1.5 dCi vs 2.0 and 2.2 CRDi: which engine is more reliable?

According to our risk index, the 2.0 and 2.2 CRDi carries less risk than the 1.5 dCi: 38/100 (moderate risk) versus 63/100 (high risk). The 1.5 dCi has 4 documented serious faults, the main one being «Wear and seizure of the big-end bearings»; the 2.0 and 2.2 CRDi has 2 documented serious faults, the main one being «High oil consumption from worn piston rings and valve guides (2.2 CRDi)».

Is the 1.5 dCi reliable?

The post-2010 1.5 dCi engines, especially the 90 hp, have a good record. The Euro 3 and Euro 4 units (2001-2010) carry serious faults: big-end bearings that can wreck the engine, a Delphi pump that fills the injection system with metal filings and, in some 105/110 hp versions, a timing belt and dual-mass flywheel that fail early.[1][2][3][4]

Is the 2.0 and 2.2 CRDi reliable?

The R family groups the 2.0 CRDi (D4HA, 136-185 hp) of the compact SUVs (Tucson, ix35, Sportage) and the 2.2 CRDi (D4HB, 197-202 hp) of the large ones (Santa Fe, Sorento): Bosch common rail, variable-geometry turbo and chain-driven timing. The 2.2 CRDi can suffer high oil consumption from 100,000 km in the Santa Fe and a turbo that is expensive to repair between 100,000-150,000 km in the Sorento; for the 2.0 CRDi we have not found sources with a specific serious fault.[5][6][7]
