Consumer Description

My 2018 Kia Sportage (2.4L Theta II GDI engine) suddenly triggered diagnostic trouble code P1326 (Knock Sensor Detection System – Detection of Excessive Connecting Rod Bearing Wear) and entered limp mode at 111,595 miles on Sep 13, 2025. The vehicle is now speed- and RPM-limited to protect the engine from catastrophic failure. This is the exact failure mode covered under the well-documented Hyundai/Kia Theta II engine defect that has led to thousands of engine seizures and, in some cases, vehicle fires. Kia implemented the Knock Sensor Detection System (KSDS) software update (Campaign SC200) on this VIN, yet the system has now correctly detected excessive connecting rod bearing wear. Despite the vehicle falling squarely within the class vehicles listed in the 2020–2023 Hyundai/Kia engine litigation settlement (In re: Hyundai and Kia Engine Litigation II), Kia’s settlement VIN-check website [XXX] ) incorrectly states this VIN “has not been matched with an eligible Class Vehicle.” I am concerned this may be used as a pretext to deny the lifetime short-block warranty repair that other identically-equipped 2018 Sportage owners have received at no cost. Continued driving risks sudden engine seizure or fire, which NHTSA has previously investigated under PE21-003 and related actions. I am forced to keep the vehicle parked until Kia honors the repair or provides clear justification for denial. I can no longer safely use the vehicle for normal transportation Requested action: I request that NHTSA investigate Kia’s inconsistent application of the Theta II lifetime warranty and settlement benefits, particularly when the KSDS system (installed by Kia) has triggered the exact warning it was designed to detect. This appears to be a continuing safety defect affecting 2011–2019 Kia vehicles equipped with the 2.4L Theta II GDI engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
