Is the 1.6 CRDi reliable?

The U2 D4FB (2009-2018) is a generally robust diesel if well maintained, with known turbo failures in the early units and timing chain problems from 120,000-150,000 km. Its successor, the Smartstream (U3 D4FE, from 2018), has a good reputation, except in the 48V mild hybrid version, which has a belt tensioner and crankshaft pulley fault that can destroy the engine.[1][2][3]

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).[4][5][6][7]
