Automatic Emergency Braking problems of the 2025 Hyundai Tucson - part 1

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 turning right from [xxx] onto [xxx] . It was raining lightly, the car initiated emergency braking and no one was in front of me. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Subject: 2025 Hyundai Tucson - persistent phantom braking issue I am reporting a severe safety defect regarding the forward collision-avoidance assist (fca) system on my 2025 Hyundai Tucson. Since purchasing the vehicle, I have experienced five separate "phantom braking" incidents where the automatic emergency braking (aeb) engaged abruptly without any obstacles in the path. In the most recent incident, the vehicle suddenly braked from 30 mph to 20 mph] while driving on a highway. There were no cars or objects in front of me. This unpredictable behavior is extremely dangerous as it almost caused a rear-end collision with trailing vehicles. I believe this is a systemic software or sensor defect that misinterprets shadows or road signs as hazards. I request a formal investigation into this safety risk.

I was driving on the highway in heavy traffic going about 65 mph. An unusual symbol appeared on the dash in red that I don't know what it was or what it meant but I thought it must be something serious. Then a warning came up saying for me to take a break. Then a different warning came up saying that I should take control of the car immediately, it was about to brake. The car immediately began to brake. Fortunately I was in the right hand lane of the three-lane highway and I was able to pull into the breakdown lane. I can't even imagine what would have happened if I was in the middle or far left lane. I was not unobservant and both of my hands were on the steering wheel when this happened. Once the vehicle stopped, the symbol on the dash disappeared and the brakes released. I was able to resume driving. Although there was no accident, injury or fire, and no police report needed, this does not discount the seriousness of this event. This could have been life-threatening if I had been in a different lane or had panicked, causing a multi car pileup in the heavy traffic. Serious enough that I feel the need to get rid of this car.

The automatic emergency braking and forward collision warning systems activated while making a left turn after stopping for a red traffic light and locked the brakes of the vehicle in the middle of the intersection with no other car in front of me. Dash alerted that a collision was going to occur. This was the second time. The first time it happened the dealer said it can happen if there is a bug or dirt on the sensor in the bumper or dirty windshield by the camera, they even said it can happen with glare from the sun or light glare.

Over the past four days, my vehicle has repeatedly applied braking unexpectedly without a valid obstacle or need to brake. This has occurred multiple times under normal driving conditions, including: twice on the freeway in stop-and-go traffic with vehicles at a safe distance ahead multiple times on regular city streets with vehicles ahead at approximately 15–20 feet once while turning into my driveway as my garage door was opening in one instance on the freeway, a vehicle behind me nearly collided due to the sudden unexpected braking. The forward collision-avoidance assist (automatic emergency braking) system is set to “late,” yet the vehicle still applies braking unnecessarily. This behavior did not occur previously and has started happening repeatedly within the past four days. This creates a significant safety risk, particularly in traffic where unexpected braking can cause rear-end collisions. The vehicle has approximately 1050 miles and has not been modified. The issue is currently being evaluated by a Hyundai dealership and has been reported to Hyundai motor America under an open case.

Hello, in my 2025 tuscan hybrid, the vehicle all of a sudden came to a near complete stop driving down the highway at lower speeds due to vehicles in front of me slowing down before a tunnel. While it was apparent I had to slow down, there was no immediate danger to me potentially crashing into the car in front of me which is why I am concerned the car is over reacting to my environment whilst driving.

Subject: safety concern – excessive automatic braking (2025 Hyundai Tucson) I am reporting a safety concern regarding the automatic braking system (forward collision-avoidance assist and parking collision-avoidance assist) in my 2025 Hyundai Tucson. The vehicle frequently applies sudden and aggressive braking in situations where there is no immediate collision risk. This occurs during normal driving and low-speed parking scenarios, including when passing nearby objects, backing out of parking spaces, or maneuvering in tight areas. The braking is abrupt enough to create a potential safety hazard, including: - risk of being rear-ended due to unexpected deceleration - disruption of normal traffic flow - reduced driver confidence and control this behavior appears overly sensitive and does not align with actual collision risk in many cases. I have attempted to adjust the system settings (including warning timing), but the issue persists. Additionally, the system resets upon restarting the vehicle, preventing a consistent mitigation of the problem. I am requesting: - a review of this system behavior as a potential safety defect - a software update or calibration option to reduce braking aggressiveness - the ability to permanently adjust or disable this feature please advise on next steps and whether this issue is known or under review. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When driving in daylight at about 5 pm in light traffic at speeds of about 20 mph the car suddenly had a dead stop. My grandsons, ages [xxx] and [xxx] were in the back seat with seat belts but their and my drinks went flying. There was no potential collision that precipitated this and luckily the car behind was not close enough for a rear end collision. This has happened 2 or 3 times previously and I think this "safety feature" which cannot be turned off is a safety hazard. I also had a disturbing experience when I left a lane briefly to give a bicycle rider more space. The car suddenly tried to pull me back into the lane and I had to fight the wheel to keep it where I wanted the car to be. I was able to disable this feature. The car has only 7k miles and is almost a year old. I am a good driver and am concerned that I will get into an accident due to unwanted safety features! thank you.

Automatic braking engages when there is no actual hazard present and brings vehicle to a full stop. This causes a serious whiplash hazard to me and my passengers as our heads are thrown forward unnecessarily. It also significantly increases the risk of being rear ended by the vehicle behind me. This has happened on several occasions. Today it occurred because the car hit a small bump in the road while doing less than 10 mph. Google search confirms that this is a widespread and well-known defect and that Hyundai has not been willing to release a software upgrade that allows owners to turn-off they automatic braking feature from the dashboard control panel. Immediate action by NHTSA is required before somebody gets seriously injured or killed by this defect.

On at least three occasions, the emergency braking system has engaged when there was no risk of a collision. The vehicle ahead was moving forward and was a safe distance ahead. This has occurred even when the forward collision system is set to "late. " when the emergency braking system engaged, it stopped the vehicle with such force that it threw items in the back seat forward into the foot well and was very jarring for me, the driver. This has made me anxious when driving the vehicle and is very frustrating.

On March 16, 2026, my wife was driving our 2025 Hyundai Tucson westbound on immokalee rd in naples, FL. She was traveling at a speed of 35mph, with no vehicles in front of her, but the emergency braking system engaged without warning and caused our car to come to a screeching stop. Several cars behind my wife's car had to avoid slamming into to our car. There are no bridges, overhanging tree limbs or other structures over the roadway. The weather was clear skies and sunny, and the time of day was noon. After this incident, we contacted the dealership from which we bought the car (11/15/25) here in naples. We brough the car in for diagnosis but have not heard back from them. While there, my wife was approached by a dealership salesperson who overheard our story, and she implored my wife to "please report this incident. . . This phantom braking issue is a big deal. . . " our salesperson did not admit to having heard of such issues, but he offered to buy the car back from us. We will wait to see what their formal evaluation produces and make a decision at that time. This could have been a deadly accident if the cars behind my wife had not avoided running into her.

After taking a left turn my car suddenly just stopped abruptly. There was a car behind me who just missed running into me.

I was driving inside a parking garage, making a right hand turn at a very slow speed (5 mph?), when my Hyundai Tucson hybrid slammed on the breaks while in a right hand turn. There was a wall directly in front of me, perpendicular to the direction I was heading before I started to make my right hand turn. The wall was at least 15ft away. I was never at risk of hitting the wall. The breaks were applied after I was into the right hand turn. Most unusual, as I had the fca (forward collision avoidance) system turned off and I confirmed this by observing the symbol on my dashboard that indicated the fca was off as soon as the breaks were applied. I don't understand how the car applied emergency braking going forward when the fca was off.

The brake assist feature engaged when a second car cut a corner in front of me in peoria az. The brakes engaged, and while waiting for the auto brake to release, a third care came up very fast behind me. I hit the gas in fear of being rear-ended. Apparently, in fear I simultaneously pulled on the steering column and the steering column pulled out beyond its normal range. The telescoping adjustment feature no longer works. The steering wheel is locked in a downward and elongated position. I took it to the local az Hyundai dealer for warranty repair and they said it was due to the kirkland Hyundai dealerships failure to install a pin that locks the steering column in place after installing a lo-jack system. The column is not covered by warranty. There were no warning signs except the dangerous auto braking system, that caused a series of failures in the vehicle. This is the 4th time this braking system has almost caused a rear-end crash. The az larry miller Hyundai dealership suggested I contact the kirkland Hyundai dealership in wa for damages. Damages to replace the steering column and replace the missing pin lock are nearly $3000. 00 there are no pictures as the steering column has been reassembled but is bent and needs to be replaced.

The contact owns a 2025 Hyundai Tucson. The contact stated that the vehicle was stopped at a traffic light, while attempting to accelerate, the brakes engaged unexpectedly. On another occasion, while driving approximately 60 mph, the brakes unexpectedly engaged without driver input and failed to properly respond for approximately 5 to 10 seconds. There was no warning light illuminated. The vehicle resumed normal operation afterwards. The forward collision avoidance early detection sensor indicator was illuminated. The vehicle was towed to the dealer; however, the technician was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 14,946.

I was driving straight in the left most lane on an expressway, about to make a left turn on a green left turn arrow. The vehicle in front of me was making a u-turn. My Hyundai Tucson abruptly braked quite hard. I'm not sure what caused it but I'm guessing the vehicle making u-turn slowed down a bit before the u-turn and might have triggered a forward collision avoidance braking but I didn't feel like there was a need. This caused the vehicle right behind me to also abruptly brake and if they hadn't, they might have rear-ended my car. After making the left turn, the vehicle behind me angrily overtook me because they likely didn't know it was the car's system which did this.

On two occasions, the automatic emergency braking system engaged potentially causing an accident. The first occurred at an intersection where I was attempting to turn left from a stop. The system would not allow me to proceed until the bus attempting an opposite left turn left the intersection. The weather was clear and sunny. The second occurred while on a freeway onramp. There were no vehicles in front or to my side. The aeb detected a phantom threat and immediately braked to a stop. The car behind me was barely able to avoid rear ending my vehicle. My passenger was a witness to this jarring event. The weather was clear and sunny. Both incidents occurred with an odometer reading of <3500 miles. My local Hyundai dealer has attempted to recreate the phantom breaking, but were not able to recreate the circumstances and therefore not know what system required repair/replacement. The case #42211163 was assigned. Given the uncertainty of when the system will inadvertently break and the inability to permanently turn off aeb on this vehicle, I am very concerned about driving the vehicle.

The forward collision avoidance system in this generation of Hyundai Tucsons is dangerously flawed. We previously had a 2020 and no issues, but this one slams the brakes at the drop of a hat and has nearly caused several accidents as there is no good reason for the intervention (ample space to leading vehicle) and it brakes so hard that cars behind typically need to veer to avoid rear end collision. This is not a one-off event or linked to particular driver/driving style - both adult owners of this vehicle have experienced this on multiple unrelated occasions. All sensitivity setting have been set to minimum and the only way to drive with peace of mind is to completely disable the system - but here is where the next massive design flaw the system automatically reenables at each re-ignition; there is not permanent override, which is extremely dangerous. It is not practical to manually disable the system on each drive because you need to navigate multiple system menus to adjust the setting. Google and user forums confirm this collision avoidance system is a widely experienced and complained about safety issue for Hyundai and it should be investigated. People will likely get killed due to this “safety feature”. Ideally Hyundai should push a recalibration for those who want this feature and enable a permanent override option in the system settings for those who don’t.

Hard braking first occurred on a major highway with no prior notice that this would happen in close call accidents. The cars traffic had to veer away from me in order to avoid hitting me. Another highway (95) incident was a 18 wheel semi that had to move to the shoulder and could have easily totaled my car and me. I then researched this and found I could delay the action be setting the forward collision-avoidance assist mode to "late". This helped in giving notice for some time, however the hard braking occurred again on a regular two lane small highway as I switched lanes, saw a car stopping suddenly and the brakes locked up. (this is the latest incident as dated below). There was no "late" warning, the brakes just locked up. Being in fear of my and my families life I did further research and found that I could disable "brake assist" and only get warnings - which is what should be the default - but, this must be done each time I start the car. If my wife drives and forgets to do this each time I now fear for her life!!! this is not a simple matter. It is unconscionable and horrible this type of control over basic transportation is allowed to exist. This must be addressed and corrected! I'm all in on helping make meaningful change to this issue.

Had just turned out onto a major road and started to accelerate. At approximately 30 mph forward collision system alerted and applied automatic emergency brakes even though the next car was several car lengths ahead of me and there was absolutely no risk of forward collision. The vehicle immediately behind me had to slam on their brakes to avoid rear ending me. Thankfully, this was coming out of school zone so their speed was not high. At regular street speeds this malfunction would have likely resulted in a crash with injury. During the time that the automatic brake system was activated I could not override. I used gas pedal but car would not accelerate until the system stopped, perhaps 2-3 seconds later. Car was purchased used within last month and had an inspection by seller then, but I am not aware of any inspection by manufacturer/ dealer.

The forward collision avoidance engaged when it was unnecessary and nearly caused me to be rear ended. It doesn't slow you down, it brings your vehicle to a complete stop and leaves you stuck unable to move for a few seconds. . . Just long enough for the person behind you to read end you. This is incredibly dangerous. I would speculate that this feature will result in many rear end wrecks and should be addressed expediently or Hyundai may risk a significant class action lawsuit.

The emergency breaking system automatically engages whenever it feels it wants to. It has become extremely dangerous to drive the vehicle on a daily basis. I have been in contact with Hyundai, Hyundai consumed affairs and have brought the vehicle back to two dealerships to see if they can duplicate the problem. They have been incredulous thus far and still I am left with the safety issue. I feel very scared to drive the vehicle. I am not sure what to do at this point because Hyundai said if they can’t duplicate the problem then the vehicle is working as designed but is it going to take a serious accident for this to be taken seriously. It has been happening since September 2025. Thank you.

I started to accelerate from a full-stop to turn left at arrow onto highway ramp and car's emergency brakes came on with a real jolt - almost rear-ended by semi behind me. So scary. So dangerous. Backache, now, too.

The automatic emergency braking system, I think it may be called (or is a part of) the forward collision avoidance system by Hyundai, triggered incorrectly while on interstate 265. My car was travelling at about 35 mph on the off ramp when the automatic emergency braking system triggered and cause my car to rapidly decelerate to a near standstill. The vehicle following behind me had to swerve into another lane to avoid hitting my car. The problem has not been reproduced or confirmed by a dealer or service center. The component has not been inspected yet, but we will be bringing it to the dealer in the near future. There were not warnings or messages that this was about to happen other than the emergency sound and light when the automated emergency braking engaged. This has happened twice before on other roads and in other situations with this car.

Customer of Hyundai 4 years now. Issues with the forward collison-avoidance assist (fca) on my 2025 tuscan, malfunctioning, aggressively breaking, fantom breaking when absolutely no imminent collision will happen, causing other drivers to come within inches of a rear crash with me, also the same fantom breaking while parallel parking. The breaking causes me to be thrown towards my windshield. Made appointment with a Hyundai service they inspected on a diagnostic machine and no recommended "codes" were available after test was done, no repairs made they said my car is fine. Happened again within 2 blocks of service center please help.

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.

The automatic brake system triggers when there is no obstacle. It has caused the car to stop suddenly in the middle of the road and almost become rear ended several times. We took it to the Hyundai service center and they said they’ve had complaints of this before but checked the system and don’t see any issues.

My wife was driving our Hyundai Tucson on the city street at about 35 mph. She signaled left to get into a turning lane. The turning lane has two lanes and is very long. She got into the turning lane and the traffic in front of her stopped. The car's collision avoidance system activated and slammed on the brakes even though the vehicle was not very close to the cars in front of her. As a result, a vehicle behind her rear ended her causing over $9,000 in damage. This car has done this before on the highway and city street. The collision sensitivity setting was on normal and had been since we got the car and until the accident. I had also been driving the car when the collision avoidance activated. The problem with this car is that it only knows to slam on the brakes and results in getting rear ended. It does not gradually apply the brakes even when the car in front is not very close and locking up the brakes is not necessary and is actually unsafe as shown when my wife was in a rear collision accident. This is a major safety problem and needs to be looked into.

The automatic braking was inappropriately applied while I was coming to a controlled stop on a 45mph stop light intersection. I was already slowing down and about 30 feet behind the car in front of me the collision avoidance warning starting going off, slightly applied brakes (to the additional amount I was already applying) then slammed on the brakes to a complete stop. There was some teen behind me who wasn't paying attention, and obviously no one expects the car in front of them to slam on their brakes 30 feet behind the cars in front of them, then plowed into back end of my car. This isn't the first time it's happened and I wasn't even at risk of collision as I was already slowing down in the other instances. But this time it caused an accident and injury. I am suffering from whiplash and possible herniated disk. The system is on the late setting as well but is still dangerous to drive. There needs to be a firmware update or sensor recall, this is very dangerous!.

The contact owns a 2025 Hyundai Tucson. The contact stated that while his wife was driving at various speeds, the imminent crash braking failed to function as intended. The first time that the failure occurred, the contact's wife was driving in the rain, and a beeping sound was coming from the vehicle, and the vehicle stopped independently. The vehicle returned to normal functionality after several minutes. The contact stated that on a separate occasion, while his wife was driving in slow traffic, there was an abnormal beeping sound coming from the vehicle before the vehicle independently stopped. No warning lights were illuminated. The vehicle returned to normal functionality minutes later; however, the failure persisted. The vehicle was not taken to the dealer or an independent mechanic, and the vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 1,000.

2 times, while driving 35-40 mph, the vehicle automatically slammed hard on brakes to full stop without any danger or other vehicle near, causing neck pain/whip lash. 3 days ago, I attempted a u-turn in busy intersection, suddenly the vehicle braked hard and came to full stop without any danger near. The dash lights lit up, the vehicle stalled. I was in middle of very busy intersection. It would not move forward. I reversed just in time to miss being slammed into by fast moving oncoming traffic.

We were driving on i4 in stop and go traffic. Our speed was under 25 mph and we were over a full car length back from the vehicle in front of us. I was actively braking to come to a stop due to traffic and the forward collision / emergency braking kicked in and stopped us immediately. This caused a car behind us to almost hit us and cause an accident due to sudden stopping. This happened 3 separate times within a 30 minute timeframe with 2 different cars behind us. The system will take control of braking the car and the steering wheel, and will not always give it back immediately to be able to continue driving. This has occurred previously when slowing down due to someone turning in front of us just in every day driving, and has almost caused a wreck then as well. Our local Hyundai dealer said there was no recall or issue with the system. This is dangerous and going to cause an accident sooner or later.

On numerous occasions (over 20) the forward collision system just slams on the brakes to a full stop, there was nothing close enough to vehicle to cause this issue. Sometimes it’s caused by rain or wind, sometimes for no apparent reasons. One time it caused a no damage accident as person behind me tapped my bumper. In traffic it is set off often with nothing within a safe distance away. There was no obstacles or sudden movements from other vehicles around me. I have brought the car back too Hyundai 3 times only to tell me either a dumb excuse or nothing is wrong with vehicle. I have seen on forums there are a lot of incidents with this particular car we have serviced the vehichle 3 different times over this issue and were told there is nothing wrong with the vehicle accident happened in summer so I will say there was a crash in additional details but last date occurrence of automatic stop was this morning.

I was driving on the road this morning approx. 25 mph (clear road, no rain, snow etc. ) the car came to a full abrupt stop. Collusion/warning notification never came on (there was nothing in front of me) seatbelt locked. Car would not move. I put the car in park and had to turn the car off and back on to get the car to move. This honestly scared the life out of me. I had several cars behind me that could of rear ended my car and caused serious harm to myself or other drivers. I called the dealership (will be dropping off this evening) but they made it very clear that if they can not duplicate the problem there is nothing that they can do. The car has 8,000 miles on it and was purchased in April 2025.
