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 1.6 and 1.8 Ecotec 16v reliable?

The 1.6 and 1.8 16v Ecotec (Z16XER/A16XER, Z18XER/A18XER) that Opel fitted between 2005 and 2015 to the Astra H and J, Zafira B, Vectra C and Insignia A have a reputation as reliable naturally aspirated engines: the sources consulted document no serious faults or failure patterns, only minor problems such as ignition coils and, on the 1.8, leaks from the oil cooler or thermostat.[4][5][6][7]
