1.0 TCe / SCe vs E-Tech Híbrido: which engine is more reliable?

According to our risk index, the E-Tech Híbrido carries less risk than the 1.0 TCe / SCe: 32/100 versus 41/100 (both moderate risk). The 1.0 TCe / SCe has 1 documented serious fault, the main one being «LPG (ECO-G) system faults and tank recall»; the E-Tech Híbrido has 2 documented serious faults, the main one being «Multi-mode gearbox failure (risk of breakage)».

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.[1][2][3]

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.[4][5][6]
