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 1.2 Dualjet and 1.2 VVT reliable?

The Suzuki 1.2 VVT and 1.2 Dualjet (K12B/K12C/K12M) is a naturally aspirated petrol engine with a timing chain and indirect injection, fitted since 2008 to the Splash, Swift, Ignis and Baleno, with an SHVS mild-hybrid variant since 2016. It is reliable: there is no serious documented fault with the engine block itself; the main points are a clutch that wears out sooner than expected on some cars and two SHVS recalls that have already been resolved.[4][5][6][7][8]
