2025 Hyundai Tucson

What component or system failed or malfunctioned, and is it available for inspection upon request? Automatic braking system brakes for no reason when I am not near any cars traveling at high speed or even when I am already at a complete stop or moving very slowly but not anywhere near hitting the car in front of me. This has happened multiple times since I leased this car in July 2025 and it seems to be getting worse. I had a 45 min drive home today and it happened about 7 times all for no reason. How was your safety or the safety of others put at risk? It slams on the brakes unnecessarily and the cars behind me almost rear end me. This has happened on residential roads and highways. Has the problem been reproduced or confirmed by a dealer or independent service center? I just called to take it in. They seemed to have no idea what I was talking about. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? not yet but I am taking it in asap Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NONE

The cars speedometer screen and radio screen go black and sometimes flicker on and off. This makes it impossible to see the speed. Also the car stalls sometimes when this happens in traffic. The autonomous braking applies the brakes even when there is a large distance from other cars and objects to the point where it has almost caused me to get into an accident on numerous occasions. The driver attention alert comes on and off over and over again even though I’m fully focused on driving and well aware of what is going on and this sometimes happens in a sequence where all of the warning lights illuminate on dash. Sometimes all of the warning lights display on cluster after it goes black and then car says to shift to park when display goes back on causing safety concerns for me in traffic. In addition my sunroof glass is making a loud noise like it’s going to crack.

On at least three occasions, the forward collision system incorrectly determined there was an imminent collision when a car or truck was simply coming over into my lane. The Tucscon locked the brakes, bringing the car to a full stop in the middle of high-traffic roads even while the car in front was pulling away. I was unable to give the car gas to continue driving forward. On two occasions this was on an interstate, going from almost 70 mph to stop when there was no car or obstacle in front of the car. It created a very dangerous risk of being rear-ended. The car did display the message "Collision Warning" on the instrument panel, emit an audible alarm, and shook the steering wheel.

I was on the freeway about 2 minutes and the car flashed a red warning then slammed on the brakes and I flew forward. No cruise control and no buttons hit or anything automatic. Another time,  I was merging to freeway on ramp (with 2 lanes merging and going to freeway). I was on the left right lane towards the on ramp and another car came speeding next to me on other the on ramp right lane. All of a sudden, my Tucson says emergency braking for about 1 to 3 seconds. slamps the brakes. I am not sure if the other speeding car made a sensor think I was going to merge into him,or him into me, or the sensors didn't detect the lane markings. It's my daily route to this ramp and it has not occurred in the past. These emergency braking incident has happened several times (4-5 times in a month) to me, usually during a highway drive similar to those above. I have to turn off the forward collsion to stop this happening and it comes back on everytime when the car starts from a off.

I forgot to mention that with my two accidents while slowing down for traffic or a turn, that phantom braking happens almost every day now (it happened about 7 times in 4 minutes while I was on the highway, that's not exageration) Curves on the highway with a car diagonal to you in the center lane while you're passing, weird light reflection, falling snow, dust in a construction zone, anything. I can't drive with it on as it alerts to nothing. It's very scary to drive with it on, so now I have a useless safety feature that is really more like a death trap in the right circumstances, which will come.... Someone will be doing 70 on the highway, and their Hyundai Tucson will slam it's brakes on full tilt and it will cause injury and/or death. It's only a matter of time.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at various speeds, the vehicle experienced intermittent phantom braking; the vehicle violently and suddenly slammed on the brakes with no obstructions present, causing the contact to sustain shoulder and back pain on several occasions. The contact did not seek medical assistance. The contact stated that the failure had progressively worsened. Additionally, the contact stated that the standard Smart Cruise Control (SCC) disengaged while driving. The contact stated that the failure had been intermittent, requiring the driver to manually re-engage the cruise control mode. There was no warning light illuminated. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 5,000.

I was stopped behind another car in a through-lane in the parking lot at Marshall's. I was fully stopped about 1 car length behind another stopped car. I decided to make a left turn (from my stopped position) into a perpendicular through-lane in the same parking lot. Just after I drove my entire car to the left of the parked car, my Hyundai Tucson slammed on the breaks. There were no cars coming toward me in the oncoming through-lane. There were no cars in front of me or coming toward me in the perpendicular through-lane. The FCA was OFF. Again, I don't understand why the car is appying the brakes while I'm going forward if the FCA is off.

This incident occured in The Woodlands, Texas, about a 45 min drive north of my home. I was headed south on [XXX] . I had pulled into a left turn lane at the intersection of [XXX] . After the oncoming traffic had cleared, I proceeded to make a left turn onto [XXX] . My Hyundai Tucson slammed on the brakes just as I entered the oncoming lane. The FCA was OFF. I was able to hit the gas and start moving forward again before any oncoming traffic got to this intersetion. There was no warning before the brakes were applied. Note, the FCA safety function was absolutely positively turned off. We have gotten into the habit of turning it off to avoid these unintended, unexpected sudden complete stops. Now I'm concerned the FCA system has more problems than just being overly senstive or malfunctioning causing numerous sudden braking issues.
