Is the 0.9 TCe reliable?

The 0.9 TCe (H4Bt) is a three-cylinder turbo with a good reliability reputation, better than that of its sibling the 1.2 TCe: it does not share the same oil consumption or the same rate of chain problems. Its most-cited weak point is a coolant leak at the thermostat housing, which if ignored can end up damaging the head gasket; chain, turbo and lambda sensor cases appear less often.[1][2]

Is the 1.4 and 1.6 16v reliable?

The K4J (1.4) and K4M (1.6), both naturally aspirated 16-valve units, are simple and generally reliable petrol engines: no source consulted documents oil consumption or faults that destroy the block. Their most-cited weak point is the ignition coils, followed by the crankshaft sensor and, on versions with a variable valve timing unit, its pulley; a neglected belt can cause serious damage, as one case in the Renault Laguna II documents.[3][4][5][6]
