Is it just me or does it always seem that Ford's Ecoboost engines always use more fuel than what the numbers say? Other manufactures with turbos are more inline with rated numbers but why isn't Ford?
It actually gets worse with mileage. I had a '13 Explorer Sport (with the 3.5 Ecoboost) which averaged about 13 L/100km (~18 mpg) for the first 30000km, but after 40000km it was averaging 18L/100km (~13 mpg). No, I didn't expect it to be good on fuel, but considering I thought I was actually taking it slower and easier I didn't expect that significant a drop. All the maintenance was done in a timely manner, so I would suspect it's actually a sign of premature wear.
There were enough problems (telematics/MFT, suspension/sway bars, burnt fuel smells in the cabin, transmission, headlights, electronic quirks (eg. problems with the sensor when starting the car because it didn't sense the car was in park). Of course, it didn't take long for the warranty to expire along with my patience.
