2019 Hyundai i30 — MOT failures & pass rate
18,249 MOT tests on the 2019 Hyundai i30 are in this dataset, and 91.0% of them passed. That is effectively the same as small family cars of a similar age (9.6% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (5.3%) and visibility (3.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tread depth and headlamp aim — wipers alone was recorded 483 times.
Mileage is the strongest signal on the record: 6.8% of 0-30k cars fail, rising to 30.8% once past 150k — 4.5× the risk.
The petrol cars hold up better: 8.8% fail against 10.5% for diesel, a 1.7-point gap across 18,249 tests.
Tyres is the most common advisory, noted on 23.0% of tests — work that passed today but is likely due soon.
The trend is worsening — 8.3% of tests failed in 2021 against 10.3% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2019 i30
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.3% of tests. Start there.
- Tyres (5.3% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (3.2% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Lighting & signalling (1.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
