In 2025, 46,733 Hyundai Ioniq cars had a regular MOT in Great Britain. 86% passed first time, compared with 84% for all cars of the same ages, which makes the Ioniq about average. Adjusted for age, it ranks 103 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 3 years old, 85% of Ioniqs passed first time (all cars that age: 88%). By 9 years, that figure is 86% (all cars: 75%). It is weaker than average when young but holds up better than most from around 7 years.

What fails most on a Hyundai Ioniq
No single area stands out: the Ioniq fails on each part of the test at roughly the rate you would expect. It does comparatively well on suspension and body and structure.

What to check when buying a used Ioniq
Based on where the Ioniq fails more often than other cars, these are the checks worth making before you buy:
- Tyres: Check tread across the whole width (uneven wear hints at alignment or suspension faults), and look for cuts, bulges and mismatched brands. Repair guide
- Visibility: Check the windscreen for chips in the driver’s view, the wipers for smearing and the washers for working jets. Repair guide
- Brakes: Look through the wheels for lipped or scored discs, check the handbrake holds on a slope, and feel for pulling or vibration under firm braking. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
