Just thought I would start a thread to track the issue I ran into with my 2022 HO 3500. I have noticed it has been doing frequent regens lately and it finally threw a code (P2459). No change in power or drivability. I took the truck into the dealer and the fix that is suggested was a PCM update and replace the rocker arms. Unfortunately, the checkout guy did not have a great understanding of the reason for this and the mechanics were gone so I don't have any additional information on if it is just the rockers or the rocker and lifters or something else. He said the mechanic said the valves were not completely opening. I would be really interested in what test was done to find that out but I haven't run across much information on the internets as to needing new rockers. I have seen some information on the issues with the hydraulic lifters but even that is limited. Parts are on order and should be heading back into the dealership next week. Hopefully to get more info as well.
Here is the background on the truck:
