I recognized that when I drive as 21mph, suddenly operate brake even I didn't push the brake pedal like engine brake and then if mph became 12mph, suddenly released the brake. Is it normal? I think it's because of i-eloop system But! I don't have that option. I don't know why my car has problem with that. anyone have same problem with me? Or please let me know is it normal? Or it's problem. Should I go to dealership? Thanks!
