⚠️ Common Dacia CVT gearbox problems

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

1. Slipping during acceleration

• Increased engine revs without adequate thrust

• Annoying on climbs or when overtaking

• Symptom of variator or fluid wear

2. Delays in response and slow scaling

• Feeling of "emptiness" when accelerating or decelerating rapidly

• More noticeable in city traffic or with heavy loads

3. Metallic noises or constant humming

• Especially when cold or starting

• Possible sign of degraded oil or abnormal friction

4. Jerking or vibrations when starting

• If neglected, they can degenerate into serious failures

• Often solvable with a simple gearbox service

🛠️ Why do these defects occur?

Improper maintenance is the main cause of problems:

• ❌ The gearbox oil is not changed regularly

• ❌ Generic or incompatible lubricants are used

• ❌ The car is used in a strenuous manner (hills, towing, sporty driving)

• ❌ Many people think that the CVT is “maintenance-free” → ERROR
