Is the 1.5 VTi-TECH / T-GDI reliable?

MG/SAIC's "1.5" covers two different engines: the naturally aspirated VTi-TECH (106 hp), the entry-level engine in the MG ZS, and the turbocharged T-GDI (162-170 hp), found only in the MG HS and as the petrol engine in its plug-in hybrids. Neither has well-documented engine faults in independent sources yet: the complaints published concern electronics, the automatic gearbox and finish, not the engine block.[1][2][3][4][5][6]

Is the 1.0, 1.4 and 1.6 8v EA111 reliable?

Eight-valve petrol engines, simple, with a timing belt. For the European 1.0 and 1.4, sources only record isolated incidents, mainly ignition faults in damp weather on the 1.4. In Brazil, the 2008-2010 1.0 VHT of the Gol, Voyage and Fox suffered lubrication-related noise, an oil campaign with extended warranty and a software recall in 2009.[7][8][9][10]
