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 faults

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]
