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 TCe / SCe reliable?

The 1.0 TCe/SCe (H4D/H4Dt) is a simply designed three-cylinder with reasonable reliability. Its most-cited fault is a noise or vibration from the turbo wastegate; the ECO-G (LPG) version adds its own gas-management faults and a 2023 recall over a risk of leaks and fire from the tank. An isolated case of a failed high-pressure pump is also documented, and no oil consumption pattern.^[7][8][9]
