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 Drive-E gasolina reliable?

The Volvo Drive-E petrol engine (2.0-litre 4-cylinder T2-T6/B4-B5 and, since 2018, 1.5-litre 3-cylinder T2-T3/B3) powers almost the entire Volvo range since 2013. Owners mainly document high oil consumption that can damage the turbo, carbon build-up on the intake valves caused by direct injection, and the odd coolant reservoir leak; we have not found Volvo acknowledging these faults with a campaign of its own for the petrol engine.[7][8][9]
