2019 Hyundai Ioniq — MOT failures & pass rate
The 2019 Hyundai Ioniq passed 91.5% of its 44,960 recorded MOT tests. That is effectively the same as small family cars of a similar age (9.5% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (4.2%) and lighting & signalling (3.7%) 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 1,473 times.
Mileage matters less than usual here: the 2019 Ioniq fails 6.6% of the time in the 0-30k band and 10.6% at 150k+, a spread of only 4.0 points.
Fuel type barely separates them — electric fails 7.5% of the time against 8.6% for hybrid.
Tyres is the most common advisory, noted on 18.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 4.4% of tests failed in 2021 against 9.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 Ioniq
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.2% of tests. Start there.
- Tyres (4.2% 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.
- Lighting & signalling (3.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (3.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
