Is the Honda e:HEV / i-MMD reliable?

The Honda e:HEV hybrid system (formerly i-MMD) has no serious, widespread faults documented in the sources consulted. The most cited issue is the 12 V battery going flat when the car stands unused and, on the 2.0, a recall for the high-pressure fuel pump.^[1][2][3]

See the 3 of the Honda e:HEV / i-MMD faults

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.^[4][5][6][7]
