That’s a pretty debatable standpoint."If" there were a major problem such as this, I would hope that RAM would have issued a recall by now.
Track records speak volumes, and from where I stand, I think their track record is lackluster.

100%In my opinion, manufacturers weigh the cost of fixing an issue against the potential loss in revenue. Their goal is to turn a profit, which doesn’t always align with doing what’s ethically right. Recalls are typically driven by safety concerns, so unless an issue poses a clear safety risk or pressure comes from NHTSA they’re unlikely to voluntarily issue one. And this isn’t unique to Ram. Ford, GM, and pretty much every manufacturer take a similar approach. No brand is universally better each has its strengths and weaknesses. At the end of the day it comes down to picking your poison. Currently I'm drinking the Ram cocktail.
Ford CP4 pump and transmission issues are the main reasons I’m walking away. The truck has a lot of great qualities but either of these problems alone can leave you stranded. My first transmission was replaced at 13k miles, and now the second is already showing the same shifting issues just a few hundred miles later. Now at 50k. A TCM update helped somewhat, but the clutch packs were damaged and now that I’m out of warranty they won’t replace it again. The 8-speed transmission and new CP8 pump give me some optimism if they can work through the minor electrical issues, and it feels like they’ve got a solid product while working through the learning curve with the Atlantis architecture, especially since the Ram 1500 went through similar early growing pains and is now a stable platform, so there’s reason to be hopeful.100%
Ford still using the CP-4 HPFP to this day, despite a significant number of failures.

Nice. Wonder if removing the fuel pump fuse(s) would be better move as it doesn't reset everything pulling battery terminals. Easier too. Then again - I think pulling power away from pumps is to prevent inadvertently pumping fuel into fuel canister while open or losing prime from pump to canister.UPDATE: I just completed my FIRST fuel filter change on the 2025 Ram 2500---100% success--it started IMMEDIATELY/No Check Engine Light/Engine runs very smooth.
Here are the steps i followed:
1. Remove battery cables/high pressure air to blow off any dust on and around fuel canisters
2. Removed 1 canister lid at a time (so no contaminates could fall in one while I was working on the other)--lid was hard to turn with rachet.
3. Removed old filter--see fuel filter 1 picture below. (easy to remove)
4. Installed new filter--filled canister full of fuel using small funnel--see fuel filter 2 below.
5. New O ring on lid and installed
6. Reconnected battery cables
7. I turned ignition to run position 5 or 6 times--I DID NOT TRY TO START IT. (was getting late in evening)
8. I let truck sit overnight (to allow new filters to fully "soak")
9. Did the same process of turning ignition to run only 5-6 times this morning
10. Then put foot on brake--truck started IMMEDIATELY (started the exact same as it always does)
*Maybe this post will help someone*
They want the batteries pulled so that the person changing the filters doesn’t inadvertently trigger a fuel priming sequence by opening the driver door. That’s how they’re programmed now. Used to be programmed to prime on pre-start ignition on. Now they do it sooner.Nice.

Loved the one can at a time to prevent debri dropping into open can. Excellent tip.
You just saved, or paid yourself, ~$400 by doing it yourself over dealer!![]()
Yes. That is why I said maybe pull fuse instead of battery. Both do the same function.They want the batteries pulled so that the person changing the filters doesn’t inadvertently trigger a fuel priming sequence by opening the driver door.

mbarber,Updated TSB as of 2/19/2026 on this issue. There’s an update available that addresses the longer crank times, as well as a host of other malfunctions / errors. They’re changing the pump prime sequence to run longer / harder in order to help purge the air out. View attachment 93902

While im sure this will help, this is still a bandaid.mbarber,
Excellent! Thank you for posting--we are learning together!
If the supply and discharge are at the bottom, which I believe is the case, it would require a whole new housing, or a blead screw on top which is a band-aid IMO. Software update is also a band-aid. Just a poorly thought out design. I can't believe this was a Cummins engineer. Me thinks - Ram. LOLWhile im sure this will help, this is still a bandaid.
They need to get the redesigned lid / housing out so that it isn’t trapping air at all.
It will be a new lid design with automatic air our purge valves for what I hear…If the supply and discharge are at the bottom, which I believe is the case, it would require a whole new housing, or a blead screw on top which is a band-aid IMO.

I highly doubt that. Creates a failure point and possible fuel spill to atmosphere. We shall see.It will be a new lid design with automatic air our purge valves for what I hear…
Probably at the bottom of his engineering class.

Well that’s right from the horses mouth so…I highly doubt that. Creates a failure point and possible fuel spill to atmosphere. We shall see.
