There is a recall for certain Ford super duty trucks NHTSAV- 457. Dealer will reprogram for free. Letters should be mailed out 1-13-2025. My 2022 F450 is under this recall. This involves the fuel pump. You can call 866-436-7332 for more info.

It would be interesting to see Ford's rational. Is it if they make a change now the lawsuits will comeWhy Ford continues to use this pump in their diesel trucks is beyond me. Of the big 3, they are the only ones still using it. Just that alone would keep me from purchasing one....
Expensive lawyers will always win over regular people in a courtroom.I also do not understand how Ford has not lost CP4 lawsuits. I know money and lawyers but what are the details?
So now I gotta ask....how did you come out after suing GM?FWIW Ford's CP4 allegedly has an additional coating (teflon like) on the tappet and roller which were the failure points on RAM and GM. The amount of failures for each have never been disclosed but is perceived to be less than RAM (the highest) and GM (next). GM settled a class action for $35M mid-2024. RAM recalled their CP4s and replaced them with a modded CP3.
I sued GM once due to complete brake failure causing me to rear-end a tractor trailer. GM sent a team of five high powered attorneys from Minneapolis who only dealt with GM brake lawsuits. They weren't cheap I can guarantee you.
CP4 affected parts were coated with Teflon around 2020-2021. Pressure was increased from 30ksi to 39ksi (per copilot) in 2020. Big change and how did that affect reliability? Should be more energy efficient and possibly better emissions. Sounds like it could be more heavily loaded (psi, unless roller contact area was increased, but see below reduction in load). Also does not sound like something a company would readily do if they were very fearful of excessive failures, they need to compete, or they are delusional.FWIW Ford's CP4 allegedly has an additional coating (teflon like) on the tappet and roller which were the failure points on RAM and GM.

The CP4.2 was failing on the RAMs as well (2019-2020). There were two versions of 4.2 on a RAM - early and late but both still failed - the piston would rotate 90 degrees and shards of metal would follow. Bosch claimed it was bad fuel, bio-diesel, running out of fuel, etc. I was really glad for the recall and replacement. Mileage went up (3mpg hwy no load), less DPF regens with trailer, easier starting, smoother shifting on the Aisin (there was also a flash for this). The Cummins replacement HPFP was CP-ISB21 which was built along the lines of the CP3 but with 20% higher fuel pressure than the 4.2.News to me and huge: Bosch CP4 fuel pump has undergone some redesigns to address issues related to piston rotation. Specifically, the CP4.2 (mid 2020) variant introduced a symmetrical cam lobe and a keyway to prevent the roller bearing from rotating, which helps keep the piston properly oriented. This change was made to reduce the aggressive ramp rate of the cam lobe, which was believed to contribute to lifter failure in earlier versions.
Rotation was a key problem with the pump and Ford would not pay patent owner for a fix--if I remember correctly.
