Is the 1.5 VC-Turbo e-Power reliable?

There is still little reliability data: the three-cylinder 1.5 VC-Turbo only generates electricity and no mechanical faults are known in Europe. The documented weak points are in the e-Power electronics: battery campaigns and isolated cases of immobilisation.[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]
