2023 Hyundai Ioniq — MOT failures & pass rate
674 MOT tests on the 2023 Hyundai Ioniq are in this dataset, and 96.0% of them passed. That is 1.6 percentage points better than small family cars of a similar age, which fail at 5.6%. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.3%) and lighting & signalling (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and tread depth — wipers alone was recorded 11 times.
Mileage is the strongest signal on the record: 1.8% of 0-30k cars fail, rising to 6.5% once past 60-90k — 3.6× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 8.8% of tests without failing them.
The trend is worsening — 0.0% of tests failed in 2023 against 5.9% in 2025, the usual pattern as a fleet ages.

| Fuel | Tests | Fail rate |
|---|---|---|
| Electric | 575 | 4.0% |
| Hybrid | 99 | 4.0% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2023 Ioniq
On a 2023 Ioniq, tyres is what the MOT record says goes wrong most — it appeared in 3.3% of tests. Check these areas before you commit.
- Tyres (3.3% 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.
- Lighting & signalling (2.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.5% 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.
