The contact owns a 2025 Hyundai Tucson. The contact stated that while driving approximately 40 MPH and attempting to accelerate, the lane assist suddenly steered the vehicle to the right while the road was curving to the left. The contact manually steered the vehicle to avoid a crash. The contact learned that the lane assist feature only activated while driving between 40 and 120 MPH; however, while accelerating and decelerating due to winding roads, the Lane Assist System failed to properly communicate and direct the vehicle, which the contact associated with the failure. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired. The contact stated that the vehicle had been previously reprogrammed by the manufacturer. The manufacturer was not made aware of the issue. The failure mileage was 8,500.

Previously reported issues to dealership about issues with instrument cluster going black and had it brought in for recalled software updates. Received paperwork stating completion of Campaign 302 and 304 on July 18th, 2026. While driving on the interstate on August 13, 2026 I had the cruise control, lane assist, and steering assist active. The instrument cluster went completely black and at the same time I experienced unusual steering behavior which led to me going into the next lane and hitting another vehicle.

Twice within 3 days the car drove when was in electronic park. FIRST August 1 2026 instance got in car parked in a lot. Started it (foot on brake, push start). Spent ≈ 15 min checking iPad. When car in front of me backed out of parking space, car dinged, lit up that car in front is leaving like it we were at a stop sign. Then started to move forward. I quickly braked. I may have touched the brake while sitting but never touched the shift. • SECOND instance August 3 2026 driving (MY Mode) with Smart Cruise and Lane Assist. Parked in daughter’s driveway. Foot on brake. Absolutely pushed Electronic P for park. It was my intention to leave car on for AC while dropping a bag on their porch. I did touch brake again while gathering things to get out - but did not touch shift. While I was turned sideways it drove forward into the garage door. No the foot was not on accelerator. It was on floor as I was leaning over. For reference, a few weeks ago the front camera’s sudden stop recall was done.

I have a eye condition called Strabismus/ lazy eye that I've had for most of my life. I've learned to live with it quite well. According to the American Academy of Ophthalmology, roughly 4% of the U.S. adult population has Strabismus.. My previous vehicle (Genesis G70) had the Lane Keep feature that I used all the time. Now when I drive my new 2025 Hyundai Tucson Hybred on the highway with cruise control, I can't use "Lane Keep Assist" (on the steering wheel) because within a few seconds it will give WARNING-EYES ON THE ROAD, BOTH HANDS ON THE WHEEL then go into emergency stop while I am staring straight ahead and have both hands on the wheel. - - Also, if I am driving on a Interstate highway, the Lane Keep Assist comes on automatically as soon as I engage Cruise control, I have to turn off Lane Keep or within a few seconds, the emergency shutdown begins. I have to turn it off every time I re-engage Cruise control. The first time this happened I was driving in heavy traffic on I-20 outside of [XXX]. I had to maneuver thru 2 lanes of traffic before the vehicle completely stopped. I continued on without cruise control until I arrived home. After several tests it was decided that it was my eyes. I had the Hyundai service investigate but had no fix for the issue. The Lane Keep feature was always on in my 2019 Genesis G70 which was a nice feature and now with my new Tucson, I can't use it. I'm going backward with my safety features on vehicles. There must be some way to modify this to accommodate my condition and get back to the level of vehicle safety that I once had without trading down to a older vehicle. - - Hyundai case file XXX. All updates have been completed. - - STOP/CANCEL THE IN-CAB CAMERA MANDATE UNTIL ALL THE BUGS ARE FIXED - - INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had this occur in my Hyundai and a 2026 Santa Fe lower trim model that is not hybrid. The forward attention monitor repeats that I am not looking at the road. I have a condition where my eyes have been filling with tears. I am usually able to stop it by moving my head or looking down at the camera. (which takes my eyes off the road) Many times it enters into advanced warning and twice the car started to come to a stop in lane on the interstate highway. I feel this newer attention system is too sensitive. I did not have this issue with my 2022 Hyundai Tucson. I feel the sudden braking on the interstate will lead to an accident. It happens less frequently if I turn off the cruise control, lane departure warning and lane keeping assist. I have had the vehicle at the dealer twice for recalls. I asked them to check the forward attention system and they report it is working fine. The fact that it happened in a second Hyundai and a different model leads me to think it is not just my car.

On Sunday evening [XXX] at [XXX] I was returning from Long Beach on the [XXX] home to Los Angeles, when I went under an overpass and my emergency braking system activated with an alarm and red arrow pointing to the left. There was no warning before this event. Then my lane assist stopped me from going over the line into traffic. A few minutes later the same thing happened again.

The Forward Attention Monitor (or Driver Attention Monitor/Warning...or something similarly named) that monitors the driver's eyes to insure he/she is looking forward at all times) is overly sensitive and shuts off the adaptive cruise control and lane keeping systems. While it does this, there is a beeping, and a text display on the dash that requires reading, it is probably a sentence long, further distracting the driver from looking at the road....This potentially would cause a following vehicle, or a vehicle in an adjacent lane to make a defensive maneuver, or to have to brake abruptly, as one example...basically NOT SAFE) Adjusting the steering column to a safe driving position for me (the eye sensor is located on top of the steering column) also caused this system to turn off the cruise control and lane keeping systems constantly, causing me to have to raise it to an uncomfortable driving position. Also, related to this, the HVAC controls have very dim indicator lights to let the the driver know the fan speed or status of the A/C, making it very hard for the driver to see it and make quick changes before the STUPID eye sensor (Forward Attention Monitor or Driver Attention Monitor) cuts off the other safety features. I wear NON polarized sunglasses to be able drive safely in the very bright Arizona sun, and to see the HUD which is impossible to read if wearing polarized sunglasses. I have worn sunglasses while driving for over 50 years. This 2025 Hyundai Tucson Limited Hybrid is the first car that has this very overly sensitive driver attention warning system and IF it is not adjusted quickly will cause me to sell this otherwise excellent vehicle at a great financial loss. My hope is that it can be adjusted with a software update or physical parts update, before this causes an very unfortunate vehicle accident. It makes driving this vehicle extremely unsafe. I have asked the dealer more than once about this and they say there is no current fix. thank yo

The Heads Up Display and Digital Instrument Panel suddenly go blank as if switched off resulting in no speedometer, tachometer, malfunction indicator lamps, temperature gauge, TPMS, and integrated ADAS components including lane keeping, blind spot monitoring, adaptive cruise control, 360 camera functionality. These failures are intermittent and can last for seconds or minutes while operating the vehicle. Onset seems to be related to ambient temperatures, routine ride disturbances, acceleration and deceleration activities in the normal course of vehicle operation. The issue has been a topic of discussion on several online owners forums. Owners report that Hyundai dealers have attempted to resolve this issue unsuccessfully with harness replacement, pin and connector retensioning efforts, and display replacement.
