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 2.0 dCi reliable?

The 2.0 dCi (M9R) is a Renault-Nissan Alliance diesel with known, well-documented weak points: the turbo and the EGR valve fail relatively often, the particulate filter clogs up in urban use, and there are cases of injectors and even the timing chain failing earlier than expected in several of the models that use it.^[5][6][7][8]
