Is the E-Tech Híbrido reliable?

The E-Tech combines a combustion engine (1.6 H4M naturally aspirated or 1.2 HR12 turbo) with electric motors and a multi-mode gearbox with no clutch or torque converter. Its best-documented weak point is the gearbox itself: reports from the Clio, Captur, Arkana, Austral, Duster and Jogger describe warnings of a risk of breakage, and Renault has launched two campaigns since 2020 (an electrical fault and a primary shaft seal). The 12 V battery also fails fairly often.^[1][2][3]

Is the 1.2 12V reliable?

The 1.2 12V is a simple, low-power, naturally aspirated three-cylinder engine (54-70 hp), with two documented design faults: the timing chain tensioner, which can end up destroying the engine, and -on the Volkswagen Polo IV- a catalytic converter too close to the cylinder head that can burn the exhaust valves. Ignition coil failures are also common, and there are isolated cases of oil consumption and vibration.^{[4][5][6][7][8]}
