Is the 1.9 dCi reliable?

The 1.9 dCi (F9Q) was Renault's first common-rail diesel (1999) and powered a large part of its range, and those of Nissan and Volvo, for more than a decade. It has well-documented weak points: on versions of up to 120 hp built before 2005, the big-end bearings can seize and the turbo tends to degrade around 150,000 km; the injectors, the EGR valve and, on the 120 hp versions, the dual-mass flywheel also fail fairly often.^{[1][2][3][4][5]}

Is the VM Motori 2.8 and 3.0 CRD reliable?

The VM Motori 2.8 CRD (four-cylinder) and 3.0 CRD V6 diesels from Jeep, Chrysler and Lancia show no systemic fault in open sources: they describe injector wear, a dirty EGR and a high-mileage turbo, and AUTO BILD says durability complaints about the 3.0 are very rare. The UK DVSA identifies only one engine campaign for the 3.0 (2025).^[6][7][8][9]
