NHTSA Complaint #11680515 — 2024 RAM 3500

Excessive Diesel Exhaust Regeneration. Vehicle in in regeneration about 72% of the time. Check engine light comes on about every 2 weeks with code P2459. The P2459 code indicates an issue with the diesel particulate filter (DPF) regeneration frequency in diesel vehicles. This code is triggered when the powertrain control module (PCM) detects that the DPF regeneration process has not occurred as expected. Have to take to dealership for a manual regeneration and to clear the code. Dealership says this is a known issue for Ram Diesel engines from 2018-2024. Dealership says Ram has yet to address the issue even though its been 7 years since the issue started in the 2018 model year. Been dealing with this for a year now.
