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

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 underbody shield is held up partially by plastic nuts that get loose casing the shield to rattle at speed over 60mpg. I read multiple reports from other owners on reddit. Tightening these plastic nuts help ressolve the rattle temporarly, but the nuts are flimsy and keep spinning. You can't really tighten them well. A good remedy from Hyundai would be to replace these flimsy plastic nuts with metal ones that stay tightened and secure the underbody shield in place. Dealer wasn't helpful and wanted to charge $200 just to look at it

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.

The contact owns a 2025 Hyundai Tucson. The contact stated that while exiting the vehicle, he opened the front driver's door and scraped his leg on the edge of the door. The contact stated that shortly after, he and his wife noticed a significant amount of blood coming from the cut. The contact sought medical attention a few days later. The contact's wife added that the contact was diabetic and takes blood thinners. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, a complaint was filed, and an engineer was sent to take pictures of the vehicle. The failure mileage was approximately 13,000.

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.
