2025 Hyundai Tucson Hybrid

On [XXX], my 2025 Hyundai Tucson Hybrid displayed a red dashboard alert instructing me to “stop vehicle and check brake system.” The vehicle experienced brake system warnings and a loss of power steering, requiring me to pull over. I immediately contacted Hyundai through the Bluelink system, and the Bluelink operator confirmed that multiple fault codes were visible in Hyundai’s system. I scheduled a Hyundai service appointment at the next available date. On [XXX], before the scheduled service appointment could occur, the vehicle experienced a sudden and total electrical failure while traveling at highway speed (approximately 65 mph). The vehicle lost propulsion and displayed brake system warnings. After reaching the shoulder, the vehicle also lost hazard lights while disabled in heavy rain. The vehicle was towed via Hyundai Bluelink to a Hyundai dealership and removed from service. The occupants at the time of the incident included my wife and my minor child. The loss of propulsion, braking warnings, power steering, and hazard lights created a serious risk of a rear-end collision and injury. Due to repeated and escalating safety-related failures involving electrical, braking, and steering systems, I no longer consider the vehicle safe to operate. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle propulsion system failed, as a result vehicle rolled down an inclined driveway in to the street and was stuck in the middle on the street in traffic. Vehicle had started normally, was able to shift into Drive, no obvious warning lights or error messages displayed. Vehicle would shift into Drive/Park/Reverse as required but would not move. Upon shutdown an restart two warning lights were display but Vehicle would still not move. Vehicle only had 168 miles on the odometer. Vehicle is a Hybrid, engine was running and Battery charged. Apparently the problem was a failed "Over the Air Software Update", this was corrected by Dealer (see attached file). Safety issue is that the Vehicle, 1 Failed to display any error regarding a Failed Update, 2 Failed to immobilize the Vehicle allowing to move in an unsafe state, 3 Failed to notify Owner that Updates had been done, 4 Proceeded with an over thew air Update that could potentially place the Vehicle in an unsafe state.

My vehicle was purchased new and has less than 5100 miles on it. The screen and heads-up display randomly begin to glitch and then simply go dark. I can't see my speed, fuel or charge levels or any important data while driving. This has happened multiple times already. My vehicle is a 2025 model. Interestingly, Hyundai had the same type issue on 2024 models and issued a TSB to resolve this issue, but have not issued any repair for the 2025 models. This is a major safety issue.

📌 NHTSA Complaint Description (Modify as Needed) 🚨 Safety Issue: I purchased a brand-new 2025 Hyundai Tucson Hybrid on March 3, 2025, and within 5 minutes of driving and less than 20 miles, the vehicle stalled three times on a busy highway without warning. 🚨 Component/System Failure: The vehicle suffered a complete power loss, rendering it undrivable in the middle of the highway. The gas pedal became unresponsive, and I had no control over the vehicle’s movement. 🚨 Immediate Safety Risk: The sudden stalling on a highway put my family and other drivers at serious risk of a collision. We were left stranded for over 3 hours while waiting for assistance. The vehicle was inspected by Hyundai’s roadside assistance and later towed to the dealership. 🚨 Inspection & Confirmation of the Issue: The dealership and Hyundai’s technical team later diagnosed the issue as a failure in the electric oil pump and the oil pump control unit. Hyundai has not provided a clear resolution and is pushing for repairs, despite the vehicle failing immediately after purchase. The manufacturer and dealership have not provided a pre-delivery inspection report confirming whether the vehicle was defective before delivery. 🚨 No Prior Warning Signs: There were no warning lamps, error messages, or any prior symptoms before the failure. The issue occurred suddenly and repeatedly within minutes of taking delivery of the vehicle. 🚨 Request for Investigation: Given the severity of this mechanical failure and its potential to cause serious accidents, I am reporting this to the NHTSA for further investigation. This issue needs to be addressed immediately before it leads to a fatal accident for another Hyundai Tucson Hybrid owner.
