Automatic Emergency Braking Problems of Hyundai Tucson - part 1

The computer(s) responsible for many of the safety systems have faulty software. The computer vision system incorrectly assess condition of the roadway and issues warnings that obscure the instrument cluster. The computer vision system also incorrectly determines that a collision is imminent (despite no obstacles being present) and activates the braking system. Hyundai has been aware of this issue since 2022 and has previously released a software patch to correct it. However, unpatched vehicles are still being sold (and resold) by Hyundai dealerships without being fixed because Hyundai has chosen to rescind the availability of the update. Unpatched vehicles are on the road preventing drivers from properly monitoring vehicle operation as a result of the continuous warning obscuring the cluster and are jeopardizing the occupants and other road users when the vehicles spontaneously initiate panic stops for phantom obstacles. Hyundai refuses requests to provide the existing update files because a future update with an uncertain release date is planned; release of the "upcoming" update has seemingly already been delayed 8 months.

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.

During a recent accident, the driver pressed the brakes but they did not respond, almost as if they locked up. Police at the scene noted there were no skid marks on the road, suggesting the brakes never engaged. The vehicle suffered major side impact damage, including broken windows and crushed passenger-side doors, but none of the airbags deployed. This raises serious concerns about a possible brake system failure and airbag non-deployment defect. The vehicle has not yet been repaired and is available for inspection. Police have reviewed the accident, and the insurance company has also seen the vehicle, but no mechanical inspection has been completed by the manufacturer. There were no warning lights or error messages prior to the failure. The safety of the driver and passengers was put at risk because the car could not be stopped and the airbags did not deploy to provide protection.

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.

While driving I noticed my abs, traction control, aeb, and a couple of other lights came on. Upon restarting my car it was still there but the lights went away on their own after a few minutes of driving. They have been periodically turning and and off as I've driven the past couple of days. I went to the local mechanic shop who performed a diagnostic and found it to be a faulty left rear wheel speed sensor. When researching online, I've come across many people with the same make, model, and year as my car that have experienced this issue.

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.

The blind spot warning went off and locked all the brakes up. We were not able to move the vehicle and could not even pull off the road out of traffic. There is no way to disable the brakes when the computer or sensors are malfunctioning. We had to get the vehicle towed.

For the second time in a year, I was pulling into a parking space and when I applied the brake, the car accelerated, seemed to be airborne and lurched forward. Though I firmly had my foot on the break, it would not stop until it hit a brick post about three feet away. This exact same scenario happened in July of last year. Then, I hit a stand of shrubs. Someone said, your foot must have slipped off the break and hit the accelerator. I said, “I don’t think so. ” yet, I took the blame for the accident, for I could not believe it was a car malfunction, nothing close to this had happened to me since I owned the car. Everything was the same in the last crash as in the first. This time, as soon as the car accelerated, I checked, and my foot was firmly on the break. There is definitely a malfunction in the car. The black. Box should be recovered and read by someone not associated with Hyundai. I checked on Hyundai Tucson owners’ group on facebook, and my incident has been reported by others.

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.

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.

At times, this vehicle will refuse to go. You will get an alert in the dash that the emergency braking system has engaged. It may be a door is not completely shut, or sometimes it's just that I don't have my seat belt on. It seems to be inconsistent, because I often times put my seat belt on after I finish backing out, and am ready to go forward. If there is any kind of incident that requires a fast escape, this "feature" could cost somebody their life, or cause them to deal with a carjacking. The car needs to go when I tell it to go.

Issue has happened twice now, about 2 months apart. Driving at highway speeds, 60-75 mph, no other cars around, no reason for braking or stopping, the emergency brake comes up for a few seconds, abruptly slowing the car down for no reason. Very scary as the car starts to slow down from a high speed, very jolting. I've complained to Hyundai but they claim they are not aware of the issue and there are no codes the vehicle puts out so they cant investigate further without replicating the issue, but its random and you don't know when its happening. I've looked online and it appears there are quite a bit of 2023/2024 Tucson's that are having the exact same issue I am.

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.

The car slammed on it's brakes on the off ramp even though I had plenty of time to slow down. It came to a full stop before it let me accelerate again and I almost got rear ended.

All of a sudden my 2024 Tucson gages indicated emergency braking for about 1 to 3 seconds and the front end went down as though I was stopping (scared me ). I was so happy no one was behind me. No one really behind me or to my left. Only one car to the right of me in another lane. Also, had to replace air bag at 6176 miles.

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.

Forward collision emergency braking. Have had this happen on 5 different occasions. Very dangerous. The vehicle without warning slams on the emergency brakes and issues a warning. Took into dealer and they could find no error codes and did nothing. First time this happened I thought maybe a bag or something flew up and obscured the forward facing sensors. Pulled over and checked nothing. Then 3 times it happened within 5 minutes. Pulled over and sensors looked fine no dirt or anything on the sensors. Can not drive car with this and so have been disabling the system except for a warning tone. Today it activated it again. Usually when I approach something the sensors turn yellow and then red when getting real close to an object. But today when it activated when not close to anything and driving down the road all the forward sensors activated with the warning but it was gray. (not yellow or red) since I had it on warning only the brakes did not activate. This is very dangerous and unless you disable the automatic emergency braking could lead someone to plow into the backend of the SUV and it evidentially does not cause error codes. Yes,someone can contact me concerning this. This has happened multiple times. Intermittently.

While driving 70mph on the freeway, the car’s emergency braking assistance activated twice for no apparent reason. This is very dangerous at such high speeds and could result in a serious accident if cars are following close behind. This car has not been inspected for this issue. A google search of this issue revealed many similar complaints that have not been addressed or taken seriously. A possible related warning message about “blocked forward safety” has appeared a few times in the last week.

-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.

While driving approximately 75 mph in the passing lane on highway, the vehicle suddenly automatically brake. Pulled back into the right lane and didn't really understand what happened. Next time I pulled out to pass and had a car on my right hand side it did the same thing. Pulled back into right hand lane and stayed there for quite some time. I then turned off the all around sensor @ and it didnt do it again but as I got closer to home the warning light came on and a message popped up. It now has the triangle caution sign on and the picture of car icon in amber. I had driven the car from my home for about 50 miles and parked car for two hours, the drove back toward home for about 20 miles when the event happened. It was dangerous and makes not want to use any of the "assist system's" going forward. I plan to wash the car today to see if the lights will go off- if they don't then I shall call dealer on Monday. This occurred on Saturday. Ill be washing car today (Sunday). If I had anyone driving closely behind me, I for sure would have been rear ended.

My car automatically braked in the middle of an intersection and caused my vehicle to be rear-ended. This was the third time automatic braking engaged when it should not have been. In the most recent incident on 30jan2025 I was injured and had to have medical attention. I googled automatic braking and there were many reports of automatic braking being deployed when it should not have been.

While driving my 2023 Hyundai Tucson phev with limited trim the emergency braking function activated for no reason at all. This has happened 5 times during the last 9 months and each time it was about the same conditions. Road was dry my speed was from 55 to 75 mph it was during daytime hours and no cars were in front of me or on either side of me. 3 of the times there was a car behind me that had to check up I guess because my brake lights came on. I reported the problem to the dealer and was told no other owner has ever reported than problem. Instead of preventing an accident the activation of the emergency braking system in this situation could have caused an accident with the cars around me reacting to my sudden braking at high-speed resulting in a chain reaction.

I was driving on a highway at 75 mph, on a clear day, with perfect visibility and driving conditions and my automatic emergency braking engaged. I was on cruise control with no one in front of me for approximately half a mile. There were cars behind me, so I had to swerve into another lane to avoid being rear ended. There was a sequence of beeps. If there were warning lights or messages, I was too busy dodging to see them. There may have been a squiggly line that came up, but I am unsure.

A week ago, I was driving my 2022 Tucson hybrid limited on the highway on my way to work around 7:50 a. M. It was a bright day, good weather. I was in the center lane when my car suddenly braked hard and came to a stop on the highway! my foot was still on the gas pedal, but the automatic emergency braking light was on. I panicked because I had no control over what the car was doing. Thankfully, I was not rear-ended and didn't cause an accident. I put on my hazard lights, shifted into park on the highway's center lane, then back into drive and it seemed fine. There was not really any traffic in front of me that I remember, but there were some cars on either side and behind me that had to swerve around me. I don't trust this car anymore. It is going to get me or someone else killed. I took it to the dealer 2 days ago and the initial inspection didn't show any problems or error codes. They told me I could have it back since there didn't seem to be a problem or they could give me a loaner car and keep testing my car. I have a loaner. I hope they find something wrong with the car, otherwise, I am afraid of my car getting me or someone else killed. I am especially scared after reading about all the others here who have had this same issue.

While driving in light traffic, speed at 45 mph, my Tucson alerted me with a beep, steering wheel vibrated and a red alert on the dash was present for about 3 seconds then the speed automatically slows down to 15 mph all on its own while my foot is still on the accelerator. This has occurred at a minimum 6 times. I purchased this vehicle brand new and driving it off the lot it had 22 miles on it. I've taken it to a Hyundai dealership, and they can't figure out what it wrong with it. I feel very unsafe and unhappy now of this major safety concern. This has high probability of getting rear ended. I see that this has been occurring with various years of Hyundai and am wondering why there has not been a recall on this issue. I owned a Hyundai prior to this 2024 (tucson 2011) and it was wonderful. This is highly concerning for me, and I am not confidant driving this vehicle and will more than likely trade it in for another vehicle. Can someone please research this issue with the automatic emergency brake system. This can autonomously go off whether you are in traffic, highway, street or completely zero vehicles or pedestrians around.

Automatic emergency braking deployed without any external threat. I was driving 55 mph on the freeway and the automatic emergency braking engaged. The dash lights flashes, there was an audible alarm and the car braked. There was no danger in front of the vehicle and this action put me at risk of being hit from the rear by the car behind me. My safety was put at risk as my acceleration was greatly diminished compared to the traffic around me. There was no warning of the problem prior to the failure. It has not been confirmed by the dealer.
