Is the BMW N20 reliable?

The BMW N20 (2011-2017) was the first turbocharged four-cylinder with which BMW replaced its naturally aspirated six-cylinders in models such as the 320i, 328i and X3, and it is generally mechanically sound. Its best-documented weak point is the timing chain guides and tensioner on units built before 2015; oil leaks, the electric water pump and, to a lesser extent, the turbo and the high-pressure fuel pump are also known issues.^[1][2]

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.^[3][4][5][6]
