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 1.2 16v reliable?

The 1.2 16v (D4F) and its 8-valve predecessor, the D7F, are simple naturally aspirated engines, used for over two decades as the entry-level option in Renault and Dacia cars, with a reputation for reliability: the reliability pages consulted document no catastrophic failures and no oil consumption. The most-cited problems are ignition coils and sensors and, on higher-mileage cars, the head gasket.^[6][7][8][9]
