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

As of today, March 17, 2026 , my 2025 Hyundai Tucson keeps having safety issues. On March 8th , 11th, 14th and 25th the car once again shut down mid-drive. This issue occurred last month as well but dealership claims no DTCs were found. I am noticing that the forward collision warning comes on without any cars or objects in front periodically since the purchase of my car. The light will remain on for a few seconds and disappear. The automatic brake system seems to be causing issues as well which I believe causes the car to shut off completely mid-drive. Once the car shuts off the panel lights turn on to include the engine light, but then after a few seconds I able to change gears back to park in order to turn car back on and continue driving. This has happened now several times since last month. However, I have had issues with my brand new vehicle since I purchased it last year. My car remained in the dealership for 3 months last year due to an engine, ac and power train issues. Prior to the car shutting off, No actual warning lights illuminate other than the forward collision warning light and the notification of headlights are turned off even though it’s daylight and headlights do not need to be turned on . Periodically and intermittently an alert about consider taking a coffee break alert has also popped up in the past. It seems Hyundai has a severe issue with the FCA operating system and over 100 complaints have been made about this vehicle nationwide and no recalls have been issued. I am afraid for my life and the life of others on the road as this car should not be stopping and shutting off while driving for no apparent reason.

WHILE TRYING TO PULL OUT OF DRIVEWAY IT WILL HARD STOP LIKE IM GOING TO HIT SOMETHING. I CAN BE DRIVING THRU TOWN AND ALL THE SUDDEN IT WILL TRY TO STOP ABRUPTLEY. IT DOES IT OFTEN. TOOK TO SHOP AND ALL THEY WOULD SAY IS ALL SYSTEMS WORK LIKE THEY ARE SUPPOSED TO. MY FONT COLLISION LIGHT COMES ON ALL THE TIME WITH SOME TIMES STAYING ON FOR A FEW DAYS. I HAVE TRIED TO WIPE IT OFF WITH NO LUCK KEEPING IT CLEAN. I DROVE IT OFF THE LOT TURNED AROUND ASND THEY HAD TO REPLACE A HEAD CAUSE IT STUCK OPEN. RUNS FUNNING.

After taking a left turn my car suddenly just stopped abruptly. There was a car behind me who just missed running into me.

I was driving inside a parking garage, making a right hand turn at a very slow speed (5 mph?), when my Hyundai Tucson Hybrid slammed on the breaks while in a right hand turn. There was a wall directly in front of me, perpendicular to the direction I was heading before I started to make my right hand turn. The wall was at least 15ft away. I was never at risk of hitting the wall. The breaks were applied after I was into the right hand turn. Most unusual, as I had the FCA (Forward Collision Avoidance) system turned OFF and I confirmed this by observing the symbol on my dashboard that indicated the FCA was off as soon as the breaks were applied. I don't understand how the car applied emergency braking going forward when the FCA was off.

I was driving on a clear day with no traffic in front of me, going approximately 35 miles an hour. My car abruptly took over the braking and suddenly stopped the car in the middle of the road. The cars coming from behind me had to swerve into the other lane to avoid a collision. It was terrifying. I contacted the dealer was told they had never heard of this happening and I probably had something stuck to the front of the camera. I said it wasn't the case and they said it was just an isolated incident and explained how I could disable the system each time I drive the Tucson if it made me feel better. There were no warning lights or other symptoms prior to this episode. They said I could bring it in and they could take it apart to look at it, but I would have to leave it for about 3 days, however they didn't think anything was wrong with it. Since they said they couldn't fix it, I didn't take it in and just disable it each time I get into the car.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at various speeds, the Forward Collision Avoidance warning light was illuminated for approximately 30-seconds to 4-minutes. Additionally, while driving in the daytime, the message “Headlights Off” was displayed. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The failure had occurred four times. The vehicle was not repaired. The manufacturer was made aware of the failure and suggested that the dealer contact an engineer to go to the residence to inspect the vehicle. The failure mileage was 3,940.

I rented this vehicle for 5 days. In those 5 days, twice while driving on the highway (at 5-10 mph under the posted speed limit due to heavy traffic, dry and clear weather), I found it necessary to brake hard due to other vehicle traffic braking hard in front of me. When I had slowed down sufficiently and felt I had sufficient space between my vehicle and the one in front of me, I let off the brake pedal, but the "forward safety" feature continued to brake until the vehicle came to a complete stop nearly causing the vehicle behind me to hit my vehicle. To be clear, no accident occurred, but in one of those instanced the vehicle behind me was within 1ft of hitting my rear bumper. Had the vehicle behind me not been able to stop in time, there would have been an accident, and because the brakes were locked by the computer, I could not have done anything to prevent it. After the second incident (on 2-15-2026), I looked through the vehicle setup information and found it is possible to disable the "forward safety" feature to prevent additional incidents, however, that setting can only be changed then the vehicle is stationary, and it automatically turns back on every time you start the vehicle.

The brake assist feature engaged when a second car cut a corner in front of me in Peoria AZ. The brakes engaged, and while waiting for the auto brake to release, a third care came up very fast behind me. I hit the gas in fear of being rear-ended. Apparently, in fear I simultaneously pulled on the steering column and the steering column pulled out beyond its normal range. The telescoping adjustment feature no longer works. The steering wheel is locked in a downward and elongated position. I took it to the local AZ Hyundai dealer for warranty repair and they said it was due to the Kirkland Hyundai dealerships failure to install a pin that locks the steering column in place after installing a lo-jack system. The column is not covered by warranty. There were no warning signs except the dangerous auto braking system, that caused a series of failures in the vehicle. This is the 4th time this braking system has almost caused a rear-end crash. The AZ Larry Miller Hyundai dealership suggested I contact the Kirkland Hyundai dealership in WA for damages. Damages to replace the steering column and replace the missing pin lock are nearly $3000.00 There are no pictures as the steering column has been reassembled but is bent and needs to be replaced.

The automatic braking that happens when the car sensor thinks you are too close to another car is dangerous. This has happened to me three different times when there were cars in front of me turning right. There was plenty of room and the car was turning so I was following, and it not only slams on the brake and makes you stop, but then it takes it a minute to reset before you can move again which then can slow traffic. I was almost rear ended two of these times. It is unsafe. You can manually turn it off, but you have to re set it every time you get in the car. I have seen many complaints about this occurring and causing people whiplash as well due to the sudden stopping on Hyundai sites.

Blindspot detection did not pick up car on my right side two times. Front collision warning is effected by the angle of the sun at certain times of the day. Dashboard dims randomly. Could be for a minute or much longer. Could dim on and off, or stay dimmed for over twenty minutes. Brought the car in twice for this problem. Claimed nothing found and tech reset the codes. Bought it in two weeks later, stating problem not fixed. Told them to check connection, suggested they might want to replace the cables, and its a known problem. Again, reset the codes. Only this time they fiddled with the dimmer control on the console and I can no longer adjust the setting.

The adaptive cruise control reduces speed when the car's driver camera "senses" that driver is distracted when in fact, this occurs frequently within even a 30 minute drive: it senses "distracted driving" due to wearing sunglasses, short stature making in cab camera have difficulty seeing eyes of driver, etc. This is a frequent problem in my car and a frequent problem in driver forums. This is unsafe when it slows car without warning and is stressful. Upgrades needed for safety.

Component or system that failed or malfunctioned: The electronic throttle control system and/or the powertrain control system malfunctioned, causing the vehicle to accelerate automatically and involuntarily. How safety was put at risk: The malfunction caused a collision with another vehicle and a structure. The failure placed the safety and physical integrity of two individuals at serious risk. Problem reproduction or confirmation: To my understanding, the issue has not yet been reproduced or confirmed by a dealer or an independent service center. Inspection of the vehicle or component: The vehicle and/or the affected component have not yet been inspected by the manufacturer (Hyundai), law enforcement, or insurance representatives, as an insurance claim is currently in progress. Warning lamps or prior symptoms: There were no warning lights, messages, or other symptoms prior to the failure. The incident occurred suddenly without any prior indication. During the event, the brake pedal did not respond.

I was following another car on an urban main street. We were approacing a red light, we were both slowing down and my Tucson Hybrid slammed on the brakes unexpectedly when we were close to the stop the stop light. There was no risk of me hitting the car in front of me. Fortunately, there was no car behind me.

I was travelling southbound on a main urban street. I was approaching an interesting with a feeder road to a major freeway. I was in a line of cars making a right hand turn onto this feeder. Just before I was about to start turning right, the Tucson Hybrid suddenly and unexpectedly smalled on the brakes and I came to a full stop. I was HIT FROM BEHIND. There was minimal damage to the car that hit me. My car had damage to some plastic components on the bottom of my rear bumper. Total cost to repair this damage was 785. No insurance claim was filed.

Driving south on a busy 4 lane divided city street, as I approaching an interestion I initiated a right had turn with about 1 car length gap in front of me. I was driving about 5 mph. The car suddently applied the brakes to a full stop. The car behind was able to stop in time and not hit me. There was no risk of me hitting the car in front of me.

I was exiting a freeway a unusually slow speed as it was very congested, making a right hand exit. While I was in the curve of the exit ramp, the car suddently applied the brakes to a full stop. There was a car in front of me but we were going the same speed. Fortunately, the car behind me was able to stop in time and not hit me. There was no risk of me hitting the car in front of me.

I was driving straight in the left most lane on an expressway, about to make a left turn on a green left turn arrow. The vehicle in front of me was making a U-turn. My Hyundai Tucson abruptly braked quite hard. I'm not sure what caused it but I'm guessing the vehicle making U-turn slowed down a bit before the U-turn and might have triggered a forward collision avoidance braking but I didn't feel like there was a need. This caused the vehicle right behind me to also abruptly brake and if they hadn't, they might have rear-ended my car. After making the left turn, the vehicle behind me angrily overtook me because they likely didn't know it was the car's system which did this

The forward collision avoidance system in this generation of Hyundai tucsons is dangerously flawed. We previously had a 2020 and no issues, but this one slams the brakes at the drop of a hat and has nearly caused several accidents as there is no good reason for the intervention (ample space to leading vehicle) and it brakes so hard that cars behind typically need to veer to avoid rear end collision. This is not a one-off event or linked to particular driver/driving style - both adult owners of this vehicle have experienced this on multiple unrelated occasions. All sensitivity setting have been set to minimum and the only way to drive with peace of mind is to completely disable the system - but here is where the next massive design flaw is: the system automatically reenables at each re-ignition; there is not permanent override, which is EXTREMELY dangerous. It is not practical to manually disable the system on each drive because you need to navigate multiple system menus to adjust the setting. Google and user forums confirm this collision avoidance system is a widely experienced and complained about safety issue for Hyundai and it should be investigated. People will likely get killed due to this “safety feature”. Ideally Hyundai should push a recalibration for those who want this feature AND enable a permanent override option in the system settings for those who don’t.

The contact rented a 2025 Hyundai Tucson. The contact stated that the vehicle would stop and would restart independently while driving. The contact stated that while attempting to reverse, the vehicle failed to respond on several occasions while the gear shifter was in reverse(R). The contact stated that the failure occurred while there was a vehicle parked behind the vehicle or further away. There was no warning light illuminated. The rental company was informed of the failure. Additionally, the contact stated that upon shifting to reverse on one occasion, the vehicle responded, but unintendedly accelerated. The contact stated that upon depressing the brake pedal, the brake pedal was stiff and failed to respond, causing the vehicle to crash into an unoccupied parked vehicle. The contact stated that the distance between the two vehicles could fit two parked vehicles. The contact stated that her teenager was occupying the front passenger's side seat during the incident. The contact stated that the front passenger's side and driver's side seat belts failed to restrain the passengers as needed, causing both passengers to use their arms to protect themselves. The police officers arrived at the scene but did not file a report. Both passengers sustained arm, neck, and head pain but declined to be transported to the hospital by ambulance. The contact stated that the gear shifter was locked after the crash and required two hands to move to park(P). The rental company was informed of the failure. The contact was able to drive the vehicle back to the residence. The vehicle was driven to the Rental Company the following day. No further information was available. The dealer and the manufacturer were not notified of the failure. The failure mileage was 24,292.

The contact owns a 2025 Hyundai Tucson. The contact stated that while his wife was driving at various speeds, the imminent crash braking failed to function as intended. The first time that the failure occurred, the contact's wife was driving in the rain, and a beeping sound was coming from the vehicle, and the vehicle stopped independently. The vehicle returned to normal functionality after several minutes. The contact stated that on a separate occasion, while his wife was driving in slow traffic, there was an abnormal beeping sound coming from the vehicle before the vehicle independently stopped. No warning lights were illuminated. The vehicle returned to normal functionality minutes later; however, the failure persisted. The vehicle was not taken to the dealer or an independent mechanic, and the vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 1,000.

I’ve been driving this car for nearly a year, and during that time I’ve had multiple incidents where the Forward Collision-Avoidance system applied sudden hard braking when it wasn’t necessary, creating dangerous situations. I don't think I will be fortunate every time. I believe there is a serious issue with how the Hyundai's FCA system is operating and it needs to be investigated as a priority. Currently I am driving with it turned off every time I start the car. On my research I found this issue has been reported by multiple other drivers as well and I don't see any acknowledgement or reference from Hyundai on this so far.

engine RPMs surged and the car accelerated forward without foot on the gas pedal concerned about possible pedestrian accident or collision with objects and prop. damage. dealer was unable to duplicate the problem and no repair was made there is no warning...I never know when it will happen and it has occurred in a number of different circumstances

NHTSA ODI 11713291

Hard braking first occurred on a major highway with no prior notice that this would happen in close call accidents. The cars traffic had to veer away from me in order to avoid hitting me. Another highway (95) incident was a 18 wheel semi that had to move to the shoulder and could have easily totaled my car and me. I then researched this and found I could delay the action be setting the Forward Collision-Avoidance Assist mode to "Late". This helped in giving notice for some time, however the hard braking occurred again on a regular two lane small highway as I switched lanes, saw a car stopping suddenly and the brakes locked up. (This is the latest incident as dated below). There was no "Late" warning, the brakes just locked up. Being in fear of my and my families life I did further research and found that I could disable "brake assist" and only get warnings - which is what should be the default - BUT, this must be done each time I start the car. If my wife drives and forgets to do this each time I now fear for her life!!! This is not a simple matter. It is unconscionable and horrible this type of control over basic transportation is allowed to exist. This must be addressed and corrected! I'm all in on helping make meaningful change to this issue.

NHTSA ODI 11712915

The forward collision avoidance engaged when it was unnecessary and nearly caused me to be rear ended. It doesn't slow you down, it brings your vehicle to a complete stop and leaves you stuck unable to move for a few seconds... just long enough for the person behind you to read end you. This is incredibly dangerous. I would speculate that this feature will result in many rear end wrecks and should be addressed expediently or Hyundai may risk a significant class action lawsuit.
