Jeep Compass: JATCO CVT Belt Slippage and Failure

First-generation Jeep Compass models (MK, 2007–2012) fitted with the JATCO CVT transmission are subject to a well-documented belt-slippage and transmission failure issue. The CVT push-belt and pulley assemblies wear prematurely, particularly under load or towing. Chrysler faced class-action litigation in the USA over these transmissions. Symptoms progress from slipping under acceleration to complete loss of drive. Replacement CVT units are expensive. Many Australian used examples have been repaired, but recurrence is possible if replacement is not OEM quality.

• Transmission slip — engine revs rise without proportional vehicle acceleration
• Shuddering or vibration under moderate to hard acceleration
• Hesitation pulling away from standstill
• Transmission overheating warning
• Complete loss of drive in severe failure

1. 1

   Test drive with multiple hard acceleration runs from low speed — check for slipping (rising revs without vehicle speed increase).

2. 2

   Check for shudder between 40–80 km/h.

3. 3

   Verify CVT fluid has been serviced (CVT fluid degrades and accelerates belt wear).

4. 4

   Ask if transmission has been replaced and what unit was fitted.

Parts involved: CVT belt and pulleys.

≈A$4,140 to ≈A$8,280 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.

An estimate, converted to Australian dollars, 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.

• “Has the CVT transmission been replaced, and with what unit?”
• “Any slipping, shuddering, or hesitation under acceleration?”
• “When was the CVT fluid last changed?”

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.
