Please bear w/ a noob here. My car downshifts quite abruptly and slows down significantly during coasting. It doesn't allow me to coast smoothly then brake let's say to a red light, it'll slown down to the point that I feel it'll come to a full stop if I don't give it some gas and even if I don't step on the brakes. When I allow it to slown down like this it then has a hard time "recovering" for acceleration. It also has this strange habit of "surging" when I lighten up on the brake pedal during braking, i.e. I have to exert constant and strong pressure while braking otherwise i'll feel a surge of speed. Thanks for your opinions before I call the dealer service dept.
