Credov's researched list of the 4 faults the Hyundai Kona EV is known for (2018–2021), 4 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Ask for Hyundai paperwork showing the battery pack was replaced or updated, and check it will charge past 90%.
Why it matters: A battery fire in a parked or charging car can destroy the car and the building around it; a car that has had its new pack is worth more.
What to look for: Watch for a Check EV System or inverter coolant warning on the drive, and check the inverter coolant level.
Why it matters: Losing drive power at speed is dangerous, and a power control unit or traction motor is an expensive part out of warranty.
What to look for: Watch for brake or ABS warnings, and brake firmly from low speed, checking the pedal feels firm and assisted.
Why it matters: Reduced braking power lengthens stopping distances and can cause a crash.

What to look for: On a quiet road, go on and off the accelerator repeatedly, listening for clicks, knocks or whine from the front.
Why it matters: Caught early it can be a bearing and seal overhaul; left, it can need a new reduction gearbox or motor.
Typical repair: NZ$2,000–NZ$8,000 in New Zealand · A$2,060–A$8,240 in Australia
