I have the 2019 Kona SEL. It’s hard to explain my issue with it, but the title describes what I’m hearing. When I take off under load, or a slight grade I hear some kind of shuttering noise that continues until I get up to full speed. It seems to be getting more frequent. This only started happening recently. However, if I wind down my window, I cannot hear the noise outside of the car. Has anyone had an issue such as this?
