Alfa Romeo bulletin S2621000003 REV. A
Alfa Romeo filed this with NHTSA as a service bulletin dated Mar 9, 2026, received Mar 18, 2026, about the power train. It names 19 model years (2017–2026). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Alfa Romeo S2621000003 REV. A 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 S2621000003 REV. A 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 S2621000003 REV. A cover?
The manufacturer filed it against 19 model years: 2026 Alfa Romeo Giulia, 2025 Alfa Romeo Giulia, 2024 Alfa Romeo Giulia, 2023 Alfa Romeo Giulia, 2022 Alfa Romeo Giulia, 2021 Alfa Romeo Giulia and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
