Renault Clio MOT Failures
An analysis of 3,748,884 real DVSA MOT tests on the Renault Clio — what fails, how often, and how that compares to every other car on UK roads. Generations covered: Mk2 Ph1 (1998–2001), Mk2 Ph2 (2001–2005), Mk3 (2005–2009), Mk3 FL (2009–2012), Mk2 (1998–2012), Mk2 RS (2003–2011), Mk3 (2005–2014), Mk4 (2012–2019), Mk1 (1990–1998), Mk5 (2019–2024).
Where the Renault Clio fails its MOT
The single biggest MOT failure point on the Renault Clio is headlight fault — this model is 30 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 3,748,884 MOT tests, 3.5% of all Renault Clio tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include external damage (43x the fleet average), emissions failure (63x the fleet average), brake servo failure (76x the fleet average), and airbag fault (246x the fleet average). These ratios compare the Renault Clio's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 6 categories: Lights & Electrics, Brakes, Exhaust & Emissions, Seatbelts & Airbags, Suspension and others. If you're inspecting a Renault Clio before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Renault Clio's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Renault Clio specifically, the DVSA data shows the most common failures at this mileage are brake servo failure (43x the average) and external damage (43x). emissions failure (33x) and stop lamp missing, inoperative or in the case o... (31x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Renault Clio specifically, the DVSA data shows the most common failures at this mileage are airbag fault (246x the average) and emissions failure (51x). brake servo failure (32x) and external damage (31x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Renault Clio specifically, the DVSA data shows the most common failures at this mileage are anti-roll bar links worn (113x the average) and airbag fault (110x). emissions failure (63x) and brake servo failure (55x) also appear frequently.
The shift from brake servo failure at lower mileages to anti-roll bar links worn at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Renault Clio specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Bonnet catch failure (safety) (Phase 1/2) Dangerous
The bonnet catch mechanism on Phase 1/2 Clios suffers from internal spring failure and striker wear, causing the bonnet to appear closed while not being properly secured. Affects Phase 1/2; typical independent garage repair cost is £20–£60.
Timing belt and dephaser pulley failure (Phase 1/2) Dangerous
The F4R 2.0 16v engine uses an interference design where timing belt failure causes immediate and total engine destruction. Affects Phase 1/2; typical independent garage repair cost is £400–£600.
Ball joint and track rod end wear Dangerous
MOT data shows Clios fail for steering component wear at 33-2332.5 times the national fleet average, with damaged or missing dust covers being a particular problem. Affects Mk2, Mk3, Mk4; typical independent garage repair cost is £200–£400.
Cambelt and dephaser service (Mk3) Dangerous
The F4R engines use an interference design where timing belt failure causes total engine destruction through piston-valve contact. Affects Mk3; typical independent garage repair cost is £400–£700.

What to check before buying a Renault Clio
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Renault Clio:
Lights & Electrics — check for headlight fault. Brakes — check for external damage, brake servo failure. Exhaust & Emissions — check for emissions failure.
Beyond the MOT items, ask specifically about bonnet catch failure and timing belt and dephaser pulley failure. These won't show up on a standard MOT but can be expensive to fix — repairs start from £20. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
