Hyundai Santa Fe Hybrid adaptive cruise problems

Filed Oct 22, 2026 · Driver assistance · PA

Traveling the PA Turnpike with the cruise control on and traveling 73 mph. I was in the far left lane and just passed a slower car. There was nothing in front of me in the far left lane or the lane next for at least a half a mile. After just passing the slower car the forward collision avoidance came on and tried to stop the car. I put my foot on the brake as an instinctive action which I believe disengaged the Forward Collision Avoidance system. The dash board lit up saying it was the Forward Collision system. If there was another car/truck following me closely they would have hit our car and at that speed I am sure I would not be here writing this. Calling today the dealer to have this checked out. No one else has inspected or checked this problem yet.

This is the SECOND occurrence in the past two weeks. I was traveling on a HEAVILY trafficked 10 lane divided interstate, doing the speed limit on cruise control when the vehicle suddenly and inexplicably lost power. It went into "limp mode" (will not go over 30 mph). Thankfully i was able to negotiate to the shoulder but the maneuver was EXTREMLY dangerous as the rest of traffic was moving between 60 and 80 mph. It was harrowing and extremely frightening. Warning lights that were displayed- First, a "Check hybrid system" message appears. Accompanied by SEVERAL other warning lights. Eventually, a "stop vehicle and check power supply" message appeared and would not even move in "limp mode". This appears to be either a bent connection plug or fuel injector issue. The first time this happened ([XXX]) it was towed to Southern States in Raleigh, NC (I purchased it from Johnson in Apex) where they concluded nothing was wrong. They claimed no codes were available other than some low battery codes. This was a lie. The vehicle app showed two codes-POC7300 and P193700. They did nothing but recharge the battery by running the engine. I feel this dealership put me in danger by putting me back on the road without a proper diagnostic. A simple Google search shows that this is a problem with other vehicles of this make and model. I was told it wasn't their job to Google problems. It's only a matter of time before this serious defect kills someone with less luck and driving skill. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Occasionally the cruise control will go off. Sometimes it will reset itself & other times, the driver has to initiate. I reported to the Hyundai Manuf. last yr. & also had 2 separate dealers take a look & problem has not been resolved.

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.

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.

The cruise control was set at 75 mph and we were driving down the interstate when the engine suddenly lost power and shut off. This happened with no warning and no warning lights activated. Several days later, we were driving down the interstate with the cruise control set at 72 when the engine again lost power and shut off. We were able to get the car to move again both times by shutting off the cruise control. No warning or warning lights activated either time the engine lost power. We were very lucky not to get hit by oncoming traffic both times the engine shut itself down.

I was driving on the 202 at 80 MPH in the HOV lane and was engaging the cruise control. Pretty soon the car started beeping and it was saying something to the affect that I wasn't in control of the car. I started yelling and gently swerving not understanding what was going on to make it think I was indeed driving. It wouldnt' stop. I was in high traffic bumper to bumper than the dashboard started blinking and throwing a fit then it said it was going to shutdown the car!!! I tapped the breaks and then it stopped. Then a few months later same thing. Engage the cruise driving on the 202 roughly the same time of day- high traffic, it started again this time I started cussing, waiving my hands all around trying to get the car to know I was driving. It started saying it was going in to emergency shut down. I accidently hit my prescription glasses off my face in a panic and then it all stopped. I went home and googled what happened not understanding what this Forward system does or what it looks at. I had no idea the car was looking for my eyes. If I had been told this we would not have purchased the car in the first place. I have to wear prescription transition lens because I have chronic migraine syndrome. Light is one of many causes of my headaches and I live in the sunniest place on earth. So, I can't have this car. It is dangerous safety defect because t is issuing a false eye not detected alerts while wearing my glasses eventually leading to shutting the vehicle off. This creates a severe hazard, as the system will deactivate cruise control or initiate a sudden breaking at high speeds causing a collision or even death. I can't even drive my own car.

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.

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.
