Adaptive Cruise Control problems of the 2025 Hyundai Santa Fe

Dear NHTSA team, my car was in a minor accident last. After that, the repair shop replaced my bumper and front camera. Don franklin somerset Hyundai performed a calibration on my new radar. They calibrated it six times, but there are still many issues with the hda driving system. 1. False dual-side warning when a vehicle is present only on the right side, the vehicle camera system incorrectly detects vehicles on both the left and right sides. In reality, there is no vehicle on the left side. In this scenario, both the radar warning and the camera detection are incorrect. 2. Wrong-side warning in some cases, when a vehicle approaches from the left rear, no warning is issued on the left side, while a warning is incorrectly displayed on the right side. In this scenario, both the radar warning and the camera detection are incorrect. 3. False warning during Smart driving while driving on the highway using the Smart driving function, when the vehicle is required to turn left or right, the system may generate a false dual-side warning. As a result, the vehicle aborts the intended left or right turn and continues driving in the center of the lane. In this scenario, both the radar warning and the camera detection are incorrect. 4. While driving manually (without hda engaged) or parking, the vehicle shows left-side or right-side collision warnings without clear cause. I reported these issues to Hyundai USA approximately three weeks ago. I was instructed to bring the vehicle to the dealership for inspection. However, during my recent visit, the dealership representative only reviewed the videos I provided and concluded that no issues were present, without conducting a physical inspection or test drive of the vehicle. Given the ongoing safety concerns and lack of proper diagnosis or resolution, I am submitting this complaint for your review and assistance. Thank you for your attention to this matter. Thanks, best regards, [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5.

This car was in a bbb binding arbitration and Hyundai was told to fix: speed control malfunction, speed linit not posting to hub arbitrary fan engagement. The dealership alm west had the car 2 weeks and the car sat on their lot. They said we are unable to duplicate the problem. Now in addition I showed them the cracked windshield and they were not responsible. I had an insurance complaint I took it to safelite and replaced the windshield yesterday and I got it back with a new windshield and it also had a crack in the replacement windshield. I think Hyundai knows there's a problem with the glass which is also part of the safety system of the car.

I am reporting a safety hazard with the driver monitoring/driver assistance system in my 2025 Hyundai Santa Fe sel (VIN: 5nmp2dgl5sh096694). The system frequently misinterprets my normal driving behavior as inattentiveness and triggers constant, loud beeping while I am driving. In many cases, it also disables assistance functions mid?drive, which is dangerous and unexpected. The false alerts appear to be caused by the system misreading my eyes due to their natural shape and size. This issue does not occur with my wife, who has larger eyes, which indicates the system is biased toward certain physiologies and does not reliably detect all drivers. I have tested this repeatedly: if I strain my eyes unnaturally wide, the alerts stop, but this is extremely uncomfortable and only sustainable for a few seconds. The system is effectively pressuring the driver to adopt unsafe, unnatural behavior to avoid constant alarms. Environmental conditions such as sun glare, rain, and darkness make the false alerts even more frequent. The sudden loud beeping is startling and forces me to divert attention from the road. The unexpected loss of assistance features during driving further increases the risk of an accident. This system is not functioning as an assistive feature. Instead, it creates distraction, encourages unsafe compensatory behavior, and fails to accommodate normal variations in driver physiology. I request that NHTSA investigate whether Hyundai’s driver monitoring system meets safety and reliability standards and require corrective action if necessary.

The adaptive cruise control does not allow the use of sunglasses to be worn while the cruise control is engaged. The cruise control will immediately shut off when sunglasses, and some prescription glasses are worn. This is a safety issue as you are not allowed to wear sunglasses on a sunny day or when the sun is low in the sky and it is below the car's sun visor. The same camera that is looking at the drivers eyes also controls other safety features and disables them when the driver is wearing their sunglasses, and some prescription glasses as well.

Wearing any kind of polarized sunglasses prevents you from seeing the heads-up display and will abruptly disable the adaptive cruise control. The Santa Fe forum has hundreds of complaints about this, yet Hyundai has not done anything to correct the problem. I have asked three different dealers about this problem, and they just repeat the company line (you need to find sunglasses that don't cause a problem). This situation is dangerous and unacceptable.

I just purchased a 2025 Hyundai Santa Fe and the Smart cruise control won't work with sunglasses on. There is an infared sensor on the steering column that has to see your eyes. Sunglasses are needed for this vehicle. If you don't wear them, the sunlight blinds you. The system will beep, display a message stating full face can't be seen, and it shuts the cruise control off and the vehicle decelerates, which is unsafe.

The driver assistance warning system continuosly goes into shutdown mode. Eye monitoring system always states that you are not keeping your eyes on the road. I have tried using different glasses or no glasses. Changing the steering wheel settings also seem to have no effect. This is very dangerous as it will start decelerating and stopping in the middle of a freeway in heavy traffic when this warning is activated. This only happens with the lane keeping assistance and adaptive cruise control are on. Hyundai issued technical service bulletin 25-gi-001h, but they did not solve the problem.

Vehicle unable to recognize face when wearing sunglasses and disables all driver assist aids, including turning off the cruise control.

Hyundai's forward attention warning is so aggressively annoying it makes me want to drive off a cliff to shut it up. Driving with an arm in the 12 o'clock position? "beep! keep your eyes on the road!" polarized sunglasses? "beep! I can't see your eyes!" OH, there's a setting! let's turn it off. . . "beeeeep! where are your eyes!". I just purchased and cannot use cruise control I need to wear glasses it has a hard time seeing my eyes I cannot turn off I have tried many positions on steering wheel to no avail.

The attention detection system is the worst designed feature of any vehicle I have ever experienced. It constantly dings while looking directly at vehicles ahead. It is distracting and turns off by looking down directly at the steering wheel. It is a safety hazard and Hyundai needs to push out a fix ASAP or allow the feature to be disabled entirely. You cannot use cruise control without it activated and the feature is a safety hazard that makes the car less safe.

I purchased a new 2025my Hyundai santafe hybrid. Since the day of my purchase there has been a constant error message that is displayed on dash saying "driver attention warning system failure". This light stays on constantly and disables cruise control and adapative cruise system. This affects the usability of the vehicles. When asked Hyundai they say, drivers arent expected to wear sunglass if this system has to work properly, they even say constant blinking will cause system to fail and disable cruise control. This is a serious concern. How can people drive a car without blinking and how can a new car have disabled cruise control all the time.

We purchased a 2025 Hyundai Santa Fe caligraphy VIN [xxx] in July 2025. During a road trip the following week when we got on the interstate and my wife turned on cruise control she began getting notifications on the front panel telling her to keep her eyes on the road and drive safely. These notifications were showing up during the entire trip (300 miles) every 2-5 minutes. We contacted the dealer and have had it in the shop five times now for them to trouble shoot and try to determine the issue. We also opened a case with Hyundai corporate which they closed indicating they could not find a problem. I have spent multiple hours riding with my wife, reviewing the owners manual, and researching online in a attempt to resolve this issue. During driving test we have experienced a situation where the message “take control of the car the system is shutting down. Shortly afterwards the cruise control shuts down and the driver briefly looses control of steering and acceleration. This is a very dangerous situation at 70 mph. During my trouble shooting I feel I have narrowed down to issue to the driver assist system and the forward attention warning system on our Hyundai. Online research (reddit) indicates numerous other users are experiencing the same issue across multiple Hyundai models. It’s my opinion that this is a safety issue since the driver can momentarily loose vehicle control. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Forward facing driver assist cabin camera will shut off the cruise while you are driving if it cannot detect your eyes. This is not a safety feature but rather an extremely dangerous safety hazard!!! while you are traveling at 70+ mph and put on sunglasses and all of a sudden the car starts alarming and decelerates without warning causing the driver to become extremely distracted trying to figure out what is going on is a recipe for a major incident. There is no way to shut the camera off so you are then forced to either drive with no cruise at all so you can wear sunglasses and for long trips creates added and unnecessary driver fatigue or you forego wearing sunglasses and squinting causing unnecessary eye strain/fatigue so you can use the cruise. Please explain to me how this is a safety feature? also the warning that 'you might need to take a break' is also not a safety feature and also creates driver distraction rather than safety and should just totally be removed from the vehicle software completely. We have literally driven the car over the center line on the rumble strips without a signal and then back into our lane again the warning does not go off, we've jerked the wheel to avoid an object in the road warning does not go off, but if you happen to drive to close to the center line but don't go over it then the warning does go off. . . . . If we just left the house turned out of the driveway, the damn thing goes off. There is no making sense of when or why it goes off, it's completely random. And again, no option to turn it off. Had the dealership given complete details of these 2 specific "safety" features - I use that term exteremly loosely - sharing they could not be turned off I never, ever would have bought this vehicle. I am not alone in my complaints, I have seen hundreds of similar complaints on forums for Hyundai vehicles that have this feature. Please please issue a directive to Hyundai that they need to push a fix allowing shut off of these 2 features.

The cruise control system cuts of with message on screen stating that , system camera can’t see my face and the system DE-activates. This is especially dangerous at highway speeds. The vehicle behind me doesn’t see a brake light as my vehicle suddenly looses speed. This is from Hyundais driver attention warning (daw) function. This function cannot be DE-activated by myself or my dealership which is webb Hyundai of merrillville indiana.

Driver attention warning system constantly gives aggravating notices of "suggest take a break" with chiming sound when driving with or without sunglasses or other glasses. I cannot use cruise control. I have tried several different sunglass types with no success. After first warning, goes off every 4 minutes, either cancelling cruise control when I am using it or just causing annoying aggravation which takes my attention off the road. I cannot turn this feature off. It is so aggravating that it draws my attention from the road ahead and impacts my patience while driving. Due to eye condition, I must use sunglasses while driving in sun. Hyundai did not make this limitation clear when I was buying the vehicle, and they refuse to do anything about it now.

The driver assist program will not work if the driver is wearing sunglasses. If you are using driver assist, which includes cruise control, and are wearing sunglasses, the vehicle gives a driver attention warning. The vehicle will them cut off the cruise control causing the vehicle to rapidly drop its speed. This is incredibly dangerous at highway speeds way speeds. Hyundai and its dealerships are aware of this issue but have not offered a solution. Also you cannot disable the driver camera that cause the driver attention warning. We have also had this occur while driving at night without sunglasses. My understanding is that this issue is across all model lines.

The sensor always goes off stating my eyes aren't on the road to the point it trys to stop the vehicle in traffic. This prevents me from being able to use cruise control because the sensor is causing issues by not detecting my eyes.

The forward attention warning (faw) on the 2025 Hyundai Santa Fe calligraphy can not be deactivated. Correction, it can be turned off for normal driving. For instance, driving around the city or not using Smart cruise control. As soon as you turn on the Smart cruise control it's reactivated and can't be turned off. The faw does not work when using prescription sunglasses / non prescription sunglasses or if the sun is hitting the inside of the cabin a certain way. The faw constantly flashes warnings and beeps at you even though you are looking forward and keeping your eyes on the road. If you look far down the road you shift your eyes up some, and the system beeps and flashes warnings to keep your eyes on the road. On a recent 230 miles trip I did not wear my prescription sunglasses / non prescription sunglasses and the faw system went off at least 50 plus times and I had my eyes on the road at all times. Very distracting, I then had to take my eyes off the road to see why it was beeping and telling me to keep my eyes on the road. The faw system actually makes for a stressful and distracting drive. At this time the faw is useless. I took the vehicle to the dealer and the faw is not a system that can be turned off. Hyundai needs to allow the dealers to be able and deactivate the system.
