Paint chipping and trim rattles.
- Typically appears
- Age-related
- What to inspect
- Inspect paint and listen for rattles.
ElectricalLow
Infotainment glitches.
- Typically appears
- Age-related
- What to inspect
- Test the screen and CarPlay.
ElectricalMedium
Parasitic drain leading to a flat 12V battery, causing non-start conditions.
- Typically appears
- 20,000-40,000 miles
- What to inspect
- Connect a multimeter to the 12V battery terminals with the ignition off. Look for a voltage drop below 12.4V, and check the OBD port for aftermarket dongles causing the drain.
Engine (1.0 T-GDi)Medium
Metallic rattling or buzzing noise from the turbocharger wastegate actuator linkage.
- Typically appears
- 40,000-60,000 miles
- What to inspect
- Open the bonnet and have an assistant lightly rev the engine from idle. Listen closely to the front heat shield area for a distinct metallic rattle as the revs drop.
SuspensionLow
Knocking noise from the rear over uneven surfaces and poor ride quality due to leaking rear shock absorbers.
- Typically appears
- 30,000-50,000 miles
- What to inspect
- Shine a torch into the rear wheel arches and visually inspect the shock absorber bodies for heavy oil misting or fresh fluid leaks running down the casing.
BrakesMedium
Premature rear brake pad wear and binding calipers, leading to squealing and scored discs.
- Typically appears
- 25,000-45,000 miles
- What to inspect
- Visually inspect the rear brake discs for heavy scoring or rust lips. After a brief test drive, check if one rear alloy wheel radiates significantly more heat than the others.

Build my inspection planFrequently asked questions
Is the Kona reliable?
Broadly yes; monitor oil consumption on the 2.0 petrol engine.
Does the Kona burn oil?
Some 2.0 Nu engines consume oil; check the level between changes.
Any Kona recalls?
EV battery recalls applied to the electric version; petrol cars have fewer major campaigns.
What should I look out for on the 1.6 GDi Hybrid models?
The 1.6 GDi Hybrid system is generally robust, but check the transition between electric and petrol power during a test drive. It should be seamless. Jerkiness often points to software issues requiring a dealer update, or occasionally, dual-clutch actuator wear. Ensure the hybrid battery cooling fan filter isn't blocked.
When is the timing belt due for replacement?
The majority of first-generation Kona engines, including the popular 1.0 T-GDi, 1.6 T-GDi, and 1.6 GDi Hybrid, use a timing chain rather than a timing belt. These chains are designed to last the life of the vehicle, provided the car receives regular, high-quality oil changes to prevent tensioner failure.
Are there any specific checks for the Blind Spot Collision Warning system?
Yes, the radar sensors are located behind the rear bumper corners and are highly susceptible to water ingress or damage from minor rear-end shunts. During your forecourt check, ensure the warning lights in the wing mirrors illuminate briefly on startup and check the rear bumper for poor paint repairs.
