Quality has to start with great component designs and everything has to be designed for manufacturability. So many young engineers are told to sit in front of a computer and design a part and they have no idea how it's manufactured. So the design becomes overly complex, almost impossible to manufacture with repeatability and the quality suffers for the life of the program. Ford has failed miserably on this on so many occasions it's hard to believe they have any customers left. So many issues come to mind, not the least being the breaking spark plugs in the past.
