What goes wrong
The current Koleos is petrol-only with a CVT, and the transmission is the main durability worry: owners report jerky acceleration or hesitation off the throttle and a whining or humming noise, caused by overheated old fluid and internal belt/pulley wear, worst in stop-start city driving. Keeping the fluid fresh matters. A CVT that hesitates or whines is a large repair, so test it thoroughly and value service history.
What you would notice
- Hesitation or jerk when you press the throttle
- Whine or hum that rises with speed
- Shudder under light acceleration
- Delayed drive from a stop
How to check it
Where to look. CVT transmission at the front of the car
Drive it in stop-start conditions and on an on-ramp; feel for hesitation, jerk or shudder and listen for a whine or hum.
Ask when the CVT fluid was last serviced.
Any flaring of revs without matching acceleration is a warning.
What it costs to put right
$3,000 to $7,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “When was the CVT fluid last changed?”
- “Does it ever hesitate, jerk or whine when accelerating?”
