Is the MZR-CD reliable?

The MZR-CD is Mazda's most widespread diesel between 2002 and 2013, fitted to the Mazda3, Mazda6, Mazda5 and CX-7. It is sensitive to short journeys: the injector seals and incomplete DPF regenerations can dilute the oil, and the EGR and intake build up carbon. The 2.2-litre redesign (from 2008), with a timing chain instead of a belt, adds the risk of that chain stretching and damaging the engine.^[1][2][3][4]

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).^[5][6][7][8]
