??"? 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.

-auto start/stop "feature" Since there is no way to permanently disable this feature i forgot that it was on. while stopped a stop light i was unable to move when the car behind me could not stop due to the wet roads. If the car behind me was unable to swerve in time i would have been rear-ended. by the time the engine started the car behind me was in line with my back seat. no amount of gas saving is worth being immobilized essentially in a emergency situation. - forward collision avoidance is way too sensitive, in the same trip as above a car hit their brakes approximately 6 car lengths in front of me to turn into a parking lot. the car in front of me did slam on their brakes to make the turn. As i took my foot off the gas to slow down the "safety feature" activated, applied my brakes and almost caused the car behind me to rear end me. i was going roughly 45 mph and the car behind me was roughly 2 car lengths behind me when the "safety feature" activated. the sensitivity of this system is way too high and will wind up causing more accidents then it prevents

On Jan 5th, with odometer reading of 1747 miles, while driving on a busy highway, the car's speed decreased until the car stopped without warning. After pushing the car into a gas station to get out of harm's way, we contacted Hyundai roadside assistance. The car was towed to a nearby Hyundai dealership. The problem was diagnosed the next day - the car needs a new transmission. The transmission is on backorder and will not be delivered to the dealership until the middle of March. Our new 2025 Tuscon Hybrid will be out of service for at least 10 weeks after breaking down on a major road without warning. The code is the bluelink app is P177700 -Powertrain transmission
