The style bike rack that I use has several adjustable straps that connect using 6 vinyl coated hooks that go over the edges of the hatch(2 on top,2 on bottom and 1 on each side) plus the padded crossbars that lean against the lower portion of the hatch below the window and I have never had a problem hauling 3 bikes on it. just try to adjust the straps so that the bars arent laying directly on the window as the vibration could possibly cause it to crack.
