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 2.7 and 4.0 gasolina (2TR-FE and 1GR-FE) reliable?

The sources consulted describe them as robust chain-driven engines with few documented faults: on the 4.0 V6 (1GR-FE), the water pump, head gasket on early units and the coils; on the 2.7 (2TR-FE), the front crankshaft seal in the early years. Almost all the data comes from technical websites, not official campaigns.[6][7][8][9]
