Is the 2.2 Ecotec gasolina reliable?

This is the 2.2 petrol engine producing 147 to 155 hp in the Astra G, Zafira, Vectra and Signum. Its documented weak point is the timing chain, which stretches and can end in serious engine damage; the 2.2 Direct adds a high-pressure pump prone to failure.[1][2][3]

Is the 1.2 16v reliable?

The 1.2 16v (D4F) and its 8-valve predecessor, the D7F, are simple naturally aspirated engines, used for over two decades as the entry-level option in Renault and Dacia cars, with a reputation for reliability: the reliability pages consulted document no catastrophic failures and no oil consumption. The most-cited problems are ignition coils and sensors and, on higher-mileage cars, the head gasket.[4][5][6][7]
