Is the Toyota Aygo reliable?

On MOT evidence the Toyota Aygo is below average. It passes 70.4% of tests once age and mileage are accounted for, against a national average of 72.3%, which ranks it 168 of 262 models with enough data for a fair comparison. This measures how often the car meets the MOT standard, not how often it breaks down or what a repair costs.

What do testers most often warn about on a Toyota Aygo?

The most common advisory is "A tyre seriously damaged", noted on 24.6% of all Toyota Aygo tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Toyota Aygo usually have at its MOT?

The average odometer reading recorded at test is 54,528 miles. This is the mileage across all tested examples of every age, not an annual figure, so treat it as a description of the fleet rather than a target for one car.

Which Toyota Aygo years are the most reliable?

Going by MOT pass rate, Toyota Aygo cars first registered 2020–2022 do best at 88.4%, and those registered 2010 and earlier do worst at 55.5%. But that ordering is mostly age, not build year: almost every model passes less often as it wears, so the newest cars top this list whatever they are. A specific year looking strong here means little on its own; the failure items above, and the individual car's own MOT history, tell you far more.

Does a Toyota Aygo get harder to pass as it ages?

Yes. At 3 to 5 years old, 88.4% of Toyota Aygo tests pass. By fifteen years or more, that falls to 55.5%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Toyota Aygo MOT pass rate & common failures

From 256,983 recorded MOT tests of the Toyota Aygo, published by DVSA.

Data updated 29 July 2026

Quick answer

The Toyota Aygo passes 70.4% of MOT tests once results are adjusted for the age and mileage of the cars tested, against a national average of 72.3%. That is below average, ranking it 168 of 262 models with enough data to compare fairly. Based on 256,983 tests. Its most commonly recorded failure is strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, which appears in 13.1% of failed tests. Cars of this model average 54,528 miles on the odometer when tested.

The Aygo is 1.9 percentage points below the national pass rate once age and mileage are accounted for, which is below average. The unadjusted figure is 74.9%; the difference is what the age and mileage of this model’s fleet was hiding.

Known faults

Toyota Aygo common problems, by part and by year

The same failure record read the way a buyer asks the question: which parts wear out on a Aygo, when they start, and how each registration year compares — including the steps that mark a generation change.

Aygo common problems and results by year

How wear changes the picture

Aygo pass rate by age and registration year

How often the Toyota Aygo passes at each age, with the years those cars were first registered. Tests are from 2025, so a car aged 3 to 5 was first used in 2020–2022.

3–5 yrsreg. 2020–202288%

6–8 yrsreg. 2017–201985%

9–11 yrsreg. 2014–201679%

12–14 yrsreg. 2011–201364%

15+ yrsreg. 2010 and earlier55%

Read this as an age curve rather than a verdict on particular model years. Nearly every car passes less often as it gets older, so a newer Aygo outscoring an older one says more about wear than about how that year’s cars were built. Bands holding too few tests to be meaningful are omitted rather than shown as a rate.

How this was worked out

Method and limits

Figures come from the DVSA anonymised MOT testing dataset, published under the Open Government Licence. Only class 4 initial tests are counted: retests are excluded so a car appears once, and abandoned tests are excluded entirely. The adjusted rate is directly standardised across twenty-five age and mileage bands and reweighted onto the national distribution, so this model is compared against cars that have lived a similar life rather than against a younger or lighter-used fleet.

An MOT measures whether a car met a legal standard on the day. It is not a breakdown record, a service history or a running-cost estimate, and a pass rate is a property of a fleet rather than a prediction about one car.
