Hi, I bought this Kona from the dealership in 2024. About six months after it started making this weird noise. As you can hear in the video the grinding is the auto hold break dragging through. I'm not sure what to do. I've taken it to the dealership and gotten a rental multiple times and they say nothings wrong with it and it won't happen when they have it. Resting RPMs range anywhere from 1.1-1.5 when in park and sitting at a light. Has anybody else had this issue?
