Reliability, common problems and owner reviews for the Kia Sportage V 1.6 CRDi (D4FE, mild-hybrid). Check this before you buy used.
The 1.6 CRDi (D4FE, with 48V mild-hybrid — the well-proven U-line diesel shared across the i30/Kona/Ceed/Tucson) is the high-mileage Sportage V choice: refined, genuinely economical and dependable. Standard modern-diesel cautions: DPF clogging on short trips, EGR sooting, injector and turbo attention at high mileage, AdBlue/SCR, and the 48V starter-generator to keep healthy. It's a sound engine that mostly suffers only from short urban-only use that never lets the DPF regen. For a motorway commuter it's a low-thirst long-hauler — buy on oil, DPF and AdBlue history.
