Buying a used Hyundai i40: what to check

These checks follow the Hyundai i40’s own MOT record: the areas it fails on most often, and how that changes as the car gets older. None of them replaces a mechanic’s inspection, but they tell you where to look first.

The biggest drop in pass rate for the Hyundai i40 comes between 6–10 years and 10–15 years old, from 81.2% to 70.1%. If you are looking at one in or just past that range, read its MOT history closely.

By mileage, the steepest fall is from 0–30,000 mi to 30,000–60,000 mi: 92.1% down to 85.2%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.

  1. 1. Brakes

    Recorded in 44.1% of failed Hyundai i40 MOTs. 16.4% of tests at 10–15 years failed on brakes, against 5.0% at 3–6 years.

    On the test drive, the car should stop straight without pulling or juddering, and the handbrake should hold it on a slope. Look through the wheels for scored or heavily lipped discs.

  2. 2. Lights and electrics

    Recorded in 31.1% of failed Hyundai i40 MOTs. 11.4% of tests at 10–15 years failed on lights and electrics, against 4.1% at 3–6 years.

    Walk round with the lights on: headlights (dipped and main), indicators, brake lights, fog light and number-plate lamp. Check the dashboard warning lights come on with the ignition, then go out once the engine starts.

  3. 3. Tyres

    Recorded in 28.7% of failed Hyundai i40 MOTs. 8.5% of tests at 10–15 years failed on tyres, against 4.0% at 3–6 years.

    Check tread depth across the whole width of every tyre, including the inner edge. Uneven wear can point to alignment or suspension problems. Look for cuts and bulges in the sidewalls.

  4. 4. Suspension

    Recorded in 22.4% of failed Hyundai i40 MOTs. 10.5% of tests at 10–15 years failed on suspension, against 1.4% at 3–6 years.

    Listen for knocks over bumps and speed humps, and check the car sits level. Push down on each corner: it should settle rather than keep bouncing.

  5. 5. Steering

    Recorded in 17.3% of failed Hyundai i40 MOTs. Rare on young cars, but 8.5% of tests at 10–15 years failed on steering.

    The steering should feel precise, without knocks or play, and the car should run straight. Turn to full lock both ways and listen for clunks.

Check the car’s own MOT history. Averages describe the model, not the car in front of you. Look up its registration for past failures, advisories that were never fixed, and gaps or dips in the recorded mileage.

Ask for the service history. Invoices show what was done and when; a stamp alone shows less. See how to check Hyundai service history and what a service history check can tell you.
