Owner's description
Vehicle subject to NHTSA Recall 25V796000 (fuel system defect). In July 2025, while driving, a loud explosive sound came from the rear of the vehicle followed by raw gasoline fumes entering the cabin. Vehicle was towed to a Hyundai dealership and held approximately 120 days before being returned as repaired. In December 2025, the exact same defect recurred. A third-party diagnostic scan (performed before drop-off) confirmed DTC Code P14EE — Fuel Tank Check Valve / Evaporative Purge System failure — directly related to the recall. The vehicle was held an additional 110+ days while the dealer awaited a new remedy from the manufacturer. Total days out of service: 230+. The recall repair has now failed twice. The safety defect was never successfully corrected after a reasonable number of attempts. The vehicle is currently being withheld by the dealership pending an unrelated disputed repair charge.
