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 Skyactiv-D reliable?

The Skyactiv-D is a modern and generally reliable diesel, but across its three displacements (1.5, 1.8 and 2.2) it shares oil dilution with diesel fuel during diesel particulate filter regenerations, which means you need to watch the oil level and not stretch oil changes, especially on short journeys; the older 2.2s (2012-2014) also accumulate more turbo and carbon build-up cases.^{[7][8][9][10]}
