2013 Mazda 3 Hatchback Knocking under drivers side
My new 2013 Mazda 3 Hatchback with 1k miles has developed physical knocking directly under my left foot when I take off. I am really concerned. It feels like a rock is hitting underneath the floor. I thought I was dragging a branch or something. It actually feels like I am running over something. It stops as soon as I am out of first gear. Anyone have any ideas?
