the 6.7 has proven to be extremely reliable up to date, problem is people post about issues, not great reliability. The 1% having troubles can be very vocal. Mines got 70k km's and has been trouble free to date.
Very true, and when the cost is 10,500-12,000 to fix a failed CP4.2 injection pump and the manufacturer refusing to cover it under your warranty, it tends to make the head lines.
As stated earlier both GM and VW fix these pump issues without blaming the consumer. Ford highly deserved black eye is for not standing behind there product. We just purchased a new truck with a CP3 injection pump, if we had purchased a truck with a CP4.2 pump it would have been a GM based on these warranty coverage issues.
I would bet that most people that have had a GM CP4.2 pump failure and not even aware that that was the issue. As GM just fixes it and gives in back to the owner "all fixed and ready to go" enjoy!
Given the 6.0 and 6.4 track record, this has not been very smart on Ford's part. Or the failure numbers are higher than we know and it would effect their bottom line more by masking over the problem than p!$$!ng off a small group of customers. Chris
I diesel tech recently reported at FTE that all but 1 HPFP that he replaced had either gas or DEF fluid in the tank and some people expect this should be covered under warranty? Also he stated he replaced one HPFP with no signs of rust on the HPFP or DEF crystals and it was covered under warranty.
GM will now look for any signs of fuel contamination and no they will not just blindly replace a HPFP without inspecting and getting approval from GM warranty.
My cousin has replaced several Ram/cummins CP3 fuel pumps last year due to gas contamination and one that had galvanized steel flakes in the filter in which Chrysler voided the warranty on both accounts. As a matter of fact he doesn't even want to be around the customer when they are notified of the warranty denial and they want to see why it failed.
LOL, another good line of stories, Fish :R
I have read of several CP4 failures in the 6.7L Ford where there was no contamination present (Ricatic`s was one of them if you choose to remember). In the cases where there supposedly was rust contamination present, owners were quite stumped because the water in fuel light never illuminated and they had NO water in the fuel water separator, just like myself on all 3 of my diesel trucks. As a matter of fact the owner of Dieselsite had it happen to his 6.7L Ford and actually developed an aftermarket filtration system in the hopes of preventing it from happening again and to other owners. In these cases the owners felt that the failures should have been covered by warranty and I totally agree with them. There have been several knowledgeable people on these pumps post on various Ford and VW sites that have indicated they are a very fragile design with inadequate lubrication that have relatively high failure rates. It wouldn`t even be so bad if it was only the pump that failed but because the failure trashes the entire fuel system it is catastrophic. I think there will be trucks written off in the future due to this issue because the cost of the repair will exceed the value of the vehicle.
Not to say that a CP3 failure is impossible but they are not nearly as common as you have tried to make out. And if the cases you refer to were in fact contaminated by gas well then that is indeed operator error that I would not expect to be covered by warranty.
