2024 Hyundai Santa Fe: adaptive cruise control problems

Filed Nov 6, 2026 · Driver assistance · IN

Since delivery in May 2024, the driver-assistance systems on my 2024 Santa Fe malfunction in rain and snow at highway speeds, around 65 mph. The cameras report being blocked and a cascade of alerts goes off: warnings to put my hands on the wheel when they already are, "take a break" driver-attention warnings, and "conditions not met" messages. Smart cruise control shuts off without warning, and lane assist loses the lines. About two months ago (around September 2026), driving in pouring rain, the car flashed a message that it was shutting down while I was on the road. The date entered is approximate. The driver-attention camera also gives constant false warnings in normal driving: when wearing sunglasses, with an arm resting on top of the steering wheel, or with dust on the camera. Both drivers in our household experience this. Sudden alarms and systems shutting off at highway speed in bad weather are distracting and dangerous. I reported this in writing to the dealer in February 2025, saying the safety features had nearly caused numerous accidents, especially in bad weather. The dealer offered to show me how to turn the features off, but that never happened, and nothing has been repaired. My daughters were usually in the car when these events happened.

I have had the vehicle in 4 times for check forward attendition warning system light keeps coming on. The first time they replaced the front camera. The situation came back after I was using the cruise control on a express way. Did not do it do it on the road but as soon as you stopped and turned the vehicle off the vehicle check forward attention warning system would come on and off and the only way to shut it off was to stop from more than 20 minutes and it would reset. Took the vehicle back 3 times and they could replicate so there was nothing they could do. The issue came back today. The check forward attention warning system light keeps going on and off. We stopped and let the vehicle sit and upon restarting the check forward attention did not reset . This time the vehicle lost all volume from the dash board. You could recieve phone but no volume. No radio volume. All the safety features that Bing are not working. Check the set up and the volume had a red 🔺️ next to the volume. 4 times into the shop for the same issur

Hyundai - DAW - Driver Attention Warning / Forward Attention Warning System This issue warrants immediate consideration for a recall. Despite wearing glasses, sunglasses, or no glasses, the problem persists. I occasional do remove my glasses while driving, and the warning continues to sound. This occurs regardless of the time of day, weather conditions, or whether I am sitting upright or reclining. The warning randomly activates and deactivates, sometimes without any intervention. Occasionally, I simply allow the warning to sound without taking any action, and it remains active for a few seconds or until it triggers a warning that the system will be turned off, at which point it deactivates. I have attempted various troubleshooting methods, such as keeping my eyes open, adjusting my seating position, wearing and removing my glasses, and tilting them to minimize glare. None of these methods have proven effective in preventing the warning from activating or in making it deactivate. This is a persistent problem. Hyundai dealerships initially informed me that the warning might be an annoyance and their response was to simply refrain from using it. However, if a basic feature like cruise control in a 2024 & 2025 model is rendered unusable due to a design flaw (which this certainly is), it constitutes a clear violation of safety standards and should be addressed through a recall. The incessant alerts are highly disruptive and can be quite frustrating. For instance, driving with an arm in the 12 o’clock position triggers a warning, while wearing polarized sunglasses also results in an alert. The presence of a setting to disable the warning is a welcome feature, but the system’s persistent alerts can be overwhelming. The alerts continue even after taking a break. It is distracting and a safety hazard. Drivers should be able to adjust the sensitivity of the feature to turn off this feature. Currently, there is no way to disable or temporarily disable this feature.

when using lane following the system repeatedly warns you to pay attention, usually when in heavy traffic and after repeated warning shuts of the cruise and lane following system. when using the cruise control system the system will suggest you take a break. both problems appear to be associated with an in cabin camera. i have driven my vehicle almost 25,000 miles and taken two cross country trips. the warning system has almost never warned me of a real problem. 99 percent of the time it is a false reading by the camera and occurs under challenging driving conditions when the last thing you need it to be told to pay attention when you truly are. during this winter i have driven more at night and the vehicle is basically un drivable because of false notifications. this has repeatedly happened in the 14 months i have owned the vehicle - the date below is just for when it happened today. i am more than willing to share details and would welcome a call

The drive attention warning system turned off the cruise control. Causing the vehicle to unexpectedly decrease speed on the interstate, which forced the cars behind me to brake hard to avoid hitting me. This system is constantly giving alerts for no reason distracting my attention to the road. I can have both hands on the wheel and looking straight forward and the system gives an alert tone and flashes a message on the screen stating it can see my face. If the cruise control is on it will disengage the cruise. If the cruise is not engaged it just keeps alert every 20 miles or so. I have taken it to the dealer, who showed me how to turn it off , but it still alerts over and over again.

The Adaptive Cruise control cannot be used while wearing certain sunglasses. The car has a Driver Awareness Warning that is supposed to warn the driver if eyes are not on the road. It does not work with certain glasses. While driving at interstate speeds, I engaged the Adaptive Cruise control only to have it shut off and quickly slow down. After fumbling with different glasses while driving, I found a pair that will work with the Adaptive Cruise control. In the display, there is a toggle to turn off the Driver Awareness option, but as soon as you turn on the Adaptive Cruise, the Driver Awareness turns on again. If the Driver Awareness function cannot be turned off it is a safety issue. My favorite driving glasses cannot be used and I think this issue will cause accidents with the quick slowing on the highway. There should be a way to turn off the Driver awareness so I can use the adaptive cruise with my sunglasses.

The Forward Attention Warning device located on the steering column (camera) cannot be disengaged. This device does not allow me to wear dark or polarized sunglasses, which I need since I have eye issues. This is a safety issue for me and others, especially since I am [XXX] [XXX] and there are times when the visor doesn't cover the sun. You can 'disengage' it in the Driver Assistance settings but it does not stop the warnings nor does it stop it from disengaging your cruise control. If you look to the side of the vehicle, look up to pull the visor down, or wear polarized or dark sunglasses, it will also shut off your cruise control. I have taken the vehicle in to the Gainesville GA Hyundai and told them about this issue but they have said that there is no fix for this. BTW -- there are a bunch of posts on Reddit about this issue. This problem isn't a failure of the system, it is a design flaw. I noticed it on the day I bought the vehicle. Now, it is an annoyance to the point that I am looking at buying a new vehicle. I have only had the vehicle a year....not happy.

The cruise control uses a camera , the is supposed to watch your eyes , to make sure you are watching the road . Unfortunately , if you are wearing glasses ( which I must when I am driving ) the light reflecting off them makes the unit think I am not watching the road . For backround, I was a highway patrol offiger for 30 years . I am very attentive to the road ahead of me . It seems hyundai knows of this problem , which suddenly disengages the cruise control , causing rapid deceleration of the vehicle . At highway speed , this is very dangerous . It has been noted on many forums , and my dealer knows about the problem , but there is no way to disconnect the camera from the system . This is really an accident waiting to happen .

This vehicle has a Driver Attention Alert System which track driver's eye and head movement to determine driver attention levels. This system can be disabled outside of using Cruise Control through the setup menu. However, when in Cruise Control, this system CANNOT be disabled. Unfortunately, if you're wearing sun glasses the system declares the driver is inattentive and produces a distracting aural and visual warning. If no action is taken the vehicle will automatically come to a stop, even on the freeway! This option is a driver distraction and does not allow the driver to wear sunglasses increasing the risk of motor vehicle accidents. Several customer have complained to Hyundai about this system. there needs to be driver-selectable option to enable/disable, even in Cruise Control mode.
