Every generation rated
Solid and reliable but now aged. 1.2 petrol is simple and dependable. 1.4 CRDi diesel economical for higher mileage. No significant known faults. Getting old at the lower end of the range — buy 2017+ only for a reasonable specification.
€7,000–€14,000
A significant step up. New platform, more refined, much better interior quality. 1.0 T-GDi 100hp is the outstanding engine choice — turbocharged, economical, and characterful. 48V mild hybrid available on some variants for lower motor tax. Hyundai 5-year warranty may still be active on 2020+ examples.
€15,000–€22,000
✅ No Major Warning — One of Ireland's Safest Small Car Purchases
The Hyundai i20 has no significant known reliability issues across either generation. The main watchpoint on the Mk3 is confirming the remaining Hyundai 5-year warranty with Hyundai Ireland before purchase — it may still have meaningful coverage. The 1.0 T-GDi should be checked for any signs of timing chain wear on very early 2020 examples, but this is uncommon.
Best engines to buy
1.0 T-GDi 100hp (Mk3, 2020+) — Top Pick
The outstanding used i20 engine. Hyundai's turbocharged 1.0 T-GDi delivers real-world economy of 5.5–6.5L/100km with genuine performance — 0–100km/h in under 11 seconds. The three-cylinder is characterful and smooth for its size. Available with manual or iMT (intelligent manual transmission with no clutch pedal — unusual but reliable). No significant known issues. The definitive Mk3 i20 engine choice.
1.2 MPi 84hp (Mk2 and Mk3) — Budget Petrol
The naturally-aspirated 1.2 is simple, cheap to run, and entirely dependable. Economy of 6.5–7.5L/100km. Lacks motorway confidence but perfectly adequate for city and suburban use. The right choice for buyers wanting the lowest possible running costs and no complexity whatsoever. Widely available across both generations.
1.4 CRDi 90hp (Mk2) — Diesel Pick
Economical at 4.5–5.5L/100km and well proven in the i20. Timing belt every 120,000km — verify records. DPF health is the check on any diesel i20 used for short journeys. Worth considering only for buyers covering over 20,000km/year. For lower mileage, the 1.0 T-GDi petrol is a better all-round choice.
1.0 T-GDi 48V Mild Hybrid (Mk3) — Efficiency Option
The 48V mild hybrid system reduces fuel consumption by around 5–10% over the standard 1.0 T-GDi. More meaningfully for Irish buyers, the lower CO2 emissions qualify for a reduced motor tax rate. The mild hybrid system is simple and adds minimal complexity compared to a full hybrid. An excellent choice if available within budget.

Is the Hyundai i20 better than the Ford Fiesta?
