Fuel System Failure?

I'm curious if anyone has had a fuel system problem with a 2019 Ram? My brand new 2019 Ram with 245 miles is sitting in the shop, apparently in need of a new motor, due to a catastrophic fuel system failure. Is this problem affecting anyone else? I am told by the mechanic at the dealership that the CP4 fuel pump has apparently failed and the fix is Chrysler FCA sending a new motor. Waiting to hear more on Monday after the dealership contacts the engineers and starts what they referred to as a "STAR" case.

Details, please. Since they are offering warranty repair, I would assume they have ruled out a fuel contamination issue??? I can see where they would have to replace the entire fuel system, which is typical in a CP4 failure, but replacing the engine seems VERY peculiar.

There have been many of us '19 owners who were/are concerned about Cummins going to the CP4, given its very poor past history with GM and Ford. Ram and Cummins have been INSISTING that the pump has been improved, but have not offered a solitary shred of evidence showing what or how it was improved. Thus far the naysayers have been pointing out that there have not been a sudden barrage of failures, which to my knowledge is true, but time will tell as miles are accumulated.

Please be sure to come back and update this thread with any information you can offer.

The mechanic stated he tested the fuel and it was okay. I have no way of knowing the quality of the fuel, it was purchased from a convenience store.

Aside from what the dealer provided in fuel when I bought the truck, this was my first fill up. I also filled the DEF tank with commercially purchased blue DEF.

The mechanic did not speak highly of the CP4, remarking that the CP3 has worked effectively for years on the Ram's.

I will update further after I hear more on Monday. The mechanic and service advisor both believe that the CP4 failed, it's not providing enough fuel pressure.

I have searched the internet and have struggled to find good information as to Ram's either experiencing or not experiencing failures due to fuel system issues. I am looking for information as much as the next person.

Firstly, welcome to the HDRAMS forum. It sux that your brand new truck with a big problem is the reason you're here. Concur with 1HasBeen's comments. If the CP4.2 did fail I can understand FCA replacing all fuel system components downstream of the pump. But the whole engine? Perhaps there is more to this than just a pump failure. A lot of 19 Cummins operators will be watching this thread.

Do you have a 2500 or 3500? Standard or HO Cummins, and which trans? Curious how you fit 2.5 gallons of DEF in a truck with such low miles?

I was hearing a lot of information from the mechanic last night and I have not properly relayed all of it, I remember bits and pieces as someone asks a question. So he bypassed the fuel system and it will start, but smells horid, doesn't run correctly, won't make power, etc., The information which I'm not clear on is whether there is a component that is built into the engine and not replacable or that the CP4 part is not available to dealers and therefore the only fix is a new motor. I will definitely update this thread when I get information from the dealership on Monday. I will ask more questions as well so that I can accurately relay to the forum. At this point I don't know if I am the 1 unlucky guy who got the bad part or whether this is indicative of some engineering failure. I'm cure the mechanic and the engineers will probably have different takes on this.

3500 - standard cummins - not sure which transmission off hand. I don't think I said anything about fitting 2.5 gallson of DEF in the truck, I said I filled the DEF tank, meaning I topped it off

Ok - you got my attention with this thread.
It would be outright foolish for Ram to start using the CP4 without modification and extensive testing. But who knows - very limited info.
@disappointed_owner - I hope they get you fixed up so you can change your username.

I'm sure they'll get it all figured out

This is my fifth Ram; 3 diesels and two gassers, and honestly my very first with any problems, I will probably change my user name, but it gets peoples attention for the moment!

Odd they would replace the entire engine but maybe cheaper than chasing a problem? Could be the only solution until they know what they are dealing with.

Engine replacement isn’t trivial

I agree a complete engine replacement, which I see online retails for $17k, is crazy, hoping to get some clarity on Monday. As I mentioned in a previous comment, the mechanic said either that the part is part of the engine or that it's not available by itself. I'll update everyone tomorrow when I hear back from the service advisor.

It isn't possible to bypass the CP4 and make the truck start. Something is getting lost in translation.

I received a call that the engineers have suggested a different route, there is some type of valve on the motor that actuates the high pressure pump. They've instructed the dealership to try that option first, and have found that part and are shipping it to them. The service advisor was less than convincing in selling me on the fact that this option would solve all the problems. So now it's hurry up and wait 3-4 days.

Generally, when a CP4 fails it sends schrapnel everywhere. In a few minutes, a sharp tech would pull the FCA off the pump and look for debris on the screen. None of this is making sense.DW-1812-LML-06.png

When you go to the dealer please take picks of everything as they can’t deny you of that. As they say a picture is worth a thousand words. It also helps if things go sideways warranty wise. Please post the picks here. They also say the proof is in Christmas pudding....or something like that.

Thank you for the update, @disappointed_owner. If it would be of interest, I would like to get a case opened for you from the customer care side. This will allow us to have your experience formally documented within our system, and it also gives us a chance to connect you with a case specialist who can work alongside your dealer for the rest of the time your truck is in service. Kindly shoot us a PM to get the process started.
