The failures are real. At one time I read the govt. statistics on them. There was/is some sort of investigation. At that time, GM had about twice the failure rate as ford reported. (it is a very small percentage of trucks)
But there may be some discrpancy in the failures reported as Ford was taking a hard line stance, and refusing warranty on many of them. GM was taking care of the customers, and fixing the trucks, then reporting it. If the warranty denials from ford were included, then the failure rate would likely be pretty much the same for both of them.
I have a 2011, 60K, no problems
Oh, I know they are real. Not denying that. Just stating that statistics gathered from a forum do not represent real world. I to believe failure rates are relatively low but its the price tag that comes with it if you happen to be out of warranty and why its gotten so much attention. If one is not willing/wanting to do a CP3 swap (not cheap) the next best thing is to try to help the CP4 out. A lift pump to supply positive pressure to the CP4 with added filtration along with a fuel additive for lube and you'll "likely" have no issues.
