The Jury is still out on it, I'm still tracking the progress since replacing the parts, Here is post parts replacement and currently I have around 240 miles since last regen and gauge is reading like 34%.
It will actually do a passive regen now, before all I would see is the gauge go from 0 to 15 to 25 to 34 to 48 all within around 20 miles and an average of 150 miles between regens then a regen would happen.

Never go to dealer for this issue, even at 100%,run on interstate above 15 hundred rpm,until reads regenerate in progress an dont stop if you can till clears,dealer will charge you over 300$ to do a computer service an if you run on interstate it will clear out,i run diesel additive archoil, an if you buy,start with the system clean 1st,add to nearly empty tank an follow directions on bottle then continue with the treatment on every tank,dont buy EDT,IT SUCKS ,AN will be doing more regens,i soon wont have to worry about this problem cause im doing a performance upgrade to my 6.7,
Goodluck...

You're doing it wrong
Warranty work is free and “just run it” is bad advice. There is clearly an issue and it should be fixed free at the dealer
When my truck was covered under the warranty i to was having this issue an was on the phone with a dealer in Waynesville Georgia and he said that i would have to make a appointment for this issue and it wasn't covered under the warranty, so if your dealership is covering it, post it an i will take it to this dealership and show them an ask them why they stated to me it wasn't covered under the warranty...

I dont have an issue but how can the dealer say its not covered emmisions systems are covered 5years 100k miles
Thats what i was told,so i kept driving an it cleared up on its own an was at a dealership in Tennessee and was talking with another Ram owner about this an he told me just drive an its cleaning as you drive longer than 20 minutes at highway speeds and thats what ive always done,not everyone has the time to be at the dealership just waiting, atleast i dont...
I also do my own services to my truck oil filter an both fuel filters and dont buy them from the dealership either, only thing i let them do is rotate and balance the tires

They have the longest warranty out if all the factory warranties here, the basic warranty pkg on the trucks here is 3years 60k km bumper to bumper/ 5year 100k km powertrain / 5 years 160k km emissions system. I would assume the US is giving the same basic warranty package

I guess the FCA US is indeed different or all the dealers throw that in here? I never looked in the manual that sucks for you guys
Ford and gm have the same dpf info in thier warranty manuals last I checked

I have FCA canada is what i meant… i just checked my warrenty book and yes the DPF is covered here for 5 years 160k km so i guess it is a US thing for hardly any emissions warranty

This problem should absolutely be covered under warranty in my opinion. I looked at the full 32-page Diesel Warranty, which can be downloaded from mopar.com. That says the Basic Limited Warranty is 3 years/36,000 miles. It says (at page 6) the basic warranty covers "all parts and labor needed to repair any item on your vehicle when it left the manufacturing plant that is defective in material, workmanship or factory preparation. There is no list of covered parts since the only exceptions are the parts listed in section 2.1.C." All such repairs are to be made by the dealer at no charge. From my read, per federal law, certain diesel parts also have to be warrantied for 5 years/50,000 miles. Those are expressly listed (as provided by superjoe83 above) at pages 16 & 17. (also attached for reference).
I don't know what listed emission part would be the problem. Seems no doubt, though, that the OP's problem should be covered under warranty - either Basic Limited or the Federal required Emission Warranty. What the 5yr/50,000 "Cummins Diesel Engine Components" covers is at page 8. That doesn't seem to apply, due to what parts are listed as "ONLY" covered. That says nothing about emissions system.

Mine is throwing a p2459 code about every other week, sometimes about a week and a half. It's annoying and concerning.
Less than 65k on the clock, but the previous owner had about one third of the hours in idle.

Didn't want to start a new thread, but am curious to what others have been seeing with their DPF gauge.
I have a 2022, about 19k miles on it. somewhere around 500 engine hours, maybe 90 of which are at idle (use the high idle function mostly). Certainly do my fair share of city driving, but regularly get on the highway for at least 15 miles a few times a week. Tow infrequently as of now.
When I picked up my truck last December, my DPF would read 0% for a looong time, then after short trips go up to about 1/8 for awhile, then 1/4 for awhile etc etc until regen. Pretty much what would be expected.
Now it seems like even after a regen or long highway trips the DPF will only stay at 0% for 1 or 2 short trips, sometimes gets up to 1/8 before I can even get to the interstate from my house (4 miles). Then after a few minutes it goes up to 1/4, and a few minutes later even higher. Regens are probably every 220 miles on avg last time I checked, but it seems like that avg is creeping down to a lower milage. Need to collect some more data. Regens have been taking longer too. I think earlier is was 20 min, now 30-40.
Anyone else experiencing much less 0% time than when brand new?

I have a 2022 with ~10.5k miles. I recently installed a pair of Banks iDash monitors, because I'm especially interested in correlating EGTs + DPF status. I have an SD card I need to pop in as I want to datalog for further analysis. (Yes, I'm nerdy that way). To my point though -- I'm starting to experience the same thing. When I got it, regens were very similar to the 2020 I had and what you're describing, only difference is it's an HO vs SO in the 2020. As time has passed though, the regens are more frequent -- far more frequent than I'd expect. One PID I monitor is miles between regens; my last was 186. I do tow a ~15k 5th wheel with it -- the EGTs are 300+ degrees higher when towing and no surprise, the DPF doesn't really seem to ever go above 0. However, it's our only other vehicle and I use it to run kids around, errands, etc. Those short drives just are not good for these trucks, or at least combined with the tuning in the 2022's. Lots of people, of course, say not to use the truck for short trips and I'd *love* to not, but it's what I have. I should be able to drive around to take care of my personal business without the damn thing filling up within 200-250 miles.
I haven't looked to see if I'm missing that extra sensor on the DPF or SCR (I can't remember where they skipped it, and I didn't get a letter saying that recall was something that applied to me) and I don't even know if that'd matter. I know the damn thing drinks DEF like crazy, even unloaded. You can even smell it in the exhaust.
Once I start getting more data, I'll respond back. We still have at least 2 camping trips planned, one will take us about 1500 total miles when it's done, so I should have some more info at that point. I'm debating asking my dealer to drop the latest software on, see if there are some tuning changes. That could go either way, lol.

Waited a little bit before responding to this thread so I thought I'd share my thoughts.
Previously I owned a 2021 Ram 2500 with the SO, of course, that I bought new. It was a daily driver and tower. It lived in Tennessee and would complete my daily commute of 20 miles. It only ever performed a regen at the 24 engine hour intervals.
I recently upgrade to a 2022 Ram 3500 with the HO. I got orders out to California and this new truck was used to pull a 40ft trailer across the country. During that drive I had zero noted regenerations, over 2000 miles, just a lot of DEF usage. Now that I am out on the west coast my commute with this truck, when I drive it, is 120 miles a day. I have added the banks iDash to monitor miles between regeneration and I am currently averaging 414 miles between.
This doesn't seem to bad compared to others but it is definitely happening more often than my 21. My 22 is missing the one sensor from the DPF filter.
Personally I believe the HO's are tuned and ran so much more differently than the SO that when you run around unloaded they really don't like it. Compound that with the fact that these filters do have life expectancy and its a recipe for future issues as the miles climb.
To help slow the issues I might have by dallying the truck I have a Jeep 4xE that I now drive most of the time when I don't need to pull the trailer.

Great response, thanks.I have a 2022 with ~10.5k miles. I recently installed a pair of Banks iDash monitors, because I'm especially interested in correlating EGTs + DPF status.

Im 100% with you on the short trips. I dont have the luxury to own both an expensive '22 truck AND a gas burning errand hopper. I did sell my TJ recently and I do regret that...but that's another topic.
I'll have to check my sensor too. I remember there being that letter saying there would be a recall, but I assumed your DPF would always read 0 if that was the case. I need to slide underneath the truck and look, someone posted a thread a while ago on there the sensor is located and how to tell if you have it or not.
Bottom line, hope this trend doesn't continue to the point that i get the freq regen CEL or some costly DPF repair not covered under warranty. I plan to keep this truck for 10+ years, but less than a year in the stats don't support that goal!
