What it saysUnresponsive 4WD Shifter, Service 4WD Light Illuminated. NHTSA’s full summary ↓
Ram filed this with NHTSA as a service bulletin dated Jul 30, 2025, received Aug 6, 2025, about the power train. It names 12 model years (2023–2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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 6 model years this bulletin names have filed 279 complaints with NHTSA since 2015. 34 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.

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
Transmission just started shifting very hard causing the truck to shake. Truck was fine last week, mileage is 9600. Have notified the dealer, they said to bring it it in. There is no warning lights or alerts
2023 Ram 2500 · Power Train · filed with NHTSA Sep 21, 2024 · ODI 11615778
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 S2508000062 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 S2508000062 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 S2508000062 cover?
The manufacturer filed it against 12 model years: 2025 Ram 2500, 2024 Ram 2500, 2023 Ram 2500, 2025 Ram 3500, 2024 Ram 3500, 2023 Ram 3500 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
