Maserati filed this with NHTSA as a manufacturer communication dated Oct 31, 2025. It names 56 model years (2016–2026). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS004918 MTB 25-39 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 MAS004918 MTB 25-39 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 MAS004918 MTB 25-39 cover?
The manufacturer filed it against 56 model years: 2025 Maserati GT2 Stradale, 2024 Maserati Ghibli, 2023 Maserati Ghibli, 2022 Maserati Ghibli, 2021 Maserati Ghibli, 2020 Maserati Ghibli and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
