Is the Honda IMA híbrido reliable?

Honda's IMA hybrid system (Insight II, Jazz Hybrid, CR-Z and Civic Hybrid) has a good reputation for reliability in the British press, and its documented weak point is the ageing of the high-voltage battery, which turns on the IMA warning light. There were also two one-off campaigns: the DC/DC converter on the 2006 Civic Hybrid and the CR-Z software.[1][2][3]

Is the 0.9 TCe reliable?

The 0.9 TCe (H4Bt) is a three-cylinder turbo with a good reliability reputation, better than that of its sibling the 1.2 TCe: it does not share the same oil consumption or the same rate of chain problems. Its most-cited weak point is a coolant leak at the thermostat housing, which if ignored can end up damaging the head gasket; chain, turbo and lambda sensor cases appear less often.[4][5]
