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 2.3 VR5 (V5) reliable?

The 2.3-litre VR5 is a naturally aspirated five-cylinder with the timing chain at the rear of the engine. Gebrauchtwagenberater rates it as a buy with no known problems in the Golf IV, but in the Bora it warns that the chain sometimes stretches; AutoHints adds the coils and the plastic coolant parts as points to watch.[4][5][6][7]
