1.0 PureTech vs 1.8 and 2.0 XU: which engine is more reliable?

According to our risk index, the 1.8 and 2.0 XU carries less risk than the 1.0 PureTech: 39/100 (moderate risk) versus 59/100 (high risk). The 1.0 PureTech has 2 documented serious faults, the main one being «Excessive oil consumption through the piston rings»; the 1.8 and 2.0 XU has 1 documented serious fault, the main one being «Premature timing belt breakage in the 16-valve engines».

Is the 1.0 PureTech reliable?

It is a simple naturally aspirated three-cylinder, but with two documented weak points: oil consumption through the piston rings, which Stellantis acknowledges across its entire production (2012-2016), and the oil-bath timing belt it shares with the 1.2. It is only recommended with a full service history, a consumption test and a checked belt.^[1][2][3][4]

Is the 1.8 and 2.0 XU reliable?

These are naturally aspirated 1.8 and 2.0-litre petrol engines with no serious documented design faults outside the 16-valve timing belt: the 1.8 16v built until late 1997 had a recall for premature breakages, and the 2.0 16v in the GTi-6 calls for shorter belt change intervals. The rest are minor faults: coolant and oil leaks, sensors and idle.^[5][6][7][8]
