What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 10 complaints with NHTSA since 2015. 4 of them name Electrical System — 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.
BRAKE FAILURE - SAFETY DEFECT RELEASED BY DEALER Brake pad warning light first appeared in February 2026. Dealer advised replacing rear brake pads. I chose to have the service performed at German Auto Care using original Maserati brake pads. Warning light continued intermittently after replacement.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS004115 MTB 24-22 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 MAS004115 MTB 24-22 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 MAS004115 MTB 24-22 cover?
The manufacturer filed it against 3 model years: 2024 Maserati Grecale, 2023 Maserati Grecale, 2022 Maserati Grecale. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
