Expert verdict
Advisories: 3.3× the national share
Advisories make up 13.9% of everything recorded on the 2018 Renault Koleos, against 4.2% nationally — 9.7 points above. Brakes are still the single largest share at 30.1%, but at 20.9% nationally that one is ordinary. Most of what testers record here is advisory — worth reading, not worth walking away from on its own.
- When it fails, it costs. Only 27% 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 Renault Koleos is most common
Across all Koleos model years on record (2008–2020): 6,751 Renault Koleos cars tested in a recordable postcode area, across 14,578 tests. Sheffield (S) has the most, with 178 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 Renault Koleos 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 2018 Koleos
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 2018 Koleos
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 brakes 1.8% of tests
“brake pads less than 1.5 mm thick”
Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.
-
Check the suspension joints 1.5% of tests
“ball joint excessively worn”
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 the windscreen 1.2% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
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 2018 Koleos through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £28–£71 — and 27% of those repairs are parts that cost under £30.

What testers noted without failing the car

| Tread depth below requirements of 1.6mm Tyres | Advisory | 16.9% | £45–95 |
