Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS004440 MTB 24-37 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 MAS004440 MTB 24-37 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 MAS004440 MTB 24-37 cover?
The manufacturer filed it against 4 model years: 2024 Maserati MC20, 2023 Maserati MC20, 2022 Maserati MC20, 2021 Maserati MC20. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
