Check a Kia Rio advert (free) →The Kia Rio has 2 known faults in our database, 0 of them rated high severity. The most serious are gearbox (two owners of 2013 Rios reported the clutch failing early) and brakes (two owners reported the handbrake failing to hold). 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.
One owner each, in their own words rewritten as a line, and not counted in our risk scoring. A fault joins the list above once a second report or an editorial source backs it.

They do not tell you whether this particular car has had the work: for that, put the registration into the free GOV.UK MOT history check, which shows a recall status where the manufacturer shares it, or ask a franchised dealer to check the VIN.
On some Rio models the child locks on the rear doors may not operate; this is caused by the incorrect length release lever cable being installed.
Put right by: Replacement cable of correct length will be fitted to affected vehicles.
Recall data published by the Driver and Vehicle Standards Agency under the Open Government Licence v3.0. A recall listed here may not apply to every car of this model: the build dates and the registration check are what decide it.
A timing chain has no change interval, which is not the same as lasting for ever. Listen for it on a used Rio, and check the oil has been changed on time. These are the figures UK specialists work to.
The U2-series 1.6/1.7 CRDi diesels and the 1.6 GDi petrol are chain driven with no scheduled replacement, despite the 1.6 CRDi often being mis-quoted as a belt. Chain stretch is rare but tensioner failure can occur if the oil is not changed frequently. The 2.0 and 2.2 CRDi are covered by a separate row because only the 2010-on R-series versions are chain driven.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
Ask the seller about the gearbox and brakes faults on this page and whether they have been fixed, with invoices. On the test drive watch for clutch slipping, with revs rising but little extra speed and car creeping or rolling with the handbrake on. 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 Kia Rio advert →
The DVSA lists 1 safety recall for the Kia Rio issued in 2018. The most recent, from May 2018, is "Child locks on the rear doors may not operate". Recall work is done by the manufacturer, and GOV.UK says you will not usually have to pay for it. This list is by model, so it cannot tell you whether one particular car has had the work: the free GOV.UK MOT history check shows a recall status from the registration where the manufacturer shares it, and a franchised dealer can check the VIN.
Owners report 48.9 mpg on average across the Kia Rio engines with data, about 81% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 859 owner submissions. Kia Rio Real MPG by engine →
