Folks have wondered about the open tow hitch chamber on the X: you remove the plastic dust cover to install the tow hitch. Won't the compartment fill up with mud and schmutz?
The DIY fix?
Get a spare plastic dust cover. Not sold in stores! Sweet talk your dealer or service center into giving you a spare. (Ours asked for $2, then waived the fee after a glitchy repair...)
Drill a hole in the plate about 2.5" diameter centered over the center of the vertical tow hitch post as shown:
Takes about a minute with a Dremel.
You should be able to just barely work the hole over the wedge-shaped cross piece. The surface of the plate will fit in between the bottom of the wedge and the top of the rest of the tow hitch.
1. Set your car suspension height to "Very High."
2. Remove the dust cover. (Use a thin flat head screwdriver to pop loose the two plastic buttons and then snap out the cover).
3. Put the tow hitch through the holy dust cover. Using the key, "open" the tow hitch and rotate the knob forward to get it ready for insertion as usual.
4. Slide the back lip of the cover into place (in the rearmost part of the opening), positioning the hitch post. Snap the hitch into place, snap the dust cover hooks in place and pop the plastic buttons back in. Ready to roll.
