Renault Koleos common problems and MOT failures

What goes wrong on a used Renault Koleos, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 12,362 MOTs done during 2023–2025), and what to check before you buy one.

The 2021 Renault Koleos

Too few Renault Koleos cars first registered in 2021 had an MOT during 2025 for reliable MOT figures. There are no known faults on record for this year in the UK buying guides we use, so the rest of this page covers the Renault Koleos as a whole.

What to check on a 2021 car
  • MOT history

    Check the reg below: its MOT history shows what has been failed or advised, and whether the mileage adds up.

  • Service history

    Look for regular servicing and receipts for big jobs like a cambelt or clutch.

  • Finance and write-offs

    MOT records don’t show outstanding finance or insurance write-offs. A history check does.

  • Test drive

    Listen for knocks over bumps, check every warning light goes out, and make sure the gears and brakes feel right.

Other years

Most years have their own guide. The year is when the car was first registered (it’s on the logbook, or check the reg below).

Questions to ask the seller before buying a Renault Koleos

Ask before you travel to see it. A seller who knows the car will have answers, and receipts.

  1. Any recent work on the suspension arm bushes and joints? (Flagged at MOT 3.5× as often on the Renault Koleos as on other cars the same age.)
  2. Any recent work on the brake pads? (Flagged at MOT 2.2× as often on the Renault Koleos as on other cars the same age.)
  3. Any recent work on the track rod ends? (Flagged at MOT 5× as often on the Renault Koleos as on other cars the same age.)
  4. Can I see the service history and receipts for any big jobs?

Where this comes from: MOT figures are the DVSA’s anonymised results for every MOT test done in Great Britain during 2023–2025, grouped by the year each car was first registered. How many are on the road is from the Department for Transport’s vehicle licensing statistics. Known faults are from UK buying guides, in our own words, with links. How we score
