2021 Kia Sorento

I was driving up a hill and my car stalled. Contacted Kia of Bowie for assistance had a diagnostic asked for a goodwill repair because of this being a safety issue with my car stalling while driving up a hill life threating situation and they have denied the goodwill repair the service tech is saying because I didnt get my car serviced there and they have no records I informed them that I have and had been taking care of the maintenance at the Kia dealership in Temple hills md. They are just overlooking the severity of the situation of a safety issue.

Intermittently, when coming from a stop (stop sign, red light, etc) or recent start of the vehicle, the Sorento will not accelerate past approximately 30 miles per hour and the auto-stop light will flash orange in the panel. Once the vehicle is stopped, turned off, and restarted, it goes back to operating as it should and accelerates like normal. This has happened when driving on small, low speed limit roads and on large, high speed limit roads. My safety and the safety of those driving around me is put at risk when vehicles around me are expecting me to drive a certain speed but I can't and am looking for a safe place to pull over to stop and restart the vehicle. To date, the vehicle acceleration has not suddenly dropped from a high speed to a low speed thankfully, but when the issue presents itself, it will not allow the vehicle to accelerate above the 30mph range. The vehicle is available for inspection upon request. It is currently at a dealership that is working to reproduce and confirm the problem. There are Reddit threads that discuss other Sorento owners experiencing this same issue. To my knowledge, there were not any warning lamps, messages, or other symptoms of the problem prior to this issue presenting itself. It has been happening on and off for the last 1-2 years. My vehicle has not been inspected by the manufacturer, police, insurance representatives, or others but I am happy to have any of them do so. A simple battery replacement has not resolved the issue - it was happening before I had my battery replaced and it has happened since having my battery replaced.

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.

Back in June 2025 my car started having an issue with the auto on/off light blinking on the dash and unable to be turned off. While driving and this happens, the car is unable to maintain its sped or accelerate. This has caused safety concerns many times. Dyer Kia first said it was an update, problem still remained. Then they said a deeper update was needed to no avail. The third attempt was a new transmission which caused more problems and still did not address the initial issue. Then they said it was the battery. They installed/ replaced an already new battery yet the problem still existed. Another transmission was put in and the problem still existed. Then they replaced the TCM and the issue still exists. The car is at a new dealership and already they are saying they have not found any codes to explain the problem yet and that they need to repair the battery terminal leads that the previous dealership broke before they are able to go further. Kia corporate is not helping me find a permanent solution to this issue and I still do not have my vehicle.

I have had many issues where my car will completely shut off after the auto start-stop function causing me to almost get into accidents with my toddlers in the vehicle. There was one incident where I was at a stop light, when the light turned green I started my car again to go and another vehicle continued to bypass me. When i halted for the other vehicle, my engine shut off again almost the cause of a horrific accident. I have had many incidents after this with the related cause of engine shutting off.
