Warnings Problems of Hyundai Tucson - part 1

I was driving along a 40 mile an hour road and there was a fork in the road and a car in the opposite lane waiting to turn onto that fork to the right and the car just slammed on the brakes and I was injured very badly. My neck back and hips are hurt very bad.

I have a 2026 Hyundai Tucson 2500 miles. It has slammed on the brakes. At least 6 times since I've owned the vehicle for forward collision to the point where it could have put me in danger. And I could have been in an accident one time it occurred when I was making a curve, there was oncoming traffic from the other side in the curve. And the vehicle slammed on the brakes bc of the other car going in the opposite direction at the car. And just yesterday, as I was slowing to a stop at a stoplight, if there was a car in front of me going less than 15 miles an hour. So I can slow down so I could stop it slammed on the brakes. Despite the fact that the car in front of me had already left his stopping point again dangerous. I had a seat belt mark on my shoulder. Because of it.

Driving on major highway during rush hour traffic the SUV locked up due to the automatic front break system I couldn’t even turn to avoid the crash. I was rear ended from behind.

Forward collision assist is dangerous. It engages when not necessary and has almost caused several wrecks by slamming on the brakes. There needs to be a way to permanently disable and not have to pick through a series of menus every time. Also, lately I feel like I’m fighting the lane keep assist when I’m on the highway, and it tries to move when not necessary.

3 incidents of same braking component. Once while exiting a parking lot, the car slams breaks so hard while accelerating that car slams to hard stop with no warning. Once while driving through an intersection brakes engaged for no reason. Once after stopping at red light, then when moving with traffic, car stops so hard with no warning that we were almost rear ended and seat belt left marks and bottom of car seemed to hit the ground. These violent automatic breaking events are scary because for no reason or cause and no warning the car suddenly hard brakes. Fear of being rear ended or car flipping from such sudden and hard breaking. This incident has not been inspected although the car is current on all maintenance and has been recently in to car dealer for oil change.

I experienced forward collision warning active three timeseven when the car before it's far more mine and one time it used automated emergency braking.

My car abruptly stopped due to the emergency braking system when the car in front of me braked (hard) but I had more than enough time to stop without having the emergency braking system engaged. Due to this, the car behind me hit me from behind damaging my bumper, trunk, and back lights.

In August/September 2025 my mother's Tucson would randomly shut down on her (completely stall while driving) and she would not be able to turn it back on. If she waited a little while, then she would be able to turn the car back on but it was unknown when the issue would happen again. We took it to the dealer several times after each shutdown and the dealer stated it was not throwing a code and they could not diagnose the problem. The last time we took it to the dealer, the vehicle shut down while they were test driving it and they discovered it was a rear wheel sensor which is part of the abs system. When the car would stall, lights on the dashboard would start flashing and the car would shudder to a stall. Since repairing that rear wheel sensor, the car has not exhibited the issue until 3 days ago when it again shut down randomly while she was in traffic. This, of course was terribly frightening for her as cars were honking at her and whipping around her vehicle. She was not able to get the car started. A police officer came and parked behind her car, calmed her down, and got her to try the car one more time and it did start up and she was able to proceed to the closest parking lot. After that we followed her home and have an appt. Set to go back to the dealership. We are expecting the same run around at the dealer who charges excessive fees to diagnose and then repair the car. My mom is [xxx] so this is a dangerous vehicle for her to be driving (really for anyone) as I am reading on line others reporting this same condition. I am expecting that they will find that a different rear wheel sensor has failed for which they will want another $800. 00 to repair or maybe more now. Obviously we must get rid of this vehicle. It has less than 25,000 miles on it because she only drives to the grocery store and back. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The forward emergency braking system on this vehicle is a hazard not a safety feature. I have almost been rear ended 3 times because of it and have had my neck and back hurt from the quick sudden stop! I was not even at risk of getting into an accident! this feature needs to be permanently disabled! I still owe 30 payments on this car but will be getting rid of it if I can't disable this permanently.

The fca engages in situations that are not dangerous. There is a slamming of the breaks which causes items in the car to fly off the seat and nearly cause the cars behind me to rear end the car. This is a dangerous situation and has happened about 6 times since we purchased the car less than six months ago. There is not a way to permanently disable this supposed safety feature.

This is a recent purchase. The forward collision braking system seems to be too sensitive and the braking is so immediate and abrupt it threw everything in my car forward including me, causing minor back pain. This has happened several times with the most recent being yesterday. I was no where near a car or potential collision each time. Yesterday, while driving on a busy highway, I had plenty of distance and it did it again nearly causing a car to rear end me. It was such an abrupt stop everything flew once again to the front of the car. The way this vehicle stops is going to cause an injury to a driver. Mark my words. It stops with such force that it throws the driver forward.

What component or system failed or malfunctioned, and is it available for inspection upon request? automatic braking system brakes for no reason when I am not near any cars traveling at high speed or even when I am already at a complete stop or moving very slowly but not anywhere near hitting the car in front of me. This has happened multiple times since I leased this car in July 2025 and it seems to be getting worse. I had a 45 min drive home today and it happened about 7 times all for no reason. How was your safety or the safety of others put at risk? it slams on the brakes unnecessarily and the cars behind me almost rear end me. This has happened on residential roads and highways. Has the problem been reproduced or confirmed by a dealer or independent service center? I just called to take it in. They seemed to have no idea what I was talking about. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? not yet but I am taking it in ASAP were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? none.

Was slowing down for traffic in front of me and my brakes were applied automatically from the crash impact sensor and I was rear ended.

I have experienced the emergency braking system warning and sudden application of my brakes when traveling at highway speeds for what seems to be no apparent reason. I thought it had to be a glitch related to just my car; however, this has happened twice in the past month and it is an unnerving experience. As I just read about this same problem occurring in later models of my car I want to document that this same problem exists in my 2022 Hyundai Tucson.

I was on the freeway about 2 minutes and the car flashed a red warning then slammed on the brakes and I flew forward. No cruise control and no buttons hit or anything automatic. Another time,  I was merging to freeway on ramp (with 2 lanes merging and going to freeway). I was on the left right lane towards the on ramp and another car came speeding next to me on other the on ramp right lane. All of a sudden, my Tucson says emergency braking for about 1 to 3 seconds.  slamps the brakes. I am not sure if the other speeding car made a sensor think I was going to merge into him,or him into me, or the sensors didn't detect the lane markings. It's my daily route to this ramp and it has not occurred in the past. These emergency braking incident has happened several times (4-5 times in a month) to me, usually during a highway drive similar to those above. I have to turn off the forward collsion to stop this happening and it comes back on everytime when the car starts from a off.

This incident occured in the woodlands, texas, about a 45 min drive north of my home. I was headed south on [xxx] . I had pulled into a left turn lane at the intersection of [xxx] . After the oncoming traffic had cleared, I proceeded to make a left turn onto [xxx] . My Hyundai Tucson slammed on the brakes just as I entered the oncoming lane. The fca was off. I was able to hit the gas and start moving forward again before any oncoming traffic got to this intersetion. There was no warning before the brakes were applied. Note, the fca safety function was absolutely positively turned off. We have gotten into the habit of turning it off to avoid these unintended, unexpected sudden complete stops. Now I'm concerned the fca system has more problems than just being overly senstive or malfunctioning causing numerous sudden braking issues. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was stopped behind another car in a through-lane in the parking lot at marshall's. I was fully stopped about 1 car length behind another stopped car. I decided to make a left turn (from my stopped position) into a perpendicular through-lane in the same parking lot. Just after I drove my entire car to the left of the parked car, my Hyundai Tucson slammed on the breaks. There were no cars coming toward me in the oncoming through-lane. There were no cars in front of me or coming toward me in the perpendicular through-lane. The fca was off. Again, I don't understand why the car is appying the brakes while I'm going forward if the fca is off.

What component or system failed or malfunctioned, and is it available for inspection? the forward collision avoidance (fca) system malfunctioned. The front camera system appears to have triggered unintended hard braking beyond normal driver input. The vehicle is available for inspection upon request. How was safety put at risk? while approaching a vehicle in front of me, I was gradually slowing down and applying the brakes normally. Without warning, the vehicle suddenly applied significantly stronger braking than intended. This abrupt and excessive braking caused the vehicle behind me to collide with my car, creating a dangerous situation and increasing the risk of injury. Has the problem been reproduced or confirmed? unknown. The issue has not been reproduced since the accident, and it has not yet been confirmed by a dealer. However, the incident is consistent with Hyundai recall NHTSA campaign number 26v316000, which describes unexpected and premature activation of the forward collision avoidance system. Has the vehicle been inspected? the vehicle has been inspected by insurance representatives following the accident. It has not yet been inspected by Hyundai or a dealership specifically for this recall-related issue. Were there any warning signs before the failure? there were no warning lights, alerts, or messages prior to the sudden braking event. The braking intervention occurred without advance notice. Additional description of incident: at the time of the incident, I was approaching a vehicle ahead and applying the brakes gradually under normal driving conditions. The vehicle then suddenly applied much stronger braking than expected, consistent with automatic emergency braking intervention. This abrupt deceleration caused the vehicle behind me to rear-end my car. This behavior matches the defect described in Hyundai recall 26v316000, where the forward collision avoidance system may activate unexpectedly and apply excessive braking.

What component or system failed or malfunctioned, and is it available for inspection upon request? forward collision warning how was your safety or the safety of others put at risk? the car braked on the highway and caused me to get rear ended. Has the problem been reproduced or confirmed by a dealer or independent service center? no has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? this occurred twice in the same day, the second time it caused an accident. The first time was on a busy highway, someone braked going 75 mph in front of me and the car "over reacted" and braked so hard the people behind me had to swerve around me. The second time we were in stop and go traffic and it unexpectedly brought me to a complete stop and the person behind me hit me.

Multiple times the vehicles forward collision system has slammed on the brakes almost causing rear end collisions. Usually will occur when vehicle in front begins to brake, but the car will slam on the brakes to a sudden stop rather than coasting to a stop. This will occur even while my foot will be pressing the brakes.

The forward collision assist system applies hard braking when there is no danger. This happened twice today at low speeds (1-2mph) once in a drive through and once in traffic in a parking lot. Luckily, the truck behind me did not rear end me. My concern is what if it starts doing this at higher speeds? I feel it is dangerous.

As of today, March 17, 2026 , my 2025 Hyundai Tucson keeps having safety issues. On March 8th , 11th, 14th and 25th the car once again shut down mid-drive. This issue occurred last month as well but dealership claims no dtcs were found. I am noticing that the forward collision warning comes on without any cars or objects in front periodically since the purchase of my car. The light will remain on for a few seconds and disappear. The automatic brake system seems to be causing issues as well which I believe causes the car to shut off completely mid-drive. Once the car shuts off the panel lights turn on to include the engine light, but then after a few seconds I able to change gears back to park in order to turn car back on and continue driving. This has happened now several times since last month. However, I have had issues with my brand new vehicle since I purchased it last year. My car remained in the dealership for 3 months last year due to an engine, ac and power train issues. Prior to the car shutting off, no actual warning lights illuminate other than the forward collision warning light and the notification of headlights are turned off even though it’s daylight and headlights do not need to be turned on . Periodically and intermittently an alert about consider taking a coffee break alert has also popped up in the past. It seems Hyundai has a severe issue with the fca operating system and over 100 complaints have been made about this vehicle nationwide and no recalls have been issued. I am afraid for my life and the life of others on the road as this car should not be stopping and shutting off while driving for no apparent reason.

I rented this vehicle for 5 days. In those 5 days, twice while driving on the highway (at 5-10 mph under the posted speed limit due to heavy traffic, dry and clear weather), I found it necessary to brake hard due to other vehicle traffic braking hard in front of me. When I had slowed down sufficiently and felt I had sufficient space between my vehicle and the one in front of me, I let off the brake pedal, but the "forward safety" feature continued to brake until the vehicle came to a complete stop nearly causing the vehicle behind me to hit my vehicle. To be clear, no accident occurred, but in one of those instanced the vehicle behind me was within ~1ft of hitting my rear bumper. Had the vehicle behind me not been able to stop in time, there would have been an accident, and because the brakes were locked by the computer, I could not have done anything to prevent it. After the second incident (on 2-15-2026), I looked through the vehicle setup information and found it is possible to disable the "forward safety" feature to prevent additional incidents, however, that setting can only be changed then the vehicle is stationary, and it automatically turns back on every time you start the vehicle.

Driving south on a busy 4 lane divided city street, as I approaching an interestion I initiated a right had turn with about 1 car length gap in front of me. I was driving about 5 mph. The car suddently applied the brakes to a full stop. The car behind was able to stop in time and not hit me. There was no risk of me hitting the car in front of me.

I was in stop and go traffic on the highway. The car in front of me started going and I did as well. At this point, I was at least 3 car lengths behind them. They braked fairly quickly and I was as well. When I was braking, the fca emergency braking enabled super prematurely. The result of the emergency braking caused the vehicle behind me to rear end me. My car has since been repaired, however this is super disappointing on a brand new car with 500 miles.

The automatic braking that happens when the car sensor thinks you are too close to another car is dangerous. This has happened to me three different times when there were cars in front of me turning right. There was plenty of room and the car was turning so I was following, and it not only slams on the brake and makes you stop, but then it takes it a minute to reset before you can move again which then can slow traffic. I was almost rear ended two of these times. It is unsafe. You can manually turn it off, but you have to re set it every time you get in the car. I have seen many complaints about this occurring and causing people whiplash as well due to the sudden stopping on Hyundai sites.

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).

At dusk I was driving below the speed limit (40 mph). I was at least 3 car lengths behind the vehicle in front of me when I saw the driver was braking because his brake lights came on and there was an intersection ahead with a stop light. There were at least two cars ahead of the vehicler I was behind. I braked but the car kept on going and appeared to accelerate. I was unable to stop the car with the brakes and collided with the car ahead. It was a sturdy vehicle with a strong bumper so I did not do much damage, if any, to the vehicle but my car requires $6,645. 90 of repairs. No one was hurt and the air bags did not deploy. I was wearing my seat belt. There was no warning from NY vehicle that I was getting too close to the vehicle ahead and my car made no attempt to brake automatically. It was as though all warning indicators were not functioning. I have had two other incidents of the car surging ahead but did not report it because no one else was involved and I was able to correct the speed and I thought it was just my imagination.

I have had my car for a few weeks and have almost been rear ended 2 times. The first time I had the forward safety timing set at standard and the second time it was set at late. In both instances I was fully at a safe distance from the car in front of me and was applying the break myself. Upon investigating it seems like this is a common problem. Like it is too sensitive to the break of the car ahead and too harsh on its own breaks. I would like to be able to keep this feature turned off and not have to reset each time I start my car. I feel unsafe that the safety feature will actually cause an accident.

The driver attention warning is not disabled, even when doing exactly that in settings. This is incredibly annoying and distracting and is a major reason I cannot recommend this car to others.

The car in front of me, 8 to 10 feet ahead, slow down and turn on their blinker. My car slammed so hard on its break. It threw me and my dog forward. It never gave us a warning until it slammed. There was plenty of time for me to slow down, but also the car was partially already in the turn lane. There is then 223 seconds where my car will not move forward. I am a sitting duck to cars coming behind me.

I was travelling east in the left kane on the southern state parkway in long island, NY. The car in fron of me stopped short. I had plenty of time to slow down, then my car brakes locked up and I was almost rearended. Fortunately the driver behind me was alert and moved to the shoulder to avoid contact.

Multiple times the car has locked the brakes when there was a car several car lengths in front of me. This has resulted in me nearly being rear ended three different times. The force of the stop has also caused me to have neck and back pain. This is u safe and will result in injuries. There are many reports about this on reddit.

I’ve been driving this car for nearly a year, and during that time I’ve had multiple incidents where the forward collision-avoidance system applied sudden hard braking when it wasn’t necessary, creating dangerous situations. I don't think I will be fortunate every time. I believe there is a serious issue with how the Hyundai's fca system is operating and it needs to be investigated as a priority. Currently I am driving with it turned off every time I start the car. On my research I found this issue has been reported by multiple other drivers as well and I don't see any acknowledgement or reference from Hyundai on this so far.
