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 1.8 and 2.0 XU reliable?

These are naturally aspirated 1.8 and 2.0-litre petrol engines with no serious documented design faults outside the 16-valve timing belt: the 1.8 16v built until late 1997 had a recall for premature breakages, and the 2.0 16v in the GTi-6 calls for shorter belt change intervals. The rest are minor faults: coolant and oil leaks, sensors and idle.^{[7][8][9][10]}
