Good news Cp4 to Cp3

[Bob4x4]

It’s official if your 2019,2020 Cp4 fails Under warranty FCA will be replacing it with a Cp3 retro fit kit.Of course it will include a new calibration.This info is new so I have no clue yet what the availability time line is yet.
I imagine that will mean there will be a change on the production line at some point.

Is this April Fools??? I guess that tells the tale on the CP4, and how it was "necessary".

And if it doesn't fail while in warranty I am stuck with it??

They should just do a recall and get it over with. Wont happen of course, but at least then they wouldn't have to change out all of the contaminated parts, and the owner wouldn't have to be stranded out on the road somewhere.
oh yeah, and the "they's" need to fire the person who okayed the CP4.2 in the first place.

Ya think they had more than just a few failures?

Probably made a deal with Bosch to fix the mistake "that Bosch talked them into" for the 2019+ models.
Step 1. Fix the broken ones with a CP3
Step 2. Would be to replace them all before failure.

NO ONE is going to want to own a white elephant that has low resell because of a CP4-2 IP. I wonder, once this gets rolling if they will reimburse people that do the conversion themselves?

Perhaps they'll have enough failures on trucks that are under 36k miles that they would just recall all that are still under FCA warranty for a replacement (3/36 or MaxCare). But then I guess that all the out of warranty CP4 owners will sue FCA. Rob S is right though, It would be a smart move cost wise to replace "good" pumps before possible failure as the additional man hours AND parts required for a failed pump repair is substantially more than installing just the retrofit cp3 kit. We shall see... Just depends on how many failures occur, I've only heard of 2 so far.........................

The Cp4 used by FCA has asymmetrical lobes that cause nvh.the Cp 3 replacement has symmetrical lobes less nvh.This is the reason given for the change.No admission of failures.

Once again im reminded it's best to give a "brand new" product time to be proven before purchasing.

Wow I wonder what lawyer thought THAT up...I'll bet (s)he gets a bonus !!!!

Yes, of course, NVH was my first thought.

No one knows how a CP3 that is designed to maintain 23K psi performs in an application that demands 30K psi.

I’m betting Bosch knows!

Absolutely, but they want tell this to the public right?

When reading through your text I first wondered if it wasn't for a parts shortage due to Covid, but it seems much bigger than that. If indeed they move forward this is quite unprecedented changing the production clock back...

I'd love to be a fly on the wall in those meetings!

It ran 26K psi on the 6.7. I don’t recall any crazy changes to it’s design for that.

Wonder what pump will be on the 2021's???? Work on it, if it is changing, would already be complete. How many class actions does it take? Ford seems to have several and VW?

How is the Denso pump on the 2017+ Duramax doing for GM?
