2021 RAM 3500 purchase on hold.

[dieselshadow]

All Cummins equipped trucks have the CP4. 2019-current MY

 

[SnoKing]

Do all 2021 models have the CP4 or just the 3500 models?
Just left the dealer ---did a mock up purchase of a 2021 Big Horn 2500, 8ft bed (they are hard to find to find in a 2020 model) and delivery time is 8 to 10 weeks.
Just wondering.
HJR

2019 forward 2500, 3500, 4500 and 5500.

Not only in the RAM platform, every 6.7 that leaves the Cummins plant has it, no matter for what usage it is. Generator, School bus, boats, whatever...
Cummins trusts this pump.

Kinda like they did the VP-44? We all heard the mea culpa on that one.

However I replacement mine myself for $1065, with free shipping both directions with MWFI.

Not the point. The point is Cummins eventually admitted that wasn't one of their better choices. Comparatively, Cp-3 to CP-4 is like going from a P7100 to a VP-44.

that guy, much like others that have posted about CP4 failure, just joined the same day. I’ve seen them post once then never come back. Smells like trolling to me.

I've noticed that a bit as well.. Newbie joins and posts about a failure then never follows up, ever. If I went through all the hassle to join and verify and such just to post about a failure I'd be sure to keep the forum up to date on the details.

By all means, sign up and call them out.

Far from. I’d take a VP44 any day over a CP4. When the VP fails all you need to do is replace the pump. A CP4 your looking at replacing the whole fuel system. $1500-2500 for a VP44 ..... $10,000 for a CP4.

Thats it! Maybe 95% or more of these are OK until 100,000 miles. What % will fail shortly after warranty period is up? What % will fail by 200,000 miles? If that happens you scrap the truck right? If one of their big selling points is "these diesels can go an easy 500,000 miles" well, I find that doubtful. I like to drive my vehicles 200,000 miles if I buy new. Hell, any old gas engine will go 200,000 these days right? I just find it astonishing that FCA and Cummins engineering can't come up with a better setup so that if they are committed to the CP-4 pump, they then commit to preventing the sequelae resulting from pump failure. If the bean counters think that's "too expensive", well what is your reputation worth? And I also wonder what the resale valute will be for trucks with a CP4 and 150 or 200K miles on them. I would bet a lot less than the relative value of anything prior to 2019. I bet most of the people on this forum don't change their truck when the ashtray is full. You buy them for longevity plus the towing capability. Cummins reliability has always been amazing. Will have to see how this CP4 plays out over the next few years. Maybe it will prove to be robust after all. If so, FCA should be releasing all their data right? They will want the world to know the stats bc it would be great marketing.

To late, they are already failing.

Well we don't know for sure what the percentages of failure are. If there are millions of them out there then even a small % of failures results in a relatively large number of complaints. If there are only a few engines out there of SOB and there are only a few failures, it could be a relatively high % of failure, but the raw number is so low you don't hear about it much and assume it's a good engine when it might really be a POS. And vice versa, as Ozzy and others point out. So unless we know the numbers it's all speculation, but to me it sure looks like a lot of smoke for there not to be a fire.

The current problem is made worst by the fact that no parts are currently available to get the truck back on the road in a timely manner.

Wonder if FCA is supplying parts to states that have Lemon laws quicker than states that don't. All it takes is 30 days in service and it's eligible..

No vaccine available or in the pipeline. After a decade almost, it is unlikely there will be one.
