I have had two incidents with this vehicle (that I have owned for less than 90 days) that have raised safety concerns. Both involved the loss of all information on the "instrument panel" aka dashboard. In the first (August 18, 2025), all of the warning lights came on, then the screen went dark - there was no information on the two screens and no head's up display. This happened while I was on the highway doing about 65 mph. After I was able to pull over safely, it took several attempts to get the vehicle started again and in gear. I took it to the dealer the next day and they were unable to replicate the issue and saw no codes. The second episode occurred yesterday (9/6/25). This time the screen went dark except for a large red warning "no signal". The screen came back after a few moments; I am taking it to the dealer tomorrow. Both of these involved losing all information as to the speed of the vehicle - which I believe is a safety issue. Both of these issues have also been reported by others on facebook ("Hyundai owners") since late last year and it appears to be some sort of electrical issue but there has been no TSB or recall by Hyundai yet.

4th occurrence of the forward assistance warning system activating when we were at a slow speed with plenty of room to stop and the brakes engaged suddenly to stop the car and today someone slammed into the rear of our car. This is extremely frightening and should never happen at slow speeds when there is ample time to stop. My husband doesn't even want to drive this car again as he's afraid we may be killed. I see on the reddit site that this is happening to others too. Hyundai must fix this issue ASAP. You can temporarily stop this from working but everytime you stop & turn off car you must do it again. Police were called & report filed. We have to get our car fixed now.

My 2025 Hyundai Tucson had approximately 150 miles when the forward collision warning system has started to provide false warnings. The first event happened as I was pulling out of a parking lot where there was a dip in pavement between the lot and road. The dip in the pavement was interpreted as an object about to cause impact so my car automatically applied full braking. I almost got hit from the car behind me who was not expecting me to stop. Now my car has 406 miles on it and I routinely receive warnings about collisions due to nearby cars doing u-turns or cars which I will definitely not hit. A few times it has applied braking which has almost caused several accidents from cars behind me not expecting me to stop.

I was driving with my forward collision assistance (fca) disabled via the cars setup menu. The dashboard had an indicator light on confirming the fca was off. I was making a turn within a strip center parking lot and the car applied the brakes and the dashboard showed the “emergency braking” warning. As I was turning left into a lane with parked cars, a person was walking behind their car at least 1-2 car lengths in front of me on my right side. I’m sure this triggered the warning. 1) the situation did not call for applying the brakes. 2) the fca was off! I have been disabling the fca off each time I get in the car because of three other instances of unexpected and unnecessary full stop braking. See my previous report to NHTSA, same car.

When driving slowly on the highway and changing lanes the car sensed that we were too close to the car in front of us and completely stopped the vehicle. We were not all that close to the car in front of us and we were nearly hit by the car behind us as we stopped. We are concerned that this could happen any time. The car should never stop on its own.

Forward lane collision warning is dangerous. It fully stopped on the freeway during traffic and other times because it thinks im going to hit another car when I was rolling no foot on pedal. . There is no permanent way to turn it off. Has to be drone each drive. Dangerous and almost caused me to get into accidents.

Several times now the forward collision safety has activated and the car came to an abrupt stop. The car in front of me was braking and I was lightly tapping the brake pedal when out of nowhere the car started shuttering and came to a complete stop. This definitely scared me and I was relieved that the car behind me did not rear end me. I was not going fast by any means and I did not slam on the brakes as there was no need to. The forward collision is not a safety feature. This is a real problem and now I am scared of this braking design. I now deactivate this feature every time I turn the car on because there is no way to permanently dismantle this. Hyundai needs a recall to correct this.

Please see case 11675610 I have been told that this is for the same concerns I have my car is currently at the dealer for the third time to try and resolve this same issue dash will flash and go black for several seconds, when and if it comes back it will have all emergency lights on or flash no signal heads up display will also flash going blank this will be out for a longer period of time and is not always at the same time as the dash going out. When car is turned off after driving it will occasionally still show emergency lights on dash. Even after closing and reopening door, turning car back on and off safety concerns include but not limited to not seeing speedometer, safety lights and warnings.

The automatic emergency braking system went off when there was no reason for it to. It seems to think I am closer to vehicles than I actually am. It frequently warns that I need to brake when I don't need to, either because I am already stopped or because the vehicle that had previously been in front of me changed lanes. Today the vehicle braked so hard that I thought I had been in an accident for a minute. There was appropriate clearance between my car and the car in front of me and no reason to auto brake. I now have wipe lash. Hopefully they recall and fix this issue ASAP.

1 forward collision unexpectedly slammed on the brakes when I was trying to go forward to make a left turn. There was no one in front of me nor each side of me. I had 2x4’s in my car that were thrusted forward damaging my dashboard and display. I was told to take it to the dealership on Monday 2 I was fine just hooked up, but the driver was pissed off at me thinking I was stopping short on him 3 randomly the rear sensor would go off telling me they are too close when I’m at a complete stop. It has randomly stopped short on me but I thought it might have just been an over sensitive sensor. I have previously owned an ioniq 5 and the sensor would never stop going off even if I was 2 car lengths away. 4 the car is going back to the dealership on Monday so it has not been expected yet 5 exactly 6 days after purchasing the car the airbag indicator showed up on my dashboard while I was driving. I was used to the ioniq 5 sensors always going on when I was stopped waiting for a green light that I just thought it was the same way. It had abruptly stopped on me three other times between the 6th and today the 21st. I have only had it for 3 weeks. I have never gotten any warnings before the car just slams the breaks on. After looking online about this issue I decided to make a report before I take it to the dealership so you have it on file. I am very disappointed with this vehicle and was so excited when I bought it. I have been a loyal customer of Hyundai since 2017 when I bought my first ioniq and I have purchased 6 other cars for my family members since then. I still purchased the Tucson after having to take a 15,000 loss because the ioniq 5 never held its value. Now I’m wondering if I should switch manufacturers.

Car slams on the brakes while under controlled stopping. This has happened on a few occasions. Reported it to the dealer service department and was told it has happened to them and suggested that I turn off that option.

Not sure what failed. At around 8:30 am on a sunny clear day the driver was maneuvering slowly up a ramp between first and second floors of a parking garage at the college campus where the driver works. Driver paused the vehicle and slowly turned to the right to park in an open spot about halfway up the ramp. There was a large concrete pillar to the right of the parking spot and a low steel cable wall at the end of the parking space along the inner structure of the garage. While turning into the space, the driver described suddenly feeling "a loss of control of the vehicle" wherein it "felt like it was in neutral and wouldn't stop". The car hit the wall with extreme force, enough for resulting in minor injuries, damaging the frond end and a total loss to the vehicle. The force was enough to rebound the car back approximately 30 feet from the wall after impact. No help or warnings from the collision detection mechanisms was apparent. In a single prior time during the tenure of ownership (approximately 6 months) the collision detection system had intervened and manually stopped the vehicle on its own due to a car that had erroneously driven in front of the vehicle too closely. The car's lane assist successfully kept itself in lanes on most occasions. Several software related notices on the car dash had been reported during the tenure of ownership and in no case was the dealership able to figure out what was wrong in any of the scenarios, one of the software notices on the dash did end up just "going away" after some time.

Every time there is morning condensation/dew or rain, my front collision warning does not work. A notification pops up, the symbol comes onto the dash and it takes a good 3-5 minutes depending on the severity of the weather to have the symbol and notification go away and work. Also, 98% of the time when my car was preset to turn on, the emergency brake automatically engages every time I get into the drivers seat.

The driver attention warning is a dangerous feature that can't be turned off. It is constantly going off requiring that I take my eyes off the road to see why it chimed. I am a disabled veteran with an eye condition that requires me to wear very dark glasses in bright sunlight. The car is not drivable with my glasses on as the camera can't see my eyes. I was almost involved in a serious accident on i459. As I drove between an 18 wheeler and another SUV a red light on the dash and a message flashed that stated "regain control of the car". The system slammed on the brakes which caused the car behind me to almost hit me at 70mph. This occurred in heavy traffic at approximately 8:30 am. I almost lost control of my SUV.

The heads up display and dashboard randomly go blank for up to to 20 minutes at a time. During this, all alert warnings appear on the dash, no turn signals work, no sensor warnings alarm - no warnings of obstacles, no miles per hour are visible.

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.

On 2 separate occasions, the forward collision warning system activated. On both occasions I was under control of the vehicle with my foot on the brake approaching a vehicle that had slowed while entering into a round about. . . I was approximately 10 feet from the car in front going about 6 mph. All of a sudden several warning indicators activated (audible and visual) and then out of nowhere, all four wheels locked and my car came to a skidding/juddering stop. I immediately looked in rear view mirror fearing I was going to get rear-ended. The vehicle in front proceeded to move on and I tried to get myself together and get moving. I was shocked that this had happened as it was totally unnecessary. I was completely in control of the vehicle prior to the activation.

I’ve had the car for 7 months. Three (3) times the forward collision avoidance (fca) has engaged (full stop braking) when it was absolutely not necessary. All three times occurred while driving less than 30 mph on city side streets in houston, TX. On the first and third occasions there was a car in front of me but that car and my car were both slowing down as we approached a red light. My car suddenly slammed on the brakes; I did not hit the car in front nor was I hit from behind. On the second occasion, I was making a right turn and the fca slammed on the brakes and I was hit from behind. There was no damage to an older model car that hit me. My car had $785 in damage repairs. No insurance claim was filed. After incident #2 ( the one with damage) I adjusted the sensitivity of the fca to have a slower reaction. It didn’t help as I had a third incident. My make/model will not let me permanently disable the fca. After incident #3, I have been trying to remember to disable the fca each time I start the car. I have not reported this to the dealer. I will be bringing the car to the dealer next week for this issue. The date below is for the incident when I got hit.

The contact owns a 2025 Hyundai Tucson. The contact stated while driving 15 mph and depressing the brake pedal to decelerate, an unknown warning light was illuminated and a beeping sound was engaged. The contact stated that the vehicle failed to decelerate as intended and came to a sudden stop, causing another vehicle to crash into the rear of the vehicle. The air bags did not deploy. There was no injury sustained. The contact was able to drive the vehicle away from the scene. No police report was filed. There was no property damage. The vehicle was taken to the dealer, where it was test-driven, but the failure could not be duplicated. The dealer informed the contact that they had turned off all the sensors, except for the rearview camera sensors, to prevent the failure from reoccurring. The vehicle was diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 760.

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.  .

I am filing a complaint regarding a serious safety malfunction in my 2025 Hyundai Tucson’s forward collision sensor, which caused an accident. I have owned this vehicle for only two weeks, and I believe this issue poses a risk to myself and other drivers. On February 25, 2025, while driving, the car in front of me stopped and made a u-turn. There was no imminent risk of collision, yet my Tucson’s forward collision sensor erroneously activated and engaged the automatic braking system. This caused my vehicle to come to an abrupt stop, resulting in a rear-end collision. I have documented the incident, including photographs, a police report, and insurance documentation, which I can provide upon request. This malfunction is extremely concerning, as a feature designed to prevent accidents instead directly caused one. If this issue exists in other Hyundai Tucson vehicles, it presents a severe hazard for drivers. I urge NHTSA to investigate this as a potential safety defect, determine if other similar complaints exist, and assess whether Hyundai needs to issue a recall or software fix. I also need guidance on whether there are any known remedies or if I should take my vehicle to the dealership for inspection. This issue must be addressed before it leads to more accidents. Please let me know if further information is needed.

While driving on the highway at approximately 65 mph the car emergency brake kicked in with no cars in front of it. Causing a huge jerk. This happened 3 times within a 25 minute time span.

Regarding the forward collision warning. This system I feel is honestly scaring me and I am now turning it off whenever I start the car I was driving one day and a car abruptly stopped in front of me for a quick second but started rolling again rather quickly. I was slowing down, I saw the car stopping and before I could even react the car slammed on the breaks and completely locked the wheels up and I came sliding to a stop. It almost caused me to be rear ended which I am glad did not happen but again very close. I am also worried it may detect oncoming traffic and slam on the brakes I don’t like feeling that I’m not in control of the vehicle. This system in particular needs either disabled or looked over again.

All of the lights on the dashboard and check engines light were illuminated. The speedometer would not work and the stick shift would stick in park causing me to have to release the shift lock manually to drive. The failure mileage was 59,450.

Vehicle was parked for an hour facing south. When vehicle was started, forward safety and blind spot monitoring warnings came on and many other systems tied to forward camera were disengaged. Mileage: 123k. Power steering was unresponsive and brakes felt spongy. Disconnected battery and let sit for a day. Reconnected and issue went away. A week later, was parked at hospital facing south for 4 hours. Issue came back, this time disconnecting battery did not fix issue. Dealer currently has the vehicle and they are claiming it shows rear end damage even though the car hasn’t been in an accident since I was rear ended and car was repaired. Dealer reported over 80 body codes including blind spot monitoring radar.

It happened again. While traveling at highway speeds behind a slow poke, 2 cars passed me on either side at nearly the same time. This caused the auto braking system to activate, abruptly slowing my car for now reason. Luckily no one was tailgating me at the time. This is the 4th time the car has braked for no good reason on the highway (see previous reports) and the 2nd time when 2 cars passed on either side at the same time. This is clearly a software bug that needs to be fixed!.

While driving the vehicle suddenly started alarming indicating to check "forward collision warning" followed by an alert to check "lane keeping assistant. " immediately pulled off the road shut the vehicle off and checked the perimeter. No issues noted. Issue continues, while waiting for service from local dealers.

From the first day of purchase last June 2024, the front collision warning and avoidance system does not perform as advertised. If a vehicle cuts you off or you approach a vehicle too quickly the warning and braking do not intercede. I’ve taken the car to our local deal 3 times and they have found no trouble codes and say there is nothing they can do. I was also told by the service department manager “that they are all like that”. As a reference, we owned a 2019 kia sorrento for 140,000 miles and that collision avoidance system worked perfectly. I also contacted hyundia national service and they simply sent me back to the dealer. Lastly, I submitted a lemon law request that was rejected by hyundia.

In December, while parking in garage, the vehicle suddenly accelerated causing considerable property damage yesterday, Feb 26,2024 this happened again while parking. The car suddenly accelerated while parking, jumping over the parking curb and into the corner of a building causing major damage to the vehicle. No airbag deployment or forward collision warning in either case.

My truck keeps showing lights and is displaying that the crash collision is disabled.

The forward collision avoidance system made me have accident. I was driving on the expressway, the forward collision made the car stop abruptly, then accelerate. As I was veering to the right, the car stopped again in the middle of the expressway causing me to have an accident. This is unacceptable and very unsafe. This vehicle is not safe to drive with the collision warnings.

Forward collision alert came on and brakes initiated while I was behind a car that was turning into a driveway. The car in front of me was almost all the way into the driveway. After that I drove approximately 200 feet and the collision alert warning came on, no vehicles were around me. The next day, as I was driving, a car was waiting to exit an apartment driveway, the collision alert came on. No reason for it. I took my car in to Hyundai on January 9, to have the oil changed and check the forward collision alert system. They told me they checked it, and could not find anything wrong, and recalibrated the system, and hoped that took care of it.

The collision avoidance system has been going off randomly when there are no cars around, and also in the middle of traffic when I am more than two car lengths away from other cars; when I am on the highway driving fast and when I am on side streets driving slow, and even in my driveway. Additionally, some of the times that the warning system flashes and sounds off the car brakes and stops in the middle of the road. There is no pattern for when the incidents occur not are there any adverse road conditions. Roads here are flat and this has occurred during periods of no rain. Safety of myself my passengers and other driver is at risk due to the vehicle stopping for no reason. I took the car to the dealer, and they could not duplicate the problem and did not find any issues when checking the diagnostics.
