2025 HYUNDAI TUCSON HYBRID

FUEL/PROPULSION SYSTEM

📌 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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

I have had two incidents where the emergency braking system applied itself when there was no reason for it to do so. Both times there was a car in the distance, over 20 feet away that was slowing, and I was slowing as well. The second time it happened, it was with great force and I was fortunate that the car behind me was able to brake in time and avoid rear ending me.
