Alfa Romeo bulletin 08-394-25 REV. A
Alfa Romeo filed this with NHTSA as a service bulletin dated Dec 12, 2025, received Dec 11, 2025, about the electrical system — 2 documents under this number: 08-394-25. It names 19 model years (2019–2026). 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.

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 08-394-25 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 08-394-25 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.

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.
