I loved the truck, good mileage, averaged 12-13 l/100 km, with 9l /100 km on highway with no load. It had great power and towed effortlessly. This past fall, heading north we drove some 18 hours in wet rainy weather. I pulled out to pass a truck, hit the gas and the engine died, missing badly, check engine light flashing. Long story short, it was a known problem with moisture in the charge air cooler for the turbos. When heavy acceleration, water was sucked into the motor. A TSB indicated a partial cover for the CAC, and re flash the ECM. Very shortly after that, at 100,000 kms, a noise developed in the motor when initial startup. I checked the web again, and found several issues in 2011's with stretched timing chains and worn gears. Well, after reading many TSB's and guys on the Ford Forums with similar issues, I traded her in on a 2014 5litre. My average mileage with the new 5 litre is the same as my Eco boost. My dealer was excellent to work with through all this.....so....do your DD.
