Recalls 1 and 3 describe the same underlying airbag ECU defect. Recalls 4 and 5 describe the same door latch defect. I'll treat each pair as a single issue.
The 2016 Maserati GranTurismo has 3 recalls, the most serious being a faulty airbag control unit that can either leave the airbags inactive in a crash or fire them and the seatbelt pretensioners without any collision.
The fuel system recall affects vehicles built in the fall of 2015: the main fuel delivery line can corrode over time and develop a leak, and any nearby ignition source — a hot exhaust component or a spark — can turn that leak into a fire. The passenger-side door latch is also a concern on certain vehicles built in mid-2015. The latch components may not have been properly hardened during manufacturing, leaving them weaker than they should be. In a crash, a weakened latch can give way and allow the door to swing open, increasing the chance of occupants being ejected or struck by other vehicles.
