Is the 1.8 TCe reliable?

The 1.8 TCe (M5P) in the Alpine A110 and the Mégane R.S. IV has no documented endemic faults. What has been published are recalls for the A110: the oil pressure solenoid valve (2019) and the fuel pump (2021 and 2023). We have found no recalls or complaints about this engine in the Mégane R.S.[1][2][3][4]

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.[5][6][7]
