Expert verdict
Brakes: 1.5× the national share
Brakes make up 31.4% of everything recorded on the 2015 Kia Rio, against 20.9% nationally — 10.5 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- When it fails, it costs. Only 26% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

Where the Kia Rio is most common
Across all Rio model years on record (2001–2023): 138,616 Kia Rio cars tested in a recordable postcode area, across 355,407 tests. Birmingham (B) has the most, with 3,732 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Kia Rio cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2015 Rio
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2015 Rio
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the tyre tread 1.8% of tests
“tread depth below requirements of 1.6mm”
Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.
-
Check the suspension joints 1.6% of tests
“track rod end ball joint dust cover damaged or deteriorated,”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
Check tyre pressures and valves 1.4% of tests
“tyre pressure monitoring system malfunctioning or obviously inoperative”
Set the pressures to the figures on the door pillar, not the tyre wall, and check the valves do not hiss. A leaking valve is a two-minute fix that fails a test.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2015 Rio through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £33–£77 — and 26% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

|---|---|---|---|
| Tread depth below requirements of 1.6mm Tyres | Advisory | 17.6% | £45–95 |
| Brake discs in such a condition that it is seriously weakened Brakes | Advisory | 13.3% | £45–110 |

| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 8.9% | £45–95 |
