Is the 1.3 TCe reliable?

The 1.3 TCe / 1.3 DIG-T (H5Ht at Renault and Dacia, HR13DDT at Nissan, M282 at Mercedes-Benz), developed with Daimler since 2018, has a clearly better record than its predecessor, the 1.2 TCe: no oil consumption or chain problems have been documented. It had manufacturing defects that have since been corrected (injectors, calibration, turbo, timing) and, on the Captur II and Clio V, a fuel pump fuse failure with no confirmed official fix.^[1][2][3]

Is the 1.6 and 1.8 Ecotec 16v reliable?

The 1.6 and 1.8 16v Ecotec (Z16XER/A16XER, Z18XER/A18XER) that Opel fitted between 2005 and 2015 to the Astra H and J, Zafira B, Vectra C and Insignia A have a reputation as reliable naturally aspirated engines: the sources consulted document no serious faults or failure patterns, only minor problems such as ignition coils and, on the 1.8, leaks from the oil cooler or thermostat.^[4][5][6][7]
