Maserati filed this with NHTSA as a manufacturer communication dated Mar 5, 2025, received Mar 19, 2025. It names 24 model years (2021–2025). A manufacturer communication 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.

What the bulletin says

Source: NHTSA's summary of the manufacturer's communication

We are pleased to inform you that a new Tutorship process has been defined that will cooperate directly with the suppliers of the main components of Maserati’s cars to promptly intercept potential issues, reducing diagnosis times and providing maximum assistance and know-how for the resolution of our clients’ cases. Through the direct support of professional technicians, the Aftersales Tutorship Team with the supervision of the HQ Blue on Line Team will be able to carry out detailed diagnosis on reports coming from the network. If an intervention on a component under Tutorship is needed (see Tutorship List attached), you will have to create a Blue on Line as a Support Request. It’s important that you accurately follow the instructions that you will receive and do not replace a component without authorization.

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.

What owners reported

Source: NHTSA complaint database

Owners of the 19 model years this bulletin names have filed 19 complaints with NHTSA since 2015.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Quote the number at the service desk. It is what the dealer’s system is keyed on.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Maserati MAS004627 MCL 25-18 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 MAS004627 MCL 25-18 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 MAS004627 MCL 25-18 cover?

The manufacturer filed it against 24 model years: 2024 Maserati Ghibli, 2023 Maserati Ghibli, 2022 Maserati Ghibli, 2021 Maserati Ghibli, 2024 Maserati GranTurismo, 2025 Maserati Grancabrio and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
