Maserati filed this with NHTSA as a manufacturer communication dated Jul 1, 2026, received Jul 15, 2026, about the power train. It names 17 model years (2022–2026). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
