⚠️ Common problems of the Dacia CVT transmission

Although it has improved over the years, the CVT transmission has some typical critical issues, especially if neglected.

1. Slippage during acceleration

• Increased engine RPM without adequate thrust

• Annoying on climbs or during overtaking

• Symptom of variator or fluid wear

2. Delayed response and slow downshifting

• Feeling of "void" when accelerating or decelerating rapidly

• More evident in urban traffic or with heavy loads

3. Metallic noises or constant hum

• Especially when cold or starting up

• Possible sign of degraded oil or abnormal friction

4. Jerking or vibrations when starting

• If neglected, they can escalate into serious breakdowns

• Often solvable with a simple transmission service

🛠️ Why do these defects occur?

Inadequate maintenance is the main cause of problems:

• ❌ Transmission fluid is not changed regularly

• ❌ Generic or incompatible lubricants are used

• ❌ The car is used heavily (climbs, towing, sporty driving)

• ❌ Many think the CVT is "maintenance-free" → ERROR
