NHTSA Complaint #11639596 — 2021 KIA TELLURIDE

I’ve taken my vehicle to Kia a few times about my transmission sputtering and the first time they told me I needed a transmission flush, I paid $250.00 to have it done just to have it continue to happen and every time I bring it there they say they aren’t seeing or feeling anything. It’s still doing it. Also I opened my sunroof and it hasn’t been used much since I bought it in 2022 and now it’s stuck open. Took to the dealer just for them to tell me I have to pay $140 diagnosis fee and my warranty most likely won’t cover to fix it. I purchased the platinum bumper to bumper warranty!
