This says it all:
Investors also have to remember the difference between J.D. Power studies. This one, the Vehicle Dependability Study, covers 2013 model-year vehicles owned for three years. That's back when Ford's MyFord Touch was basically a disaster, and J.D. Power notes that many problems in the study were design or infotainment/technology related, while engine and transmission problems -- much more serious, in my opinion -- declined from the prior-year study.
Taking that a step further, consumers and investors live in the "What have you done for me lately?" world. In that world, J.D. Power's 2015 Initial Quality Study, which covers brand-new vehicle models, shows Ford scored 12th, and above the industry average. That suggests that Ford has already figured out the minor problems that held it back with its 2013 vehicle models.
