Maserati filed this with NHTSA as a service bulletin dated Oct 3, 2024, received Oct 15, 2024, about the suspension. It names 18 model years (2016–2024). 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.

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 databaseOwners of the 18 model years this bulletin names have filed 44 complaints with NHTSA since 2015. 2 of them name Suspension — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns a 2019 Maserati Ghibli. The contact stated while driving approximately 40 MPH, the vehicle drove over a dip in the roadway and the rear end swayed from left to right. The contact stated that at higher speeds the swaying made the vehicle more unstable. The contact stated no warning light was illuminated.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS004299 MCL 24-43 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 MAS004299 MCL 24-43 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 MAS004299 MCL 24-43 cover?
The manufacturer filed it against 18 model years: 2024 Maserati Ghibli, 2023 Maserati Ghibli, 2022 Maserati Ghibli, 2021 Maserati Ghibli, 2020 Maserati Ghibli, 2019 Maserati Ghibli and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
