Is the 1.5 VC-Turbo e-Power reliable?

There is still little reliability data: the three-cylinder 1.5 VC-Turbo only generates electricity and no mechanical faults are known in Europe. The documented weak points are in the e-Power electronics: battery campaigns and isolated cases of immobilisation.^[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]}
