Is the 1.2 8v Fire reliable?

The 1.2 8v Fire is one of Fiat's simplest and most widespread petrol engines, with more than two decades in production and no serious or systemic faults documented. The sources consulted describe it as robust: its most-cited issues are isolated sensor failures (lambda sensor, crankshaft sensor), the ignition coil and somewhat high oil consumption at higher mileages; there is no pattern of timing belt breakage.[1][2][3][4][5][6]

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.[7][8][9]
