Automatic Transmission Control Module problems of the 2021 Kia Motor Sorento

I am submitting a complaint regarding a 2021 kia Sorento sx that experienced a premature and catastrophic transmission failure at approximately 76,000 miles. The vehicle developed loss of power, hesitation, and erratic shifting at low speeds (0–30 mph), creating a potentially dangerous condition when attempting to accelerate into traffic or cross intersections. A kia dealership diagnosed the issue as tcm code p193b79 and determined that the failure involved an internal high-pressure oil pump within the transmission, requiring full transmission replacement. This failure occurred despite proper maintenance and completion of kia’s sc250 software update, which appears to address transmission-related drivability concerns. My maintenance records confirm compliance with manufacturer recommendations. The symptoms and failure mode closely align with the type of transmission issues addressed in kia service campaigns and recalls (including scn-520), yet kia has refused to provide coverage or reimbursement, stating that my specific diagnostic code does not exactly match the recall criteria. As a result, I was forced to pay approximately $5,300 out of pocket for a full transmission replacement on a vehicle with relatively low mileage. This raises serious concerns that: * the underlying transmission issue may extend beyond the narrow criteria defined in the recall * software updates may not fully address an underlying mechanical defect * consumers may be experiencing similar failures without coverage additionally, the loss of power and hesitation at low speeds presents a clear safety risk, particularly in normal driving conditions. I am requesting that NHTSA investigate whether transmission failures in the 2021 kia Sorento are broader than currently recognized and whether affected consumers should receive expanded coverage or reimbursement.
