C, 21-054-24 REV. A and 1 more. It names 2 model years (2024).

Read by machine from the document NHTSA serves (32 pages), read Sep 30, 2026. A part number is shown only where it matches Ram’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 104 complaints with NHTSA since 2015. 13 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
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.
2024 Ram 3500 · Power Train · filed with NHTSA Aug 13, 2025 · ODI 11680515
When truck is in drive and I press the brake to shift to reverse, when I take my foot off the brake truck will go forward before reversing. Dealership says there is no problem with it. I find it to be dangerous
2024 Ram 2500 · Power Train · filed with NHTSA Jun 29, 2025 · ODI 11670093
A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram 21-054-24 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 21-054-24 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does 21-054-24 cover?
The manufacturer filed it against 2 model years: 2024 Ram 2500, 2024 Ram 3500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built 14 Jun 2024 – 4 Sep 2024 — the build date is on the certification label in the driver’s door jamb.
