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

-The center display screen system failed. The screen intermittently glitches, strobes, freezes or goes completely black while the vehicle is in operation. This screen controls GPS/Navigation, backup camera display, vehicle settings and warning alerts. The vehicle and system are available for inspection upon request. -The failure creates a significant safety risk. When the screen blacks out or strobes, I lose access to navigation, backup camera visibility, vehicle alerts and system controls. The strobing/glitching is distracting and unsafe while driving, and the loss of display during driving and parking maneuvers increases the risk of collision or injury to myself, passengers, pedestrians and other vehicles. -Yes, the vehicle has been brought to an authorized Hyundai dealership 5 separate times for the same issue. This dealership has attempted repairs, replacements, and troubleshooting of the screen system but the problem continues to occur. -Yes. The vehicle has been inspected multiple times by authorized Hyundai dealership service departments acting on behalf of the manufacturer. Hyundai corporate has also been contacted regarding the unresolved defect. -The primary symptom is sudden screen malfunction without warning, including flickering, strobing, freezing or complete black out. There are no consistent warning lamps prior to failure. The issue first appeared in August 2025 and has continued intermittently since that time. No collision, accident, injury or property damage has occurred as a result of this malfunction.

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 dashboard and heads up display intermittently goes on and off. All warning lights are on when the dashboard comes back on. It goes off long enough to not know how fast you are going. Hyundai has this as a known issue for Limited trims of the Hyundai Tucson yet they only tell you to take it to the dealer for the vehicle to be fixed. Customers have taken their vehicle back to the dealership after the dealerships stated that the issue was fixed because the issue happens again a few days later. This is a safety issue that needs to be addressed.

Component that fails & available for inspection upon request? HVAC heat exchange and faulty gas gauge. I drive from Minneapolis to Warroad, MN frequently and the floor wells has insufficient heat hence impairing use and safety in Minnesota's severe climate. I have videos on the following but I am unable to upload videos to your site: (1) when I have heat on high, full blast and to foot well ONLY, the dashboard vent is 115-143 degrees (using a digital food thermometer) and a ~60 degree difference with the footwell at 65-85 (although 85 degrees sounds warm at 1 degree outside my feet are very cold - I would be happy to have you test this with me). (2) Brand new SUV consistently 1.5 - 3 hrs to warm up. I explained to Hyundai this is NOT a software issue rather an HVAC air exchange issue. (3) The gas gauge consistently underestimates the remaining fuel available by 50% in cold weather - an issue that between Bemidji, MN and Baudette, MN (102 miles/1hr 45min) there are few gas stations. On 11/11/2025 I took the SUV to first Bloomington Hyundai - they said it is working as designed. Then 11/20/2025 to Morries Hyundai said they are aware of a similar situation with the EON. However, without an "error code" Hyundai is unwilling to fix the air exchange. Additionally, I opened case#: XXX[XXX] -68 with Hyundai corporate - additionally they are unwilling to admit fault - this vehicle should NOT be sold in Minnesota's extreme climate conditions. How was your safety of others put at risk? If I run out of gas, my passengers and I risk frost bite or fatality of hypothermia. Has the problem been reproduced or confirmed by a dealer service center? Yes. Has the vehicle or component been inspected by the manufacturer? Yes. Were there any warning messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning messages have ever appeared.

I purchased the 2025 Hyundai Tuscon Limited in October this year. My conern is the headlights. When driving at night using the normal headlights, on the road on the left side shining there appears to be a black spot ahead of me. I've had asked front seat passenger if they noted it also to which they affirmed. I did asked my Hyundai Dealer about this and they stated that it is intended that way so that the oncoming vehicle is not blinded by my headlights. I'm driving on a 4 lane divide highway and it is very disracting to me as I feel I cannot see anything on the left side of the left lane when I am in the right lane. This is very distracting and they informed that it's that way on all of thier moderls

I am reporting a serious safety and reliability concern with my 2025 Hyundai Tucson. At only about 2,000 miles, I was informed by the Hyundai dealership that the transmission has already failed and needs to be replaced. This vehicle is essentially brand new and should not be experiencing a major powertrain failure so early in its lifespan. The transmission issue has caused significant concern regarding the safety of the vehicle. Sudden failure of a major drivetrain component creates an increased risk of loss of power, unpredictable drivability, and unsafe operation in traffic. This is especially concerning because this vehicle was already given to me as a replacement for a previous Hyundai Tucson that qualified under my state’s lemon law. A transmission failure at such a low mileage indicates a possible manufacturing defect or a systemic quality issue that could affect other consumers. I am requesting that NHTSA investigate this matter to determine if this is part of a broader problem in the 2025 Hyundai Tucson model line. This situation is unacceptable for a vehicle this new, and it raises serious concerns about long term safety and reliability. I am seeking further review and action so that other consumers are not placed in similar unsafe situations.

Bought car end of April brand new. June 25 brought in, console display went blank. Tried to start my car 11/10 and it would not recognize the key. Had to have it towed to dealership. Car battery was not dead, fob could start car, open doors, etc, but the car shut off as soon as you tried to start the car inside. Originally told fob problem. Nope. The told security control. Nope. Now being told it’s the BDC, basically the “control brain” of the car. Part is back ordered and my car is sitting parked at the dealership. It’s useless. Did some research and found that the BDC is becoming more and more common with a lot of people that have this car. It’s only 7 months old. No warning, dealer knows it won’t recognize fobs and not a fob problem. I was told, that the screen going blank in June was connected to this.

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.

Attention warning... If you wear glasses that transition to dark, the system shuts down the car on cruise control. Numerous warning lights and bells. Take a break warning and sounds continuously popping up on the screen. There is no way to disable the eyes forward attention system. You cannot wear sunglasses as it can't see your eyes. I use my cruise control all the time. But the system shuts it down. This happens on all 2025 Hyundai equipped with the attention system.

I started the car and put it in gear and it would not move. Then the check hybrid system and transmission warning showed up. This happened two times and I had to have the car towed in. The second time, it was determined that it is related to a recent recall for the Oil pump unit OPU Software. This recall is not listed any where and drivers are not being informed of it. Hyundai is not responding to my complaint.

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.

Instrument cluster screen and HUD go entirely blank intermittently, for various lengths of time. Loss of speedometer is a safety issue. Also, have no idea of what other functions may, or may not be working. Dealer acknowledges seeing and servicing this problem for other owners. And Hyundai owners online forum report the same issue. Dealer has replacement component ordered, but not 100% sure of cause or solution. No warning whatever. First occurred shortly after purchase in July 2025, with less than 1000 miles on it.

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.
