Ram bulletin S1623000028 Rev.
Ram filed this with NHTSA as a service bulletin dated Jun 12, 2026, received Apr 6, 2020, about the structure — 9 documents under this number: S1623000028 Rev. K, S1623000028 REV. J, S1623000028 REV. I, S1623000028 REV. H and more. It names 66 model years (2016–2026).

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ram S1623000028 Rev. 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 S1623000028 Rev. 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 S1623000028 Rev. cover?
The manufacturer filed it against 66 model years: 2026 Ram 1500, 2025 Ram 1500, 2024 Ram 1500, 2023 Ram 1500, 2022 Ram 1500, 2021 Ram 1500 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
