Kia Ev6 MOT pass rate & common failures
Across 5 model years and 3,392 tests, the Kia Ev6 passes its MOT 93.9% of the time. Against all cars of a similar age (7.9% fail rate), the Ev6 comes out 1.8pp better. Its most common failure areas are visibility, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — visibility (4.4%) and tyres (3.5%) 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 161 times.
Mileage matters less than usual here: the Ev6 fails 5.3% of the time in the 0-30k band and 7.2% at 60-90k, a spread of only 1.9 points.
Tyres is the most common advisory, noted on 16.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 0.0% of tests failed in 2023 against 6.4% 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.

Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 1,709 | 5.3% |
| 30-60k | 1,453 | 7.0% |
| 60-90k | 193 | 7.2% |
Failure rate by age
Trend over time

What to check before buying a Kia Ev6
- Visibility (4.4% 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.
- Tyres (3.5% 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 (1.2% 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.
