1.6 EcoBoost vs 1.0 MPI: which engine is more reliable?

According to our risk index, the 1.0 MPI carries less risk than the 1.6 EcoBoost: 19/100 (low risk) versus 59/100 (high risk). The 1.6 EcoBoost has 3 documented serious faults, the main one being «Cracked cylinder head from overheating, with fire risk»; the 1.0 MPI has no documented serious faults.

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 MPI reliable?

The 1.0 MPI is a simple, low-powered (60-75 hp) naturally aspirated three-cylinder engine with no serious or systemic faults documented. Its most frequently cited issues are above-normal oil consumption -- especially in the Seat Ibiza V -- and, more occasionally, a cooling system fault with the engine light and vibrations. The timing belt has no fixed replacement interval and shows no failure pattern.^[4][5][6][7]
