2025 Hyundai Santa Fe Driver Assist & ADAS Problems

While I was driving on the highway, a diagnostic trouble code (DTC) related to the blind-spot safety system appeared.

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.

I am reporting a safety hazard with the Driver Monitoring/Driver Assistance system in my 2025 Hyundai Santa Fe SEL (VIN: [XXX] ). 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

1. [XXX] – I went to get into the Satna FE, the lights blinked and mirrors moved into the unlock position, but doors would not open. I had to use my husbands car since he was out of town to get to work. I came home at lunch after calling my husband and my salesperson , Paula and used the valet key and was able to unlock and get into the vehicle. I then started the Santa FE and this is when the safety warning message appeared. I felt unsafe and Paula had the Hyundai of Statesboro tow the vehicle from my home, retained it for approximately three days, and reported the issue resolved after clearing diagnostic messages and conducting a 50-mile road test. Vaden of Statesboro contacted me on October 17th stating it was ready for pickup and all the codes were cleared. I picked it up on October 18th. 2. [XXX] – The same issued with the doors not opening and had to use the valet key again, the safety warning reappeared around midday while driving, accompanied by a hard shift / drivetrain shock. The vehicle was returned to Hyundai of Statesboro at approximately 5 p.m. The dealer acknowledged the repeated issue and provided a rental vehicle for me ([XXX]), while repairs continue.

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 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.

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 Hyundai Bluelink system in my car, which interfaces with interfaces with almost all other computer-controlled systems on the car and through which software updates can be received and installed fails to work on an intermittent basis and the onboard system gives no warning when the Bluelink system has an outage or other malfunction. Large numbers of Hyundai vehicles suffered Bluelink outages beginning in early February 2025 so that system such as Collision-avoidance, emergency braking functions, and "SOS" crash notifications and owner assistance required functions cannot be relied upon. Some owners were notified by an email that their vehicles "may" have a problem and/or "might" need to have a Technical Service Bullitin done by a dealership. No distribution by model, year, or VIN and no mention of the problem as an "outstanding recall or campaign" on the MyHyundai website so that owners might be able to find out about this problem. I have tried to get answers on what the problem was, asked why the first repair campaign done on my car failed to work, why the system suddenly conncected on its own (no notice, no owner intervention to connect), and why did the system then fail again less than 40 days later. Hyundai corporate (case number [XXX]) and Hyundai Bluelink (case number [XXX]) have make promises, broken promises and fail to even provide answers and spend most of their time blaming each other.
