2021 Kia Sorento: complete transmission failure

Filed Nov 2, 2026 · Transmission · MN

My 2021 Kia Sorento (VIN [XXX]) is at Luther Kia. The dealership documented DTC P1C2D03 as stored. Kia's SC250 recall procedure states that if P1C2D03 is not stored, the dealer updates the TCU software only; if P1C2D03 is stored, the transmission is to be replaced and updated TCU software applied. Despite the stored code, Luther Kia did not replace the transmission. They updated the ECU, rescanned, performed an air-bleed procedure and transmission relearning, test-drove the vehicle, and marked the repair complete. I am concerned this does not comply with the remedy specified for stored P1C2D03 and leaves the vehicle susceptible to the loss-of-motive-power condition addressed by the federal safety agency Recall 22V760000/SC250. After receiving no update since late morning XXX, I called near closing XXXand was told their only Authorized Kia Warranty Service Technician was out sick. That evening I emailed the GM documenting the SC250 concern and requested resolution by Monday morning, including release of my vehicle while the transmission was ordered or a loaner/rental if unsafe to release. As of Monday afternoon, I have received no response. I also opened a case with Kia Corporate on XXX. The dealership sent me a $528.28 invoice via text and is retaining my vehicle pending payment of the entire invoice. This includes $178.98 I understand to be recall-related diagnosis/labor, although SC250 states there is no charge to the owner for this repair, plus $311.36 for A/C diagnosis and a $36.94 miscellaneous fee. I was instructed to drive approximately 1,000 more miles for the A/C issue. The odometer is approximately 99,2XX miles, which would exceed 100,000 miles and may affect CPO warranty coverage. A rear clunking concern potentially related to Kia TSB TRA105 was not resolved. I request the federal safety agency investigate whether SC250 was properly completed and whether this vehicle is safe to operate without the transmission replacement specified for stored P1C2D03.

Vehicle: 2021 Kia SorentoCurrent Mileage: Over 100,000 miles (Original Owner) Description of Safety Defect & Failed Recall Remedy: Background: This vehicle is equipped with the 8-speed Dual-Clutch Transmission (DCT) and has suffered from severe slipping, jerking, and hesitation since delivery (at 5 miles). In 2023, the vehicle received the software update remedy under Kia Safety Recall SC250 (the federal safety agency Campaign 22V760) for the defective electric oil pump circuit board. The Failure: The 2023 software patch failed to resolve the underlying physical safety defect. An independent technician recently diagnosed the vehicle and confirmed a permanent, un-clearable fault code for a completely failed electric transmission oil pump—the exact physical component failure targeted by safety recall SC250. This defect causes an immediate risk of a sudden loss of motive power. The Dealership Violation: The vehicle was dropped off at Greenway Kia West Orlando on Monday, August 17, 2026. The dealership held the car for over a week, logging it under a separate fuel pump recall to stall. On August 25, 2026, the dealership formally denied safety recall coverage and issued a $7,000 out-of-pocket quote to replace the transmission, claiming the vehicle is no longer covered because it is past the 100,000-mile powertrain warranty. Federal Mandate Violation: Under federal law, safety recalls do not have mileage caps. The manufacturer's remedy failed to permanently correct a documented safety hazard, and the dealership is actively attempting to shift a multi-thousand-dollar safety recall replacement cost onto the consumer.

I am filing this complaint regarding my 2021 Kia Sorento, which has suffered a transmission failure. The transmission slips, shifts harshly, hesitates during acceleration, loses power unexpectedly, and has become unsafe to drive. 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 operate as expected. 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 or would never have purchased the dangerous vehicle in the first place. It is extremely frustrating and costly 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 then went away even though the issue did not. Prior to that warning, the vehicle had already shown delayed shifting, slipping, hesitation, rough gear changes, and loss of power, which became progressively worse. I reported this to Kia on a previous service visit to Romeo Kia in Lake Katrine, NY and was told they did not find anything wrong. This situation has caused significant emotional stress and anxiety. I am requesting a full review and a fair resolution from kia. Thank

My vehicle lost power and accelerated quickly yet unpredictably, and the check engine light came on. A local shop told me it was "an old code" for the transmission and that if it does that again to take it to dealer. It occurred again. Kia dealer states this vehicle has a recall and has been repaired twice, but that they will not repair it again. This is such an unsafe issue they will not allow me to drive the vehicle. I will have to pay almost $7,000 to replace the transmission.

The vehicle experienced a sudden loss of drive power and entered a 'fail-safe' mode with check engine light, warning chimes and service vehicle warning message. A diagnostic scan revealed fault codes P1C2D03 (High Pressure Electric Oil Pump Motor Position Sensor), P193B79 (High Pressure Electric Oil Pump Performance), and P086800 (Transmission Fluid Pressure Low). These three specific codes are cited in Kia Recall SC250 (the federal safety agency 22V760) and associated technical bulletins as evidence of an internal electric oil pump failure requiring full transmission replacement. The safety of occupants was compromised by the sudden loss of motive power on the interstate. I presented these codes to Value Kia 6915 Essington Ave, Philadelphia, PA 19153 and dropped my car off on 4/7/2026. The dealer stated the safety recall was 'closed' and that the vehicle was 'out of warranty' due to its 95,000 miles and second-owner status. They would only agree to perform a diagnostic at my personal cost. The vehicle has been at the dealership for two days without an inspection report being provided to me. I have contacted Kia Corporate Consumer Assistance (Awaiting Response) and am filing this report because the vehicle is exhibiting the exact safety defect and 'triple-threat' fault codes of SC250 but is being denied a free safety remedy by the authorized dealer due to mileage and second ownership. As of 4/9/2026, the vehicle has been at the dealership for 2 days. Despite signing an authorization for a $190 diagnostic fee, the dealership has been completely silent and has not provided a status update or the diagnostic report. I am being left without transportation while the dealer fails to address a documented safety defect.

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.
