RAM 2019-2020 Cummins CP4 fuel pump recall

[markandkim]

It's about time that RAM did this.

Starting in Janurary, RAM will recall 250,000 RAM heavy duty, cummins equipped trucks and start replacing all of the CP 4 fuel pumps.

I'm sure that this will take years to accomplish.

Ford and Chevy should have a similar recall, but I haven't heard that yet.

I got the following from another forum. Apparently the CP4 pump has been out for a few years. I haven't researched it any further. So I can't verify any of it.
The guy posted this back in May, 2021.

Now the purpose of this thread is to warn anyone that has a diesel truck between the years 2011-2016. This includes Ford, Chevy and Dodge. Most of these trucks have a Bosch CP4 fuel pump. Please look this up, there is a lot on the internet about this pump. This pump was not designed for American vehicles and when it fails, it is a catastrophic engine failure because the metal shavings from the failed pump goes everywhere. Most repairs average $12,000 to $15,000 because they have to clean and replace the entire fuel system. This is were I am at right now. So, if you have one of these trucks, and you plan to tow with it for a long time, I would suggest being proactive and consider replacing this pump. I'm sure replacing it will be ALOT cheaper than replacing the entire system.

Ram installed them in 2019 and 2020 knowing that. They see it was a major mistake. Now they will pay big time for it. It would be too big a recall for ford and chevy to do. They will just have to settle in a lawsuit, which will come.

When I read your post I had to check on my 19 Duramax. Good thing is GM changed to a HP4 pump in 17.

I wonder if GM will follow suit. I recently bought a 2013 Sierra Duramax with the CP4 pump. Many guys have converted to the older CP3 pump. Some have just installed a secondary filter and lift pump.
