2021 Kia Ev6 S — MOT failures & pass rate
The 2021 Kia Ev6 S passed 92.3% of its 1,010 recorded MOT tests. All cars of a similar age fail at 8.7%, so the 2021 Ev6 S sits squarely on the average. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (5.1%) and visibility (4.0%) 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 50 times.
Advisories point at the next bill rather than this one: tyres was flagged on 18.8% of tests without failing them.

| 6 | Suspension | 0.1% | 1 |
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 | 599 | 5.8% |
| 30-60k | 378 | 10.6% |
Failure rate by age

What to check before buying a 2021 Ev6 S
On a 2021 Ev6 S, tyres is what the MOT record says goes wrong most — it appeared in 5.1% of tests. Check these areas before you commit.
- Tyres (5.1% 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 (4.0% 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.
- Lighting & signalling (0.8% 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.
