Is the Renault Koleos reliable?
The Renault Koleos has 2 known faults in our database, 1 of them rated high severity. The most serious are suspension (DVSA recall R/2009/109, launched in November 2009 for 2,774 Koleos) and engine (the 2.0 dCi's diesel particulate filter struggles to regenerate and blocks). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
Which Renault Koleos years should you avoid?
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.

Renault Koleos Mk1 (2008 to 2010) problems
Engine/EmissionsMedium severity📝 Editorial
The 2.0 dCi's diesel particulate filter struggles to regenerate and blocks. Renault issued a technical bulletin in October and November 2011 to reprogram the engine ECU, believed to help the filter regenerate more effectively, and a 2017 report describes a 75,000 mile 2008 car showing a check exhaust emission warning with very little power after four long fast runs, thought to be the filter finally filling with ash.
Rough guide
£300-1500
Typical symptoms
check exhaust emission message with the engine and spanner symbols lit
sudden loss of power or limp mode

DVSA recall R/2009/109, launched in November 2009 for 2,774 Koleos, covers the steering column mounting nut on the steering rack, which may work loose and let the column come out of position, with a loss of steering control. The archive linked it to the matching Qashqai and X-Trail recall, as the Koleos uses basically the same components. The remedy is free at a Renault dealer.

Renault Koleos buying questions
Which Renault Koleos years should I avoid?
No Renault Koleos year is a write-off, but the Mk1 (2008 to 2010) carries the most serious faults: suspension. Year matters less than whether the specific car has had the known fixes, so check the history for them.
What should I check when viewing a used Renault Koleos?
Ask the seller about the suspension and engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for knock or free play in the steering and check exhaust emission message with the engine and spanner symbols lit. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against its known faults before you travel. Check a Renault Koleos advert →
