  1. The Gentle Grizzly

    What is it with Ford, and their rear suspension errors? This seems to be a recurring issue with them.

  2. Roy Chile’s

    Man this is going from Bad 2 Worse news for the 21 Aviator and Explorer

  3. David

    Yup, in the Explorer ST models they put in the wrong subframe.

  4. Doug

    20 vehicles. Not exactly a huge problem here, hardly worth reporting (assuming Ford can easily identify and fix the affected vehicles, which they should be able to do)

  5. Bill

    This is what happens when you check the right boxes when hiring instead of hiring the best candidate.
