Mine does this (2020). At least I think it is what you describe. I thought it was just the sound of the valves closing and never questioned it. Mine does it a lot going from 3-4 or 4-5 puttering around town which is kind of annoying. I put the car in manual mode if I don't want to hear it. I really don't know if it can even be fixed. As much as I don't like it, it really is a minor annoyance for me. It's really the only thing I can think of that I don't like about the car.
