The Nissan Leaf was the world's first mass-market electric car and remains one of the most common EVs on UK roads. The MK1 (2011–2017) and MK2 (2018–present) are both still common. Early examples with the 24 kWh battery are now showing significant range degradation — a critical buying consideration.

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.
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)
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
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
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
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
Rear brake squeal after inactivity is very common on Leafs — surface rust on rear discs.
💷 Typical repair cost: £0–£300

Nissan Leaf — MOT Tips
EV high-voltage warning lights must be clear for MOT. All charging systems must operate. 12V auxiliary battery health is critical — a failed 12V battery can prevent the car from starting on MOT day. Check battery health bars on any MK1 Leaf.

Nissan Leaf Tyres
Most Nissan Leaf models run 195/65 R15 or 205/55 R16 or 215/50 R17 depending on trim level and year. Always check the placard inside the driver's door for the exact size for your vehicle.
Summary
The Leaf is an important used EV — but battery health is everything. For MK1 examples, always check the battery capacity bars on the dashboard and do a real-world range test before buying. The MK2 40 kWh and 62 kWh variants are much stronger used buys.
