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 1.3, 1.5 and 1.6 gasolina (serie M) reliable?

Suzuki's M series (the 1.3-litre M13A, 1.5-litre M15A and 1.6-litre M16A, with a timing chain and indirect injection) has a reputation as a simple, reliable engine: we have found no documented serious fault in the block or the chain. What is on record are minor faults or one-off campaigns: the catalytic converter and lambda sensors of the 2005-2010 Swift, the catalytic converter of the 2006-2007 SX4, the Swift's fuel hose and the Grand Vitara and Jimny tensioner pulley.^{[4][5][6][7][8][9]}
