Is the 2.2 JTDm Multijet II reliable?

Alfa Romeo's 2.2 diesel (Giulia and Stelvio) has a good reputation: a German guide rates it as very reliable and a 210 hp Stelvio covered 100,000 km in a test without any faults. The sources mainly record leaks and oil consumption, the odd particulate filter and EGR case, and two one-off campaigns: the fuel filter gasket (2018 Giulia) and the alternator cable next to the EGR pipe (2017-2018 Stelvio).^{[1][2][3][4][5][6]}

Is the e-Skyactiv D 3.3 reliable?

The e-Skyactiv D 3.3 is an inline-six diesel with mild-hybrid assistance that Mazda debuted in the CX-60. It is a very recent engine: there is no in-service reliability data, and what is documented are software recalls (stalling, restarting, clutch) fixed at the official dealer.^[7][8][9]
