Maserati service campaign RAPID UPDATE 770
Maserati filed this with NHTSA as a service campaign dated Mar 29, 2025, received Dec 19, 2024, about the unknown or other — 2 documents under this number: MAS004653 RU 25-05, MAS004444 RU 24-43. It names 2 model years (2025). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
