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.[1][2][3]

Is the 1.5 K15B (Jimny) reliable?

The 1.5 K15B in the Suzuki Jimny is a 102 hp naturally aspirated four-cylinder with a timing chain, simple and with no documented faults of its own. The only thing recorded in Europe is a 2018-2020 recall for the fuel pump, precautionary and with a definitive remedy.[4][5][6]
