Kia Ev6 S MOT pass rate & common failures
The Kia Ev6 S appears in 2,419 MOT tests spanning model years 2021–2025, and 94.1% of them passed. All cars of a similar age fail 8.1% of the time, so this is 2.2pp better than the group it competes with. Its most common failure areas are tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.9%) and visibility (3.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, wipers and headlamp aim — tread depth alone was recorded 86 times.
Mileage matters less than usual here: the Ev6 S fails 4.8% of the time in the 0-30k band and 6.5% at 60-90k, a spread of only 1.7 points.
Tyres is the most common advisory, noted on 17.6% of tests — work that passed today but is likely due soon.

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 | 1,529 | 4.8% |
| 30-60k | 801 | 7.9% |
| 60-90k | 77 | 6.5% |
Failure rate by age

What to check before buying a Kia Ev6 S
- Tyres (3.9% 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 (3.3% 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 (0.9% 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.
