My take on these cars from ford (pretty much anything with an ecoboost), be it SHO, explorer, MKZ, Fusion Sport, you name it... It will be a rats nest of problems in 10 years and 150,000 miles.
Let me explain. 2 reasons why I feel this way;
1) When I buy something, I buy it with intention of keeping it WELL past warranty expiration. My Suburban is 18 years old, my GTO is 13, My Cadillac is now 11, my older Chrysler van is 10 years old, the Impala is now ~8... I think you see my trend there. At which time, that means those costs to maintain and repair are on my dime, and not to mention, my time is money. Of all those (the exception being the Cadillac), all are K.I.S.S. pushrod V8's or a V6. Parts are dirt cheap, Parts are plentiful, Parts on the GM's in some cases are interchangeable, and they're stupid easy to work on. When you factor in additional complexity of turbos, intercooling, plumbing that goes along with it, heat, etc, etc., these new TTV6 wonder engines become a nightmare to work on.
Which leads to point 2
2) I worked on cars (GM) for a living. My time is money and I get paid to move sheetmetal through my two stalls. While I can't spend all day doing PDI's and oil changes (I would love to though), I dread when something like this came in because I get charged book time on what the manufacturer says it will take to repair their wonder contraption. Sometimes that time works, however, many times, especially the first one or two you do and you develop that learning curve, you end up losing and it takes money of your pocket. Meaning, I'm stuck working on something that is a stubborn PITA and not getting paid for my time over the book time, when I could me moving on to a simple fuel pump on a Tahoe. Take all that additional complexity then add in the fact that 99.999999999999999999999% of the people that own/will own these, don't take care of the friggen thing, only complicates matters. "Oh, my turbo uses the engine oil to lubricate the bearings? I guess that 7,500 mile interval I was doing probably wasn't the best idea...", "Oh, coolant last 150k?" I've got 175k on it... "Oh you mean I have to change plugs?? The manual says 100k..." Arrgggg.,.. The problem really becomes an issue for owner #2, 3, and so on.
And I guess a third point... V8, M6, RWD > *
