Consumer Description

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.
