Is the 1.2 TCe reliable?

Only with reservations: 1.2 TCe and 1.2 DIG-T engines built between 2012 and mid-2016 can burn a lot of oil because of poor piston ring sealing, with a risk of damaging the valves, stretching the chain or destroying the engine. Renault and Nissan dealt with it through technical notes and case-by-case assistance, without a recall; later production incorporates the fix.^{[1][2][3][4][5]}

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.^[5][6]
