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 Hyundai-developed 8-speed wet dual-clutch transmission (8DCT) used in fifth-generation models exhibits a characteristic shudder or vibration through the drivetrain during light throttle acceleration at low speeds, typically between 20–60 km/h. The fault originates from clutch pack slip characteristics degrading as transmission fluid breaks down, combined with TCM calibration sensitivity. Hyundai issued software recalibration updates and a transmission fluid specification change, but severe cases require clutch pack replacement. The judder can be intermittent and worsen in cold weather.

What you would notice

Rhythmic shudder or vibration through floor and drivetrain during light throttle at 20–60 km/h
Shudder worse on cold mornings or after extended parking
Judder felt through accelerator pedal as well as seat
Occasional harsh or delayed gear engagement from standstill
Transmission warning light in severe cases

How to check it

Where to look. Transmission tunnel — 8-speed dual clutch gearbox unit beneath centre console

During test drive, apply very light throttle from standstill and at 20–40 km/h. Listen and feel for a rhythmic shudder or vibration through the floor and seat at low-speed light acceleration. Check service history for 8DCT fluid replacement or TCM software update. If a workshop inspection is possible: Confirm the TCM software version has been updated to the latest calibration via dealer scan.

Parts involved: Clutch.

What it costs to put right

$500 to $6,000 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 control software ever been updated by the dealer, and was a transmission fluid change carried out at the same time?”
“Does the vehicle shudder or vibrate at low speeds under light acceleration, particularly when cold?”
“Has the vehicle ever been returned to the dealer for a transmission complaint, and what was the outcome?”

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.

Hyundai Santa Fe buyer questions

Is 8dct dual clutch transmission judder at low speed serious on a Hyundai Santa Fe?

We rate it major and common on the Hyundai Santa Fe. The Hyundai-developed 8-speed wet dual-clutch transmission (8DCT) used in fifth-generation models exhibits a characteristic shudder or vibration through the drivetrain during light throttle acceleration at low speeds, typically between 20–60 km/h.

How much does it cost to fix on a Hyundai Santa Fe?

$500 to $6,000 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 Hyundai Santa Fe years are affected?

Our research records this fault on the 2019–2023 Hyundai Santa Fe. 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.
