Summary: We purchased a brand new 60000 dollar truck in 2012 or 2013 and was assured by the dealer that it had a warranty to cover any issues until either 100,000 miles or 5-6 years, whichever came first. After 4 years of ownership and around 67,000 miles, the truck started experiencing problems with a high idle and then abruptly shutting off. When taken to the dealer, they couldn't replicate the issues during a brief evaluation. However, a week later, while on the way to the bank, to get cash out for are stay at the hospital to give birth to are 6th child the truck shut off and wouldn't start again. The dealer diagnosed the problem as a faulty high-pressure fuel pump due to water in the fuel and tried to charge the author $15,000 for repairs. The author questioned why the diesel fuel water separator and the second fuel filter system on the truck didn't catch the issue earlier and criticized the dealer for their negligence in ensuring safe and reliable transportation.

Exhaust manifold stud broke causing leak in exhaust manifold. See the federal safety agency Notice SSM 50330 for a full description of the problem. This notice covered ALL Super Duty pickups from the F250 through the F550 from 2011 through 2014. Ford also noted the problem in a Customer Satisfaction Program letter, #17M05, dated 5 December 2017 but it was limited to the F450 and F550 models. My vehicle is an F350 ... Nevertheless, these models all use the SAME 6.7L diesel engine and would have the potential for the same issue. I have contacted Ford HQ about this. Theystate I must go through the federal safety agency at this point. My Ford Case File Number is CAS44584909. It may be just me, but I consider an exhaust leak under the hood to be a life-safety issue due to the potential for exhaust gases, especially CO, to leak into the cab of the vehicle. I didn't know what the issue was in July, but I had it inspected and repaired at my Ford dealer when I got home in August. That is when I discovered the extent of the situation. $40.12 of the attached invoice is for routine maintenance ... The balance is for the repairs necessary for the exhaust manifold leak. ($3,750.53)
