Maserati bulletin MAS004816_A MTB 26-04
Maserati filed this with NHTSA as a manufacturer communication dated Apr 15, 2026, received Apr 17, 2026, about the fuel/propulsion system. It names 39 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 MAS004816_A MTB 26-04 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.

Is the MAS004816_A MTB 26-04 repair free?
