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 1.8 T 20v reliable?

With up-to-date maintenance, the 20-valve 1.8T has a reputation as a powerful, durable engine for its time, but owner reports document recurring faults: ignition coils (especially on 2001 to 2003 units), water pump and air mass meter, and less often the turbo -sometimes linked to growing oil consumption- and the timing chain tensioner.[4][5][6][7][8][9]
