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 1.0 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]
