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

The Forward Collision-Avoidance Assist (FCA) is braking aggressively without a valid hazard, creating a serious rear-end collision risk. Incident 1 [XXX] , approx. 60 mph) : A vehicle legally changed into my lane with safe separation. The FCA system detected this as a collision risk and applied hard braking on the freeway. Following traffic had to brake abruptly and I narrowly avoided being rear-ended. Incident 2 (Intersection U-turn, 15 mph): While completing a permitted U-turn on a green light, the FCA detected a distant cross-traffic vehicle and suddenly braked in the intersection, leaving me stopped in an unsafe position. I set FCA sensitivity to the minimum/“Late” setting after the first event. The false hard-braking continues. Hyundai dealership [Anaheim Hyundai] states “no issue found.” This behavior is repeatable and unsafe. I request investigation into false positives and unintended hard braking, a software remedy, and guidance to disable automatic braking until fixed (warning-only) if permitted by Hyundai.Currently even if it is disabled it resets after the SUV is turned OFF. I realized there are multiple threads on reddit on the same issue for Tuscon 2025 models with some of them resulting in accidents.

FCA system slammed brakes all the way to a complete stop in middle of traffic for no reason. Car in front was slowing down, and I was already braking at more than a safe distance. This is completely unacceptable and extremely dangerous. There needs to be a way to permanently disable this overkill feature that creates way worse problems than it is supposed to solve. There are numerous complaints about this issue from other owners of this model, please help!

I was driving on the road this morning approx. 25 mph (clear road, no rain, snow etc.) The car came to a full abrupt stop. Collusion/warning notification never came on (there was nothing in front of me) seatbelt locked. Car would not move. I put the car in park and had to turn the car off and back on to get the car to move. This honestly scared the life out of me. I had several cars behind me that could of rear ended my car and caused serious harm to myself or other drivers. I called the dealership (will be dropping off this evening) but they made it very clear that if they can not duplicate the problem there is nothing that they can do. The car has 8,000 miles on it and was purchased in April 2025.

Multiple times my vehicle has come to a complete stop unwarranted. There have been multiple instances of the automatic braking triggering on Michigan left hand turns with no traffic oncoming. This was reported to the dealer and they found no issue, however it has happened again since. The vehicle has also multiple times come to a full stop in heavy traffic when I was already braking and a full stop was unnecessary. There were two instances from this where I was very nearly rear ended, including on the expressway. There were no warnings that the system was malfunctioning.

While driving at speed in heavy traffic, I quickly merged from the right lane to the left lane to avoid an obstacle. My vehicle and the new vehicle in front of me (in the left lane) were traveling at approximately the same speed, although there was an admittedly small (one half car length) distance between us. My forward collision assist inaccurately identified this new vehicle in front of me as a sudden danger that I was going to hit. It immediately applied full braking power and played the forward collision alert sound. This aggressive and unexpected stop spilled and broke items in my car as they slid, roughly strained me against my seat belt, and caused the vehicle behind me to aggressively brake. A rear end collision was narrowly avoided, only due to the fast reaction of the driver behind me. This aggressive and dangerous forward assist and emergency braking can only be temporarily disabled for one drive, and resets every time the vehicle is turned on. I have not had my vehicle inspected for this issue, but communities on the internet have confirmed that this is a common problem.

While driving a 2025 Hyundai Tucson rental vehicle (VIN: [XXX] ), I experienced a sudden and unintended acceleration, and the steering appeared to turn without input.The vehicle veered off the road and struck a tree on a local street two blocks from my residence. The result was the wheel was popped off of it's axel and deflated immediately. Two days prior, I experienced a similar event in the same vehicle — sudden acceleration and braking hard making a loud braking noise. I suspect a mechanical or electronic malfunction. No warning or sensors were alerting me that this would happen. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Many 2025 Hyundai Tucson owners have reported significant issues with the driver attention warning feature, particularly when using cruise control and wearing sunglasses, leading to safety concerns and frustration. Common Complaints Constant Alerts: Many drivers have experienced the driver attention warning activating unnecessarily, especially while using cruise control. Users report that the system beeps and prompts them to keep their eyes on the road, even when they are attentive and looking straight ahead. This has led to frustration, with some considering disabling the feature entirely. 2 Sunglasses Interference: A recurring issue is that the driver attention warning system struggles to detect the driver's eyes when sunglasses are worn. This has caused the system to issue warnings and disable cruise control, which can be particularly dangerous in heavy traffic situations. Drivers have noted that even moderately tinted sunglasses can trigger these alerts, making it difficult to use the vehicle comfortably. 2 Safety Concerns: Some users have reported alarming incidents where the driver attention warning system caused abrupt braking, leading to near-collisions. For instance, one driver described a situation where the system suddenly applied the brakes while driving between vehicles, creating a hazardous situation. This has raised serious safety concerns among owners, particularly regarding the system's reliability and responsiveness. 1 Lack of Support from Hyundai: Many drivers have expressed dissatisfaction with Hyundai's response to these issues. Complaints about the driver attention warning feature have been met with minimal support, and some users feel that their concerns are not being adequately addressed by the manufacturer. 2 3 Sources Summary of Issues Overall, the driver attention warning feature in the 2025 Hyundai Tucson has been a source of frustration and concern for many owners. The combination of false alerts, interference from sunglasses.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving 55 MPH, the contact attempted to switch lanes, and the Forward Collision Avoidance feature intermittently activated, bringing the vehicle to a complete stop. The contact started to experience neck pain from the consistency of the failure, but did not seek medical attention. The failure had occurred on several different occasions. No warning lights were illuminated. The vehicle was taken to a dealer, where it was diagnosed that the vehicle was performing as designed. The vehicle was not repaired. The contact stated that she was concerned that the brakes would sustain damage over time due to the constant failures. The manufacturer was notified of the failure and stated that if the contact permanently disabled the Forward Collision Avoidance feature, the warranty would be affected. The failure mileage was approximately 8.

The car breaks itself so abruptly when there is no real danger. This has almost caused for me to be rear ended on multiple occasions. Especially scary on the freeway. The forward collision warning is set to "late," and it still causes a huge jolt.

I have taken the vehicle to dealer every month since purchase . The light for the forward collision inside the RPM dial continues to come on as I driving . I have made several attempts with the dealer to fix this matter. The vehicle is new . It now has 13,696 miles on it now since purchase. I have a case with HYUNDAI of America . I left my vehicle with the dealer for a month of this time and I got my vehicle back , it had grey seats instead of black. My tires were different as there are rotated burn marks on the exterior of them . Something is wrong here . I am inheriting a problem that is not safe while driving . My understanding from reading about the forward collision light is deactivating while driving . How is this safe for the driver and occupants or others on the road .

I was traveling on [XXX] in Nashville. There was a motorcycle speed trap on the right shoulder so I moved over to the left. The car in front of me also moved to the left and my car slammed on the brakes and came to a complete stop on the highway. I was badly rear-ended causing $12,500 in damage. This has happened 2 other times to me since then. This seems to be a consistent problem with the 2025 Hyundai Tucson. I'm fixing my car and selling it as I don't feel safe.

The vehicle will continuously pop up the notification “Consider Taking A Break” while driving at highway speeds when using the adaptive cruise control. When this occurs it emits 6-7 audible beeps that distract the driver from the wrong and to look towards the instrument cluster. It was also turn down the infotainment system as well. This feature is unable to be turned off in the settings z it has continuously distracted my driving and made it more unsafe while driving at highway speeds. It makes the adaptive cruise control not worth using which is more harmful for a driver to continually have to accelerate and decelerate.

There is a camera mounted on the steering column that is "supposed" to be a safety feature to tell you when you are not paying attention to the road. It gives you a picture of a coffee cup and says "consider taking a break" along with repetitive beeping. Unfortunately, if you wear sunglasses (mine are prescription), a hat, are too short or too tall it can go off repeatedly. It is extremely distracting and causes you to take your eyes off the road to see what's going on. On a 350 mile trip that I make often, it has gone off for a solid hour every 4 minutes! It averages about 30-40 times in that 5 1/2 hour trip. It also mutes anything that is playing through the infotainment system including directions. I have asked the dealer who says there is nothing they can do and it is a known problem. Hyundai says it is functioning as designed. I have also filed a report with Hyundai. A safety feature that causes distractions is not a safety feature! Also, the emergency braking has almost caused me to get rear ended on a number of occasions. I have been in the process of slowing down or braking when the emergency system kicks in and almost throws me through the windshield. Cars following at a reasonable distance have to slam on their brakes to avoid hitting me. Isn't this feature supposed to help you avoid accidents, not cause them

In my 2024 Tuscon, Hyundai has connected their cruise control to their driver assistance function. This system includes a camera on the steering column that watches the drivers eyes. If for any reason, they cannot see your eyes they will shutdown cruise control without warning. This can be caused by simply wearing sun glasses. So this forces the customer to choose between two safety features. Cruise control which we all know has signifcant safety implications reducing stress fatique, etc. and bypass all the driver assistance systems. There are people who are putting black tape over the camera and disabling DAS so they can use their cruise control due to the inability to wear sun glasses when heading west (obviously even within a curve, so it shuts down unexectedly in the curve). Surely that is not an acceptable solution. Hyundai should add an option to ignore the eye checks while using the cruise control but so far they have totally ignored it. You can google for "Hyundai cruise control sunglasses" and will see a lot of complaints and people disabling safety features. Obviously there is no specific event, this is happening all the time in the US.

The following problems began 5 months ago, 8 months after purchase with about 4770 mileage and current mileage of about 7623: Multiple occurrences of Check Engine light coming on, sometimes setting DTC code, but often not setting code. Multiple occurrences of Crash Warning light coming on; It may have set a code or codes, but usually not. I think neither dealer was able to reproduce these 2 intermittent problems. Engine light, so far, has not occurred since it was traced to faulty connectors. As far as I know, the Crash Warning light has not come on since the dealer reduced front camera sensitivity. Also, for the past 5 months there has been intermittent, engine miss, skipping or cut-out. As of this writing it still occurs while driving and will lurch or buck if it happens under acceleration This is not frequent, but it happens erratically and it may happen only once or a few times in one day or several days between. This has not set a DTC code as far as I know; I think the following may be related to the skipping. Once, while coming to a stop, the engine stopped or almost stopped; it bucked when it happened, but continued to run. All warning lights came on for a second or two, then went off, except 3 warning lights and the warning triangle. Although the engine was running, the tachometer and speedometer read Zero. The engine bucked as I slowly drove into a parking lot, then I restarted the engine; it seemed ok, then. About 3 weeks later, while driving at slow speed, just as I took my foot off the brake and was about to accelerate, the engine quit. When the engine quit, the audible Crash Alarm went off with a message saying the engine was not running, press the start button. I started the engine, it did not have normal power. I stopped, restarted the engine and it seemed ok. I have been to the dealer several times because of these problems; dealer is still troubleshooting the last incident. This could cause an accident, especially if it occurs at a higher speed.

I was driving on a highway in the largest city in the world and while vehicle merging into my vehicle, Hyundai Tucson automatically and abruptly engaged emergency forward collision. There was absolutely not necessary. All loose items in vehicle went flying inside of my car. My body went forward as well as my passengers. Luckily I was not rear ended in an accident. This is the third incident of the vehicle automatically engaging safety features which actually does the opposite and is a hazard, since I bought the car in Feb 2025. There is no way to permanently disable these features. A driver not being in control of their car is a huge liability on the road. This vehicle must be recalled to disable this feature. Perhaps in a rural area somewhere in the world with no other cars around , this wouldn’t be an issue. Large cities with vehicular and pedestrian traffic it is a danger.

Under two occasions I was driving on the highway at a safe distance from the car in front of me and my car emergency braking system triggered and went off and caused my car to stop in the middle of the highway. This caused a collision behind me. There was no reason on either occasion for the braking to bring the car to a hault.

Control screen keeps going randomly blank, for different periods of time, putting the driver at risk, because the vehicle information, including speed, lights, wipers, basically everything is displayed in this screen. Sometimes the sentence NO SIGNAL shows up. I had experienced several scary situations, specially in freeways when raining, you have zero driving information. The car has been to the dealership service 4 times, with different tentatives of repair, none of which worked. The last time my car was at the dealership service for 25 days and after 2 days the problem was back, even worse. Sometimes all the lights of the control screen light up, with no reason and keep on even after the car is turned off. This is our only car and we need it, but the car is absolutely unsafe and unreliable. I refuse to leave the car for a 5th time, Hyundai has no idea what the issue is and obviously cannot fix it. The lane assist is also malfunctioning, sometimes the warning system doesn’t work properly. Twice the car emergency brakes stopped the car abruptly without a reason to do so (no risk of collision, no car or object in front ). One of those times the car behind me almost hit me, because the stop was abrupt and for no reason. I have many videos and pictures, but apparently I cannot upload the videos in this form. I have the paperwork, but Hyundai refused to refund for the vehicle. I highly recommend an investigation, Hyundai is getting away with a very serious problem and someone will get hurt as a result of these issues. Thank you for the attention.

9/26/25. Friday late afternoon at 5PM. Driving on the Southern State Parkway in stop and go traffic…. the traffic opens up and we start driving to about 10 MPH, with no emergency present and the car did an emergency stop on it’s own. Frightening experience…it’s amazing we didn’t get rear-ended. This is the third time this happened, but I only documented this time.

At least 5 times now when no car was breaking extremely close to me or when I gently touched the breaks the automatic emergency breaking kicked in and slammed the car to a stop. Twice the car behind me had to swerve out of the way and hit another car causing 2 accidents without my car being involved. Once it caused me to hit my head on the steering wheel. This function is more destructive and dangerous than helpful. At no time should my car go from 70 to 0 in a second for no reason, but with this it does. Got the car in the March 2025 so 5 times in 7 months.

2025 Hyundai Tucson SEL Convenience The car is equipped with FAW Forward Attention Warning System which is supposed to give a warning if the driver's focus is diverted from looking at the road. The problem is that while driving in what Hyundai calls HDA (Highway Driving Assist) which activates when the car is placed in adaptive cruise control (cruise control that keeps the vehicle at a set speed and distance from the cars ahead) and lane driving assist (driving assist to keep the vehicle centered in the lane) the car issues far too many false warnings telling the driver to "keep your eyes on the road". While in HDA, the car monitors the driver's eyes and head position using a driver facing camera, part of the FAW (Forward Attention Warning system) or DDMS (Direct Driver Monitoring System) to assure the driver is focused on the road ahead. However, in the 2025 Hyundai, this system is so flawed that the car is practically undrivable in the HDA mode with cruise control and lane driving assist engaged issuing too many false warnings, that the driver is not focusing on the road. The multiple warnings, in some cases every few seconds, is extremely distracting taking the driver's attention away from safely controlling the vehicle. The system which is intended to make the vehicle safer is instead such a distraction it makes the car unsafe due to the constant false warnings requiring driver attention to address them and away from safely operating the vehicle.

This vehicle is a pile of hot garbage. Front end collision system slams on the brakes when you are not even close to hitting something in front of you plus it will auto brake randomly but often. I was backing into a parking spot and someone walked in front of the car and it slammed on the brakes. Dealer says only way to fix this is to turn the entire safety system off. The coffee break warning has zero rhyme or reason and will go off 10+ times in a trip even though I am not distracted and use my turn signal changing lanes. Dealer states there is no way to turn this off. Dashboard randomly flashes and goes dark along with all lighting in and outside the vehicle. Dealer was unable to duplicate the problem and returned the car with no fix. Drove the car in the rain for the first time and dashboard came up with a ton of errors and crash detection turned off. This is new and will be taking the car in for this and is now the reason I am filing another complaint. This vehicle is NOT safe and can be very scary to drive because you don't know when it will just take over for you.

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.
