1.6 / 2.2 i-DTEC vs 2.4 / 2.8 D-4D (GD): which engine is more reliable?

According to our risk index, the 2.4 / 2.8 D-4D (GD) carries less risk than the 1.6 / 2.2 i-DTEC: 20/100 (low risk) versus 54/100 (high risk). The 1.6 / 2.2 i-DTEC has 3 documented serious faults, the main one being «Turbocharger failure»; the 2.4 / 2.8 D-4D (GD) has no documented serious faults.

Is the 1.6 / 2.2 i-DTEC reliable?

The i-DTEC is Honda's diesel family from 2008, with two four-cylinder blocks: the 2.2 (Accord, CR-V) and, from 2013, the 1.6 (Civic, CR-V, HR-V). It uses a timing chain instead of a belt and common-rail injection. The basic architecture has a good reputation for longevity, but the emissions system (DPF and EGR) and the turbocharger account for most of the faults documented by owners themselves.[1][2][3][4]

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.[5][6][7]
