Nissan Leaf Named the UK’s Most Reliable Electric Car – But Here’s the Bigger Picture on EV Repairs
If you’re thinking of switching to electric, you probably expect fewer breakdowns and lower running costs compared to petrol or diesel cars. And while that can be true, new research from Warranty Solutions Group shows there’s more to the story – especially when it comes to repair costs.
After analysing 800 EV warranty claims from across the UK, we’ve crowned the Nissan Leaf as the most reliable electric vehicle in the country. But the data also uncovers some surprising facts about which EVs go wrong the least, which are the most expensive to fix, and what that means for your wallet.
The Reliability Winners
1️⃣ Nissan Leaf – Claim rate: 3.06%The Leaf’s low fault rate and proven durability make it a safe bet for electric driving. Its simple, well-tested design means fewer headaches and more miles between repairs.
2️⃣ MG ZS EV – Claim rate: 4.76%This budget-friendly electric SUV not only ranked second for reliability but also had the lowest average repair cost in our study – just £225.90. That’s great news for first-time EV owners and families looking for affordable peace of mind.
3️⃣ Audi E-Tron – Claim rate: 5.56%A luxury SUV that proves premium can still mean dependable. With an average repair bill under £310, it blends comfort, tech, and reassuringly low fault rates.

The More Problematic Models
At the other end of the scale, a few models had alarmingly high claim rates:
- Tesla Model S – 50% claim rate, £703.50 average repair cost
- Volkswagen E-Golf – 33.33% claim rate
- Kia E-Niro – 25% claim rate
- Jaguar I-Pace – 21.43% claim rate, £1,353.69 average repair cost
The Vauxhall Corsa Electric deserves a special mention – not for reliability, but for expense. Despite a mid-range claim rate (9.68%), its average repair bill is a wallet-draining £2,261.88.
EVs vs Petrol & Diesel – The Real Cost of Repairs
Here’s where things get interesting:
- Claim rates are almost identical – EVs at 13.21%, petrol/diesel at 13.74%.
- Repair costs tell a different story – EVs average £858.50 per claim, compared to £668.45 for petrol/diesel cars.
That’s because EVs use specialist parts, require highly trained technicians, and often involve complex repairs – even if they have fewer moving parts overall.
The Big-Ticket Repairs
Some repairs can be eye-watering. In the past year, WSG has paid out for:
- £6,219.90 – Vauxhall Corsa SRI Nav Premium (electric drive fault)
- £5,495.51 – Mini Countryman Cooper S E All4 Classic (inverter/DC converter fault)
- £4,658.78 – Vauxhall Grandland X Elite Nav (drive shaft fault)
Luxury EVs like the Jaguar I-Pace and Porsche Taycan also appeared in the top 10 most expensive repairs, proving premium tech can carry premium repair bills.

The Most Common EV Faults
The top issues affecting EVs include:
- Charger ports – Most common fault (3.01% claim rate), usually affordable to fix (£119.96 average)
- Tyre Pressure Monitoring System (TPMS) – £132.67 average
- On-board chargers – Often £1,000+ per repair
- Air conditioning compressors – Also over £1,000 on average
- 12v batteries – £193.80 average
Even seemingly small components can result in big bills when specialist EV parts are involved.

What This Means for EV Owners
Warranty Solutions Group’s Operations Director, Martin Binnee, sums it up:
“While EVs and petrol/diesel cars break down at similar rates, EV repairs are more expensive. Buyers need to factor that into the total cost of ownership – not just fuel savings. Comprehensive, EV-specific warranty cover isn’t optional anymore; it’s essential.”
As the EV market grows, understanding these costs – and protecting yourself against them – will be key to enjoying stress-free electric motoring. Whether you’re going for a budget-friendly MG ZS, a rock-solid Nissan Leaf, or a luxury Audi E-Tron, the right warranty can keep you covered from charger port to battery pack.
