Is the 1.6 EcoBoost reliable?

It is a turbocharged direct-injection four-cylinder that Ford used between 2010 and 2018 as a mid-range step across much of its European line-up, and which Volvo sold under its own T3/T4 designations. Its most serious fault is overheating caused by a loss of coolant circulation that can crack the cylinder head and cause a fire: Ford has recalled cars in South Africa and in the US/Canada, although we have not confirmed an equivalent campaign in Spain.^[1][2][3]

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.^[4][5][6]
