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 BlueHDi reliable?

The 2.0 BlueHDi is mechanically one of the sturdiest PSA/Stellantis diesels: in the samples available for its 150 to 180 hp versions, the turbo, DPF, EGR and injectors fail noticeably less often than on earlier generations of the same engine from before 2013. Its documented weak point is the AdBlue tank, a fault so widespread that Stellantis compensates affected owners without a definitive fix.^[5][6][7][8]
