On the 2008-2024 Renault Koleos, the Jatco CVT in the Koleos develops judder, slipping, and overheating symptoms. The CVT belt and pulleys wear under the heavier SUV load, and the fluid degrades more rapidly than in lighter applications.
Common Symptoms
Judder on acceleration
Slipping sensation
CVT whine
Overheating warning
How to Fix
Perform a complete CVT fluid exchange with genuine Renault NS-2 or NS-3 fluid. Replace the CVT belt and pulleys if slip is confirmed. Update CVT control module software.

On the 2009-2020 Renault Koleos, the Jatco-sourced X-Tronic CVT used in the Koleos is the single most reported failure point. Owners report gear slipping, shuddering on shifts, hesitation under acceleration, and the engine flaring to high RPM in Drive (belt slip / loss of hydraulic pressure), typically after around 100,000 km. A known contributing cause is the transmission oil cooler allowing engine coolant to mix into the transmission fluid, contaminating and destroying internal components. Complete transmission replacement is common and expensive.
Common Symptoms
Slipping or jerking during acceleration
Shuddering or shaking when shifting
High RPM / engine flaring in Drive
Delayed gear engagement
Grinding or whining noise from transmission
Hesitation under load
How to Fix
Replace CVT fluid every ~60,000-80,000 km (sooner for heavy city/stop-start use) with the correct Renault/Jatco NS-3 spec fluid, and inspect for coolant cross-contamination at the cooler. Early intervention (fluid + cooler) can prevent failure; once the belt/valve body is damaged, a transmission rebuild or replacement is required.
