Automatic Emergency Braking problems of the 2025 Hyundai Tucson

Under two occasions I was driving on the highway at a safe distance from the car in front of me and my car emergency braking system triggered and went off and caused my car to stop in the middle of the highway. This caused a collision behind me. There was no reason on either occasion for the braking to bring the car to a hault.

At least 5 times now when no car was breaking extremely close to me or when I gently touched the breaks the automatic emergency breaking kicked in and slammed the car to a stop. Twice the car behind me had to swerve out of the way and hit another car causing 2 accidents without my car being involved. Once it caused me to hit my head on the steering wheel. This function is more destructive and dangerous than helpful. At no time should my car go from 70 to 0 in a second for no reason, but with this it does. Got the car in the March 2025 so 5 times in 7 months.

9/26/25. Friday late afternoon at 5pm. Driving on the southern state parkway in stop and go traffic…. The traffic opens up and we start driving to about 10 mph, with no emergency present and the car did an emergency stop on it’s own. Frightening experience…it’s amazing we didn’t get rear-ended. This is the third time this happened, but I only documented this time.

My car stopped due to the emergency braking system when a car slowed down in front of me. There was no danger of me hitting them, we were in a turning lane proceeding slowly through a green light. My car stopped and wouldn't start moving again for more time than the person behind me would have expected. This isn't the first time, but it's my first time reporting it. I'm worried that I'm going to be hit by another car at some point.

This is a very real safety concern. On multiple occasions, the automatic emergency braking (forward collision avoidance assist) feature of my 2025 Tucson hybrid was activated in a completely unnecessary situation, endangering myself and drivers following behind me. If a car in front of me brakes suddenly, or a car merges quickly into my lane, which happens all the time as everyone has experienced, my car takes it upon itself to fully slam on the brakes without warning. Each time, it was in a situation where I could have easily slowed the car down incrementally so as to not put drivers behind me at risk of rear-ending my car. This feature can be temporarily disabled in settings, but it automatically reactivates when the car is turned off then back on. This is a crash waiting to happen and it is unsafe to drive in its current state unless the feature is turned off manually every single time I start up my car. At the very least, there must be a permanent way to turn of fca.

On two different occasions (the 2nd one happened today), the automatic emergency braking system has deployed. The first time, I was in the right lane and a car passing me in the left lane pulled in front of me. I softly applied my brakes as that was all that was required. The automatic braking system then slammed on the brakes unnecessarily - causing the car behind me to almost hit me. Then, today, I was driving down the road and the car ahead was taking a right turn. Again, I softly applied the brakes. Then - the automatic braking system slammed on the brakes. No one else was near by so it there was no accident - but if there had been a car behind me, it would have likely hit me. This is twice that the automatic braking system was activated unnecessarily and much too hard - almost causing an accident.

Automatic brakes are deploying with no apparent hazard.

There are several electrical issues occurring that have put me in danger when driving. First the screen both on the windshield and the speedometer screen randomly go out completely and I have no idea how fast I am going or any other important features like how much gas my vehicle has, if the vehicle is over heating. The forward/ break feature has gone off multiple times and the vehicle has stopped in the middle of traffic and the freeway with zero warning and with several car lengths between me and the car in front of me. Almost hit from behind when this happens and has put the vehicle in park on the freeway. Steering wheel has jerked to the side when driving making the vehicle almost hit curbs and other vehicles. Has come back to my vehicle that is off and locked and the ac has been running causing the engine to be hot. All the warning lights have turned on and won't go off even after stopping and restarting the vehicle. The vehicle is currently at the dealership with them having to answer to the problem, stating Hyundai is aware of the issues but does not know how to fix it. I bought the car in April 2025 and there is just under 2800 miles on the vehicle.

Several times now the forward collision safety has activated and the car came to an abrupt stop. The car in front of me was braking and I was lightly tapping the brake pedal when out of nowhere the car started shuttering and came to a complete stop. This definitely scared me and I was relieved that the car behind me did not rear end me. I was not going fast by any means and I did not slam on the brakes as there was no need to. The forward collision is not a safety feature. This is a real problem and now I am scared of this braking design. I now deactivate this feature every time I turn the car on because there is no way to permanently dismantle this. Hyundai needs a recall to correct this.

Please see case 11675610 I have been told that this is for the same concerns I have my car is currently at the dealer for the third time to try and resolve this same issue dash will flash and go black for several seconds, when and if it comes back it will have all emergency lights on or flash no signal heads up display will also flash going blank this will be out for a longer period of time and is not always at the same time as the dash going out. When car is turned off after driving it will occasionally still show emergency lights on dash. Even after closing and reopening door, turning car back on and off safety concerns include but not limited to not seeing speedometer, safety lights and warnings.

Driving through a green light, no car in front of me, collision avoidance activated and applied full brake. If a car had been close behind me I would have been rear ended.

If someone is making a right turn in front of me and I am on the brakes already slowing down the emergency braking will engage and lock the brakes to stop it it does not seem to detect the fact the car is making a turn that will be complete before you are up to them. This has happened 4 times now and I have almost been rear ended. I can duplicate it pretty much whenever I want and capture it on my dash cam.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving and attempting to slow down, the forward collision avoidance: automatic emergency braking system activated, bringing the vehicle to a complete stop in the middle of the roadway. The vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to the dealer, who were unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 1,200.

The automatic braking has almost caused me to be rear-ended, and the enraged driver behind me leaned on his horn and flipped me off. Today, it caused a rear-end collision behind me because of the unwarranted abrupt locking of the brakes. I drove to the dealership and had them turn off this safety feature. It's very dangerous!.

No less than 6 times since leasing this vehicle the forward collision warning / automatic emergency braking has activated when it was not required as slow speed with vehicles behind me almost rear ending me. It is to the point where I no longer have confidence in using these systems and deactivate them when turning the car on. I have set the sensitivity to "late" to decrease the incidence of this happening, to no avail. I am not the only complaint about this. This vehicle is not safe to use with this feature and should be investigated and a recall issued. Vehicle is going in for service on 5/29 for this issue.

The emergency braking system slams on brakes prematurely when the car in front of me is 4 or more car lengths ahead which is causing the cars behind me to swerve to avoid rear ending me. The safety of the emergency braking is making the car more dangerous to me and other motorists.

Control screen keeps going randomly blank, for different periods of time, putting the driver at risk, because the vehicle information, including speed, lights, wipers, basically everything is displayed in this screen. Sometimes the sentence no signal shows up. I had experienced several scary situations, specially in freeways when raining, you have zero driving information. The car has been to the dealership service 4 times, with different tentatives of repair, none of which worked. The last time my car was at the dealership service for 25 days and after 2 days the problem was back, even worse. Sometimes all the lights of the control screen light up, with no reason and keep on even after the car is turned off. This is our only car and we need it, but the car is absolutely unsafe and unreliable. I refuse to leave the car for a 5th time, Hyundai has no idea what the issue is and obviously cannot fix it. The lane assist is also malfunctioning, sometimes the warning system doesn’t work properly. Twice the car emergency brakes stopped the car abruptly without a reason to do so (no risk of collision, no car or object in front ). One of those times the car behind me almost hit me, because the stop was abrupt and for no reason. I have many videos and pictures, but apparently I cannot upload the videos in this form. I have the paperwork, but Hyundai refused to refund for the vehicle. I highly recommend an investigation, Hyundai is getting away with a very serious problem and someone will get hurt as a result of these issues. Thank you for the attention.

Multiple owners of the 2025 Tucson hybrid limited awd have reported the same issue with the vehicle's "driver assistance warning" system. The system constantly beeps and, sometimes, takes control of the vehicle, slowing it down, and forcing the driver to pull over. This happened to my wife and me on our recent roundtrip from apache junction, az, to los angeles. In the middle of jam-packed, six-lane freeways with vehicles traveling at 70 mph or more the Tucson would beep-beep-beep and say "keep your eyes on the road. " but, of course, the driver's eyes were on the road. Then the system would take control and slow the car down to 30 mph or so, creating a terrifying and highly dangerous situation. And this is supposed to be a safey sytem. The system obviously was not properly tested in real-life road situations. Apparently, the height of the driver's eyes, their arm position while holding the wheel, whether they're wearing sunglasses . . . All sorts of factors seem to confuse the system and cause it to act when it should do nothing. I have turned off all the driver assistance warnings possible, but it makes no difference. And other drivers report having the same issues--unwarranted, dangerous reactions by the car that cannot be stopped by turning the driver assistance features off. Hyundai has failed in its duty to properly test its driver assistance features. The most rudimentary road testing would have revealed these issues, but Hyundai has put these vehicles on the market without the appropriate testing. Someone needs to do something about it.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving approximately 5 - 35 mph, the forward collision avoidance automatic emergency braking system activated and applied the brakes unintendedly. The contact stated that the forward collision avoidance message was displayed. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to a local dealer where the vehicle was diagnosed and the contact was informed that no fault was found with the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 5,380.

I have had two incidents where the emergency braking system applied itself when there was no reason for it to do so. Both times there was a car in the distance, over 20 feet away that was slowing, and I was slowing as well. The second time it happened, it was with great force and I was fortunate that the car behind me was able to brake in time and avoid rear ending me.

-auto start/stop "feature" since there is no way to permanently disable this feature I forgot that it was on. While stopped a stop light I was unable to move when the car behind me could not stop due to the wet roads. If the car behind me was unable to swerve in time I would have been rear-ended. By the time the engine started the car behind me was in line with my back seat. No amount of gas saving is worth being immobilized essentially in a emergency situation. - forward collision avoidance is way too sensitive, in the same trip as above a car hit their brakes approximately 6 car lengths in front of me to turn into a parking lot. The car in front of me did slam on their brakes to make the turn. As I took my foot off the gas to slow down the "safety feature" activated, applied my brakes and almost caused the car behind me to rear end me. I was going roughly 45 mph and the car behind me was roughly 2 car lengths behind me when the "safety feature" activated. The sensitivity of this system is way too high and will wind up causing more accidents then it prevents.
