Is the Suzuki Alto reliable?

On MOT evidence the Suzuki Alto is well below average. It passes 58.8% of tests once age and mileage are accounted for, against a national average of 72.3%. That figure covers 61% of the national age and mileage range, which is enough to quote but not to rank. This measures how often the car meets the MOT standard, not how often it breaks down or what a repair costs.

What is the most common MOT failure on a Suzuki Alto?

The item recorded most often is "Brake pipe damaged or excessively corroded", which appears in 20.8% of failed Suzuki Alto tests. Because one failed test can list several items, these shares do not add up to 100%.

What do testers most often warn about on a Suzuki Alto?

The most common advisory is "Brake pipe damaged or excessively corroded", noted on 33.0% of all Suzuki Alto tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Suzuki Alto usually have at its MOT?

The average odometer reading recorded at test is 62,265 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.

Does a Suzuki Alto get harder to pass as it ages?

Yes. At 9 to 11 years old, 68.3% of Suzuki Alto tests pass. By fifteen years or more, that falls to 58.4%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

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.
