All 2 Known Issues
On the 2013-2024 Renault Zoe, the Zoe battery pack experiences capacity degradation that reduces usable range over time. Early 22kWh packs are most affected, with some owners reporting 20-30% capacity loss within 5 years. Frequent rapid charging and high ambient temperatures accelerate degradation.
Common Symptoms
- Reduced range
- Faster charge depletion
- Battery health below 80%
- Range estimate drops significantly
How to Fix
Monitor battery health via the Renault Z.E. app or OBD diagnostic tool. Avoid frequent rapid charging and keep charge between 20-80% for daily use. Battery lease customers can request replacement when capacity drops below 75%.
On the 2013-2024 Renault Zoe, the Zoe Chameleon charger experiences intermittent charging failures, refusing to start or stopping mid-charge. The on-board charger module overheats during high-power AC charging, and connector pin corrosion causes communication errors.
Common Symptoms
- Charging fails to start
- Charging stops mid-session
- Charger error light
- Reduced charging speed
How to Fix
Clean the charging port connector pins. Check for software updates to the Chameleon charger module. Replace the on-board charger unit if it consistently overheats or refuses to charge.
