101,999 i30s had an MOT in 2025. 64.6% passed first time, against 69.1% for other cars of the same age and mileage. Most of the gap comes from cars registered from 2007 to 2014, which fail on brakes 1.8 times as often as comparable cars. Those registered from 2020 onwards pass as often as other cars their age.
Each dot compares how often i30s of that year failed on one area of the test with cars of the same age and mileage.

Much worse: failed on that area at least 1.5 times as often. Worse: 1.15 to 1.5 times. Better: up to 0.87 times. Much better: two-thirds as often or less. Gaps under half a percentage point count as about the same. Registration year is the year the car was first used.
Well behind: 5 or more points below cars of the same age and mileage. Behind: 1.5 to 5 points below. Level: within 1.5 points. Ahead: 1.5 or more points above.
5.8% of i30 MOTs failed on steering, against 2.3% for cars of the same age and mileage, and 11.9% on brakes, against 6.8%.
Up to 60,000 miles, i30s pass as often as cars of the same age and mileage. Behind from there: 60–90,000 miles 4.2 points, 90–120,000 miles 6.5 points, 120,000+ miles 9.5 points.
Diesels passed 60.3% first time, 6.2 points below comparable cars; petrols passed 67.6%, 3.1 points below comparable cars. Diesels had a median of 91,568 miles at the test, against 67,094 for petrols. Hybrids are mostly newer cars (median 29,576 miles), so compare them with care.

Data. Every car MOT in Great Britain in 2025 (31,475,521 first tests on cars first used 2005 to 2022), from DVSA's anonymised MOT test data. Retests are left out.
Passed first time. A car passed if its first test that year ended in a pass. Cars that failed and were fixed within the hour count as fails, as DVSA counts them.
Same age and mileage. We group every car by the year it was first used and its mileage (under 30k, 30–60k, 60–90k, 90–120k, over 120k). The comparison figure is what those groups scored, weighted to match the i30's mix of ages and mileages.
Model. Every car DVSA records as a Hyundai i30: 26 recorded model names, from "I30" to trims such as "I30 N LINE MHEV T-GDI".
