2024 Hyundai Santa Fe Hybrid Driver assistance Problems

Incident Description: I am reporting a recurring and dangerous safety defect involving the ADAS (Advanced Driver Assistance Systems) on my 2024 Hyundai Santa Fe Hybrid. On multiple occasions, the vehicle has exhibited uncommanded steering input. Even when the Lane Keeping Assist (LKA) system is manually disabled by the driver, the vehicle software overrides this command and re-activates the system without driver input, causing unpredictable steering behavior. System Failures & Error Codes: The vehicle intermittently displays a "Check Forward Attention Warning System" failure. Dealership diagnostics have confirmed the following historical fault codes related to module communication: •C164286, C168886, C16B902, C28B981 Related Safety Recalls: This vehicle is currently subject to Recall 265 (NHTSA 24V561000) for main floor wiring harness chafing and Recall 288 (NHTSA 25V808000) for rearview camera wiring tension. I believe the uncommanded steering and camera failures are direct results of the electrical interference or harness damage described in these active safety recalls. Safety Risk: The uncommanded steering override creates an immediate risk of a crash, especially in high-speed highway conditions where the vehicle may unexpectedly pull against the driver's intent.

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.

when accelerating at high speeds, over 70 mph, the car will sometimes appear to slip into neutral, and we are not able to accelerate at all. And then will need to coast to a stop, pull over, shut the car and restart. this has happened five times in the past year and always after one hour or more of driving at high speeds

System keeps saying that I am not watching the road, which I am. No eye glasses or sunglasses on. This causes the cruise control to suddenly disengage creating a safety hazard. SUV is up to date on software/firmware.

Have a 2024 Hyundai Santa Fe Calligraphy Hybrid with a Drivers Attention Warning problem. The warning turns on frequently when using cruise control. When the warning beeps a few times in quick succession it actually shuts down the system, reduces speed to a crawl, and turns off the engine. This only happens while using cruise control, no issue with DAW when cruise control is off. So can't use cruise control on the highway/interstate. Dealer is no help. This is obviously a safety issue when the engine turns off while driving on an interstate. Thanks

On a bright sunny day, the Hyundai Forward Attention Warning (FAW) SHUT OFF my adaptive cruise control while doing 70 mph, indicating that I was not focused on the road. I was looking straight ahead at the road the whole time. I later determined that the system was reacting to glare on my glasses (not sunglasses, no tint whatsoever, just glass). This led to a very dangerous condition because I was fighting with the car to determine what had happened (at 70 miles per hour), not focused on the road as I just had been prior. The system is checked as OFF in setup (as described in the manual) but clearly that was not the case. The driver CAN NOT shut the system like the manual says. I actually love the car, EXCEPT for that "feature". This subsystem should never have been permitted into a production vehicle and, had I known, I would never have purchased. It's that big of a problem. The system appears to be very dependent upon ambient light because I never have this issue when it's cloudy, raining, or at dawn or dusk. I have complained at 2 Hyundai dealerships here in the Chicago area, to a total of 4 Hyundai personnel, even sent a video my daughter recorded of me driving and exhibiting the issue. In 3 of the 4 cases, they replied the "system was performing as designed". That appears to be their mantra. The one service person replied that they had never heard that before. I guess they don't ever check Reddit or write down my many complaints. I think it's clear Hyundai, as a service organization does not intend to do anything about this and, perhaps worse, the company at large has no intention of doing anything as this same subsystem is part of an extensive line of their 2025 models as well.

2024 Models appear to not allow disabling the "Consider taking a break" alert even when disabling the "Driver attention warning" feature. This alert appears to go off on imperfect roads at seemingly random intervals when the car "thinks" you are driving improperly. The alert is abrupt, jarring, and unsafe in my option. I have no idea why they would release a model where you can't disable it when in previous models you easily could. It appears this is a common problem from my research online and I don't think Hyundia has made any steps to fix this.

We purchased our '24 Santa Fe hybrid on 9/18/24 new with no problems. On 10/8/24, about three weeks later, I was stopped at a stoplight after exiting the freeway. When the light turned green, I accelerated and felt a clunk, then the car would not accelerate past about 30 mph. Several warning lights came up on the dash. I could hear the engine revving, but it felt like it wouldn't go into the next gear. I thought I could make it to the dealership, which was only a few miles away. But at the next stoplight, I was stopped in a turn lane, and when I pushed on the gas nothing happened. I tried shifting back and forth from park and restarting the car, but nothing helped. The car would not accelerate at all. CHP shut down the intersection and helped me push the car to the side of the road, where I waited for a tow truck. The car was towed to Folsom Lake Hyundai, where it was purchased. Warning lights said "Check hybrid system," "Transmission control system" and "Driver assistance system." The app listed these codes under POWERTRAIN issues: DTC P198500, DTC P178400. We picked up the car from the service center on 10/11/24. They said a wire came loose from the oil pump, so they reattached it according to factory direction and it's fixed. 5 days later, on 10/16/24, the car stalled again. This time on the freeway. I entered the freeway and accelerated, then felt a similar clunk and got the same warning lights. This time, the car would not accelerate at all. I stopped on the side of the freeway and was towed to Folsom Lake Hyundai again. It took almost 2 weeks to repair, but they said the same thing happened again. The same wire came loose, causing the car to stall. Their solution was to reattach it again and wish me luck. They said maybe I drove on a bumpy road, but there's nothing else they can do but reattach it and get it out the door. I do not feel like this is an adequate repair and we are now worried that the car will stall again in the coming days.

Forward attention warning camera continues to malfunction stating camera is obscured even when not. If cruise is allowed to be engaged the camera will randomly decide it doesn’t detect your face and will hard brake to stop the car. This has happened multiple times to me, narrowly avoiding collision from behind. Hyundai refuses to address the issue because their technicians can’t duplicate the issue so they state the car is safe to drive. Camera becomes hot to the touch much like an overheating cell phone. At times camera can be covered completely and will not detect it’s obscured. This camera is a big safety hazard rather than providing any safety. Someone will die if this is not addressed-the manufacturer doesn’t seem to care to fix the issue. I’ve reported this to the dealership from the 1st week I’ve owned the car. My car has been at the dealership for this issue almost half of the time I’ve owned it. I have seen many others with the same issue in Hyundai forums-their issues have always been dismissed as not a safety issue by Hyundai as well. How can a car that will brake from a high speed or any speed for that matter be safe-just because it “thinks” you aren’t looking forward but are looking forward.

If I wear dark sunglasses, the forward collision avoidance turns off while using cruise control. If I wear lighter sunglasses, it is fine. Unfortunately, I have to wear darker sunglasses due to previous eye surgery. I am unable to utilize cruise control without compromise to my eyes because forward collision avoidance doesn’t work with darker glasses. This happens every time I test it and change sunglasses with differing shades of protection.
