Is the 1.5 BlueHDi reliable?

The 1.5 BlueHDi has a serious weak point in engines built from October 2017 to January 2023: the 7 mm chain linking the camshafts can stretch and break. Stellantis has recalled them and covers this fault for 10 years or 240,000 km; engines built up to August 2020 can also suffer AdBlue tank failures, with partial compensation from the manufacturer.[1][2][3][4]

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.[5][6][7][8]
