So, my wife's 2007 Edge has 126k on it. It's in great shape, but we're considering upgrading to get some of the newer options like Sync, etc. We've been looking at 2015 and 2016's. It will be a similar platform for her - AWD, sunroof, etc. From there, we're now faced with the engine choice. We drove a rental Edge almost 800 miles with the Ecoboost. Frankly, it performed fine for us. It had the "go" we needed; though, I admit you had to get into a bit more than we were used to in the 2007.
My concern, though, with the 3.5 are the issues I read about with the water pump. I see it across the Explorers, Taurus and then the Edge. Clearly there's a design flaw/issue there. On the other side of the coin, the direct injection engine causes me to pause, too. I have that in my Explorer Sport and I can already tell it's starting to chug a bit after 75k - despite top tier fuel use and frequent oil changes.
So, what's the lesser of two evils - a chanced water pump failure that costs thousands, or a caked up direct injection engine?
We'll buy one with somewhere between 15k-30k on it as she puts about 8k a year on a car, so it will be with us for a while.
Look forward to the thoughts - thanks! Shumax
