This has happened twice now. When going at a low speed, once in traffic, once while performing a U-turn, while braking, the car is trying to accelerate. I have to practically stand on the brake pedal to avoid the car lurching forward. I saw no warning lights on the dashboard. I haven't yet brought the vehicle to a dealer or service center, but it will be.
Automatic emergency braking stopped the vehicle because another vehicle in front turned right.
The Manual Speed Limit Assist, or MSLA, feature unintendedly activated while I was driving, nearly causing a collision. I was initially unable to deactivate this steering-wheel based feature, as: (1) I did not intentionally press any buttons to activate it, and: (2) I had to balance the need to visually monitor other vehicles on the highway to avoid a collision and simultaneously figure out how to cancel this feature, which places a limit on the speed that the vehicle can travel. Instead of claiming that this feature malfunctioned, I am claiming that it is an egregiously, poorly designed and dangerous feature. The button to activate it is located on the steering wheel; consequently, a driver can easily activate it without meaning to do so. This inadvertent activation happened to me twice, each time impeding, however briefly, my ability to safely navigate a busy road. This feature was not identified when I purchased the vehicle; however, earlier this year Hyundai belatedly sent a letter to its customers titled "Understanding Manual Speed Limit Assist (MSLA) Feature," pointing out how to activate and disengage the feature (and providing a link to a website for a tutorial with more information: [XXX] .

The same incident has occurred 4 times ( [XXX] While driving on the freeway in light traffic and no vehicles in front. The forward collision sensor triggered dropping the vehicle in speed approx 30 mph almost instantaneously. This is San Diego so no snow, rain or sleet and we were driving eastbound each time with the sun at our back. Hyundai kept the car for a week for diagnostics and found nothing. We have since escalated to corporate and are going in for another round of diagnostics. We have been exceptionally fortunate that we were not rear-ended. We have since installed a dash-cam to record the next event INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While operating the vehicle, an intermittent audible warning sound occurs without any corresponding alert, message, or notification displayed on the dashboard or infotainment screen. The specific component or system causing the warning is unknown. The vehicle is available for inspection upon request. This condition puts my safety at risk because the unexplained warning sound occurs while driving and causes me to divert my attention from the road in an attempt to identify the source or meaning of the alert, creating a driver distraction. The issue has been reproduced multiple times under normal driving conditions. I demonstrated the condition to the dealership and provided video evidence; however, the issue has not been diagnosed or confirmed, and no root cause has been identified. The vehicle has been inspected by the dealership, but no explanation or resolution has been provided. The manufacturer is aware of the issue through an open case. There were no warning lamps, messages, or prior indicators associated with this condition. The audible warning occurs without any visible alert or explanation. The condition began shortly after purchase in November 2025 and was later documented and demonstrated to the dealership in January 2026.
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.
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.
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.
At high speeds above 40 MPH vehicle automatically brakes with no vehicle or objects in front while vehicle is in operation. Very concerning when driving on interstate.
The contact owns a 2024 Hyundai Tucson. The contact stated that while operating the vehicle, the manual speed limit assist erroneously activated causing the vehicle to suddenly decelerate, and the vehicle failed to exceed 20 MPH. The cause of the failure was not yet determined, and the vehicle was not repaired. The manufacturer and local dealer were notified of the failure. The failure mileage was 40,000.
My wife and I purchased a 2024 Hyundai Tucson in June. Since February 28, 2025 the SRS indicator lights have come on twice. Hyundai replaced the airbag twice. In March, the emergency brake system red lights illuminated, and the car came to an abrupt stop. Luckily, there were no Cars behind me. Seconds later, the car resumed, and the lights disappeared. Hyundai dealership took the car in and returned it in two hours noting they could not duplicate. Several days ago, the same thing happened with the emergency brake system. Driving at approximately 40 mph the car slammed on brakes and the dash illuminated again. No cars behind me. The dealership returned the car once again, noting they could not duplicate. The car has less than 8000 miles. I won’t allow my wife to drive more than 10 miles alone. It’s unsafe. The manual states the car is not to be driven with any of the sys indicators on and to do so would cause serious injury or damage to the car. I will send attachments of invoices, NHTSA complaints and Hyundai manual info about unsafe condition.
Owner [XXX] [XXX] . Driver [XXX] [XXX] ) [XXX] All of a sudden my 2024 Tucson vin: [XXX] gages indicated emergency braking for about 1 to 3 seconds and the front end went down ,(my wife and I went foward ) as though I was stopping (scared me ). It was the forward collision avoidance sys. I was so happy no one was behind me. Avoided a rear end collision. [XXX] we were Traveling west in the left lane of a three lane highway. I released the gas pedal to make a left turn in a left turn lane. The light was red. No one really behind me or to my left. Only one car to the right of me in another lane. This is dangerous! This is my wife’s car. Enough said!!!! Car was at the dealer for a couple of hours. They could not duplicate. Said it could have been my floor mat “that made my emergency lights come on the dash.” “STUPID” This occurred the day after picking up my car from the dealer. Feb. 28, Hyundai replaced the Air bag. STS light came on. Picked the car up Monday. Today [XXX] Thursday) the STS Airbag light came on again. The bag was replaced again. [XXX] the front collision sys emergency stop sys alerted again. Again, Hyundai declared they could not duplicate. This is an unsafe car. A death trap. Hyundai warns death may occur if using while driving can cause death. They also warn us using the emergency brake while driving may damage the brakes or cause a collision. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Driving 70 on the interstate without any cars in front or side of me and car auto hard braked down to 60 and red emergency brake light was on. An 18 wheeler was behind me. Luckily no injuries or accidents happened.
As I am driving on the Garden State Parkway on sunny days and rainy days at approx 70-75 mph the Emergency Braking System notification activated on the dashboard in red, a noise activates and the car feels like it is going to stop short. This seems to occur about one and a half hours into my ride There are no cars in front of me or directly next to me. This occurs randomly and has happened seven or eight times since I leased the car in December 2024. It is very scary and the service techs at the dealership where I leased it cannot duplicate the occurrence because it is random. I feel unsafe driving the car because I am afraid at some point the car may stop on the highway. As it is now it feels like it is going to stop because it slows down.
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
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.
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 [XXX] 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.

Sudden loss of speed for no reason. was traveling at 35 mph when vehicle suddenly dropped to 22 mph. Stepped on gas with no response. I know the 22 mph because it showed up on warning illuminator. Car behind me almost hit me because he had no indication (prior warning). Turned off at closest exit, turned vehicle off then on restart things were normal. Took to dealer and they found nothing in computer code or mechanical to explain why this happened. Am an older women afraid what will happen if repeats on highway going 70+ mph. Please made Hyundia find and fix.
Car throttle, AC, Cruise control, car transmission and gears not correct, radio turns off completely and messes up CarPlay. Also no updated radio. Scary car is still new with all of these issues.
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.
Two incidents while driving on the highway. 1. Emergency braking activated on its own. No cars around me. It was a rural area. The red emergency braking activated light showed up and my car braked but resumed driving. This is a new car with less than 4k miles on it. 2. The hands free assist and cruise control were activated. My care swerved to the right abruptly. My hands were on the wheel and I was able to correct this but this is very concerning as my daughter drives this car on mountain roads when she is going to college. I have read online reports when others driving the same make, model and year vehicle.
Forward radar sensor pass side lower grill/bumper area. 1st told a sensor recall but after 3 hrs and then seeing the vehicle in the shop with the entire front bumper clip removed the sensor was out of its driver side socket and 1 side flopping around which may have caused a small dimple from the inside to pop out on the 6x5 cover that is the entire lower rubber/plastic black bumper/grill. Told the vehicle was hit, YET no visible damage to bumpers or painted surface can be found by their 2 dealerships and their 1 body shop, + 2 mangers, and 1 independent collision shop.1 manager drove the vehicle 10/11 and stated after "is operating as it should". Warnings have come on again since then refueling at additional 77 mile and then at 92 miles 10/14. Hartford ins has been notified and pending I hope an inspection. Vehicle purchased 1st March 2024, 1st warning at 5336mies currently at 5421 miles. They triggered the service engine light and stated via onboard computer it was an issue with a lower front driver side radiator something that may have been bumped while taking off the front clip, which they chipped and area and left a bit of gap at the fender connection. Other than the small dimple on the plastic from what I believe the sensor had been bouncing against, there is no damage. A safelight windshield company stated there is a notice/recall on the "auto headlight sensor on dash" but they do not cal them, only the optic sensor top center of windshield. BUT per the manual that top sensor plus lower radar can control the forward crash, cruise setup and auto braking. Need some help since my firm works with all auto/tire mfg and conducts DOT tire testing for USA and worldwide independent firms/gov's.
Sudden hard breaking for no reason. It's happened 3 times when in cruise control. If a car had been close behind it would have caused a wreck. I've had the vehicle just over a month
The contact owns a 2024 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle was hesitating during acceleration. While accelerating, the vehicle failed to exceed 3,000 RPM. Thee contact stated that while driving 45 MPH, the vehicle decelerated to 25 MPH independently while depressing the accelerator pedal. The automatic start button remained illuminated. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 8,800.
While slowly pulling into a parking space at a local shopping center, my 2024 Hyundai Tucson Limited suddenly accelerated while I still had my foot on the brakes to stop. The acceleration was so sudden and intense that I had to swerve to avoid a head on collision with a car parked in front of me. It took me a few seconds to gain control of the car, as the engine was revving at a high acceleration rate and the brakes were not working as they should. Just as suddenly as it happened, it then stopped and I was able to regain control of the car. Had there been other cars in the parking slots nearby, there would have been no to way to avoid a collision.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
