Within 5 years, and less than 60k miles, yes. It should be covered.
After that, even including the 10/100 Powertrain coverage, at least by the letter of what I have read, it would not be covered. There's a list that includes all that is covered in the 10/100 Powertrain Coverage (post 5 years or 60k miles), and the cable is not listed there.
I'll read more about it.
