Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 13 complaints with NHTSA since 2015. 6 of them name Service Brakes — 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 2023 Maserati Grecale. The contact stated that while driving 20 MPH and approaching a stop sign, the brake pedal was depressed, but the vehicle failed to stop as intended, made a loud revving sound, and the vehicle decelerated to approximately 15 MPH. There was no warning light illuminated.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati 733 a recall?
No. A service campaign 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 733 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 733 cover?
The manufacturer filed it against 3 model years: 2025 Maserati Grecale, 2024 Maserati Grecale, 2023 Maserati Grecale. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
