thanks

On a bright sunny day, the Hyundai Forward Attention Warning (FAW) SHUT OFF my adaptive cruise control while doing 70 mph, indicating that I was not focused on the road. I was looking straight ahead at the road the whole time. I later determined that the system was reacting to glare on my glasses (not sunglasses, no tint whatsoever, just glass). This led to a very dangerous condition because I was fighting with the car to determine what had happened (at 70 miles per hour), not focused on the road as I just had been prior. The system is checked as OFF in setup (as described in the manual) but clearly that was not the case. The driver CAN NOT shut the system like the manual says. I actually love the car, EXCEPT for that "feature". This subsystem should never have been permitted into a production vehicle and, had I known, I would never have purchased. It's that big of a problem. The system appears to be very dependent upon ambient light because I never have this issue when it's cloudy, raining, or at dawn or dusk. I have complained at 2 Hyundai dealerships here in the Chicago area, to a total of 4 Hyundai personnel, even sent a video my daughter recorded of me driving and exhibiting the issue. In 3 of the 4 cases, they replied the "system was performing as designed". That appears to be their mantra. The one service person replied that they had never heard that before. I guess they don't ever check Reddit or write down my many complaints. I think it's clear Hyundai, as a service organization does not intend to do anything about this and, perhaps worse, the company at large has no intention of doing anything as this same subsystem is part of an extensive line of their 2025 models as well.

If am wearing my sunglasses or I am holding the steering wheel in a certain way my car will assume I am not looking at the road and turn off my cruise control. If I do not take my sunglasses off right away or move my arm my car starts breaking and alerts me to take control of me vehicle. My driver Attention setting is off. I have almost been rear ended twice because of this. Hyundai has acknowledged that is this a serious design flaw and a safety concern but has no solution

If I wear dark sunglasses, the forward collision avoidance turns off while using cruise control. If I wear lighter sunglasses, it is fine. Unfortunately, I have to wear darker sunglasses due to previous eye surgery. I am unable to utilize cruise control without compromise to my eyes because forward collision avoidance doesn’t work with darker glasses. This happens every time I test it and change sunglasses with differing shades of protection.
