Petrol, hybrid or electric — one crossover does all
The Hyundai Kona is a subcompact crossover SUV that competes with the Nissan Juke, Toyota C-HR and Peugeot 2008, standing out by offering petrol, hybrid and fully electric powertrains under one model name. It appeals to urban buyers wanting SUV styling with small-car running costs, and the Electric version became one of the most affordable long-range EVs in the UK. The second generation launched in 2023 with a bolder design and improved interior.
We track 9 known issues across the Hyundai KONA range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

OS (2017–2022) — Engine options included the 1.0 T-GDI, 1.6 GDI, 1.6 Hybrid, Electric. Our database flags 9 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Battery fire recall.
Early Kona Electric models were subject to a global recall due to manufacturing defects in the LG Chem battery cells that could cause thermal runaway and fire. The defect involves contamination during battery cell manufacturing that can cause internal short circuits. Multiple vehicle fires were reported internationally, with at least 15 confirmed cases leading to total vehicle loss. All affected vehicles received complete battery pack replacement under recall.
If the battery defect is present, thermal runaway can occur leading to vehicle fire and total loss. The vehicle should not be driven or charged if battery overheating or unusual smells are detected. All affected vehicles should have received new battery packs under recall.
Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.
The diesel particulate filter can become blocked on Kona diesel variants, particularly on vehicles used primarily for short urban journeys. The DPF requires regular motorway driving to reach the temperatures needed for automatic regeneration. Blocked filters trigger dashboard warning lights and eventually prevent the engine from starting if not addressed.
Complete DPF blockage prevents engine starting and requires professional cleaning or replacement. Driving with DPF warnings can cause permanent filter damage. Professional DPF cleaning costs £300-600, replacement costs £1,200-1,500 including labour.
Ask about the car's typical usage — short urban journeys prevent DPF regeneration. Check for DPF warning lights and ask about any previous regeneration issues. A forced regeneration at a garage costs far less than a DPF replacement.
Direct injection petrol engines develop carbon deposits on intake valves because fuel is not sprayed over the valves to clean them. The 1.0 T-GDI and 1.6 GDI engines are particularly susceptible to this issue. Carbon buildup reduces airflow, causes rough idling, and triggers misfires. Professional cleaning every 60,000-80,000 miles prevents performance degradation.
Severe carbon buildup causes misfires, reduced power, and increased fuel consumption. In extreme cases, carbon deposits can cause valve damage requiring cylinder head work. Professional walnut blasting cleaning costs £300-600 and should be performed every 60,000-80,000 miles.
Check for rough idle, hesitation or misfires during the test drive. Listen for the fuel pump priming when you turn the ignition on. Carbon buildup issues are more common on direct-injection engines — ask about intake cleaning history.
Hybrid variants show significantly elevated electronic parking brake failures at MOT testing. The system can fail to engage or disengage properly, or lose efficiency below the required 50% threshold. This is distinct from the manual handbrake mechanism and relates specifically to the electronic actuator and control module on hybrid models.
Failed electronic parking brake creates safety risk on slopes and may prevent vehicle passing MOT test. Replacement of parking brake actuator typically required. Complete system failure requires vehicle recovery as manual release may not be possible.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
The 1.6 GDI engine can develop excessive oil consumption due to faulty piston rings, requiring oil top-ups every 1000-2000 miles. This affects engine reliability and triggers warranty extensions in some markets. The issue is caused by manufacturing defects in the piston ring design that allow oil to pass into the combustion chamber.
Excessive oil consumption requires frequent expensive top-ups and indicates internal engine wear. If oil level drops too low, catastrophic engine damage can occur. Piston ring replacement typically costs £2000-3500, though some vehicles may qualify for warranty extension coverage.
Check the oil level before the engine is started. Ask the seller how often they top up the oil between services. After a test drive, check the level again and look behind the car for blue or grey exhaust smoke under acceleration.

Based on 59k real DVSA MOT tests, the Hyundai KONA fails more often than average on several items. The biggest outlier is obligatory rear fog lamp missing, or a front or... at 16x the fleet average, followed by emissions failure (9x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Hyundai KONA MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.

The Hyundai KONA has some well-documented weak points, including 1 safety-critical issue that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. 2020-2022 models are the sweet spot, combining improved reliability over early cars, updated safety tech, and strong residual values. The 64kWh Electric from 2020 onwards offers a genuine 259-mile real-world range and can be found from around £12,000-£15,000 used.
