2025 Hyundai Santa Fe Hybrid: adaptive cruise control problems

Filed Aug 28, 2026 · Acceleration, Engine · WV

When traveling home from work 8/27/26, my cruise control shut off and my car immediately went into “limp” mode. This almost caused me to get into an accident with a tractor trailer, in which, I may not have survived. Immediately pulled over and tried to find out what had caused this and how to get it fixed. Nothing worked to get it out of “limp” mode. There were no warning lights or messages, except LV3. Which was a completely different issue. This issue I was able to correct. Tried fixing the “limp” mode issue by doing as told by Google AI, turn car off, lock door with key fob, waiting 10-15 minutes for computer to reset. NOTHING. Also tried checking to see if there was a battery dump, in which this case would have been the fuel system not communicating with the hybrid battery system, NOTHING. I do have an appt with the dealership on 9/2/26 to have this looked at and inspected. I have not tried to start and or drive the car again, since. Do not want to be blamed by the dealership or manufacturer, that I did something wrong or caused more issues.

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

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.

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.

Hyundai disabling critical vehicle safety systems if people wear sunglasses. I brought MY2025 hyundai santafe hybrid, this has driver attention monitoring system. Since the day i brought this vehicle i have been getting issues related to driver attention warning system. This error is being caused for no reason, this comes on when vehicle comes on and stays on (sometimes for days sometimes for weeks and sometimes for hours). HYundai says this issue is because i have a dash cam in car, error wont go away even when dash cam is removed. Recently hyundai engineers said its because you may be wearing sunglasses. What? Wearing sunglasses will disable AEB and cruise control !!!OMG. I removed sunglasses and tried still wont work. Hyundai sent me list of things not to do, including not to laugh, not to shorten your eyes and not to wink. this is a major safety concern, not allowing drivers to wear sunglass which will disable safety critical systems.

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 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.

I was on a semi residential-commercial street that turns on to a freeway entrance. I was turning right and unavoidably entered the freeway when the sudden loss of power occurred. The car slowed down to about 20 mph and pressing on the gas medal didn't yield any more power. I immediately pulled over to the emergency lane upon entering freeway to let fast moving vehicles pass me on the left side. I turned off the vehicle and turned it back on. It seemed to turn on as normal so I proceeded to drive home slowly, staying on the slow right lane of the freeway driving under the speed limit until I took my exit to get to my home. All seemed ok until I turned onto residential street near my home. Again the car slowed down suddenly to 20mph and giving it more gas did not make a difference. The time difference between the first and second (recorded) incident was 25 minutes apart, having driven the vehicle only 140 total miles. The dashboard flashed a 20mph speed limit even though I never set those parameters, didn't set cruise control, and I didn't have auto stop or hold buttons engaged. The car simply slowed down to a 20mph speed limit without my input to the vehicle settings.

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.

This is a concern about the Driver Assistance Warning Consider Taking a Break 5 bell warning system. While we understand and appreciate the many safety features on new cars, we feel this feature is a safety distraction and hazard. We have turned this feature off in the Driver Assistance Warning section and we have turned off the bell. Despite this, this warning with its 5 loud distinct bells sounds very frequently and often automatically disengages our cruise control while we are driving on the highway. In a recent vacation road trip of over 3,000 miles, the enjoyment of our trip and our new car was greatly compromised. During that time we tried to discern what actions we were doing to cause it to go off. It would go off when looking at the gauges so we would try to look quick and then eyes back on the road. We tried driving without sunglasses (which is a hazard itself), making sure our hands were at the 11 and 2 position, looking straight ahead. Nothing seemed to make a difference, it would go off randomly and often. Careful and safe driving requires a driver to scan the rear view and side mirrors, the gauges, be aware of other drivers proximity to your vehicle and avoid staring only straight ahead. I am aware that there may be consideration of a mandate for all cars with this feature in the future, however, as of the time of purchase of this vehicle, this law did not exist and as such, we should have the right to choose to use this feature or not. We have contacted Hyundai Corporate and visited 3 dealers, none of whom would or could help except to tell us many others have voiced the same complaint. In our opinion this system as it currently operates is more of a hazard than a safety feature. We are seeking a software update or whatever means necessary to turn this feature off completely even when using cruise control.
