Renault Koleos reliability: MOT pass rate and common faults

1,000 initial MOT tests in 2025 on cars first used in 2019 · DVSA data · For guidance only · How we count

Renault Koleos cars first used in 2019 had an MOT pass rate within the margin of error of the average for their age.

The MOT pass rate is one signal, not the whole story. An MOT checks safety and emissions on the day of the test. It doesn't record gearbox or engine faults, and a pass rate also reflects mileage and upkeep, so the table shows median mileage too. Whatever the year, the car in front of you matters more than its model's average.

First-time pass rate, all years together: initial tests passed with no repairs. 95% range 79.6% to 84.4%.

Renault Koleos, all years82.1%

In 2025, 82.1% of the 1,000 initial MOT tests on Renault Koleos cars were passed with no repairs. The same-age average, for all vehicles first used in the same years, was 83.5%. That is about average: the difference from the same-age average is within the margin of error.

Renault Koleos MOT pass rate by year

Year is when the car was first used. Older vehicles fail more often, so each year is compared with all vehicles first used that year.

Tests are initial MOT tests in 2025, not retests. Median miles is the middle odometer reading at the test: half had more, half had less. ± is the 95% margin of error in points (Wilson interval): a difference smaller than that could be chance. Years without a link have fewer than 10,000 tests, so they are listed here but don't have their own page.

What to check when viewing a Koleos

Based on the areas where Renault Koleos MOT tests fail most often. These are general checks anyone can do, not a mechanical inspection.

Brakes
In 29.6% of failed Koleos tests
- On a clear road, brake firmly and check the car stops in a straight line without juddering or pulling to one side.
- Check the handbrake holds the car on a slope.
- Look through the wheels at the brake discs for deep grooves or a raised lip at the edge.
Noise, emissions, leaks
In 28.5% of failed Koleos tests
- Ask to see the car start from cold. Heavy smoke from the exhaust is worth asking about.
- Listen for blowing or rattling from the exhaust with the engine running.
- Look under the car for drips of oil, coolant or other fluids.

Then read the car's own MOT history. Advisories in the same area at several tests are worth asking about.
