Longevity of the detuned 6.7 Powerstroke

What I can't believe is the fact that Bosch has not had a "Class Action" brought against them yet! This is not a Ford or Gm or FCA problem it is ANY vehicle that is running this pump! The common denominator is the a defective or design flaw from Bosch and they should be on the hook for each and every one of these time bombs.

NO SINGLE PUMP SHOULD HAVE THE CAPACITY OF CAUSING $10,000 OF DAMAGE TO YOUR VEHICLE. it's unacceptable, no matter what logo is on the tailgate. From what I have read, at least GM is standing behind their diesel. If Ford has a failure and they find a spec of rust anywhere in the fuel system they deny warranty. Time will tell how the other manufacturers respond.

x2. Well said.

And as much as some of the failures are certainly related to contaminated fuel or lack of maintenance MANY of them aren't. And even if one does get a tank of poor quality fuel I agree that it should not cause $10k plus in engine damage. Bottom line is that it is a "fragile" pump as described by Bosch that causes catastrophic damage when it fails.

Nit common, but not unheard of. Heet is an example of a product to remove water from gasoline. It happens. You won't know until you have a problem.

like I said prior, I owned a 2011 which was the one everyone complained about, put over 100k miles and never had any issues but I am religious about changing my filters.

Yes, there are those that have had pump issues and were denied warranty by ford as ford stated they had bad fuel or didn't change the filters/dump the separator.

Like I said I have yet to experience it personally, but I go by the schedules and leave my truck as it was when it left the factory.

I dont see why any manufacturer should warrantee damage from the owner using improper fluids, that includes contaminated fuel.

As a consumer I would have to ask how common contaminated fuel is and am I likely to know in advance that it is contaminated. If this problem is at all common and/or I would have no way of knowing that I was getting bad fuel then I would be very disappointed to get $10,000 repair bill and probably a ruined trip on random occasions. Granted, the manufacturers can't cover every contingency but they have some obligation to prepare for the more common ones.

I have to agree with some of the others here that for whatever reason there seems to be less complaints as more trucks hit the road and miles accumulate on the older trucks so it does seem like maybe it was just a startup bug. The point that some pumps have a much less catestrophic failure mode than others is a strong arguement to change pump designs. I have to confess that the fear of pump failure did affect my decision not to buy a diesel in my new truck. I will probably not consider a diesel until I know that the issue has been resolved or at least the cost of repair has been greatly reduced.

You'll only hear the stories about fords 6.7 fuel pump doom and gloom from ram owners, they apparently have the incite on how long the they last. My previous 2011 went over 100k miles with no issues on pure luck...im sure the one on my new ford will implode any minute.

Uh, OK the problem doesn't exist :R

it does exist, but its also nowhere as widespread as you make it out to be. the 99% of the people out there with no issues aren't posting about everything functioning properly - the ones that fail do.

My Ecodiesel is running the CP/4.2 pump and from what I could find these pumps are not having any issues. The main concern as pointed out earlier is the CP/3 pump does not take out the entire fuel system when it goes sideways. The same can not be said of the CP/4 and CP/4.2 pumps.

I can understand why you feel a manufacturer shouldn't be required to cover damage from contaminated fuel but I on the other hand if they were required to cover the damage they would likely install a filter or other such device that would prevent fluid other than diesel from reaching the pump.
