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]

Is the 2.0 and 3.0 Ingenium gasolina reliable?

The petrol Ingeniums (2.0 with 200 to 300 hp and the 3.0 six-cylinder with mild hybridisation) have a considerably better reputation than the diesel, but very little data has been published. We have only been able to document chain noise on some 2.0 engines, with no serious faults or campaigns.[4][5][6]
