All of a sudden I see the service due sign everything I turn my car on... Thing is I only had it since July when I bought it new. I don't know why I need servicing so early. And when I turn on my car, I hear the sound of running water on the drivers side from around the mid point of the drivers door and the back seat door on the right side. This happed after I lowered my car down with a floor jack: both the sound and the service sign. Why is this happening?
