Is the 1.0 PureTech reliable?

It is a simple naturally aspirated three-cylinder, but with two documented weak points: oil consumption through the piston rings, which Stellantis acknowledges across its entire production (2012-2016), and the oil-bath timing belt it shares with the 1.2. It is only recommended with a full service history, a consumption test and a checked belt.[1][2][3][4]

Is the 1.25/1.4/1.6 Ti-VCT reliable?

The Ti-VCT is Ford's family of naturally aspirated petrol engines (Sigma, Zetec-SE or Duratec), in 1.25, 1.4, 1.5 and 1.6 litres, fitted to the Fiesta, Focus, C-Max, B-Max, EcoSport and Ka+ between 2003 and 2022. It is a reliable engine in general: its best-documented fault, a variable valve timing actuator that could seize, is concentrated in the oldest units (Focus II and C-Max I) and was corrected afterwards.[5][6][7][8]
