About the Ford Fiesta Mk8
AI-generatedThe Ford Fiesta Mk8, launched in 2017, represented a significant evolution of Britain's best-selling car. Built on an updated version of the previous platform, this generation featured sharper styling with a more aggressive front end, a completely redesigned interior with an 8-inch touchscreen infotainment system (SYNC 3), and improved dynamics. Ford introduced a more sophisticated suspension setup and enhanced the award-winning 1.0-litre EcoBoost engine range, which remained the core of the lineup alongside naturally aspirated 1.1-litre petrol engines. This generation saw the introduction of advanced driver assistance features previously unavailable on the Fiesta, including adaptive cruise control, pre-collision assist with pedestrian detection, and active park assist. The ST performance variant continued with a more powerful 1.5-litre EcoBoost engine producing 200PS, whilst a mild-hybrid version (mHEV) joined the range in 2020. Production ceased in 2023 as Ford announced the discontinuation of the Fiesta after 47 years, making the Mk8 the final generation of this iconic supermini.

Owner Tips
- 1Check wet belt condition every 10,000 miles on 1.0 EcoBoost engines - consider preventative replacement at 100,000 miles or 10 years
- 2Test drive carefully for clutch judder; if present, negotiate significant discount as replacement can cost £1,000+
- 3Ensure all recalls have been completed, particularly the door latch recall from 2019
- 4Keep SYNC 3 software updated via Ford dealer or USB update to minimise freezing issues
- 5Check for coolant loss between services on 1.0 EcoBoost models - monitor levels regularly
- 6Consider extended warranty on 2017-2019 models due to known reliability issues
- 7Use Ford-approved oil (5W-20) for 1.0 EcoBoost engines and maintain strict service intervals
- 8Avoid short journeys if considering a diesel model to prevent DPF issues
