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 2.7 and 4.0 gasolina (2TR-FE and 1GR-FE) reliable?

The sources consulted describe them as robust chain-driven engines with few documented faults: on the 4.0 V6 (1GR-FE), the water pump, head gasket on early units and the coils; on the 2.7 (2TR-FE), the front crankshaft seal in the early years. Almost all the data comes from technical websites, not official campaigns.[4][5][6][7]
