What 266 owners told NHTSA about the 2025 Hyundai Tucson Fuel Cell

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.

11/2/2025- The forward collision warning and the automatic emergency braking system engaged and brought my vehicle to a complete stop in the middle of the road when there was no imminent danger of a forward collision occurring. My vehicle was rear ended by the vehicle behind me as a result of the sudden and complete braking of my vehicle. This same incident happened a few days before this collision, but there was no vehicle behind my vehicle, so no rear end accident happened at that time. 12/1/2026- vehicle inspected at Jim Click Hyundai regarding the sudden stopping of the vehicle. Jim Click determined a fault code FRONT CAMERA BLOCKAGE. Dealer said they cleared the code and the problem should not return. On or around 12/8/2025 the 2025 Hyundai again had the front collision avoidance system randomly setting off alarms when the vehicle was driving on the freeway and other vehicles were traveling alongside the 2025 Hyundai. There was no emergency braking occurring at this time. 12/9/2025- the 2025 Hyundai returned to Jim Click Hyundai and at that time the dealer determined the front camera was showing an obstruction when none was there. They replaced the front camera with a new camera. 12/28/2025- the same problem of the front collision avoidance system and the automatic emergency braking engaged again, even though there was a new front camera installed on the vehicle. The 2025 Hyundai vehicle came to a complete stop in traffic. The vehicle ahead 2+ car lengths ahead swerved from the left lane to the right lane to avoid a box in the road. Driver of the 2025 Hyundai was applying the brakes when the 2025 Hyundai emergency braking system took over and the 2025 Hyundai came to a complete stop in traffic when there was no need for this. 1/2/26- 2025 Hyundai returned to Jim Click Hyundai and remains there while the Service dep't is driving the vehicle trying to diagnose the cause of the continued emergency braking problem.

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

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

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

customer of Hyundai 4 years now. issues with the Forward Collison-Avoidance Assist (FCA) on my 2025 Tuscan, malfunctioning, aggressively breaking, fantom breaking when absolutely no imminent collision will happen, causing other drivers to come within inches of a rear crash with me, also the same fantom breaking while parallel parking. the breaking causes me to be thrown towards my windshield. made appointment with a Hyundai service they inspected on a diagnostic machine and no recommended "codes" were available after test was done, no repairs made they said my car is fine. happened again within 2 blocks of service center PLEASE HELP

The 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 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.

This vehicle has had numerous problems since I leased it. To summarize, at times the vehicle randomly shifts out of the ECO mode, usually into the SNOW mode. The engine has also raced, hesitated, bucked, rattled and vibrated when trying to change gears. Sometimes, these actions are subtle and sometimes they are borderline violent. This happens more frequently when the engine is cold. Additionally, the AEB system has activated a number of times while in stop and go traffic, even though the vehicle in front was moving forward. On at least 3 of these occasions, i barely avoided being rear-ended by the vehicle following me. The final issue that I have noticed is a problem with the odometer. It has appeared to work normally most of the time, but I have noticed times where I didn't think the odometer accurately reflected the distance I had traveled. I was able to synch the odometer with the trip odometer on a local road that I was quite familiar with. The trip odometer registered 1.8 miles while the odometer only registered 1 mile traveled. All of these issues happened multiple times and are intermittent. I have had the vehicle to Hyundai dealers on 5 occasions, and they claim to have not been able to duplicate any of the problems that I have been consistently logging in to a "diary" that represents a list of when I have noticed these issues. I have been in constant contact with Hyundai, but they promised to send out a factory rep, then reneged, instead relying on the local service techs. Said techs had the vehicle for nearly 2 weeks, but only drove it for 16 miles (until I called AFTER a determination was made and they hurriedly drove it an additional 22 miles to give the appearance of a more complete exam), using less than a quarter tank of gas. To me, this wasn't a thorough exam and appeared to be a cover-up to avoid having to buy back the vehicle. Note: these problems have occurred on multiple occasions, therefore the date below is the lease date.

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.

NHTSA ODI 11706576

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.

Approximate date 10/7/2025. Driving 20mph clear daylight sunny conditions in right lane,another vehicle in left lane put on right blinker to merge in front of me into my lane. The merging vehicle was 3 car lengths ahead and had plenty of space to merge. Merging vehicle was only half way into right lane when without touching the brakes and no warning alarm the wheels locked up completely,skidding to a complete stop,almost got rear ended. 2 days later on 10/9/2025 same weather conditions while driving on highway the traffic was stop and go,speed 40mph. A vehicle ahead of me applied their brakes,no imminent threat, I placed my foot on brake pedal as a precaution,then brakes locked up so I pumped brakes thinking what else could I do? This did nothing,brakes remained locked until vehicle stopped. Almost got rear ended again. I can’t remember if any audible alarm or dash warning. These were the only 2 incidents with braking failure. Hyundai Dealer booked appointment but they could not find any issues with the braking system on 10/2025. Mechanic could not reproduce braking issue. When I picked up vehicle I spoke to the mechanic. He said “ if the braking issue occurs again please make another appointment. The salesman who I purchased the vehicle said “shut off the warning system”. Which I declined his offer. Thank you!

The Forward Attention Warning system performs erratically, frequently disabling the adaptive cruise control without warning. Even when it does emit a warning, which again, is erractic, the warning is barely audible. When conditions, such as grooved pavement or loud cabin noises, such as when a window or moonroof is open, the warning is completely in-audible. Similarly, the warning message displayed is not readable within the 0.5 - 1.0 sec (best estimate) that it is shown, as it is several lines of text - a distraction in itself. The disabling occurred during times when this ADAS feature is most value, cruising at highway speeds in heavier traffic - a time when automatic speed control and braking, along with maintaining a clear distance, are all invaluable to driver safety.

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

In October 2025, the center display screen in my 2025 Hyundai Tucson Hybrid began shutting off repeatedly while the vehicle was in motion. The screen controls essential functions including speed information, navigation, backup camera, safety alerts, and hybrid system data. When it shuts off, all of these features become unavailable without warning. The failure is intermittent and continues to reoccur. The component involved is the center display/infotainment system and may affect related radar and safety-system warnings. The dealer stated they duplicated the issue and reported that it was repaired, but the same display failure occurred again afterward while I was driving. The vehicle is currently with the dealer and is available for inspection upon request. My safety and the safety of others is put at risk because when the screen shuts off, I lose access to critical vehicle information. This has happened at highway speeds, including one instance where the display shut off approximately eight times within 20 minutes. In addition, the radar warning system has activated when no nearby vehicles were present, creating distraction and uncertainty. The problem has been reproduced by the dealership, documented by me on video, and reported to the manufacturer. The vehicle has been inspected multiple times by an authorized Hyundai service center and reviewed by the manufacturer’s customer service department. There have been no police or insurance inspections because the defect has not resulted in a crash, though the safety risk is significant. Warning symptoms include intermittent radar system alerts appearing without surrounding traffic. These symptoms began in October 2025 and have continued even after dealer repairs. The display failure persists and the vehicle remains unsafe to operate. P.S. I cannot upload video evidence as the website would not allow me and I have to start over.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at an undisclosed speed on three occasions and depressing the brake pedal, the Forward Collision Avoidance system malfunctioned. The contact stated that upon depressing the brake pedal, the Forward Collision Avoidance system activated the Automatic Emergency Braking system excessively, causing the brakes to engage forcefully, and almost caused a crash on one occasion. The dealer was not notified of the failure. No further information was available. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 2,000.

We were driving on I4 in stop and go traffic. Our speed was under 25 mph and we were over a full car length back from the vehicle in front of us. I was actively braking to come to a stop due to traffic and the forward collision / emergency braking kicked in and stopped us immediately. This caused a car behind us to almost hit us and cause an accident due to sudden stopping. This happened 3 separate times within a 30 minute timeframe with 2 different cars behind us. The system will take control of braking the car and the steering wheel, and will not always give it back immediately to be able to continue driving. This has occurred previously when slowing down due to someone turning in front of us just in every day driving, and has almost caused a wreck then as well. Our local Hyundai dealer said there was no recall or issue with the system. This is dangerous and going to cause an accident sooner or later.

NHTSA ODI 11700995

Forward collision alert system has slamed the breaks on for no reason. The vehicle begins abruptly stop for no reason. On two of the occasions I was almost rear-end by following vehicles. The system needs to be recalled.

NHTSA ODI 11700246

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

The front end collision avoidance “feature” slammed on my brakes so hard today, for zero reason. I was already braking, going less than 20mph and had plenty of room. This is NOT the first time, closer to double digits since I purchase in April. This time the car behind me narrowly avoided hitting me which was made worse as my vehicle takes too long to unlock and allow me to begin driving again. This is going to cause an accident and ruin my tires/brakes costing me money.

The FAWS Forward Assistance Warning System incorrectly identifies a "sleepy driver" and turns off Adaptive Cruise Control. FAWS has a dozen triggers that will cause this system to incorrectly alert the driver that his eyes aren't looking at the road and it turns off ACC. The FAWS has a turn off switch but it does not turn it off. So, without this safety feature of Adaptive Cruise Control, the driver just gets constant alerts to stay alert. Hyundai claims it is working "as designed" and has a suggestion to invest in specific sunglasses, or not be taller than 6'1" so the eyes can be detected, or don't wear a hat. Seriously, these are in the manual.

NHTSA ODI 11698814

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

Concern: DAW Driver Monitoring System False alerts shuts down cruise control. Safety issue when passing on interstate and suddenly the cruise shuts off and has to be reset. This warning sometimes goes off randomly and not due to driver attentiveness. If my arm is in top of steering wheel it blocks camera and wearing certain types of sunglasses. This system is asking the driver to not put his arm on top of wheel which is ridiculous.
