The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.4 / 1.6 16v E-TEC II reliable?
The 1.4 and 1.6 16v GM Daewoo E-TEC II (first-generation Lacetti/Optra and Aveo) have a timing belt and, according to the Polish press, a moderate fault record. Documented issues are faulty valves in the first units (2004-2005), lambda sensor faults and a few cases of oil leaks or oil consumption.[1][2][3]
See the 3 of the 1.4 / 1.6 16v E-TEC II faultsIs the Skyactiv-G reliable?
The Skyactiv-G is a naturally aspirated petrol engine that the German specialist press consistently describes as reliable, with no documented pattern of serious engine faults in any Mazda model reviewed. Its weak point, shared with almost any direct-injection petrol engine, is carbon build-up in the intake; in addition, 2017-2020 units had recalls for software and for the fuel pump, since fixed by the manufacturer.[4][5][6][7]
