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

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!

On numerous occasions (over 20) the forward collision system just slams on the brakes to a full stop, there was nothing close enough to vehicle to cause this issue. Sometimes it’s caused by rain or wind, sometimes for no apparent reasons. One time it caused a no damage accident as person behind me tapped my bumper. In traffic it is set off often with nothing within a safe distance away. There was no obstacles or sudden movements from other vehicles around me. I have brought the car back too Hyundai 3 times only to tell me either a dumb excuse or nothing is wrong with vehicle. I have seen on forums there are a lot of incidents with this particular car We have serviced the vehichle 3 different times over this issue and were told there is nothing wrong with the vehicle Accident happened in summer so I will say there was a crash in additional details but last date occurrence of automatic stop was this morning

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)

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.

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.

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.

Forward collision warning automatic braking caused car behind me to rear-end me. This is the first accident but third time the automatic braking unnecessarily caused an issue. The car in front of me was far enough away that it did not require an auto-brake.

My Tucson was involved in a MVA. I was hit in the rear end by another SUV on the rear back passenger side of the vehicle. During impact, the steering wheel literally detached from the dashboard in my driver's hands leaving us with no way to steer or maneuver the vehicle. The result of this safety failure could have lead to serious injury or death of myself, my driver or anybody in the path of the vehicle. We did have hit anything. There is zero front or side damage to the Tucson. No airbags deployed, not even the one in the steering wheel. There were no warning lights or anything indicating there was a problem w the vehicle. I called the dealership and filed a complaint with Hyundai consumer affairs. They had an inspector go inspect the vehicle and followed up w a letter stating the vehicle did as it was designed to. The vehicle was deemed a total loss from my insurance company. It is currently sitting in impound and unsure if it is available for future inspection. There was zero issues with the vehicle prior to this incident other than a stone chip to the windshield that was due to be replaced. This vehicle was only 5 months old.

On 08/31/2025, I was involved in an accident while driving my 2025 Hyundai Tucson. While attempting to change lanes at highway speed, the driver behind me failed to see my turn signal and collided with my vehicle. I believe the cause was the unusually low placement of the rear bumper-mounted turn signals, which creates a direct visibility flaw. The Tucson’s turn signals are mounted low on the rear bumper instead of at eye level within the taillight assembly. This design makes them especially difficult to see in two critical conditions: Bright Sunlight: The low-mounted signals are easily washed out in daytime conditions, reducing visibility to following drivers. Low Light/Traffic Conditions: At night or in heavy traffic, larger vehicles and brake light glare further obscure the signals. In my case, the driver behind me could not see my intent to switch lanes, and despite my efforts to avoid a collision, the lack of visible signaling directly led to a frontal driver’s side impact. This design presents an ongoing highway safety hazard: Poor Visibility: Low placement reduces signal recognition in both bright and low light. Accident Risk: My collision demonstrates the real-world consequences of this flaw. Durability Concerns: Bumper-level placement exposes wiring to water, debris, and road wear, raising the risk of malfunction. Although the accident resulted in minor damage, the potential for severe outcomes at highway speeds is significant. I respectfully request NHTSA to investigate this design flaw and evaluate whether corrective action (recall, retrofit, or advisory) is warranted. UNKNOWN if Hyundai is currently addressing this issue, but concerns about rear blinker visibility have been widely reported among Tucson owners and auto safety forums.

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.

I am filing a complaint regarding a serious safety malfunction in my 2025 Hyundai Tucson’s forward collision sensor, which caused an accident. I have owned this vehicle for only two weeks, and I believe this issue poses a risk to myself and other drivers. On February 25, 2025, while driving, the car in front of me stopped and made a U-turn. There was no imminent risk of collision, yet my Tucson’s forward collision sensor erroneously activated and engaged the automatic braking system. This caused my vehicle to come to an abrupt stop, resulting in a rear-end collision. I have documented the incident, including photographs, a police report, and insurance documentation, which I can provide upon request. This malfunction is extremely concerning, as a feature designed to prevent accidents instead directly caused one. If this issue exists in other Hyundai Tucson vehicles, it presents a severe hazard for drivers. I urge NHTSA to investigate this as a potential safety defect, determine if other similar complaints exist, and assess whether Hyundai needs to issue a recall or software fix. I also need guidance on whether there are any known remedies or if I should take my vehicle to the dealership for inspection. This issue must be addressed before it leads to more accidents. Please let me know if further information is needed.
