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 1.0 and 1.4 Boosterjet reliable?

The Suzuki Boosterjet (1.0 K10C and 1.4 K14C/K14D) is a turbocharged direct-injection petrol engine with a timing chain, fitted since 2015 to the Vitara, S-Cross, Swift Sport and Baleno, with a 48 V mild-hybrid variant of the 1.4 since 2020. German TÜV inspection reports and the workshops we consulted rate its reliability as high: no widespread fault with the chain, oil, fuel pump or mild-hybrid system is documented.[4][5][6][7][8]
