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.

I was 300 miles from home for work for a week. On day 1, while driving on a residential street, I suddenly got a message on the dash that stated "stop safely now". Seconds later, as I was pulling over by the curb, the truck shut itself down and would not start back up. I had to rent a vehicle (being away from home). On day 3, I tried again and it started. I drove it a block away to the place I was staying. Entering the parking lot, I got the message and it shut down again just as fast. At this point I had to arrange transport of my truck back home. $650 and 3 days later, I finally got it home. Started it, ran for a few minutes parked so tried to drive it. Made it about 1000 feet when it shut down again and left me stranded on the highway. Each time it shut itself down, I had to wait a minimum of 1 hour before it would restart. After researching, it seems that my egt13 sensor has gone bad and has to be replaced. Had it shut down while I was on the interstate, the results of this could have been a whole lot worse than the expense of a rental and transport. My research brought to light that this seems to be an ongoing problem with fords that needs to be addressed and

I have a 2012 ford f350 crew cab 6.7. Miles 72160.6, eng hrs 3877 and eng hrs idel 1700. Which is very low for the egr to go bad and notice there are thousands of ford owners are having the same problem. Which many are bypassing this system. I think its about time someone looks in to this problem with ford manufacture. This way ford owners do not do bypassing the emission systems. I wondered why hwy patrol was pulling over diesel trucks. Looked on line and found out for inspecting them to see if any bypass emission was done on that truck (california). Egr (emission) is just a major headache and this needs to investigated.
