Is the BMW N52 / N53 reliable?

The BMW N52 (2004-2015, port injection) is considered very reliable for a BMW, with known weak points (electric water pump, oil seals, valve cover). The N53 (2007-2013, direct injection) adds piezoelectric injectors prone to failure, which make it more expensive to maintain.^[1][2][3]

Is the 1.3, 1.5 and 1.6 gasolina (serie M) reliable?

Suzuki's M series (the 1.3-litre M13A, 1.5-litre M15A and 1.6-litre M16A, with a timing chain and indirect injection) has a reputation as a simple, reliable engine: we have found no documented serious fault in the block or the chain. What is on record are minor faults or one-off campaigns: the catalytic converter and lambda sensors of the 2005-2010 Swift, the catalytic converter of the 2006-2007 SX4, the Swift's fuel hose and the Grand Vitara and Jimny tensioner pulley.^{[4][5][6][7][8][9]}
