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 YB-generation Rio paired with Hyundai-Kia's 7-speed dual-clutch transmission (D-DCT, code 7DCT300) exhibits clutch judder and shudder during low-speed engagement below approximately 30 km/h, particularly when pulling away from rest on inclines or in traffic. The wet clutch packs develop chatter due to a combination of clutch pack material wear and software calibration. Kia released multiple TSBs and software updates, but hardware replacement of the clutch pack is often the definitive fix. This mirrors the wider Hyundai-Kia DCT complaint wave that triggered investigations in South Korea and the US.

What you would notice

Vibration or shudder felt through the seat and floor during low-speed pull-away
Jerking or hunting when creeping in stop-start traffic
Clunk or hesitation when transitioning from drive to reverse at low speed
Transmission warning light in severe cases with fault code P0726 or related clutch slip codes

How to check it

Where to look. Transmission tunnel, dual-clutch gearbox unit mounted to front of engine

During a test drive, pull away slowly from rest multiple times, including on a slight hill. Note any vibration, shudder, or jerking through the drivetrain at low speed. Engage and disengage the accelerator gently in slow-moving traffic and check for lurching. Ask for any TCU software update history from Kia.

Parts involved: Clutch.

What it costs to put right

$1,500 to $3,800 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 transmission ever shuddered or juddered when pulling away, and has Kia looked at it?”
“Has the TCU software been updated at a Kia dealer — is there a record of that?”
“Has the dual-clutch pack ever been replaced under warranty or out of pocket?”

Now check the Kia Rio you are actually looking at

Everything above is true of the model, and it is free. 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. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Kia Rio buyer questions

Is yb 7-speed dct clutch pack judder and shudder serious on a Kia Rio?

We rate it major and common on the Kia Rio.

How much does it cost to fix on a Kia Rio?

$1,500 to $3,800 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Kia Rio years are affected?

Our research records this fault on the 2017–2023 Kia Rio. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
