Reliability, common problems and owner reviews for the Suzuki Baleno 1.2 Dualjet (K12C). Check this before you buy used.
The 1.2 Dualjet (K12C, naturally-aspirated four with twin injectors — shared with the Swift and Ignis) is the simple, dependable, ultra-frugal Baleno engine and exactly what makes Suzuki's small cars so trusted: no turbo, chain-driven, light and economical, with a strong reliability record. It's modest on power but the Baleno is so light it doesn't matter much around town. Cautions are trivial age items — coils, sensors, the odd oil/coolant niggle. The honest, low-worry choice, often paired with the SHVS mild-hybrid starter-generator (keep that healthy).
