Reliability, common problems and owner reviews for the Renault Kadjar 1.3 TCe (mild-hybrid). Check this before you buy used.
The 1.3 TCe (H5Ht with 12V mild-hybrid — the Renault-Mercedes co-developed unit, the same physical engine as the Mercedes 1.3 M282 and shared across the Mégane/Kadjar/Captur and Nissan Qashqai) is the conventional Arkana engine: willing, reasonably economical and a clear improvement over Renault's troubled earlier 1.2 TCe. It's chain-driven direct-injection turbocharged, so the cautions are intake-valve carbon over time, turbo/PCV care, and the EDC dual-clutch wanting fluid discipline. A serviced car on clean oil with a healthy EDC is dependable. Buy on oil and gearbox history; the E-Tech hybrid is the alternative for town economy.
