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 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]
