All generations and engines together · 90,008 MOT tests in the 2025 data · typical mileage at age 7: 52k
Split by first-registration year. Cars registered in a changeover year can belong to either generation.
Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.
Share of tests where each item was recorded. The dark tick is the class average across all tracked models; bars are scaled within each group.
The rows that judge the model rather than its keeper. 30,311 tests in this band.
Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
The Rio is tuned firm, and both reviewers and owners describe it thumping over potholes and feeling crashy at low speed, smoothing out once you're up to motorway pace. That lines up with the measured data too: suspension-related work is this model's standout weak point at MOT time. Most owner complaints are about harsh ride rather than a single failed part, so it reads more as general wear on UK roads than one component to chase.
The 120PS 1.0-litre turbo manual uses an electronically operated clutch actuator (Kia's iMT) instead of a normal cable or hydraulic clutch, and reviewers note it feels clunky and remote compared with a conventional manual. Separately, owners on the Kia Owners Club forum have reported outright clutch/actuator faults needing a garage visit. If the actuator itself needs replacing outside warranty, expect a few hundred pounds. Doesn't apply to other engines, which use a normal clutch.
Several owners of diesel Rios, mostly older 1.4 and 1.5 CRDi cars, report intermittent power loss under load: boost falling away above roughly 2,000rpm, or the car briefly cutting out with no warning light, sometimes needing an ECU reset at a garage to clear. It reads as a turbo/VNT actuator or fuelling gremlin rather than one specific failure everyone hits. Fixes range from a cheap reset up to turbo repair or replacement, which can run into four figures if the actuator or whole unit needs swapping.
Owners occasionally report the touchscreen blanking out along with the reversing camera, indicator bulbs or wiring sticking on, and a handful of 1.25 petrol cars struggling to start in freezing temperatures. None of this is systemic enough to be a manufacturer campaign, but it comes up often enough on the owners' forum to be worth checking before you buy. Cost is usually low, a bulb or a reset, but a full head unit swap is more, roughly £150-£400 at an independent.
One parts-trade write-up on common Rio faults flags timing chain and tensioner wear on the 1.0-litre turbo from as early as 40,000-60,000km (roughly 25,000-37,000 miles), causing a rattle on cold start-up and, if ignored, a loss of power. We couldn't stand this up against a second independent source, so treat it as something to listen for rather than a confirmed pattern. A chain and tensioner job runs to a few hundred pounds; letting it go and damaging the engine costs a lot more.
