Subaru Impreza: Lineartronic CVT shudder and hesitation (GJ/GP, GK/GT)

Lineartronic CVT shudder and hesitation (GJ/GP, GK/GT) is a common transmission fault on the Subaru Impreza on the 2011–2019 cars, and we rate it major. Putting it right costs $1,500 to $7,000 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 44 documented faults on the Subaru Impreza.

What you are looking at

No photograph available

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

What goes wrong

CVT Imprezas from the GJ/GP generation onward share the TR580 Lineartronic's low-speed shudder, hesitation off the line, and occasional torque converter lock-up clutch judder. Subaru's US extended CVT warranty (10yr/100k miles) covered 2012-2015 Imprezas — a tacit admission — but expired and never applied to NZ-new or JDM cars. Old fluid makes it worse; a service helps early cases, while a failed torque converter or CVT replacement is a four-figure job on a car that may only be worth five.

What you would notice

Judder pulling away, like a slipping clutch
Hesitation then surge from a stop
Whine rising with road speed
AT Oil Temp light flashing on start-up

How to check it

Where to look. Transmission — felt through the car when pulling away

Do repeated stop-start pull-aways on the test drive, including on a slight uphill — that is where judder appears first. Hold steady light throttle at 50 km/h and feel for vibration. Ask when CVT fluid was last changed. Any AT Oil Temp flash or check-engine light needs a scan before money changes hands.

Parts involved: Torque converter, Clutch.

What it costs to put right

$1,500 to $7,000 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 CVT fluid been serviced?”
“Any judder or hesitation from a stop?”
“Has the CVT or torque converter been replaced?”

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.

Subaru Impreza buyer questions

Is lineartronic cvt shudder and hesitation (gj/gp, gk/gt) serious on a Subaru Impreza?

We rate it major and common on the Subaru Impreza. CVT Imprezas from the GJ/GP generation onward share the TR580 Lineartronic's low-speed shudder, hesitation off the line, and occasional torque converter lock-up clutch judder. Subaru's US extended CVT warranty (10yr/100k miles) covered 2012-2015 Imprezas — a tacit admission — but expired and never applied to NZ-new or JDM cars.

How much does it cost to fix on a Subaru Impreza?

$1,500 to $7,000 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 Subaru Impreza years are affected?

Our research records this fault on the 2011–2019 Subaru Impreza. 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.
