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 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.

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 contact owns a 2025 Hyundai Tucson. While the contact’s son was driving approximately 55 MPH on a three-lane highway, the brakes locked up. While attempting to move the vehicle to the shoulder, the driver lost control of the vehicle and struck the guardrail and rolled over several times. The air bags deployed, and the glass shattered. There were no injuries reported. A Police report was filed. The contact associated the failure with NHTSA Campaign Number: 26V316000 (Forward Collision Avoidance). The vehicle was towed from the scene to a tow lot. The local dealer was not contacted, and the vehicle was not diagnosed or repaired. The insurance company later towed the vehicle to the facility and deemed the vehicle a total loss. The manufacturer was notified of the issue; however, an assigned case manager had not responded. The approximate failure mileage was 19,081.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, another vehicle slowed down in front of the vehicle, and the Forward Collision Avoidance system activated, the brakes engaged, and caused another vehicle behind to crash into the rear of the contact’s vehicle. No warning lights were illuminated. A Police report was not filed. No injuries were sustained. Medical attention was not needed. The air bags did not deploy. The vehicle was taken to an independent mechanic, where it was diagnosed, and it was determined that the rear bumper, rear hatch, and several other unknown parts under the bumper needed to be replaced. The vehicle was repaired. The contact was notified that the VIN was included in NHTSA Campaign Number: 26V316000 (FORWARD COLLISION AVOIDANCE). The manufacturer was not notified of the failure. The failure mileage was approximately 18,120.

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.

NHTSA ODI 11746132

The contact owns a 2025 Hyundai Tucson. The contact stated that while reversing, the vehicle reversed 6-inches, and the Forward Collision Avoidance system erroneously engaged because there were two bikes mounted on the rear of the vehicle. The contact stated that the failure had been recurring consistently, requiring the driver to deactivate the Forward Collision Avoidance feature while reversing with the bikes mounted on the rear of the vehicle. The vehicle was taken to the dealer, where the contact was informed that there was no fix for the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and confirmed that there was no fix for the failure. The contact became aware that the VIN was included in NHTSA Campaign Number: 26V316000 (FORWARD COLLISION AVOIDANCE); and associated the failure with the recall. The failure mileage was approximately 500.

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.

NHTSA ODI 11740955

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.

NHTSA ODI 11740688

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.

MULTIPLE WARNING LIGHTS ON THE DASHBOARD, INCLUDING SRS , TCS, ABS , ALL LIGHTS STAY ON EVEN AFTER TURNING THE VEHICLE OFF. SYSTEMS DON'T WORK, SUCH AS LANE DEPARTURE, COLLISION AVOIDANCE & ABS DON'T WORK. SPOKE W/ KOEPPEL HYUNDAI, MENTIONED THE ISSUE, BUT WAS TOLD THAT THAT ISN'T PART OF THE RECALL, THEREFORE THEY WILL NOT ADRESS THE ISSUE. IT'S FRUSTRATING , DON'T FEEL SAFE DRIVING THE VEHICLE. WILL TAKE LEGAL ACTION IF ANY ACCIDENTS WILL HAPPEN DUE TO AN ISSUE THAT THE DEALER IS REFUSING THE ADRESS.

My car abruptly stopped due to the emergency braking system when the car in front of me braked (hard) but I had more than enough time to stop without having the emergency braking system engaged. Due to this, the car behind me hit me from behind damaging my bumper, trunk, and back lights

During the winter, my car would activate the forward collision warning and automatic emergency braking while I was driving when there were no other vehicles in front of me or even around me. It happened several times over a few day timespan, at the time I thought it was because I had gotten a car wash when it was colder weather and maybe the water had affected the system but now I see that there is a recall for this same issue.

NHTSA ODI 11740034

The forward collision automatic braking happens randomly and for no reason causing immediate and complete stops in the middle of traffic. It whips the head forward as if a crash had occurred and causes drivers to the rear to have to suddenly brake to avoid collision. Ive had it occur multiple times since purchase with the most recent being this morning in the middle of a roundabout. I know I can disable the system but 1) that's also a safety risk and 2) it turns back on every time I start the car which is unacceptable. Ive asked the dealership about it and was told that it cannot be disabled. I already have the sensitivity turned down as much as possible and it still is happening. This issue makes an otherwise wonderful vehicle almost uunrivaled. When this happens there's no warning before the sudden braking. It also will randomly just slow speed down for no reason and with no way for the driver to stop it. Something needs to be done. Fix the system and make available a way to disable it without it auto turning back on. Im fed up.

NHTSA ODI 11739244

Forward collision assist is dangerous. It engages when not necessary and has almost caused several wrecks by slamming on the brakes. There needs to be a way to permanently disable and not have to pick through a series of menus every time. Also, lately I feel like I’m fighting the lane keep assist when I’m on the highway, and it tries to move when not necessary.

NHTSA ODI 11739419

3 incidents of same braking component. Once while exiting a parking lot, the car slams breaks so hard while accelerating that car slams to hard stop with no warning. Once while driving through an intersection brakes engaged for no reason. Once after stopping at Red light, then when moving with traffic, car stops so hard with no warning that we were almost rear ended and seat belt left marks and bottom of car seemed to hit the ground. These violent automatic breaking events are scary because for no reason or cause and no warning the car suddenly hard brakes. Fear of being rear ended or car flipping from such sudden and hard breaking. This incident has not been inspected although the car is current on all maintenance and has been recently in to car dealer for oil change.

On 5/14/2026, while driving southbound on I-95 with my pregnant wife and young daughter, my 2025 Hyundai Tucson (approx. 7,500 miles, purchased new 10/2025) experienced multiple critical safety failures. Two days prior, the heads-up display (HUD) intermittently failed to activate. On 5/14, traveling at 65-70 mph near [XXX] , the brakes auto-applied without driver input. Simultaneously, the instrument cluster and HUD went completely black, eliminating all speed and vehicle status information. This recurred intermittently. Near [XXX] , the brakes auto-applied with full force, locking all four tires and bringing the vehicle from approx. 70 mph to a complete stop on the active interstate. Two trailing vehicles spun out and left the travel lane to avoid rear-ending us. A multi-car pileup was narrowly avoided. The vehicle was taken to Pearson Hyundai in Midlothian, VA. They diagnosed and replaced a faulty wiring harness. Immediately after the repair, driving northbound on I-95 back to [XXX] (5/16), the lane keep assist/lane departure system began pulling the steering wheel into the adjacent lane without driver input, repeatedly and unpredictably at highway speed. The dealer repair did not resolve the all defects. Within a three days this vehicle exhibited: (1) total instrument cluster/HUD failure, (2) uncommanded emergency braking at 70 mph causing two other vehicles to take evasive action (3) uncommanded steering input into an adjacent lane. These failures created immediate risk of serious injury or death. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There have been two instances now within about 4 months where my 2025 Hyundai Tucson's emergency braking/anti forward collision system has engaged completely unnecessarily, slamming on my brakes and almost causing the car behind me to hit me. In both cases there wasn't a car in front of me within at least 100 feet. In both cases I was going probably 30-40 miles per hour.

NHTSA ODI 11738046

The FCA engages in situations that are not dangerous. There is a slamming of the breaks which causes items in the car to fly off the seat and nearly cause the cars behind me to rear end the car. This is a dangerous situation and has happened about 6 times since we purchased the car less than six months ago. There is not a way to permanently disable this supposed safety feature.

NHTSA ODI 11736725

The forward emergency braking system on this vehicle is a hazard not a safety feature. I have almost been rear ended 3 times because of it and have had my neck and back hurt from the quick sudden stop! I was not even at risk of getting into an accident! This feature needs to be permanently disabled! I still owe 30 payments on this car but will be getting rid of it if i can't disable this permanently.

NHTSA ODI 11736762

What component or system failed or malfunctioned, and is it available for inspection upon request? Automatic braking system brakes for no reason when I am not near any cars traveling at high speed or even when I am already at a complete stop or moving very slowly but not anywhere near hitting the car in front of me. This has happened multiple times since I leased this car in July 2025 and it seems to be getting worse. I had a 45 min drive home today and it happened about 7 times all for no reason. How was your safety or the safety of others put at risk? It slams on the brakes unnecessarily and the cars behind me almost rear end me. This has happened on residential roads and highways. Has the problem been reproduced or confirmed by a dealer or independent service center? I just called to take it in. They seemed to have no idea what I was talking about. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? not yet but I am taking it in asap Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NONE

The cars speedometer screen and radio screen go black and sometimes flicker on and off. This makes it impossible to see the speed. Also the car stalls sometimes when this happens in traffic. The autonomous braking applies the brakes even when there is a large distance from other cars and objects to the point where it has almost caused me to get into an accident on numerous occasions. The driver attention alert comes on and off over and over again even though I’m fully focused on driving and well aware of what is going on and this sometimes happens in a sequence where all of the warning lights illuminate on dash. Sometimes all of the warning lights display on cluster after it goes black and then car says to shift to park when display goes back on causing safety concerns for me in traffic. In addition my sunroof glass is making a loud noise like it’s going to crack.
