"The vehicle has twice suffered a sudden, catastrophic loss of motive power at highway speeds (approx. 70 MPH) on the interstate, forcing the driver to coast across active traffic to the shoulder without engine pull. The engine revs freely in 'Drive' but the transmission fails to engage any gears. No dashboard warning lights, check engine lights, or diagnostic trouble codes are triggered during or after the failure. The failure resets temporarily only after cycling the ignition key off and on.The vehicle previously had Safety Recall SC250 (8-speed Electric Oil Pump) performed by an authorized dealer, but the software flash completely failed to prevent this catastrophic hydraulic/electronic failure mode or provide the federally mandated dashboard warning countdown. The vehicle is entirely unsafe to drive,

previous warranty repair for a failed fuel injector (RO #1103175) resulted in severe gasoline dilution of the engine oil. the vehicle now vents raw fuel vapors into the cabin (Fire Hazard) and hesitates/jerks when braking at stoplights (Stall/Crash Hazard). Kia Corporate has refused to communicate for over two weeks while the dealer holds the car.

I am filing this complaint regarding my 2021 Kia Sorento, which has suffered a serious transmission failure. The vehicle is displaying diagnostic code P0741, indicating a torque converter clutch malfunction. The transmission slips, shifts harshly, hesitates during acceleration, loses power unexpectedly, and has become unsafe to drive. The vehicle is available for inspection upon request.This defect has put my safety and the safety of others at risk. On several occasions the vehicle failed to respond properly when accelerating, including while entering highways and driving in traffic. The hesitation and sudden loss of power created fear and anxiety because I could not trust the vehicle to move when needed to avoid a dangerous situation. The problem has been reproduced and confirmed by a repair facility, and the symptoms are consistent with a transmission torque converter clutch failure. I also contacted Kia and provided the vehicle information. Kia informed me that they would not repair the vehicle because it has exceeded 100,000 miles and that the recall or warranty extension had expired. However, my vehicle is experiencing the same transmission-related symptoms reported by many other Kia owners.I never received any recall notification because I purchased the vehicle from a dealership as the second owner. Had I been properly notified, I would have taken the vehicle in for inspection much earlier. It is extremely frustrating and financially devastating to be denied assistance solely because of mileage when the failure appears to be related to a known transmission defect.Before the failure, the check engine light illuminated and code P0741 appeared. Prior to that warning, the vehicle had already shown delayed shifting, slipping, hesitation, rough gear changes, and loss of power, which became progressively worse.This situation has caused significant emotional stress, anxiety, and financial hardship. I am requesting a full investigation and a fair resolution from kia.

COMPONENT: 2.5L T-GDI engine failed completely at 102,971 miles, requiring full replacement (~$8,000). Vehicle available for inspection at [XXX] Kia, [XXX] . SAFETY RISK: Engine lost power during normal operation. Sudden, uncontrolled loss of engine power creates a direct collision risk at highway speeds for the driver, passengers, and surrounding vehicles. CONFIRMED BY DEALER: Mark Kia performed a borescope inspection on April 10, 2026 confirming cylinder wall scoring, oil-fouled pistons, and worn honing patterns across multiple cylinders. Findings are consistent with Kia TSB ENG235 (January 2022), which documents a defective PCV check valve on 2021–2022 Sorento 2.5T engines allowing oil to contaminate combustion chambers. Vehicle was serviced exclusively at Mark Kia for all 17 visits since 2021. TSB ENG235 does not appear in any service record. PRIOR SYMPTOMS: No warning lamps or messages before failure. A certified 36-point inspection one week prior showed zero cautions. Spark plugs replaced at 74,534 miles (Jan 2025) were found fouled at ~102,000 miles, only 28,000 miles later — indicating silent, progressive oil contamination. The defect is undetectable by the driver until catastrophic failure. Kia America has not responded to two formal written dispute requests (Case #XXX, April–May 2026).

The system that failed is the high-pressure fuel pump and the intake fuel pump. The fuel system pressure is too low, and the cold start fuel pressure is too high. This is defective because I purchased the car used in November 2023. The car is a safety risk as it stalled immediately yesterday while I was driving with my children and it began smelling like gas fumes from exhaust. The vehicle has been diagnosed by a certified mechanic at Mike and Nick's Tires and Services in Canyon Country, California No warning lights or messages appeared prior to the failure. The engine light came on as soon as the car began to stall and shake/lose power.

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 the federal safety agency investigate whether transmission failures in the 2021 Kia Sorento are broader than currently recognized and whether affected consumers should receive expanded coverage or reimbursement.

Referencing report [XXX] We are having issues getting the fuel filling door to open. We have unlocked the car, several times, but it will not open. We had to pry it open so we could fill the tank and have left it open since as to not have the issue again. Part number in question - 81560R5000 There are other recalls on the car that we need to get taken care of. Is this another one in addition?
