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

I lease a 2025 Hyundai Tucson SEL. This vehicle has experienced repeated electrical and safety system malfunctions. Display/infotainment failure: The center display has shut off while driving on at least 10-15 separate occasions. This has occurred while I was actively using CarPlay for navigation in an unfamiliar area, causing loss of directions while driving. Forward collision/automatic emergency braking (AEB) malfunction: The AEB system engaged unexpectedly and unpredictably while I was driving on the highway, causing the vehicle to brake suddenly. This resulted in another vehicle rear-ending me. This occurred while I was driving home from a doctor's appointment. I understand this vehicle/system was subject to a manufacturer recall related to this issue. AEB failure to engage when needed: On a separate occasion, while I was backing out of a parking spot, the emergency braking system did not engage or respond when needed, and I narrowly avoided being struck (T-boned) by another vehicle. Warning system malfunction after repair: Following the highway incident, I brought the vehicle to an authorized Hyundai dealer, who performed a front safety system software update. Approximately two days later, while driving on the highway, a dashboard warning appeared related to the front safety system. This warning disabled cruise control and other related features. Dealer inspection/dispute: I brought the vehicle back

I bought my car in for recalls and they performed service. I got down the road when the HUD started going out over bumps. They could not duplicate it when I bought it back after picking it up. This was yesterday 7/16/26. They have had this car for a total of 18 days not including other issues that I have bought it in for. Today I am having issues with the instrument cluster and HUD going out randomly over bumps still. This is exactly what I explained when dropping it for the repair. This is resulting in me not being able to read the instrument cluster since it displays no signal on cluster or goes completely black.

The rear door locks and trunk lid do not always unlock. This creates a safety concern for rear passengers because they cannot easily exit the car because door won't unlock. The dealership says issue is intermittent yet it's still happening.

I have had nothing but trouble with software issues since the very first recall (software related) on my vehicle, just a few months after I purchased it. I have had a very difficult time having Hyundai address these issues, and recently opened my third case with Hyundai. The issue: On 6/24/26 Peddar Hyundai conducted the software update for the recall regarding the front collision system. Later in the day on 6/24/26 and in the days following, whenever I turned on the car, Googlemaps would automatically pop up on the infotainment screen, the car’s navigation voice (not the googleMaps voice) would instruct me to turn right or left, etc. throughout the drive, despite no route being set. I have a video of this occurring. MOST CONCERNING: 6/25/26 I was pulling out of a parking lot, with no other cars or obstacles in my path, going slowly, and the automatic braking system ground the car to a stop. There was no warning on the dash. It took a few seconds before the car would allow me to accelerate. This is the very problem the software update was supposed to fix. 7/2/26 I was using GoogleMaps navigation at night and as I was driving, the infotainment system went blank and I had no navigation. After a minute or so the map came back on, but it was just spinning in circles and couldn’t right itself. Additional issues: the infotainment system randomly keeps popping up the question, asking if I want to open Google Maps. Sometimes when using the parking camera, an informational window keeps popping up stating “Press the button to display the camera view, or press and hold to activate the parking assist system”. I use this function every day, but for some reason, at times it keeps trying to teach me how to use it. (These types of glitches have happened before after software updates.) 6/26/26 I opened a case with Hyundai. Case number 42790134. I have yet to hear from them. I've called several times and they won't return my call or address this safety issue.

I was intending to make a left hand turn out of a dinner parking lot. As I approached the exit, I saw that a car was about to drive past me preventing me from making that turn, so I put my foot on the brake pedal to stop my car and let the vehicle safely pass in front of me. But the brake did not work. It did not stop my car. The pedal felt limp not firm I turned sharply to the left to avoid striking the other vehicle. Fortunately no other cars were coming in either direction. I put the car in neutral and then in park. Only by the grace of God a collision was averted. I then restarted the car, the brake pedal was now firm again and I drove home. I returned home and left the car in my driveway until Monday, July 13 when I had a tow truck take the vehicle to the dealer. This is not the first time my brakes became soft and limp and failed to stop my car. There have been at least two or three previous incidents over the the past months while backing out of a parking space, the brake pedal became limp. In those instances I was able to stop the vehicle by putting it in park. When I restarted the vehicle, the brake returned to being firm. These incidents are intermittent. I don't know when and where they will occur. To date, the dealer claims not to have found anything wrong with my brakes. Apparently, unless they can replicate my experience directly themselves, they intend to send me on my merry way. I don't consider the vehicle is safe to drive. The intermittent problems I have had with the brakes all occurred in exiting parking lots and not on the highway at 55 MPH - fortunately. These incidents occurred. The brakes have failed

I purchased a 2025 Hyundai Tucson in March of 2026. Shortly after the purchase the screen began to malfunction. The screen glitches continuously while driving and there is no way to turn it off. This creates a significant distraction and raises serious concerns about driver safety. Especially driving at night. The screen turns completely dark then all of a sudden comes back in super bright. Because of the glitching there is no way to get to the setting to possibly turn the brightness down. It also creates a loud noise for about 10 minutes then resets itself and start all over again. I notice there was a recall about the screens glitching previously and I reached out to Hyundai and they informed my VIN wasn’t apart of the recall so there was nothing that could be done. Because the vehicle is over 60K miles I am not able to use the factory warranty. I believe it is unreasonable for a vehicle that is only a 2025 model to experience a major electronic failure after such a short period of ownership. Regardless of warranty limitations, consumers should be able to expect that critical vehicle systems, particularly those affecting safe operation, will function properly. I respectfully request that Hyundai and/or the selling dealership review this matter and provide goodwill assistance by covering the diagnostic fee and repairing or replacing the defective infotainment screen. I believe this would be a fair resolution considering the age of the vehicle, the timing of the failure, and the potential safety implications. I have taken a few screenshots of the video I recorded to show what is happening. I am not able to upload the video so you can hear the loud noise it makes.

We have had two starburst cracks from very small rocks hitting our windshield on the highway and chips from tiny hail. I have never had a car with such a fragile windshield before. We are constantly worried that it would break easily while driving if something larger hits it.

The automatic emergency braking system activated early and aggressively causing a rear end collision. It is available for inspection upon request. While driving in busy traffic on a highway I was lightly braking to avoid sudden stops or unexpected movements of the vehicle while traveling between 20-30 mph. The vehicle then activated the emergency braking system and came to a sudden and unexpected complete stop. This sudden stoppage caused myself and my passenger to be thrown forward harshly against the seatbelts. Additionally I was unable to steer the vehicle towards the side of the road as the wheel had locked and avoid an SUV that was rapidly approaching my rear. This SUV subsequently rear ended me. The actual collision was minor thankfully due to the low speed of the traffic, but could have been much more severe if traffic conditions had been different. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. (I am in the process of this right now, but because my car was in a collision the dealer will not fix the recall or inspect the vehicle until the collision damage is fixed) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? See previous answer Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The vehicle had not exhibited any issues prior to this sudden stopping.

The head-up display and the digital display cluster turn off and on while driving. The digital display cluster seems to lose connection and will show a "NO SIGNAL" message. This will happen for minutes at a time. When this happens, the display is black and does not show speed or other important safety information. The vehicle has been inspected twice by the dealership; they are not able to replicate the issue. This problem began within weeks of purchasing the new vehicle.

Good morning the problems I am having with my 2025 are very discouraging. Started October of 2025, my tire light illuminated stated the tires were low when they are all at correct specs when using an air guage to check. November of 2025 while driving at night the headlights suddenly shut off briefly then came back back on. January of 2026 while leaving work the transmission would not shift, held accelerator pedal to floor but could not go above 20 mph all the way home for 3 miles. April of 2026 the right side of navigation screen went completely black, shut vehicle off twice and on third restart the screen reilluminated. June of 2026 same thing with the screen going black. I have had my Tuscon at the local dealer here in my town for supposedly a repair that they state was a "coaxel cable" behind the dash that was fixed that was causing this issue. I also had the recall performed for the front view camera software update but it is still showing not completed. This is very frustrating to be having experiencing these kind of issues on this new of a vehicle. Clearly something is going on with the software or something and the dealer keeps telling me they are not finding anything wrong. I am a service advisor myself at a small independent shop so I understand the terms they are using but something needs to be addressed to correct the issues that I am having. It is scary when driving and the screen goes black or driving at night and losing the headlight functions. I would appreciate if somebody will look into this and reach out to me to get some kind of remedy for why this is happening. I am paying alot for this vehicle and to say I am satisifed is an understatement. I have purchased Hyundai as my choice of vehicle due to the quality, great warranties and good reviews from other consumers however I am seriously thinking of exploring alternative makes as I do not want to keep going through this. Plus the engine consumes oil. I have attached p/w for review as well

I had the Hyundai recall 302 performed on 5/27/2026 and after the software update none of the front sensors worked. My wife had a 2 mph bump with the car in front of her on [XXX]and there was no warnings, also no damage no injuries that I'm aware of. So I started to investigate why there was no alarm sounded or any red warning light on the dashboard. Pulled the car into the garage and up to 6 inches from the garage wall no warning on the dash. Took the car back to the dealership on 6/5/2026 they changed some settings and it still failed to warn of an still failed. The gave me a service appointment on 6/9/2026 they calibrated the front windshield sensor and now the parking assist sensors worked. When I pulled into the garage the front camera showed yellow and red warnings as I approached the wall. That fixed the parking sensors issue. Still no forward collision avoidance warning shortly there after was referred to the service manager Rich Block he stated that the front bumper cover would need top be removed to calibrate the radar behind the bumper, but Hyundai's warranty would not cover it and, I should call Hyundai Customer care. I did and was contacted by Mohamed at National Consumer Affairs (714) 922 - 3276. and here we we sit. when they pulled the bumper they found the mounting bracket was bent. Mohamed at National Consumer Affairs (714) 922 - 3276 stated could I prove that all this happened after recall 302. I can only prove the parking sensor issue because after recalibration they worked. Hyundai Motors refuses to accept any responsibility for this incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving in a line of cars when there was a sudden slowing of all cars ahead of my 2025 Hyundai Tucson Hybrid. Car's Forward Collision Avoidance system applied brakes too early and too hard. Car behind me almost collided with my car's rear. My 2025 Hyundai Tucson Hybrid had less than 1,300 miles. I confirmed this early collision avoidance early braking incident to salesman, Stephan, on May 7, 2026 during service at Piazza Hyundai of West Chester. I explained it was a near collision by car behind me. No action taken by dealership, and no recall information was provided to me.

Sunroof exploded I was driving at high speed on a highway. sounded like a gun fired. glass must have flown back towards other cars. Noise was terrifying and I slowed to gain my composure before pulling to the side of the highway and calling the police. Car is currently at a local dealership. My initial thought was that something like a rock hit the sunroof, but on my own inspection it appears the explosion was outward. there is no evidence of something falling on it. no scratches on the inside roof cover which was closed at the time. No makes on the roof rack or scratches on the car roof. There was no warning of any kind from the vehicle that it might occur. after doing some research I discovered that there have been many cases of exploding sunroofs on Hyundai cars. Dealership is under the assumption that a rock hit the roof, but are not willing to give me a report of an examination into what might have caused it. They disregarded my conclusion that it exploded outward.

On XXX, my vehicle unexpectedly activated its automatic braking system while driving, resulting in a rear-end collision. My infant daughter was in the vehicle at the time. While we were fortunate to avoid catastrophic injuries, the incident placed both of us in significant danger and could easily have resulted in a much more serious outcome. The other driver may also have sustained injuries as a result of the collision. The vehicle sustained approximately $20,000 in damage. Since the accident, I have learned of Hyundai’s recall involving this braking system. Given the circumstances, I am deeply concerned that the condition addressed by the recall contributed to the collision. What is particularly troubling is that this was not the first time I raised concerns regarding the vehicle’s braking behavior. On February 23, 2026, at approximately 11:00 a.m., I spoke with my dealership, North Bay Hyundai in [XXX] regarding unexpected braking behavior that I was experiencing with the vehicle. My concerns were not escalated, and I was not advised that a potential safety issue might exist. Several months later, I was involved in a collision involving the same system that is now subject to recall. I am also deeply concerned by the manner in which this recall was communicated. I received only a text message regarding a defect involving a critical vehicle safety system. Given the potential consequences of unexpected braking events, I do not believe the seriousness of this issue was adequately conveyed to affected customers.

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.

My vehicle has an ongoing safety‑critical defect involving the braking system, powertrain, and ADAS logic. I have not driven the vehicle since 04/27/2026; all diagnostic trouble codes were recorded while the vehicle was in the dealership’s possession. On 05/05/2026, the vehicle stored multiple DTCs, including C164286, P071300, P076800, U060FF1, U060F29, and U061386. On 05/13/2026, P071300, P076800, U060FF1, U060F29, and U061386 were recorded again, showing repeated powertrain, communication, and control‑system faults while the vehicle remained with the dealer. On 05/22/2026, two additional safety‑related DTCs (P107600 and C272146) were first recorded, and both were last reported again on 05/27/2026, still while the vehicle was in dealer custody. These DTCs now show as Historical because the vehicle has not been operated since the last fault was recorded. Their Historical status only means the system has not run a new check — it does not mean the defect is repaired. The vehicle has also exhibited brake‑logic abnormalities, including a persistent Brake‑ON signal at highway speeds, which violates Brake‑Throttle Override safety logic and affects ADAS functions. The powertrain shows signs of torque converter instability, mechanical drag, abnormal slip, and heat buildup documented across these dates. Two OTA updates were performed during periods of instability, but neither corrected the defect. The dealership has not provided documentation confirming the safety issues were resolved. Because the braking logic, powertrain behavior, and repeated DTC activity remain unexplained and unresolved, I do not believe the vehicle is safe to operate.
