Toyota Vitz: CVT Judder and Shudder at Low Speed
CVT Judder and Shudder at Low Speed is a common transmission fault on the Toyota Vitz on the 2005–2020 cars, and we rate it major. Putting it right costs $300 to $5,500 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 27 documented faults on the Toyota Vitz.

What goes wrong
XP90 and XP130 Yaris variants fitted with Toyota's K310 CVT develop a characteristic judder or shudder when pulling away from a standstill or during slow-speed manoeuvring. The condition is caused by degradation of the CVT fluid, which loses its friction modifier additives over time. Many owners and workshops have restored normal operation with a full CVT fluid exchange using the correct Toyota WS or manufacturer-specified fluid, but transmissions that have been run on degraded fluid for extended periods may have permanent belt-and-pulley wear. A fresh fluid change before inspection can temporarily mask the problem.
What you would notice
- Vibration or shudder felt through the drivetrain when pulling away from rest
- Shudder may be worse when cold or at light throttle openings
- Hesitation or slip sensation between 20–40 km/h
- Condition may temporarily improve then return with heat cycles
How to check it
Where to look. CVT gearbox, belt and pulley assembly, fluid circuit
Test drive from cold and perform multiple slow-speed pull-aways in a carpark.
Note any vibration or judder at low speed or when the transmission is hunting.
Check CVT fluid condition if accessible — dark or burnt-smelling fluid indicates overdue service.
Ask when CVT fluid was last changed.
What it costs to put right
$300 to $5,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has the CVT fluid ever been changed, and at what mileage?”
- “Does the car shudder or vibrate when pulling away?”
- “Has a transmission specialist ever inspected this car?”

Toyota Vitz buyer questions
Is cvt judder and shudder at low speed serious on a Toyota Vitz?
We rate it major and common on the Toyota Vitz. XP90 and XP130 Yaris variants fitted with Toyota's K310 CVT develop a characteristic judder or shudder when pulling away from a standstill or during slow-speed manoeuvring.

How much does it cost to fix on a Toyota Vitz?
$300 to $5,500 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 Toyota Vitz years are affected?
Our research records this fault on the 2005–2020 Toyota Vitz. 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.
How do I check for it before I buy?
Test drive from cold and perform multiple slow-speed pull-aways in a carpark. Note any vibration or judder at low speed or when the transmission is hunting. Check CVT fluid condition if accessible — dark or burnt-smelling fluid indicates overdue service. Ask when CVT fluid was last changed. Look here: CVT gearbox, belt and pulley assembly, fluid circuit
