CP4.2 Owners Club

[bcbender]

Anyone heard any new news for the "Owner's Club"?

I finally was able to read the whole post, I may order some Optilube XPD, Im at 2480mi,, (2 months old) and will be leaving on a cross country trip in June.... I would like to break this pump or get past the 3500 mi mark soon . Anyone changing oil / filters earlier than scheduled? I was thinking about doing both before I leave for MT just for good measure, I buy fuel from the same HV place and have only run the tank dn once but I was in BFE and running empty (winter obviously).

I wouldn't do anything aside from mandatory maintenance.
If it wants to blow up you want to happen it ASAP and not delayed.

I dumped the factory fill and filter at 3000... I'm at 14,900 now and going to change at 15k. then it will be every 9000 or yearly... What ever comes first. I did my front and rear diffs factory fill at 5k, All synthetic. Been running OptiLube since day one... So far so good. Picked up a new work vehicle in the mean time.... 2020 MB Sprinter 2500 4x4 Crew 3.0l diesel. It's got a CP3 pump but I'm still running OptiLube is it as well.

Interesting my 2020 International Dynastar Cummins 6.7L has a CP3, although engine manufactured in 2018. Not sure if Cummins used the CP4 in anything other than Ram spec'd engines.

EDIT: Another point is Cummins max HP/TQ for other than Ram spec'd engines is 360/800.

Cheers, Ron

Thanks Ozy, John recommended to change the oil around 5k, I plan to do both fuel and oil service in June a week or two before I leave as I pull a 44' 16K 5er,... I have no real worries, but just that lingering thought roaming around in my head, ..... mostly since Murphy and I have a close relationship
My hope is to not have any issues, but I don't have my head in the sand... My 04 had many issues over the time I owned it.. but none that left me stranded anywhere, not for long at least.

Yet the percentage of people with pump failures is quite low. How it was handled varied dealer by dealer...same as GM. You are correct that GM did seem to warranty more than Ford did. In fairness though, is it the manufacturer's fault that contaminated fuel was used which caused the failure? I know the owners did nothing in poor faith, but a warranty is to remedy a 'defect in materials or workmanship.'

The manufacture has a responsibility to provide a product that operate in the environment it was sold in. It is a known fact that there are variations of fuel quality and not all suppliers of fuel have the same standards but as long as they meet the set standards the pump should be able to operate in that instance. My 99 went almost 200K before a semi took it out and I never had a fuel injection pump issue, yes it was the hated VP44 and I did replace the lift pump to an AirDog but never an issue with fuel itself. I still but my fuel from the same station brands and if this C4 eats itself then Ram needs to make it right because it is not the owners responsibility to quality check every drop of fuel and should have the expectations that using fuel sourced from reputable suppliers will run in their engines. If the manufacture is going produce a product that requires standards beyond the norm and to claim customer liability then they should supply a fuel quality tester with every truck and put a disclaimer that the truck can only be driven in lab environments and not taken anyplace that may have any contaminates and stop advertising it driving in those environments.

DUMP the Factory GL early on and IMHO go with AMZ/OIL SevereGear as the OE lube is junk.

Yes I plan to........., I ran AMS/OIL exclusively in my 04... Sad thing is I bought all the fluids to do a full truck service at 200k and then sold it!.. So now I have a case of SevereGear 75/90W GL, a case of MTF (NV5600), a 1/2 case of ATF (PS/T-case)..and 3 gallons of ZEREZ G05.... I'll have to see what if anything I can use, return, maybe my local dlr can swap it out for me, I was going to ask the guy I buy from at the Pennzoil auto fair (I am a "vendor" there and go every yr) but sadly it has been canceled again.

This is in response to the 1st quarter announcement they made much earlier in the year. Something is coming down the pipeline finally. What it is is speculation at this point...

Sweet. Maybe they can fix my other mystery issues as well. My CP4 still hasn't caused any issues.. the ECM, EGR and turbo not so much.

That's good news............I wonder what they will be doing................warranty extension would be my guess.

 

[Signal73]

Warranty extension is A piece of paper they can draft in an hours time even with lawyers involved. The first announcement was several months ago. I’m going with it’s taken this long because there is an engineered fix in the works. I guess only time will tell....

 

[AH64ID]

I agree. I simply can’t see them spending the coin on anything else. Even the warranty extension won’t be cheap.

 

[SnoKing]

My guess is they have been talking to Cummins and Bosch a lot about replacing the CP4.2s with CP3s. And deciding who was going to pay for what!

 

[AH64ID]

From an owners stand point it makes sense, but not from the manufacturers standpoint. The majority of those CP4 trucks will make 100K miles, probably closer to the vast majority. If you make 100K then a 150K mile warranty is likely not going to cost too much. There is little reason to do anything other than extend the warranty, which has been the industry norm on faulty components with the failure rate of a CP4.

They are buying piece of mind for the majority of owners, nothing more. Can’t please everyone.

If they extend the warranty, I doubt that it would apply to the entire powertrain

Correct, it would likely just be the CP4.

GM did something similar with injectors 10-15 years ago.

I am no longer in the CP 4 club as we traded in my wife's VW Jetta TDI that the fuel system used on her 2011 car.

VW sent us a letter back in 2016, or so and stated that they VW, had extended the factory warranty to 100,000 miles on any vehicle that used the CP4 fuel pump. This was to the original owner only. In the letter VW stated that this would cover all repair cost to the fuel system on a diesel engine.

All I am saying is there is precedent by other manufactures to provide an extended warranty on the CP4 fuel pump. So, this should be an easy fix for Ram, with little or no cost to FCA in the long run.

Might not help the resale value.

They also ran a 4 year/48,000 mile or 5 year/60k mile warranty (depending on the generation) on vehicles that were modified under the emissions fix. This includes the entire engine and fuel system.
