6 Most Common Nissan Leaf Problems

These are the faults most frequently seen on the Nissan Leaf by UK garages — ranked by how commonly they occur and what they cost to fix.

1
Battery Degradation (24 kWh / 30 kWh MK1)
High Priority
The original 24 kWh and 30 kWh Leaf batteries degrade significantly over time — particularly on cars that have been frequently rapid charged or used in hot climates. Real-world range on a 2013 Leaf may now be 50–70 miles. Check the battery health bars on the dashboard before buying any MK1 Leaf.
💷 Typical repair cost: £2,500–£6,000 (replacement)
2
No Active Battery Cooling (MK1)
High Priority
The MK1 Leaf uses passive air cooling for its battery — unlike most other EVs. This makes it more susceptible to degradation from heat and frequent rapid charging. An inherent design limitation.
💷 Typical repair cost: N/A — design characteristic
3
Charging System Faults
Watch
Both MK1 and MK2 Leafs can develop AC and DC charging faults — failure to charge, slow charging or error messages at public chargers.
💷 Typical repair cost: £200–£1,500
4
12V Auxiliary Battery Failure
Watch
The 12V auxiliary battery fails every 3–5 years on all Leaf variants — causing random electrical faults and inability to start the car.
💷 Typical repair cost: £100–£200
5
40 kWh Battery Degradation (MK2)
Watch
MK2 Leafs with the 40 kWh battery are now showing some range reduction on higher-mileage examples — though significantly less than MK1 cars.
💷 Typical repair cost: £1,500–£4,000
6
Rear Brake Squeal
Low Priority
Rear brake squeal after inactivity is very common on Leafs — surface rust on rear discs.
💷 Typical repair cost: £0–£300
