7-speed dry dual-clutch (7DCT) judder and hesitation (1.6 turbo) is a common transmission fault on the Hyundai Kona on the 2017–2023 cars, and we rate it major.

What you are looking at

No photograph available

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

What goes wrong

The 1.6 turbo Kona uses Hyundai's dry-clutch 7DCT, which is prone to shudder and judder when pulling away, jerky 1-2 shifts and hesitation at intersections, especially in stop-start traffic and on hills. Hyundai issued TSB 22-AT-007H covering DCT shudder, and Hyundai Australia also recalled thousands of DCT-equipped vehicles for a fail-safe programming fault (campaign 21D155 on related models) that could cause loss of drive. Worn clutch packs need replacement and repeated heat abuse shortens their life significantly.

What you would notice

Shudder or vibration when pulling away from a stop
Jerky low-speed shifts, especially 1st to 2nd
Hesitation then lurch when accelerating from a junction
Rolling-back feel on hill starts

How to check it

Where to look. Transmission, under the car between engine and front wheels

Test drive in traffic conditions: do repeated stop-start take-offs and a hill start.
Any shudder through the floor on take-off is the clutch.
Check with a Hyundai dealer (using the VIN) that all DCT recalls and software updates have been done.

Parts involved: Clutch, Turbocharger.

What it costs to put right

$2,000 to $4,500 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 DCT clutch ever been replaced?”
“Have all outstanding recalls and TSB software updates been completed?”
“Is the car mostly used in city or open-road driving?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.
