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.

The manufacturer filed it against 4 model years: 2025 Maserati Grecale, 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.
