Reliability, common problems and owner reviews for the Renault Scénic III 1.6 16V (K4M). Check this before you buy used.
The 1.6 K4M is the simple, proven Renault petrol — dependable and cheap to run, but genuinely underpowered in a heavy MPV (slow when loaded with people). Belt-driven, so cam-belt discipline is essential (interference engine), with the usual coil and coolant-sensor niggles. Fine for gentle, light use; gutless fully loaded — most buyers are better served by a diesel here.
