2018 Nissan Micra 1.0L Petrol · MW68 WKE

Sharing its CMF-B platform architecture with the Renault Clio, the K14 Micra commonly suffers from premature wear to its front lower suspension wishbone rear voided bushes and strut top mount bearings. Repeated impacts from UK speed humps and potholed roads cause the rubber to perish and split, resulting in noticeable knocking sounds, vagueness around the straight-ahead steering position, and rapid uneven inner shoulder tyre wear.

The Renault-sourced 1.5 dCi (K9K) turbodiesel fitted to early K14 Micras requires prolonged exhaust temperatures to initiate active DPF regeneration. Because the Micra is predominantly used as a short-journey urban runabout in the UK, uncompleted regeneration cycles cause excessive soot build-up, DPF warning lamps, and diesel fuel washing down cylinder walls into the engine sump, diluting the lubricating oil.

Under DVSA safety recall R/2023/095 affecting K14 Micras manufactured between 2017 and late 2021, the seat slide rail mechanism could suffer from stress limit issues when adjusted to specific track positions. Under severe deceleration or impact, inadequate locking engagement could allow the seat to shift or detach from the rail runner. Dealerships inspect the seat rails and install reinforced locking pins or replacement track assemblies.
