Skyactiv-D vs 2.0/2.2 D-4D: which engine is more reliable?

According to our risk index, the Skyactiv-D carries less risk than the 2.0/2.2 D-4D: 55/100 (high risk) versus 77/100 (very high risk). The Skyactiv-D has 3 documented serious faults, the main one being «Oil dilution with diesel during DPF regenerations»; the 2.0/2.2 D-4D has 1 documented serious fault, the main one being «Warped cylinder head gasket and oil consumption on the 2.2 D-4D».

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.^[1][2][3][4]

Is the 2.0/2.2 D-4D reliable?

No: the 2.0/2.2 D-4D family is among the most problematic Toyota diesels. The 2.2 block (2AD-FTV and 2AD-FHV D-CAT) has a large number of cases of warped cylinder head gaskets and oil consumption or dilution in the Avensis, RAV4, Auris, Corolla Verso and Verso; the EGR valve and injectors fail frequently across the whole family, and the D-CAT filter clogs up if the car is not driven regularly on open roads.^[5][6][7][8]
