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 1.0 SCe (B4D) reliable?

The 1.0 SCe (B4D) is a simple, low-power (70-75 hp) naturally aspirated three-cylinder engine, with no serious or systemic faults documented. Its most cited issues are a clutch that can slip or judder when cold and, more occasionally on the Dacia Sandero II, higher-than-normal oil consumption; there is no pattern of faults in the chain-driven timing.[4][5][6]
