Is the 1.2 PureTech reliable?

The belt-driven 1.2 PureTech (2012-2025) has a problem acknowledged by Stellantis: the oil-bath timing belt can degrade, block lubrication and, on the 2013-2018 turbos, damage the brake servo vacuum pump. The 2014-2023 turbos can also use oil. Stellantis offers 10 years or 180,000 km of cover; the chain-driven generation (from 2023) no longer uses that belt.^{[1][2][3][4][5]}

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.^[6][7][8]
