1 Other Fuel System Tank Assembly problem

Failure Date: 05/15/2016

While driving the vehicle on the expressway in michigan, it suddenly began losing power. After frequently stopping and restarting the engine, the truck stopped completely. When the dealership investigated the cause, they found specks of paint in the diesel fuel. When the factory installed gas tank was dropped, it was discovered that the coating inside the fuel tank was flaking off and had plugged the fuel filters, contaminated the fuel as well as damaging 3 inverters. . When investigating if others have same complaint, we found many others have had the same problem. Luckily we were not pulling our RV.

2 Other Fuel System Tank Assembly problem

Failure Date: 01/04/2016

Have had this vehicle for 5 years. Bought used from a dealer. Have had problems with it from day 1. Recently, today as matter of fact, driving down the highway, cannot accelerate above 40 mph. This is the 3rd time in just as many weeks that this truck has had to be towed to a certified mechanic. The mechanic has run all or any problems through a state of the art code reader, every time coming up with no code. After many discussions and guesses, we both started to wonder if the Ford dealership found a way to bypass the on board diagnostics finding it odd that every time it was scanned no codes came up. Today it was determined that there is a faulty fuel tank due to delamination. Now why in the world does that not show up in any of the scans related to fuel system problems. These faulty tanks are not covered under any warranty, all out of pocket. Which just led to replacing not only the fuel tank, but the fuel filters, the fuel injectors, all fuel lines, luckily not the engine itself. I have owned Fords my entire adult life. 4 of them being diesels, and all of them being the 6. 0l shame on me for being fooled that many times. But how are they able to always get away with getting around the problem. It is fact that there is a problem with the fuel system in these particular models, and it is proven in every invoice for a major repair related to this fuel related problem in all 6. 0l. The service manager at the Ford dealership always told me "you got the bad egg in that batch". I still haven't seen 1 6. 0l that has not had this problem. Are we wrong for saying this needs to be investigated and action taken for having to spend thousands sometimes more then once to fix an obvious defect on the manufactures end? curious minds would like to know. Thank you for your time and hopefully considering looking into this farther.
