I have always liked Ford. I have owned several 3/4 and 1 ton Ford trucks. With that being said, I bought a new 2010 Ford F350 CC 4x4 DRW in late 2009. After 11 months and 32K miles the HPFP went out and left me stranded with no prior indications. After having it towed to the dealer I purchased it from, I was speaking with the service manager about the possible problem. During the conversation, he kept saying "if warranty covers it"... After the third time he said that, I stopped him and asked "why in the world would warranty not cover it?". He told me that Ford requires them to sump your fuel and if there is any water in it, your warranty is voided and your insurance will have to foot the bill. I almost lost it! I told him I can not check the diesel that is sold to me from fueling stations prior to putting it in my truck! Furthermore, Ford diesels come with a water separator that should nullify any water in the fuel problems. If this water separator does not work, it also should still be under factory warranty. He said if you read in the front of your owners manual, it clearly states that Ford will void your warranty should any water be found in your fuel! (I did not have time to verify this, I drove straight from the Ford dealership to the Dodge dealership after the truck was repaired!)
After a couple of days, he called me back and said that it was the HPFP that went bad and spread metal shavings all throughout the fuel system. They would have to replace the HPFP, 7 of the 8 injectors, the fuel lines and flush the tank. He said the fuel sump came out in my favor and warranty would be covering the work. Otherwise it was going to be $11K-$12K repair.
While my truck was in the shop for two weeks getting repaired, I traded it in on a new Dodge. Not to say that I wont have similar issues... I just could not stomach the thought of paying $50K for a new truck and $4500 for the 100K mile extended bumper to bumper warranty, only to have it voided by something beyond my control!
Lesson learned: If your Ford has any fuel problems, crawl under it and purge the fuel water separator! lol
