I don't have a eco-boost. A couple different neighbors of mine and love it. No complaints of turbo lag. And no problem with the water in the inner cooler thing. The love the power and the great gas mileage. They talk of over 20 MPG in country driving conditions. Any vehicle can have problems. My brother bought a brand new f-250 diesel in 2012 and traded it off this summer because they could never get the thing to run right. There is a lemon made in every brand name and type of vehicle now and then. If you look for problems you will find them in anything.
