2021 Kia Ev6 — MOT failures & pass rate
Across 568 MOT tests, the 2021 Kia Ev6 recorded a 94.9% pass rate. All cars of a similar age fail 8.6% of the time, so this is 3.5pp better than the group it competes with. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.0%) and visibility (2.1%) 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 attachment — wipers alone was recorded 11 times.
Mileage matters less than usual here: the 2021 Ev6 fails 4.3% of the time in the 0-30k band and 6.5% at 60-90k, a spread of only 2.2 points.
Advisories point at the next bill rather than this one: tyres was flagged on 16.4% of tests without failing them.

What to check before buying a 2021 Ev6
On a 2021 Ev6, tyres is what the MOT record says goes wrong most — it appeared in 3.0% of tests. Check these areas before you commit.
- Tyres (3.0% 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 (2.1% 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.
