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 1.5 / 2.0 EcoBlue reliable?

EcoBlue has been Ford's diesel family since 2016, with two very different engines despite the shared name: the 2.0 (codenamed «Panther») debuted a wet timing belt (belt-in-oil) and a second wet belt for the oil pump, the same type of design that has caused problems on other Ford engines; the 1.5, by contrast, uses a conventional dry belt. The 2.0 powers vans, SUVs and large saloons; the 1.5 the smaller models.[5][6]
