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 the federal safety agency 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 the federal safety agency 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.

Stuck in gear or won't shift by model year
What owners say
My 2018 Kia Sportage (VIN: [XXX] ) triggered a check engine light and entered limp mode. Diagnostic scan revealed DTC code P1326, which is associated with the Knock Sensor Detection System (KSDS) and often linked to engine bearing failure in many affected Kia models. This happened at approximately 120,000 miles while driving under normal conditions. The car now runs in reduced power mode, making it unsafe for highway use or commuting. I contacted my local dealership, who confirmed no recall or campaign was active, despite this being a widely known and reported safety defect in Kia’s 2.4L GDI engines. I am requesting the federal safety agency to investigate this issue further, as many Kia and Hyundai vehicles with this engine have experienced sudden failures due to this defect. Kia should extend warranty support or issue a recall to prevent dangerous engine shutdowns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
9/15 car goes in limp mode on expressway. Get to towed to dealership. Get the car back on 9/17. Only make it about 20 miles, and the same thing happens again. I’m able to make it back to the dealership the same day. On my way home. Pick up the car on 9/19. Happens again on 9/20. Now I am being told I need a full engine replacement. The dealership has no loaners to give out. They are expecting me to pay for a rental in hopes of getting reimbursed. I am a single mom. I work in sales and drive in my territory every single day I do not have the money to put out for the rental and now after researching, it could be months before I get the car back.
Kia motors is at it again, my Disabled Husband took car in twice to Dealer, who is licensed to sell and fix your vehicles , promised loaner car, on fixed income, fighting Cancer, see attached documents, emails from KIA, been going on 7 years, first Soul now Sportage. COURTESY KIA OF BRANDON , months BACK came to our home and allegedly did the LATEST RECALL ON FUSES, thought that was done, Courtesy KIA of Brandon told my husband NO OUTSTANDING recalls, now KIA writes and states needs to be done? Who is keeping records. We had kids put on couple years ago, then car went into limp mode almost got my husband killed. Kia had our car towed, brought loaner. WE CANNOT afford rental. That was halfway repair with ext on wiring harness???, now lights on dash going on and off. See attached, KIA could care less and now, we were lied to? The person they sent didn't repair the Fuses? Kia paid the Government a fortune in fines but the Defective car owners are always in danger and always getting the run around. [XXX], Mr. [XXX], plz excuse spelling. Even [XXX] from Safety Organization says these cars need to be off the road. Our car is malfunctioning, and we were blatantly lied to is RECALL ON FUSES? REPAIR. SENATOR [XXX] HELPED WITH THIS, we need someone to step up. [XXX] and [XXX], see all documents going back to 2015. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
Addendum to the complaint dated january through senator marco rubio office. I received a letter from the federal safety agency dot that the investigation is open as to the "software upgrade", should be labeled recall and into the "theta engine", see attached. As I write this, my disabled husband is in a tow truck with the driver because he went to the dollar general store, turned the corner onto a busy highway and the car limp mode light came on, car shut down dangerously slow. Luckily he was not rear-ended. This is pathetic for kia motors, kia america to get away with this. These vehicles need to be bought back. They have no clue what is really happening. We took our car in a couple of months ago to courtesy kia for an oil change. They said all was good. Clearly it is not ! Kia did us, two disabled americans wrong. Soul 1st, scammed into going more in depth because soul was bad... Knowing there is a major defect. That is deceptive trade practice. Plain and simple and dealer's are complicit. Please get these cars off of the rode. It has been noted on forums that kia is putting used motors. Please do something. We are not safe, our grandchildren are not safe. States attorneys, attorney general's, senators, etc. Help all of us. We lost our home to toxic drywall , now this. Plant city. ♿
