Severe structural manufacturing defect in my 2021 Kia Sportage. A physical hole has formed in the floorboard on the driver side directly next to the pedals, creating an immediate risk of a catastrophic accident. The vehicle also has chronic failure of the air conditioning system, documented by Sunset Kia of Sarasota as a leaking evaporator. This prevents the windshield from defrosting during heavy Florida rains, severely impairing visibility. Dealer confirmed these hazards under a signed repair order on June 3 2026, but Kia Corporate closed case 25175676 without any physical technical inspection, leaving an unsafe vehicle on the road.
