Read by machine from the document NHTSA serves (2 pages), read Sep 29, 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.

Purchased the truck new with 25 miles on it from the dealer. Within the first 2000 miles, I had a message pop up that said "Service Exhaust System See Dealer". I took it in to the dealer, they said it showed a random emission related code had popped up but was not currently active, so their recommendation was to clear it and see if it…

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram S2523000055 REV. C 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 S2523000055 REV. C 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.
Which vehicles does S2523000055 REV. C cover?
The manufacturer filed it against 2 model years: 2026 Ram 3500, 2025 Ram 3500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
