Is the Isuzu 2.5 / 3.0 / 1.9 Ddi reliable?

These are the diesels of the Isuzu D-Max: the 2.5 twin-turbo (4JK1) and the 1.9 Ddi (RZ4E) of the European range, and the 2.5 and 3.0 of the Latin American Chevrolet D-Max. Auto Express speaks of enviable reliability; what is documented is diesel in the oil of the 2.5 on short journeys, soot in the EGR and a 2017 campaign for the camshaft gear.^[1][2][3][4]

Is the 2.2 MultiJet / BlueHDi (Stellantis) reliable?

The 2.2 diesels of Stellantis's large vans (BlueHDi DW12 in the Boxer, Jumper and Movano; Multijet 3 in the Ducato) are recent engines with no fault statistics of their own. What is documented are campaigns: AdBlue and SCR software, and the fuel return pipe on 2024-2025 units, with a fire risk. Long-term history is missing.^{[5][6][7][8][9]}
