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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS004673 DS 25-09 a recall?
No. A manufacturer communication 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 MAS004673 DS 25-09 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 MAS004673 DS 25-09 cover?
The manufacturer filed it against 9 model years: 2024 Maserati GranTurismo, 2025 Maserati Grancabrio, 2024 Maserati Grancabrio, 2025 Maserati Granturismo, 2023 Maserati Granturismo, 2024 Maserati Nuova Grancabrio and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
