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]

Is the 2.0 16v F4R and F4RT reliable?

In the sources we consulted, the 2.0-litre F4R and F4RT show no engine-destroying design faults, but the timing belt must be changed on time, and the coils (RS) and the variable valve timing pulley appear as weak points. We have found no reliable sources on oil consumption or big-end bearings.[4][5][6][7]
