2020 Ram CP failure

[Undecided1719]

Ok so bought a new 2020 Ram 2500 December 30, 2019. Got 7023 miles with CP4 failure. Guess I should have done better homework.

Can we get more details on how it happened?

 

[MikeXM]

What is the dealer saying? Warrantied or not? Any collateral damage?

Pretty cryptic for your second post, TBH. More detail needed. Was water in fuel light on? What sort of failure, i.e. did it send particles downstream?

While the CP4 is a concern, there hasn't been much of anything verifiable as a pump failure.

So... That was the end of this thread?

We need a dead thread revival

Same guy posted on ramforum. A bit more than posted here, but short on details, for sure. If it's really happening I'd like to know about it, but trolls are out there, too.

cp3 conversion here I come.

The CP4 was a definite concern when I was deciding between '18 and '19. I hate to admit it, but with the glitchy 12" screen, the whole camera, and trailer tech debacle, that turned out to be a bust, at this point I wish I had gone with an '18 leftover. In the end, though, I still believe there are a lot of **** stirrers just claiming theirs blew up, and they might not even own one.

I also assume that in spite of FCA and their short comings, I do have faith in cummins and their product and I doubt they would let their name be tarnished through high pressure pump nonsense. I wouldn’t lose sleep over this as being a genuine problem, or you probably would have heard a hole hell of a lot more complaining from the masses who many of which bought this truck simply because it holds a cummins under the hood.

Read that other thread.

Sounds like a fluke bad pump and Cummins is covering the repairs.

Stuff happens.

Keep ALL your fuel receipts and if you ever drop a pump, take a fuel sample before the dealer touches it.

Hmmm...

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...

Interesting read. The OP of that other thread sates, more then once, that Cummins is picking up the tab. There's no way in HE double-L that he or she is gonna know that. The engines belong to FCA, lock, stock and barrel. If there WAS a quality issue at Cummins, FCA would be dealing with that and those deaalings would be transparent to a Ram customer.

I just noticed this on another forum:

Bosch CP4 High-Pressure Fuel Injection Pump Failure Lawsuit

Our attorneys are evaluating claims that the Bosch CP4 high-pressure fuel injection pump installed on some American made diesel powered cars, trucks, and SUVs is failing prematurely because of a defect. Consumers shouldn’t have to pay for the repair costs, but some manufacturers aren’t honoring...

www.forthepeople.com

In the above link they mention:
Why Is the CP4 Pump Allegedly Failing?
The primary reason the CP4 pump is said to fail is because the pump was not designed for diesel fuel in the United States.

Bosch is a European company, and Europe uses diesel fuel with more sulfur than U.S. diesel fuel. The cleaner, Ultra-Low-Sulfur Diesel used in America does not lubricate the CP4 as well as European diesel, makes it difficult on the CP4’s hydraulic pistons to continue working, according to the experts at Diesel Army.

The CP4 also is said to struggle to supply adequate fuel to the engine under the lower pressure of these more efficient engines. The result is the formation of air bubbles inside the CP4. Air in the pump means that metal rubs against metal, causing accelerated wear. This will eventually cause the CP4 to fail, often around 100,000 miles. Before it fails, metal shavings are produced by the CP4, which travel into the fuel injectors and the fuel lines with catastrophic results.

Not designed for diesel fuel used in the US? This is bizarre, let alone hard to believe. How long has this particular pump been used on these trucks?

2019 was the first year for the CP4 in the Ram/Cummins. Prior to that, all common rail Dodges/Rams from 2003-2018 had the super reliable CP3.

The CP4 is a POS, but those class-actions are typical lawyer speak. As far as cavitation, that is basically a Duradud thing, as Gimmick Motors was too stoopid to run a lift pump, and relied on the CP4 to pull the fuel from the tank. That is unspeakably idiotic.

I call BS on that. Simply not true. Since 2009, Europe uses 10 ppm ULSD. Some countries actually use lower level at 5 ppm and 0 ppm.
Sulfur is not a lubricant by itself. But the process used to reduce the sulfur also reduces the fuel's lubricating properties.
