Buying a used Renault Koleos
The Renault Koleos passed 77.61% of its 3,211 initial MOT tests in 2025 — about the same as the 77.3% average for all cars. That tells you about the model. It tells you nothing about the specific car you are looking at, which is where the expensive surprises live.

What the MOT data shows about the Renault Koleos
Ranked on pass rate, the Renault Koleos sits 371 of 651 models in this data. Renault as a marque averaged 67.86%, so this model runs 9.8 points ahead of its own brand. A pass rate is not a reliability score — it records whether cars met the roadworthiness standard on test day.
How age affects a used Renault Koleos
This matters more than the headline figure when you are buying: it shows what happens to this model as it gets older.
| Age at test | Tests | Pass rate |
|---|---|---|
| 3–5 years | 17 | 94.12% |
| 6–10 years | 2,354 | 84.62% |
| 11 years and over | 840 | 57.62% |
The Renault Koleos gives up 36.5 percentage points between its early years and the 11-plus bracket. On an older example, budget for the MOT and read the car's own test history closely before agreeing a price.

What the MOT record will not tell you
Knowing that Renault Koleos failures cluster around suspension and brakes tells you what to inspect. It tells you nothing about whether the car is legally safe to buy. An MOT records that a car met a minimum standard on the day it was tested. It does not check the engine, clutch or gearbox, and it says nothing at all about the car's legal and financial history. On a 9.3-year-old average example those are the risks that cost real money:
- Outstanding finance. If money is still owed against the car, the lender may retain an interest in it after you have paid the seller.
- Insurance write-off history. A recorded Cat S or Cat N marker is permanent and affects safety, insurance and resale — and it does not appear on the V5C.
- Stolen markers. A vehicle recorded as stolen can be seized even from a buyer who bought it in good faith.
- Mileage history. Recorded readings that do not move consistently between tests are the clearest sign of a clocked car.
- Previous keepers. An unusual number of owners for the age of the car is worth asking about.
A Carpeep car history check reports all of those against the registration, plus tax status, import and export markers, scrapped status and the vehicle identity details, in one £15 report.

Used Renault Koleos FAQs
What should I check before buying a used Renault Koleos?
Check the individual car rather than the model: outstanding finance, insurance write-off records, stolen markers, mileage history and the number of previous keepers. None of these appear on the V5C or in the MOT record, and a seller does not have to volunteer them. On the model itself, DVSA data for 2025 shows the Renault Koleos passed 77.61% of its initial MOT tests.
Is the Renault Koleos reliable?
MOT data does not measure reliability, it measures whether a car met the roadworthiness standard on the day of its test. What it does show for the Renault Koleos is a 77.61% first-time pass rate across 3,211 tests in 2025, which is about the same as the 77.3% average for all cars.
