Service campaign MAS004396_A RU 24-38
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Certain Maserati GranTurismo (M189) and GranCabrio (M190) MY24 listed in MODISCS+ are involved in a Rapid Update to update the ECM (Engine Control Module) software. This action is necessary to enhance the operational strategy of the air shutter grid (AGS). In certain conditions, the engine coolant temperature may rise, prompting the ECM to limit engine performance to prevent overheating and potential component damage.
