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

The horn in our 2025 Hyundai Tucson failed. We took the vehicle to two separate dealerships to get replaced, but were told the horns were out of stock with no ETA for parts. I followed up multiple times over several months with both dealerships, but got nowhere. This is a huge safety issue. How can Hyundai not correct this issue?

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.

I had the Car's instrument panel go totally blank in March 2025 on my new 2025 Tucson Hybrid while driving on my first long distance trip. I took it to my local Hyundai dealer to have the issue looked at upon my return home, but they could not replicate the problem and therefore could not help me. I had the exact same issue of the instrument panel going out again on my latest long-distance trip in December 2025. I have not taken it in for service since the first time this problem happened as they said they couldn't replicate it. It only has happened when driving long distances and not on any of my local driving.

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

NHTSA Vehicle Safety Complaint Report I am submitting this complaint regarding a serious safety defect involving the rear seatbelt in my 2025 Hyundai Tucson Limited. The vehicle currently has approximately 6,000 miles, and this issue has created an extremely dangerous situation for passengers. While traveling out of town, the rear passenger seatbelt suddenly jammed and would not retract or release properly. The belt became completely stuck and unusable. Three adults attempted to safely unjam the seatbelt, but it would not retract or function as designed. Because the restraint system failed, the rear seating position became unsafe and unusable. We were forced to arrange alternate transportation for our passenger because it was not safe or legal for them to ride without a functioning seatbelt. This failure represents a major safety concern. A seatbelt is a critical safety component that should never lock up or become permanently jammed under normal use, especially on a nearly new vehicle with very low mileage. The inability to secure a passenger created a hazardous situation and could have resulted in serious injury if an accident had occurred. I am contacting Hyundai Customer Affairs today to formally report this safety issue. I will also be taking the vehicle to the dealership for inspection and repair, as I do not feel it is safe to drive the vehicle until the defective seatbelt is properly repaired and confirmed safe. Given that seatbelt failures directly impact occupant safety, I believe this issue requires immediate investigation. A restraint system that becomes stuck and cannot be used is unacceptable and poses a significant risk to drivers and passengers. I am requesting that NHTSA review this defect, investigate potential manufacturing or design problems, and determine whether other vehicles may be affected.

On January 25, I was driving on the freeway and my moonroof front panel exploded. It was a loud bang, and completely unexpected. This could have caused an accident. After the glass exploded, I pulled over only to realize the glass had hit another cars windshield and broke their windshield. I am lucky this didn’t cause an accident.

there is a "consider taking a break" / coffee cup message that appears on the dashboard and BEEPS uncontrollably. It is annoying and distracting. It is of ZERO VALUE since it is always FALSE. It came up 5 times on my first 45 mile highway drive. this is NOT safety feature and in fact is REDUCING safety as it it annoying and makes me frustrated/mad instead of calm. Hyundai says there is no ability to disable it/turn if off as there was in their previous models.

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.

During normal winter operation with the heater in use, the center console area becomes excessively hot. I have measured surface temperatures exceeding approximately 130°F using an infrared thermometer. The affected area includes interior touch surfaces, cup holders, and a factory-installed wireless phone charging pad. The heat appears to originate from HVAC ducting routed through the center console to supply the rear seat vents. Closing the rear vents does not reduce the console temperature, indicating heat transfer through the ducting rather than airflow. The condition is most severe after a warm-soak cycle (driving to operating temperature, briefly parking, then driving again). When a phone is placed in the intended storage or wireless charging area, the device overheats and triggers thermal protection warnings. The console surfaces also become hot enough to present a potential burn risk with prolonged skin contact. These temperatures exceed recommended ambient conditions for consumer electronics and lithium-ion batteries in a normal-use interior storage and charging location. The issue was reported to a Hyundai dealership. The service department stated the heat was caused by the rear HVAC duct and considered the condition “normal.” No repair, insulation review, or corrective action was offered, and no specific temperature measurements were provided in writing. Hyundai Consumer Affairs directed me to return to the same service department, despite the concern remaining unresolved. This condition occurs during normal vehicle operation and represents a potential interior thermal safety concern.

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.

I’ve been driving this car for nearly a year, and during that time I have observed 6+ incidents when my instrument cluster went blank and rebooted in the middle of the road while the vehicle is moving. This seems to be widespread issue with no resolution from Hyundai what so ever. I have raised this issue with Hyundai as well.
