I was sold a vehicle with a manufacturer defect. At purchase there was a loud wind noise coming from sunroof. I was promised a swift service department visit to realign the sunroof. At service visit ten days later the dealership replaced sunroof and threw electrical error codes B271100. After a specialist over rode the error the dealership claimed fixed and had me pick up the vehicle. The loud wind noise was still present. When I attempted to return the vehicle the dealership said I would no longer be serviced by their dealership. Kia Customer Care sent me to a second dealership. Second dealership brought in techline specialist that ordered Kia Warranty repair would replace the entire roof. The vehicle is at a third party auto body repair shop.
