2022 Kia Rio — MOT failures & pass rate
The 2022 Kia Rio passed 94.0% of its 5,153 recorded MOT tests. Superminis of a similar age fail at 6.9%, so the 2022 Rio sits squarely on the average. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.4%) and visibility (2.2%) 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 brake pads — wipers alone was recorded 84 times.
Mileage is the strongest signal on the record: 4.4% of 0-30k cars fail, rising to 16.0% once past 60-90k — 3.6× the risk.
Fuel type barely separates them — hybrid fails 5.1% of the time against 6.5% for petrol.
Advisories point at the next bill rather than this one: tyres was flagged on 11.6% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 11.6% | 599 |
| 2 | Brakes | 6.9% | 353 |

| 5 | Lighting & signalling | 0.7% | 35 |
| 6 | Emissions & environmental | 0.4% | 22 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

|---|---|---|
| 0-30k | 3,853 | 4.4% |
| 30-60k | 1,190 | 10.5% |
| 60-90k | 100 | 16.0% |

By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Petrol | 3,620 | 6.5% |
| Hybrid | 1,532 | 5.1% |

What to check before buying a 2022 Rio
On a 2022 Rio, tyres is what the MOT record says goes wrong most — it appeared in 3.4% of tests. Check these areas before you commit.
- Tyres (3.4% 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 (2.2% 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 (1.9% 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.
