Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Hybrid Battery Health

Medium risk

After 6 years, hybrid battery capacity may have reduced. A full replacement costs £2,000-£4,000, though reconditioning is cheaper at £500-£1,500.

Inverter and Power Electronics

Low risk

The inverter converts DC to AC for the electric motor. Failures are expensive (£1,500+) but relatively rare. Listen for unusual buzzing sounds.

Regenerative Braking

Medium risk

Brake discs can corrode from reduced use (the electric motor handles most braking). Surface rust is normal but deep pitting needs attention.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
