Overview
The Ford Fiesta Mk8 (2017-2023) was the last generation of Ford's iconic supermini before production ended in 2023. Offered as a 3-door and 5-door hatchback, along with the crossover-style Active, the sporty ST, and the hot ST200, it remained a benchmark for small car handling. Powered primarily by Ford's 1.0-litre EcoBoost turbocharged three-cylinder engine, it was one of the most efficient small cars of its generation. Production ended in June 2023 when Ford shifted strategy away from smaller vehicles.
Reliability
The Fiesta Mk8 has a reliability score of around 72/100. The 1.0 EcoBoost engine is generally reliable but requires strict coolant maintenance—a known weak point is cracked coolant pipes on earlier units. The 1.5 diesel is robust but less common. Automatic versions with the 6-speed DCT can experience hesitation at low speeds. Overall, with regular servicing the Fiesta is an dependable ownership proposition.
Running Costs
Fuel economy: 1.0 EcoBoost 100hp (45-55 mpg combined), 1.5 EcoBlue diesel (60-70 mpg). VED road tax: £20-£190/year depending on CO2 and registration date. Annual servicing: £150-£300 at Ford dealers; £100-£200 at independent garages. Insurance: £600-£1,800 annually depending on driver profile and trim level.
MOT Reliability
The Fiesta Mk8 has one of the better first-MOT pass rates in its class at around 76%. Most common MOT issues include tyre wear (the 1.0 EcoBoost can be hard on rear tyres), brake wear, and suspension bush wear after 60,000 miles. The ST performance variant has higher brake pad consumption. The 1.0 EcoBoost coolant system should be checked before MOT as leaks or overheating damage can create structural failures.
Common Problems
1. Coolant pipe cracking (1.0 EcoBoost): The plastic coolant pipe from the cylinder head can crack, causing coolant loss and overheating. Fix: coolant pipe replacement (£150-£350). 2. Dual-mass flywheel (manual gearbox): Can develop judder or rattling, particularly in early cars. Fix: flywheel replacement (£600-£1,200). 3. DCT hesitation (auto): The 6-speed dual-clutch automatic can hesitate or jerk when pulling away slowly. Often improved by software update. 4. Rear beam corrosion: Rear torsion beam can corrode, especially on earlier models. Check before buying.
Insurance
The Ford Fiesta Mk8 sits in insurance groups 8-20, making it one of the most affordable cars to insure. Entry-level 1.0 EcoBoost models (group 8-12) are ideal for young drivers. The Fiesta ST sits in group 20-28, reflecting its performance specification. Annual premiums range from £600-£1,800 depending on driver profile.
Road Tax (VED)
VED road tax for the Fiesta Mk8 varies from £20/year for the most efficient 1.0 EcoBoost variants (under 100g/km CO2, registered before April 2017) to the standard £190/year for vehicles registered after April 2017. The diesel 1.5 EcoBlue may have slightly lower first-year VED due to lower CO2.
Maintenance & Servicing
Service intervals: 10,000 miles or 12 months. Minor service: oil and filter change (£100-£180). Major service: full inspection + fluids (£250-£450). Timing: Belt-driven (not chain) on 1.0 EcoBoost—replacement typically needed at 10 years/100,000 miles (£500-£700). Coolant: Check and top up every 6 months; critical on EcoBoost models. Clutch: Manual versions can need clutch replacement at 60,000-80,000 miles (£400-£700).
Frequently Asked Questions
Is the Ford Fiesta reliable?
Yes, the Ford Fiesta Mk8 is generally reliable with a reliability score of about 72/100. The 1.0 EcoBoost requires regular coolant checks but is a solid engine. With proper maintenance and servicing, Fiestas commonly reach 120,000-150,000+ miles without major issues.

Ford ended Fiesta production in June 2023 as part of a strategic shift toward EVs and larger SUVs. The car was not profitable enough at its price point given rising manufacturing costs and changing consumer preferences toward crossovers and electric vehicles.
What's the most reliable Ford Fiesta engine?
The 1.0-litre EcoBoost 100hp is the most popular and generally reliable engine, though it needs strict coolant maintenance. The 1.5 EcoBlue diesel is extremely reliable for higher-mileage drivers. Avoid the early 2017 1.0 EcoBoost as it had more coolant pipe issues.
Is a Ford Fiesta cheap to insure?
