1.6 CRDi 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 1.6 CRDi: 38/100 (moderate risk) versus 70/100 (high risk). The 1.6 CRDi has 4 documented serious faults, the main one being «MHSG belt tensioner and crankshaft pulley failure (48V mild hybrid)»; 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 1.6 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 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.^[4][5][6]
