As somebody who does his own automotive repairs, I'd call that "A Problem".
There should be NO PLASTIC PARTS within 2" of the exhaust system. Preferably 6".
That is some really poor engineering. The cable can slip from the clip too easily. The quick fix would be to get the cable under the clip and run a self-drilling and tapping screw through the tail of the clip to guarantee the cable stays put.
Then have Ford issue a new cable that routes no where near the exhaust system.
