Ram filed this with NHTSA as a service bulletin dated Nov 7, 2025, received Nov 13, 2025, about the electrical system. It names 18 model years (2016–2024). 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.

Read by machine from the document NHTSA serves (2 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 18 model years this bulletin names have filed 6,149 complaints with NHTSA since 2015. 1,059 of them name Electrical System — 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.
On the 2018 Ram 2500, the 29 owners who gave an odometer reading for Electrical System reported it at a median of 37,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I was notified of the Particulate Matter (PM) Sensor not being installed in the exhaust aftertreatment system of my vehicle on a post delivery survey I received. The dealership's service department has no idea about this sensor not being installed by the factory, and the response from the letter stated there would be a recall soon to…

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 S2503000004 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 S2503000004 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 S2503000004 cover?
The manufacturer filed it against 18 model years: 2024 Ram 2500, 2023 Ram 2500, 2022 Ram 2500, 2021 Ram 2500, 2020 Ram 2500, 2019 Ram 2500 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
