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 1.0, 1.4 and 1.6 8v EA111 reliable?

Eight-valve petrol engines, simple, with a timing belt. For the European 1.0 and 1.4, sources only record isolated incidents, mainly ignition faults in damp weather on the 1.4. In Brazil, the 2008-2010 1.0 VHT of the Gol, Voyage and Fox suffered lubrication-related noise, an oil campaign with extended warranty and a software recall in 2009.^[3][4][5][6]
