I have 18 ford trucks all diesel 1997 up to 2016 all with dealer maintenance , oil and fuel filter changes every 2,500 to 3,000 miles . Dealer just did a reflash of my truck per a recall and oil change at 15,000 miles because I'm getting into my busy season and just didn't have time to bring in the fall for its regular service interval . Long story short 50 to 100 miles later driving the truck the other morning and it goes into regen and before it finishes the motor starts to rap . Had it towed to my ford dealer and they informed me it siezed and the motor was junk and my warranty was up in May of 2016 ? They told me it was going to be around 20K for a new motor unless Ford could see if it a castostrofic failure. Anyone with the same or similar problem I'm looking for advice or help .
