I bought this truck in July of 08, to replace my 89 dodge cummins, one of first on the road, and I still have own it. After purchase I took this to Tennessee and back from Arizona. Exhaust only cleaned maybe twice on the whole trip. Took it in to have it serviced and Dealer left the oil fill cap off, oil everywhere. They turned it in to Ford as warranty work when I made them re-service and clean up the mess. The second time I had it serviced when I got home it was leaking coolant, needed new radiator. They said it should be covered under warranty! Idiots. after they replaced the radiator the truck now goes into exhaust filter cleaning mode just driving across town. I haven't changed driving habits, they just changed the programming. I don't have to look to see its cleaning it drags the engine down. It also has something blowing up into the bed behind the cab, looks like diesel from the stain but can't tell. nothing underneath just in the bed, with blowback to the tailgate. I have an 08 Hybrid Escape that they were supposed to service, when I got home I checked the oil it looked black just like it did when I took it in. I am really getting tired of driving Fords.
