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.^[1][2][3][4]

Is the Honda e:HEV / i-MMD reliable?

The Honda e:HEV hybrid system (formerly i-MMD) has no serious, widespread faults documented in the sources consulted. The most cited issue is the 12 V battery going flat when the car stands unused and, on the 2.0, a recall for the high-pressure fuel pump.^[5][6][7]
