While traveling at highway speeds on the interstate the engine began to rapidly loose power. The warning light showed "reducing power". the truck quickly lost power but I was able to move it from the travel lanes as the engine completely shut down and I lost power steering and power brake functions. The truck was towed to a authorized Ford dealer where it was determined that due to "contamination" in the fuel supply the fuel regulator stuck open and the engine shut down to prevent further damage. Upon visual inspection by me at the dealership I examined the metal portion of the fuel regulator which had rust like corrosion on it due to moisture in the fuel. Ford's position is that the moisture in the diesel fuel is "contamination" and therefore caused the problem. The system has two in line filters one of which is specifically designed to separate water from the fuel because diesel fuel has a certain moisture content in it. Ford will not warranty the repair and is recommending a complete replacement of the fuel system or the remaining warranty will be voided. The repair is estimated to be in the $10,000 to $12,000 range. My understanding is that Ford(as well as other automakers that use the Bosch fuel systems) has many complaints related to fragility of this diesel fuel system and that it was recommended to me to file a complaint with the NHTSA. I am able to provide more specific details as required. Please contact me with any questions.

The def tank continues to throw a check engine light warning. According to the dealer Ford knows about the problem and there is no current fix to the issue. My def tank was replaced with a unit off another vehicle on the lot and was told that I could be left stranded if the light continues to stay on. San tan Ford had no fix for the problem until Ford release a fix and according to the service manager there are 120 people waiting for tanks. How can Ford continue to sell these F250's if the def tanks are not working and leave the vehicle out of working order. This is a serious safety issue if the vehicle disables itself at anytime due to this problem! there needs to be some pressure put on Ford to get these vehicles in working order and people should be made aware of this problem if they are spending over $50,000 on a new vehicle that may at anytime stop working with no fix available. Need to recall asap, people all over the forums are complaining of the issue and removing these pollution equipment to have their vehicles working correctly. Not good business Ford!
