Toyota Aygo MOT Failures
An analysis of 6,402,015 real DVSA MOT tests on the Toyota Aygo — what fails, how often, and how that compares to every other car on UK roads. Generations covered: XP10 (2005–2014), XP20 (2014–2022).
Where the Toyota Aygo fails its MOT
The single biggest MOT failure point on the Toyota Aygo is anti-roll bar links worn — this model is 21 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 6,402,015 MOT tests, 1.6% of all Toyota Aygo tests recorded this as a failure.
Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.
Other notable weak points include light unit fault (32x the fleet average), track rod ends worn (13x the fleet average), subframe bushes or mounts worn (12x the fleet average), and mandatory tell-tale for direction indicators or... (73x the fleet average). These ratios compare the Toyota Aygo'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 5 categories: Suspension, Lights & Electrics, Steering, Brakes, Bodywork. If you're inspecting a Toyota Aygo 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 Toyota Aygo'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 Toyota Aygo specifically, the DVSA data shows the most common failures at this mileage are mandatory tell-tale for direction indicators or... (28x the average) and hazard warning lamp tell-tale is not a flashing... (21x). light unit fault (11x) and indicator or hazard warning switch inoperative (10x) 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 Toyota Aygo specifically, the DVSA data shows the most common failures at this mileage are light unit fault (30x the average) and hazard warning lamp tell-tale is not a flashing... (28x). mandatory tell-tale for direction indicators or... (28x) and anti-roll bar links worn (18x) 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.

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 Toyota Aygo specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion affecting steering and braking safety Dangerous
MOT data shows Aygos fail structural integrity tests at 8.5 times the national fleet average, specifically for corrosion that affects steering or braking systems. Affects XP10, XP20; typical independent garage repair cost is £300–£800.
Suspension component excessive wear and corrosion Major
MOT data shows Aygos fail suspension component tests at rates up to 32 times the national average, particularly for worn bushes, joints, and corroded components. Affects XP10, XP20; typical independent garage repair cost is £150–£400.
Excessive blue or black smoke emission (XP10/XP20) Major
MOT data shows petrol Aygos fail smoke emission tests at 15.8 times the national average, particularly on higher mileage examples. Affects XP10, XP20; typical independent garage repair cost is £400–£1,500.
Emissions system lambda sensor and catalytic converter failure Major
MOT data shows petrol Aygos fail emissions tests at rates 9.6-13.5 times higher than the national average, with lambda coefficient and general emissions limit failures. Affects XP10, XP20; typical independent garage repair cost is £150–£600.

What to check before buying a Toyota Aygo
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Toyota Aygo:
Suspension — check for anti-roll bar links worn, subframe bushes or mounts worn. Lights & Electrics — check for light unit fault, mandatory tell-tale for direction indicators or..., hazard warning lamp tell-tale is not a flashing.... Steering — check for track rod ends worn.
Beyond the MOT items, ask specifically about structural corrosion affecting steering and braking safety and suspension component excessive wear and corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £300. 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.
