Is the 2.0 / 2.4 i-VTEC reliable?

Naturally aspirated Honda petrol engines (K20/K24 and R20) with a timing chain. The only serious documented fault is camshaft wear in the early K20s (2003-2004); the R20A and K24Z show no serious faults in the sources consulted, and only isolated cases of oil consumption appear. The sample of testimonies is small.^{[1][2][3][4][5][6]}

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.^{[7][8][9][10][11][12]}
