What to check before buying a 2013 I40
Before buying a 2013 Hyundai I40, focus on the areas it most often fails on. Brakes accounted for 8.8% of tests for this year.
- Brakes (8.8% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Lighting & signalling (8.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Steering (7.4% of tests): Play, leaks or worn track rod ends — affects handling and is a safety item. Typical repair: £150–£500.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
