What you are looking at

No photograph available

We do not hold a verified photograph of the Clutch yet. We would rather show none than show a picture of a different part.

What goes wrong

The Kona 1.6T pairs with Hyundai's 7-speed dry dual-clutch transmission. The 7DCT was widely reported to shudder, vibrate, and hesitate during low-speed manoeuvring, parking, and creeping in traffic. Hyundai issued software calibration updates and eventually extended warranty coverage in several markets. The dry clutch design is less tolerant of repeated low-speed slip compared to a wet clutch DCT, and prolonged city driving accelerates wear. Clutch fork and actuator issues also documented in higher-mileage examples.

What you would notice

Shudder or vibration during slow-speed clutch engagement
Hesitation pulling away from traffic lights
Judder in car parks and low-speed reversing
Clunking or jerking when selecting drive

How to check it

Where to look. 7-speed dual-clutch transmission, mid-vehicle

Test drive extensively in stop-start traffic, reverse parking, and uphill starts.
Check for TSB/software update completion at a Hyundai dealer.
Enquire whether the transmission has been replaced or had clutch work done under warranty.

Parts involved: Clutch.

What it costs to put right

$1,800 to $4,800 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the 7DCT software calibration update been applied?”
“Any shudder or judder reported to the dealer?”
“Has the transmission been replaced or repaired?”
