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 1.0 TCe / SCe reliable?

The 1.0 TCe/SCe (H4D/H4Dt) is a simply designed three-cylinder with reasonable reliability. Its most-cited fault is a noise or vibration from the turbo wastegate; the ECO-G (LPG) version adds its own gas-management faults and a 2023 recall over a risk of leaks and fire from the tank. An isolated case of a failed high-pressure pump is also documented, and no oil consumption pattern.[6][7][8]
