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 Porsche V8 and V6 (Cayenne and Panamera) reliable?

There are no public failure statistics for these engines. The sources agree on three points: the plastic coolant pipes of the first Cayenne V8s, cylinder bore scoring in the naturally aspirated 4.5, and the timing chain of the VR6 V6s. On the 4.8 and the Panamera, the camshaft adjuster bolts (a 2012 workshop campaign) and leaks weigh more.[6][7][8][9][10][11][12][13]
