Maserati bulletin MAS005186 MCL 26-16
Maserati filed this with NHTSA as a manufacturer communication dated Jul 20, 2026, received Aug 3, 2026, about the unknown or other. It names 7 model years (2021–2026). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWe are informing you that tool p/n 900100024 has been updated with an additional component designed to improve the oil seal installation process on V6 Nettuno engines. This added component helps ensure consistent, accurate positioning of the oil seal in its seat by compensating for dimensional gaps and seal tolerances. It also improves process reliability by helping maintain proper installation conditions, even when tool usage is not optimal.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS005186 MCL 26-16 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 MAS005186 MCL 26-16 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 MAS005186 MCL 26-16 cover?
The manufacturer filed it against 7 model years: 2025 Maserati MC20, 2024 Maserati MC20, 2023 Maserati MC20, 2022 Maserati MC20, 2021 Maserati MC20, 2026 Maserati MC20 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
