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 2.0 and 2.2 16v EW10/EW12 reliable?

The EW10 (2.0) and EW12 (2.2) are naturally aspirated 16-valve petrol engines with a timing belt, which PSA fitted between 1999 and 2010 to the 206, 307, 406, 407, 607, 807, C4, C5 and C8, among others. According to owners there are no frequent internal failures: the most-cited problems are the ignition coils (the only fault also reported by the press), the exhaust and, on the 2.2, oil consumption.^{[4][5][6][7][8][9][10][11]}
