2025 Hyundai Tucson Hybrid: adaptive cruise control problems

Filed Nov 2, 2026 · Airbags, Driver assistance · NY · crash · 1 injury

On Thursday night, XXX, my [XXX] son was operating the vehicle under normal highway driving conditions in [XXX]. He was driving in the left-hand passing lane with adaptive cruise control (ACC) and lane following assist (LFA) system activated. Without warning or driver input, the vehicle's adaptive ACC with LFA system malfunctioned, the car drifted to the left, overriding driver control. This unexpected system intervention caused the car to veer entirely off the left side of the highway into the grass and woods, where it struck trees and flipped over. The crash was severe enough to trigger full airbag deployment. The vehicle's integrated BlueLink system automatically activated upon impact, initiating an emergency call to dispatch an ambulance and local police to the scene. My son survived without any major physical injuries, but the vehicle is heavily destroyed. The XXX State Police - Stroudsburg has documented this under case number XXX. I have followed all servicing guidelines on this one year old car and downloaded all software updates as received. I see that this model year has a history of automated system faults, and this left hand malfunction directly caused a severe rollover accident. I have asked Hyundai to download the Event Data Recorder (EDR) data and preserve it before the vehicle is altered or dismantled. I have also informed my Geico insurance appraiser to preserve the data and coordinate with Hyundai. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

Two days after buying the car while on a trip to [XXX], while driving 70 miles per hour on an interstate using cruise control, the car quickly breaked and our speed went down to about 40. Scared us to death. We pulled off the side of the road to regroup and understand what just happened. We didn't understand and continued and stopped using cruise. We found a Hyundai dealer in [XXX] and went to ask them if they could help. It was a salesman who first quizzed us about where we brought the car, why we didn't buy from them, and pointed to the cruise control button and told us to take it back to the dealer We purchased it from. We just went on our way. Since that time, this car has braked suddendly, on it's own at least 12 or 14 times. It doesn't just brake, it stops. We have almost been hit numerous times, the seat belt has kept me from hitting the steering wheel, dash or windshield several times during this sudden breaking. I took the car in fir the recall that was supposed to fix this problem. It has not. Twice last week it decided to brake twice, once putting us in a serious position on the roadway while making a left turn. I took it back today and explained the situation. After they had it a couple of hours, they told me nothing was wrong with it. I am afraid to drive it and I know what is happening on an irregular basis.

On June 30, 2026, at approximately 8:45 AM, I was driving my 2025 Hyundai Tucson Hybrid on the freeway with cruise control set at 74 mph. While driving, the vehicle displayed a message that cruise control had been disabled. As the vehicle began slowing down, I pressed the accelerator pedal, but the gas pedal did not respond. I had to carefully move over to the right as the vehicle continued slowing, then pull over to the side of the road. Fortunately, there was a safe place available for me to pull over. After stopping, I turned off the engine, waited approximately one minute, then restarted the vehicle. After restarting, the vehicle operated normally again. I contacted Hyundai. They stated there was no specific update for this exact issue, but they did advise that there was an update for the steering cluster. I have completed that update.

I was driving using adaptive cruise control, and my entire instrument cluster went blank. Everything, I couldn't see my speed, if cruise control was on, the HUD display everything went dark then came back on in about 10-15 seconds. This was very concerning. I had no way to know if the safety systems like adaptive cruise control, forward crash section etc were still working. Lost my GPS directions, couldn't tell my speed This was extremely dangerous.This needs to be fixed asap.
