Major Repairs

Any response is going to get bashed. All I can suggest to you is to do just a little research and see what information YOU find. From my research, only 2 manufacturers used the fuel pump that had a much higher rate of failure. From those 2 manufacturers that used that point, one manufacturer accepted responsibility and fixed under warranty, while the other blamed poor quality fuel and shifted responsibility to the user.

For what its worth, I haven't heard of any issues with the most recent changes to the fuel pump.

Diesels have very expensive parts and cost big bucks to repair. The reliability of all are probably pretty good. But it doesn't matter who's is better then who's (and the claims are dubious at best), if your one of the unlucky ones that has a problem, you're in for a big spanking.

Good filters!!!!!

Any newer diesel with emissions is going to cost you money when parts break. It's more complicated and requires specialty tools and knowledge that only a few have. Fuel issues can occur with any new diesel regardless of manufacturers. It's always a gamble, research online and filter through the fake stuff or cheesy complaints that you may see. A lot of times it's the owners neglect or overabuse of the engine that leads to its downfall. On the other side, if you treat your new truck well, watch where you get diesel fuel from, and service the filters more frequently then you should have better luck then some. With a gas job, a lot less worry so hence I have one. Good luck on your search, let us know what truck your really interested in or have bought.

There is good reason for GM to dump the Bosch CP4!

I run a CAT dual filter along with the OEM under hood filter. When it comes time for fuel filter changes the OEM looks about 1/3 as dirty as not having the CAT. Just a cheap precaution for the chance I may get some contaminated fuel.
Other than that and regular maintenance I've had very few minor issues in 5 years of ownership. Even having only 6 injectors compared to Ford and GM's 8, I still wouldn't want to foot the bill for an injector/HPFP repair. Lots more to go wrong with a diesel, but that doesn't mean you'll have more problems, it just means you could.

Your post implies that only Fords are subject to major repairs. That is just plain silly. Of course, any manufacturer can have failures that can be very expensive to repair.

So true. If the various posters think the CP4 fuel pump issues are only with Ford, Google Ram/FCA fuel pump issues. No one is immune to problems.

The Cummins 5.0 also use the Bosch CP4 pumps.

Current Cummins 6.7s have a high rate of water pump failures.

They are all great trucks and they all have there demons.

Just another factor that makes RVing expensive unless you stick with a tent or maybe a tent-trailer. Diesel trucks, motor homes towing cars, fuel costs and #1- depreciation on the RV. We all love the life style but no kidding ourselves about the costs. Whether or not it cost less than hotels, cabins and lodges and restaurants is debatable.

Been there, they all have problems. Good thing about the water pump on the Cummins is it's a cheap part and can be fixed roadside if you have the parts. I didn't last time but will if it happens again. That's one thing that's really appealing to me about the Cummins - when it does have issues the fix is generally cheaper and less labor intensive.

Still torqued me pretty good when it happened, though. :M
