Reliability, common problems and owner reviews for the Hyundai Kona 1.0 / 1.6 T-GDI (turbo petrol). Check this before you buy used.
The T-GDI turbo petrols — the 1.0 three-cylinder and the punchy 1.6 — give the Kona lively, economical performance. They're modern turbo direct-injection engines, so the cautions are turbo and PCV care, clean correct-spec oil, and direct-injection intake carbon over time; the 1.6 T-GDI is paired with a 7-speed dual-clutch (check it). Generally well-regarded and trouble-free when serviced; keep oil fresh and check the DCT and boost. A good, willing modern engine.
