What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWe are pleased to inform you that we have published the updated version of the "Introduction to the New Maserati GranTurismo" on ModisCS+. This update supersedes the previous circular letter MAS003504 and includes additional content related to the new GranCabrio.

This letter outlines important guidelines for the technical management of the new Maserati GranTurismo and GranCabrio. Developed at the Maserati Innovation Lab and manufactured at the Mirafiori Plant in Turin, the GranTurismo and GranCabrio are 100% made in Italy and embody Maserati's "Italian luxury performance" concept. Both models feature the revolutionary Neptune V6 engine in two variants: the Modena version with a 3.0-liter V6 Neptune Twin Turbo delivering 490 hp, and the highperformance Trofeo version based on the same engine, achieving a peak output of 550 hp.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS004781 MCL 25-37 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 MAS004781 MCL 25-37 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 MAS004781 MCL 25-37 cover?
The manufacturer filed it against 5 model years: 2025 Maserati Grancabrio, 2025 Maserati Granturismo, 2024 Maserati Nuova Grancabrio, 2025 Maserati Nuova Grancabrio, 2025 Maserati Nuova Granturismo. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
