My vehicle was the victim of attempted theft and reported to City of Cincinnati police 8/11/23. It then underwent repairs and delays before it was returned to me on 9/22/23. The left side rear door is basically detached from the system, causing the alarm to go off or not even work. The back seat lock is completely malfunctional, and there is glass remaining inside the car. I was informed by two separate Kia locations that they would contact me about repairs. On 9/29, notice attached here, I was informed that when a remedy is available, they will repair and cover the costs. No one has contacted me, and I have called multiple times over the last several months, including leaving voicemails, asking for any updates. I have phone logs I can provide as well. NOTE: The "Upload Files" button is not working below. Each time I click it, it just vanishes. This makes it impossible to attach anything.

My Niro has been having issues with sputtering, jerking, chugging, and feeling like it-??s about to stall. Sometimes it happens right when I start the car and sometimes it happens while I am driving. The check engine light just started coming on yesterday. I believe the transmission is faulty and have spoken to or taken it to the dealer with this same issue multiple times as it is covered under warranty. They keep telling me that-??s just how the car drives but in the 8 cars I-??ve owned in my life, I have never had a car that behaves this way before. An internet search of -??Kia niro transmission problems-?? proves that this is a common and known issue with this car that Kia is doing nothing to resolve. I have a daily 20 mile commute to work and feel incredibly unsafe driving my car and letting my teenage daughter drive it.

The service engine valve with "check active air flap system" error message is displayed. The diagnostic error that comes up is aaf - P059F. According to the dealer air compression test were completed and properly functioning. I have submitted 3 pictures with the same error message code to the dealer and they state not all saved in the car's ECM. The lights came on when starting as well as while driving. Noticed that the car takes longer to change gears or go into ev mode.
