Hyundai Kona Common Faults in the UK

OS 2017–2023 and SX2 2023–on — small crossover SUV, sold as petrol, hybrid and electric. Updated 6 October 2026.

This guide covers the OS 2017–2023 and SX2 2023–on. For any other version of the Kona, see how to check any car for known faults.

The Hyundai Kona’s risk depends on the powertrain more than the year. On the first-generation Kona Electric DVSA lists three battery recalls, the newest (R/2026/128) covering cars built January 2018 to July 2023, so check the recall record before you buy. Across the Kona range (DVSA’s MOT table does not split by fuel) the Kona passes the MOT level with or above cars of the same age. Hyundai UK gives new cars five years with no mileage limit, and eight years or 100,000 miles on the high-voltage battery.

Largest DVSA recall for the Kona: R/2026/128, 25,056 vehicles — Some vehicles fitted with a high voltage battery may have internal cell voltage deviation.

MOT pass rate — official DVSA data

90.3% of Hyundai Konas pass the MOT first time, 1.2 points better than the national average for cars of the same age (89.1%). Counted from 6,358 DVSA tests on cars registered 2018–2022; a pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.

Source: DVSA MOT Anonymised Data 2025 (Open Government Licence v3.0). Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a first-time pass; DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Testing in Northern Ireland is run separately by the DVA under its own rules. Compared against cars of the same registration years, because pass rates otherwise mostly measure how old a model's surviving fleet is.

Asking prices — on Autoza
No figure shown
We show one only when at least 10 cars qualify.
Road Tax (UK) — VED, from the second year
£200/yr standard rate
£200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. A car registered from April 2017 with a list price over £40,000 when new adds the £440/year Expensive Car Supplement in years 2–6 (£640 in all). Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates). Electric versions: one first registered from 1 April 2025 pays the £440/year supplement in years 2–6 only if it listed at over £50,000 new; one registered before then never does, whatever it cost.
Fuel Economy — sourced figures only
What Car? recorded 250 miles or more of real-world range from the 64 kWh Kona Electric (its October 2025 update); we have no sourced real-world figure for the petrol or hybrid versions, whose official figures depend on the engine.
Insurance
Insurance group depends on the engine and trim, so get a quote for the exact registration before you buy.

No asking-price figure is shown: we give the median and middle 80% of asking prices only when at least 10 cars on Autoza qualify — here, Hyundai Kona cars registered from 2017. The road tax line comes from GOV.UK's vehicle tax rate tables (2026/27 rates). The fuel economy tile names the source it rests on or says there is no sourced figure, and the insurance tile gives no figure. We do not publish a UK price index, and no figure here should be quoted as one.

Best and worst years to buy

We name a year as a best or worst buy only where the DVSA MOT table further down does not rate it the other way.

Best Years
2021, 2022

2021 and 2022 registrations sit level with all cars registered those years on DVSA’s MOT table. Electric Konas built from April 2020 are outside the earlier battery recalls R/2020/308 and R/2021/087 (both end with cars built March 2020), and cars built from December 2020 are outside the braking-software recall R/2020/382. They are not recall-free: R/2026/128, a battery-management software update for 25,056 vehicles, runs to cars built July 2023. This is a reading of recall dates and MOT results, not a ranking of build quality.

Worst Years
No standout bad year

No year is named. DVSA’s MOT table rates 2018 and 2019 registrations above all cars registered those years and 2020 to 2022 level, and the Kona Electric’s battery recalls run across every first-generation build (January 2018 to July 2023) rather than one year. On an electric Kona the question is whether the recall work was done on that car, not which year it is from. Early cars have two small recalls of their own, which DVSA files under plain Kona with no fuel type: R/2019/001 (built 9 May to 19 December 2018) and R/2019/115 (built 20 April 2017 to 11 September 2018).

Known faults — Hyundai Kona OS 2017–2023 and SX2 2023–on

How to read this list. Items marked Safety recall are DVSA safety recalls, shown with DVSA’s own reference. Whether a particular car is affected depends on when it was built: check it by registration through GOV.UK’s vehicle recall check. Items marked Warranty terms state what the manufacturer’s UK warranty or battery guarantee covers. They are not faults and not service actions: they carry no severity and no repair cost. Everything else in this list is owner-reported: what the UK publication named on each card reports from its owner surveys and tests. Those are worth checking on a viewing, but we hold no count of how many cars have each one, other than any survey share a card itself quotes. Treat an owner-reported item as a question to ask, not a fault this car has.

Electrics — warning lights and battery-related faults (Kona Electric)

Owner-reported · frequency unknownModerate
Symptoms
What Car? readers reported faulty warning lights and battery-related problems on the Kona Electric, with some cars off the road for a long time because parts were slow to arrive. Feedback on dealer service was mixed.
Years affected
2018–2023 Kona Electric
What to check before buying
Start the car and wait for the self-test: no warning light should stay on. Ask for the invoices for any electrical or battery work and which software updates a dealer has applied, and charge it fully once on the seller’s charger before you agree a price.

Cover — five-year unlimited-mileage warranty and eight-year battery cover

Warranty terms
Symptoms
Not a fault. Hyundai UK states a five-year unlimited-mileage warranty on new cars, eight years or 100,000 miles on the high-voltage batteries of the Kona Electric and Hybrid, and covers the 48-volt battery of a mild-hybrid car under the five-year warranty.
Years affected
All, counted from first registration
What to check before buying
Hyundai states plainly that "an invalidated warranty cannot be revalidated by transfer of the vehicle". A gap in servicing before you bought the car cannot be cured by the sale, so the service history matters more here than the age does — and because the mileage is unlimited, the history is effectively the only thing that can have ended the cover early. Work out the end date from the registration date on the V5C rather than from the model year, and ask a Hyundai dealer to confirm what remains for the VIN.

Hyundai Kona MOT results by year and mileage

Measured from DVSA’s own MOT test records for tests carried out in 2025, not from owner reports.

By registration year

Against all cars registered in the same year, the MOT pass rate for the Kona was higher in 2 and level in 3 of the 5 registration years from 2018 to 2022 with enough tests to measure. The widest gap above is 2018 registrations: 90.7% against 84.5%.

Only a major or dangerous defect fails an MOT. A minor defect is recorded on the certificate and the car still passes, and an advisory is not a failure at all.

We don’t give a recall count for the Hyundai Kona: whether a recall applies depends on the individual car. Check the one you are looking at by entering its registration on GOV.UK’s vehicle recall checker, and see how to check a car for known faults for the other free checks.

Source: DVSA MOT Anonymised Data 2025 (Open Government Licence v3.0). Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a first-time pass; DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Odometer readings below 100 or above 400,000 miles are discarded as misreadings, and cars under three years old are excluded because no MOT is yet due. Sampled from nine months of 2025 (January, February, April, May, July, August, September, October and November). Testing in Northern Ireland is run separately by the DVA under its own rules. Registration years shown are cars 3 to 12 years old when tested; the smallest rests on 708 tests. A gap is called level when it is under one percentage point or inside the 95% sampling margin for that number of tests.

Who this car suits — and who should look elsewhere

Recommended for

Buyers who want a compact SUV and will check the recall record on the car, particularly an electric Kona, before agreeing a price.

Not recommended for

Anyone buying a first-generation Kona Electric without proof that the battery recalls were carried out, or counting on warranty cover without working out its end date from the registration.

Hyundai Kona: questions buyers ask

What are the most common faults on a used Hyundai Kona in the UK?

The Hyundai Kona’s risk depends on the powertrain more than the year. On the first-generation Kona Electric DVSA lists three battery recalls, the newest (R/2026/128) covering cars built January 2018 to July 2023, so check the recall record before you buy. Across the Kona range (DVSA’s MOT table does not split by fuel) the Kona passes the MOT level with or above cars of the same age. Hyundai UK gives new cars five years with no mileage limit, and eight years or 100,000 miles on the high-voltage battery.

What is the best year to buy a used Hyundai Kona in the UK?

Best-buy years: 2021, 2022. 2021 and 2022 registrations sit level with all cars registered those years on DVSA’s MOT table. Electric Konas built from April 2020 are outside the earlier battery recalls R/2020/308 and R/2021/087 (both end with cars built March 2020), and cars built from December 2020 are outside the braking-software recall R/2020/382. They are not recall-free: R/2026/128, a battery-management software update for 25,056 vehicles, runs to cars built July 2023. This is a reading of recall dates and MOT results, not a ranking of build quality.

What years of Hyundai Kona should I avoid in the UK?

No specific year of the OS 2017–2023 and SX2 2023–on Hyundai Kona is generally avoided. No year is named. DVSA’s MOT table rates 2018 and 2019 registrations above all cars registered those years and 2020 to 2022 level, and the Kona Electric’s battery recalls run across every first-generation build (January 2018 to July 2023) rather than one year. On an electric Kona the question is whether the recall work was done on that car, not which year it is from. Early cars have two small recalls of their own, which DVSA files under plain Kona with no fuel type: R/2019/001 (built 9 May to 19 December 2018) and R/2019/115 (built 20 April 2017 to 11 September 2018).

How much does a used Hyundai Kona cost in the UK in 2026?

This page gives no figure at the moment: Autoza quotes asking prices only when at least 10 qualifying cars are advertised with a price — here, Hyundai Kona cars registered from 2017. Prices vary by mileage, region and trim, so compare several adverts of the same year and mileage band before negotiating.

What is the road tax (VED) on a Hyundai Kona in the UK?

Annual road tax (VED): £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. A car registered from April 2017 with a list price over £40,000 when new adds the £440/year Expensive Car Supplement in years 2–6 (£640 in all). Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates). Electric versions: one first registered from 1 April 2025 pays the £440/year supplement in years 2–6 only if it listed at over £50,000 new; one registered before then never does, whatever it cost.

What real-world fuel economy does a Hyundai Kona achieve on UK roads?

What Car? recorded 250 miles or more of real-world range from the 64 kWh Kona Electric (its October 2025 update); we have no sourced real-world figure for the petrol or hybrid versions, whose official figures depend on the engine.

How does a Hyundai Kona compare to its rivals?

Strong alternatives in the UK: Kia Niro, Volkswagen T-Roc, Renault Captur, Nissan Juke. Choose based on dealer network in your area, parts availability, and your priorities (running cost vs. cabin quality vs. badge).

Who is the Hyundai Kona most suitable for?

Buyers who want a compact SUV and will check the recall record on the car, particularly an electric Kona, before agreeing a price.

Who should NOT buy a Hyundai Kona?

Anyone buying a first-generation Kona Electric without proof that the battery recalls were carried out, or counting on warranty cover without working out its end date from the registration.

Are there safety recalls on the Hyundai Kona?

DVSA lists 9 safety recalls for the Hyundai Kona that this guide shows or names, the largest first: R/2026/128 (25,056 vehicles, built between 24 January 2018 and 15 July 2023): Some vehicles fitted with a high voltage battery may have internal cell voltage deviation; R/2020/382 (12,835 vehicles in the whole recall, built between 24 January 2018 and 18 November 2020): If an abnormality is registered within the ieb system that may illuminate the malfunction indicator lamp on the vehicle cluster braking performance may be reduced; R/2024/154 (2,304 vehicles, built between 21 March 2023 and 5 January 2024): A risk of electrical short circuit within the engine compartment during a vehicle collision. Whether a particular car is affected depends on its build date and VIN, so check its registration on GOV.UK (gov.uk/check-vehicle-recall) before you buy.

Is the Battery — cell voltage deviation (Kona Electric) on the Hyundai Kona a serious problem?
