Automatic Emergency Braking Problems of Hyundai Tucson - part 2

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.

3 times my car have braked while im driving causing my whole car to jerk 2 of the time I hit my head and my knuckle and finger got hurt and was bleeding I have pictures but they are not allowing me.

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.

1. The component/system that failed appears to be related to the vehicle’s braking/safety assistance system, which is now associated with the recall affecting certain Hyundai Tucson vehicles. At the time of the accident, the vehicle suddenly became difficult to control during highway driving, which ultimately resulted in the crash. The vehicle was declared a total loss, but insurance records, photographs, and inspection documentation should still be available upon request. 2. My safety and the safety of others were put at serious risk because the vehicle lost stability/control while I was operating it on the highway. The accident caused the vehicle to flip, resulting in injuries and creating a dangerous situation for myself and surrounding drivers. 3. The issue itself was not fully reproduced prior to the accident, however the recall now issued by Hyundai appears to involve the same or similar malfunction connected to braking/safety system concerns. The vehicle was inspected after the accident through the insurance process and body shop estimates were completed before it was declared a total loss. 4. The vehicle has been inspected by insurance representatives, towing personnel, and others involved in the claims process following the accident. Police also responded to the accident scene and completed an accident report. 5. Prior to the failure/accident, there were no clear warnings that would have indicated the severity of the issue. If applicable, there may have been occasional warning indicators or abnormal vehicle behavior before the crash, but no information was provided to me at that time indicating the vehicle was subject to a safety recall. The emergency brake has been horrible since I’ve purchased the car, I’ve almost crashed or gotten hit numerous of times.

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

I purchased the car about 30 days ago. In that short time on two occasions, with absolutely no reason the 'forward safety warning system' engaged and applied the brakes so severely that on both occasions I narrowly missed being rear-ended. Fortunately, all vehicle occupants had their seat belts on, otherwise we would have been thrown around the car. In the first occasion my husband was driving about 50 mph and bam wham! totally out of the blue the car throws itself into a complete stop for no reason. . . He was not close to any car. The second time happened today. I was in traffic going about 15 mph and bam wham! the car slammed on the brakes and everything in our car went flying around the cabin and the car behind me had to evade from hitting me. I am afraid to drive this car under this situation. I saw I can turn off the braking system - but it only works for each ride and will come back every time I start the car. This is very very dangerous and is an accident waiting to happen. I wish I could give the car back.

The brakes pushed down to the floor before the collision and wouldn’t stop the car my passenger was injured no warning system on the collision prevention and nothing engaged my foot was on the floor and there was about a 10 second delay before the brakes kicked in it’s all on dash cam.

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.

Driving to work, going into a turn with no obstructions my car frequently alerts to a "collision warning" that is not there. Additionally, I have been driving on the highway, with no obstructions in front of me and my car emergency brake despite an emergency not being present. In both instances, it is extremely distracting and induces anxiety as I am alerted of a threat that is not there. Further at highway speeds (65-70 mph) on the highway, and braking despite having no emergency nearly caused an accident. I was able to push further down on the gas to force the car to keep going to not stop on the highway. The collision warning has been an issue since purchase of the car in June 2024, the emergency brake occurred in February 2026.

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.

I was driving on the highway with no one in front of me. The car suddenly slammed on the brakes and flashed "emergency breaking system" on my dash. My car went from about 75 mpg down to 50. The car behind me almost rear-ended me. He then proceeded to pass me and brake check me because he thought I had deliberately brake checked him. This incident caused the man behind me to get road rage and react dangerously to me. I hit the gas and it finally stopped breaking and let me gain speed up again. It was terrifying. This is not the first time this has happened but it was the first time in the highway. It has happened several times on side roads for no reason either. I have an appointment with Hyundai to figure out what they can do because I don't feel safe driving this car.

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.

Purchase my new car December 2026. My car has done that with people are calling phantom breaking three times since I bought the car within the first month and a half. I was doing [xxx] the first time and there was nothing there and it just dead stopped what if somebody had been behind me and I caused it big accident? it happened again when I was doing [xxx] and it just dead stopped with for no reason. I purchased this car because I have a concussion cuz my former car was totaled I feel like the safety feature is a safety hazard and I'm scared because I have a concussion and a neck injury that it's going to cause more damage. I have to click the button to stop the front assist so it doesn't happen. I took my car in to the shop where I bought it at bud clary in auburn and they said that there was nothing wrong with it that maybe my good to go pass was in the way which I didn't even have my good to go pass up yet at that time. I'm scared and I just bought this car. I wish I hadn't but then I see that Honda is having the same issue. They need to come up with a fix. They said that the calibrated it and it was fine that they made some dang excuse but it's scary and I'm afraid to even drive my car information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

I was driving down the highway going about 60-65mph with cruise control and lka on. I turned my blinker on to switch lanes, checked my blind spot, and moved over to the left. As I was doing so, a semi switched lanes from the left into the right (my new lane) right in front of me. The truck then slowed down a lot, and usually my forward collision warning would say something if my adaptive cruise control isn’t on (or is and I’m just going too fast to slow down) neither of those things happened. No warning. No automatic brakes. No slowing down. I tried to engage the brakes manually but nothing happened. I slammed into a semi at around 60mph because of 3 different system failures. Not only did I hit the semi at 60~mph, apparently my brakes didn’t work at all and I spun out until I hit the concrete barrier on the highway. If my brakes had engaged automatically, I could have slowed down enough to avoid the collision altogether. And if they had engaged manually I could have at least minimized the damage to my vehicle (and myself) because I wouldn’t have hit the concrete barrier as well.

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.

During the winter, my car would activate the forward collision warning and automatic emergency braking while I was driving when there were no other vehicles in front of me or even around me. It happened several times over a few day timespan, at the time I thought it was because I had gotten a car wash when it was colder weather and maybe the water had affected the system but now I see that there is a recall for this same issue.

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 slowly pulling into a parking spot, when at about 10ft from curb the car suddenly accelerated faster than she even thought the car even was capable of (the awd likely helped). It hopped the curb and hit a tree. She backed it up to the parking spot (it acted normally) and had it towed to dealer. In hindsight, the car had been having a progressive amount and frequency of delay in normal acceleration, sometimes having a pause of up to second or two from pedal input to car response. We asked the dealer to check the edr (event data recorder). The tech first said he didn't even know what that was, then that he checked with all his fellow techs and they didn't know either, then the story changed to the model not having an edr. We politely told him which page in the Hyundai manual he can find it, and he refused to look, as did his boss. Car was transferred to a body shop, and disposition was to total the vehicle. While the body shop was still evaluating the car, we contacted a second dealer, who said they don't have a reader. I inspected the floormats before the car was towed, as that was an initial suspect, but it was locked in and clearly there was no obstruction. She was wearing tennis shoes and doesn't recall ever having an instance of hitting the wrong pedal in any vehicle. She thinks she was only coasting, not even touching the brake yet.

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.

Vehicle randomly activated automatic emergency braking and the forward collision warning with no other vehicles in sight. The vehicle slammed on the brakes almost causing a trailing car to rear end our vehicle. This has happened 5 times with speeds between 40 and 80 mph over the past 4 weeks. Conditions were cloudy. Problem has not been reproduced by the dealorship. No inspections have occurred.
