1.0 PureTech vs 2.0 EcoBoost: which engine is more reliable?

According to our risk index, the 2.0 EcoBoost carries less risk than the 1.0 PureTech: 38/100 (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 2.0 EcoBoost has 1 documented serious fault, the main one being «Coolant entering the cylinders through block cracks».

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 2.0 EcoBoost reliable?

This is the direct-injection turbo 2.0 that Ford fitted from 2010 to the Mondeo, S-Max, Galaxy, Kuga and Focus ST, and that Volvo, Land Rover and Jaguar also used. Its most serious weak point is cracks in the block that let coolant into the cylinders (a Ford bulletin in North America; cited for the Mondeo and Kuga); we have not found a European recall.^[5][6][7][8]
