2018 Ford KA 1.2L Petrol · E26 HJS

On urban-driven Ka+ models with the 1.2-litre petrol engines, stop-start city commuting and prolonged clutch slipping cause friction lining overheating and uneven glazing across the clutch driven plate. As the friction surface hardens, the clutch develops severe low-frequency vibration and judder when taking off in first gear or reversing from cold, which eventually wears down the pressure plate diaphragm fingers.

On Ka+ models manufactured between September 2017 and May 2019, an incorrectly routed and unfused wiring harness lead for the Battery Monitoring System (BMS) can become pinched beneath or rub against the metal battery tray and retaining bracket. Continuous vehicle vibration wears through the wire insulation, creating an unfused dead short to earth against the chassis. This triggers a serious safety hazard resulting in smoke, harness melting, and potential under-bonnet fire. Ford issued safety recall 19S21 (DVSA recall R/2019/189) where technicians inspect routing, wrap the harness in protective abrasion-resistant tape, and secure it with a revised retention clip.

Built on Ford global B2E platform with MacPherson front struts, the Ka+ commonly suffers from premature deterioration of its front suspension lower wishbone rear voided bushes and anti-roll bar drop links when driven over rough UK road surfaces and traffic-calming cushions. Motoring reviews and owner surveys highlight that pothole-strewn urban streets place severe stress on the running gear and alloy wheels. As rubber bushes split and drop link ball joints develop play, the vehicle generates prominent knocking noises over road irregularities, exhibits vague steering wandering under braking, and fails MOT inspections due to excessive front axle suspension play.
