2026 Hyundai Santa Fe Hybrid

The Driver Attention sensor cannot be turned off. In a recent trip it engaged a dozen times over a one hour ride, a ride I was completely fully alert for. I find the warning itself to be a safety issue and very distracting while I'm trying to drive and follow a map to have it constantly be going off. A simple software update to provide ability to turn it off would resolve this and there are hundreds of similar complaints about this that I can find in message boards. Unacceptable.

"take a coffee break" warning goes on an inappropriate amount of time. When I drive straight down the highway it alarms. However, if i cross the white lines it does not alarm. Also when this alarm turns on all other sounds systems in the car go silent including the GPS/Apple Carplay. I have missed exits and turns due to this alarm going off. There is no way to turn it off or make it less sensitive. I consider this alarm to be unsafe and annoying.

Please keep in mind that I am not a mechanic and only a consumer so my specific knowledge of vehicle systems is limited. The vehicle is available for inspection upon request. On July 9, 2026 while reversing out of my sloped driveway my Hyundai Santa Fe Calligraphy Hybrid conducted a sudden, uncommanded emergency brake stop without warning or cause. This occurred one week prior as well on an unknown date. The system appears to misinterpret the angle of the incline and encroaching tall vegetation as a solid obstacle. This uncommanded malfunction caused a rapid deceleration that directly caused and exacerbated my post concussive syndrome, cervical strain, occipital neuralgia, hyperacusis, and noxacusis, requiring treatment at an Urgent Care clinic on Saturday July 11; the unresolved defect poses an immediate crash and bodily injury hazard. I am going to also need pain management therapies. I attended an appointment at the McGrath Hyundai of Cedar Rapids on Monday July 13 for assistance with this among other things that were occurring with my vehicle. I also have been reported experiencing an interconnected systemic electrical failure, including dashboard cluster loading lag, a complete failure of the Head-Up Display (HUD) to register speed limits, and intermittent green color distortion on the blind-spot turn signal camera display, which shares the camera network used by the reversing safety systems. These issues began around the same time as the sudden emergency braking. I am unsure if they are related however it would make sense. They did not fully conduct the tests necessary to locate the problem as a simple diagnostic scan will not do that. The sensor calibration might be off among other causes. The dealership did not look at the EDR to determine the history of this emergency stop occurring. I am currently working with a Hyundai Corporate investigator whom their team agreed for my vehicle to be inspected by a field engineer. I am currently awaiting their call.

Driving through a green light going 45 mph and my car had an episode of “phantom braking” and decided to automatically brake out of NO WHERE. Slinging me forward and scaring me. No warning signs or chimes came on before, during or after the incident. It made no sense. I’m scared to drive this car with my baby in it now in the fear of going the speed limit or driving on the freeway with it randomly auto braking out of no where and making me crash with my child in the car or something worse happening with my baby inside the vehicle. I’m very displeased and worried.

Component Failure I was driving on [XXX] in [XXX] at 70 miles per hour. My red oil indicator light came on, and within seconds the vehicle suffered a catastrophic power loss. I had zero control of the propulsion. I was in the right lane and managed to steer to the shoulder. I contacted Hyundai Roadside assistance/Hyundai care. They sent a wrecker in about an 45-1 hour as I sat on the side of the highway. I was then put into a wrecker and my car was loaded on a flatbed truck and we then took a 45 minute drive to [XXX] to Weisner Hyundai where the vehicle was left for diagnostic testing. Safety My safety was undeniably at risk due to going the speed limit to zero in seconds. It put me in harms was due to other drivers on the road not expecting a car to stop at those speeds, unable to react in time without causing a collision which could have resulted in significant bodily injury or death for myself, my passenger and possible many others on the road that were around me. I was afraid, not sure what had happened, very distraught and traumatized. I fear for my safety in this vehicle. Service Center The car was taken to Weisner Hyundai at this time they have been unable to replicate or discover any code. They have seen the oil light come on. They have had my vehicle since XXX until today XXX when they were going to send it to [XXX] Hyundai where I purchased the vehicle. Inspections I am not sure about who all has looked at it within the dealership. Warnings The only warning I had was a red oil lamp that appeared on the dash seconds before the catastrophic loss of power. Special Note, I just found out that my vehicle originally had repairs done as it came from transport to the engine/oil components which were not disclosed to me by the dealership prior to me purchasing the vehicle "new" at full price. The dealership had knowledge that the vehicle already had issues that cause the malfunction and sold it knowing the dangers.

The Driver Attention Warning system activates a "coffee break" alert repeatedly after approximately two hours of continuous driving, regardless of actual driver attentiveness. There is no way to permanently dismiss or disable this alert. When attempting to cover the cabin camera to stop the alerts, the vehicle triggers a separate "Limited Assistance" warning that is equally intrusive. There is no scenario where the driver is free from one alert or the other during extended drives. This has created dangerous situations. I drive frequently through mountain roads with sharp curves, steep grades, and limited shoulders. On multiple occasions these alerts have diverted my attention from the road at critical moments and I have nearly been involved in accidents as a direct result. A system designed for safety is actively making driving less safe by forcing interaction with dashboard warnings instead of focusing on the road. The component is available for inspection. The system is functioning as programmed, which is the core problem. It is not a mechanical failure but a design issue that creates a real safety hazard for anyone driving longer than two hours. The problem has not been taken to a dealer as it appears to be functioning as Hyundai intended. The vehicle has not been inspected by the manufacturer, police, or insurance representatives for this issue. No prior warning lamps or symptoms preceded this. Alerts began as soon as I started making drives exceeding two hours. The problem is fully reproducible on any drive of that length.

1.Fuel did not activate on this hybrid while in stop and go traffic when apparently the battery died. There was plenty of gas in this brand new car. The entire car died, gas pedal inactive, on the freeway just when traffic opened up with red car/exclamation point indicator on dash. After power cycle car Its message said something like “pull over and charge car in park”. We were close to shoulder so were able to do as instructed. 2. Car died suddenly in freeway traffic w 4 passengers inside. Could have been rear ended. There was no information in manual, on line or through BlueLink app on the battery function, this particular message or the problem. Or criteria that causes car to fail without switching to fuel. 3. Days later when I could get an appointment, The Escondido Dealer did diagnostics, visual and test drive and found nothing. Dealer had no means to look back at history to ID fault codes at time of event. I had exact time/miles. They did not check battery as the diagnostics were clean. Complaint made w Hyundai consumer affairs. [XXX]. Case XXX. They could not tell me criteria or specifications for message to pull over. They could not direct me to battery or “switch to fuel” criteria. They are working on case. I fear a software bug or engineering issue. A non plug in hybrid should function on gas if battery cannot work. 4. No insurance claim or police notified 5. There were NO warnings prior to the car dying. The Car died w red exclamation in red car indicating service right away. We put on flashers & We power cycled and words came up on dash stating something like “pull over and charge car in park” Engine temp was good as we watched it. We pulled over and car was functional within 10 min. We drove home without any further issues. Car had 1345 miles total at incident. Brand new car. Less than 2 mos old and we started trip w ~297miles. I was unable to get photo of warnings as they happened. Just after while sitting in traffic.

Depending on the angle of the vehicle and the sun, around the heads up display the sun will reflect off of the plastic causing a thick bar of light on the windshield. This can make it very hard to see while driving and is right in the line of sight. Brought the car to the dealership and was able to reproduce it under the right conditions with another vehicle of the exact same model. In attached photos, it shows the glare in 3 different spots. It's all depending on the angle of the sun and vehicle but it's all across the heads up display.

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.
