Are you tuned? If so, reach out to your tuner.
mine did this in the winter after my tune but now it no longer does. Maybe the car self taught itself? Not sure…. But it only happened in the winter right when I got a new tune. I let it keep happening for a month or 2 and it went away

It’s normal. Car is letting you know that it’s cold and not to beat on it yet. Kinda like when you shake right affer you pee.
