Good news Cp4 to Cp3

[DonFitzwater]

I got put on vacation for less than that.

I must be the teacher' pet! If it's any consolation, I got kicked off of Youtube!

I got a 7 day jail term from the Kangaroo fact checkers at Nazi book last week. I could not leave my opinion. Hurt someones feelings. Done with FB.

no dictators here, just be forewarned some fellow members report everything related to politics that shows up in the truck threads. I'll just take it as side sarcasm and move on.

The CP4 'revision' ..... is it reported to be working or still failing? Inquiring mind as a 2021 truck could be on my radar now that the 12 valver is hitting 409,000 miles, and all the Dodge parts are failing haha

2021's are CP3s so nothing to worry about there.

I hope more and more people realize this is the only real path forward.

So far my new 2020 2500 Ram built with the updated "One Dot" CP4 with 67 days and 1,537.8 miles made it home and several other places without any surprises. I, too, agree with DonFitzwater's attitude with every trip. (Hopefully no scary jinx with this notification of short positive experience)
Only had one odd experience where the adaptive cruise control sensed a very dark angled shadow of an overpass on I-5 as an obstacle and slowed down "very" quickly, then briefly braked strong. I initially thought dead engine as I began to pull over. The braking and ding (!BRAKE!) gave it away and the truck regained throttle response as the shadow angle changed and passed. Technology is...so "exciting" sometimes.

got rid of my satellite couple months ago. much happier, and have a little extra pocket change too. congrats on dumping fakebook. cheers!

If you are concerned you better install a CP3 conversion kit.
Goes for around 2700$ all in all.

I'd give that a thought if FCA would continue the 100k warranty. Thats why I was "wishful thinking" they might offer a "CP3 upgrade kit for us 19-20 folks at a split cost, if the current CP4 was not toast at that time. It could save/make them money instead of a blown CP4 with metal throughout the fuel system at a 10K cost I read..

I really think the best approach is to run right up to the end of warranty the pay out of pocket for the CP3 retrofit kit.

I saw someone reported on FB that a revised CP4 failed. Don't know any more details beyond that but heard another post on the thread the same. The revised pump wasn't on long so I doubt the numbers were good enough otherwise they would have kept the cheaper pump.

I've had mine for 3 weeks, 1000 miles now... Going to start towing my GN trailer around to finish the breakin. I too hope to be a lucky one but its kinda like playing the Powerball. I hope that if failures continue to grow, FCA will allow a retrofit kit to be installed w/o warranty issues, I have the 8/125 maxcare, so gonna let it ride otherwise and hope for the best. Does anyone know the actual failure rate of the CP4 and CP4-2 as related to total volume?

FCA, Bosch and Cummins are prob the only ones that know. Currently there is no legal requirement to breakdown the number of occurrences in failures like this and there is no benefit to any company for doing so (oversell your positives, downplay your negatives).

I don't think knowing the actual failure rate really even matters. A revision and a switch back to the more expensive CP3 tells you all you need to know. I've said before on other sites that I fully expect there to be a TSB/recall on these or a FCA specific lawsuit. Make your changes before then at your own risk but really at the end of the day there are only 2 main issues I've seen on these engines so far. #1 far and away is the CP4 giving up. #2 is a small handful of engines seizing due to not using the correct oil weights for the new hydraulic lifters. All the other "new" tech is pretty well known and I think it's pretty unlikely we see anything else fail.

So said another way. Assuming you're using the correct oil for your engine, and you swap the CP3, the only thing you really need to worry about would be a QC issue or manufacturing problem resulting in something totally crazy happening. I'd imagine even if it did assuming all you had done was the CP3 conversion you'd find a dealer willing to take care of you. I'm not a lawyer.

I would also pay a shop with ASE certified mechanics to do any CP3 conversion even though I could do it myself. Easier to defend in court if they try to claim some other failure was caused by the conversion. Of course that only matters if you haven't run out your existing warranties.

So I came across this little blurb on another forum I frequent. Ram social media team is active on there, addressing concerns of customers. One of the reps posted this in response to one of the long running CP4 gloom and doom threads over there. Should be interesting to see what they are proposing....

“Hello everyone, we would like to relay the latest update to you here regarding your concerns with the CP4 pump. There is currently a service solution in progress for all 2019- 2020MY vehicles equipped with CP4 high pressure pump. Further updates will be announced here as soon as more information becomes available. In the meantime, please know that our team remains available to assist in resolving serviceable vehicle concerns via private messages. Thank you,

That's great, thanks for sharing.

Yes.. thank you for sharing!...

Bosch must have been emboldened by Ford's continued acceptance of the CP4.2 failure rate to even think about selling them to Cummins for the 6.7. This is more a Bosch/Cummins issue than a RAM issue. A solution for the 2019/2020 CP4.2 pumped trucks will come with Bosch/Cummins stepping up to the plate. If RAM decides to put an Iveco or other European diesel in the RAM, at this juncture it will be Cummins own fault.

I'd take it.

Non EGR and 50k miles oil change interval.

I just posted that on TDR before seeing you had it posted....Great news. Got mine from the HD RAM board .

Everything that I've heard is that Cummins didn't spec the CP4, FCA did. That line of thinking makes sense as Cummins still includes the CP3 in their own crate engine 6.7.
