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.[1][2][3]

Is the 2.4 / 2.8 D-4D (GD) reliable?

No serious mechanical faults are documented in the European sources we were able to open: AutoBild saw the 2.8 as more robust than the 3.0 it replaced, although it points to glow plugs that fail early. Its best-documented weak point is the particulate filter, with a lawsuit in Australia but no equivalent recall or legal action in Europe, and there are barely any high-mileage examples from which to judge long-term reliability.[1][4][5]
