What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCertain 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.

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 RAPID UPDATE 754 cover?
