Seat Aronas aged 5 to 6 doing under 5,000 miles a year failed first time in 11.6% of tests, against 22.5% for those doing 8,000 to 12,000 miles (2019–2024, n = 11,398).

Seat Aronas aged 5 are forecast to keep taking MOTs for at least 1.0 more years; the survival curve is observed only until age 7, so the true figure is likely higher.

17.5% of Seat Aronas that failed an MOT failed the next one too, against 13.6% after a pass (2019–2024, n = 2,521). The failure most likely to come back is steering: 21.1% of those fails recurred at the next MOT.

Of every 100 Seat Aronas tested at age 5, about 14 failed the MOT first time; at age 7, about 28 (rough estimate). These are one-year rates for different cars tested in the same year, not a fleet followed over time; the steepest one-year step in this cross-section is between cars aged 5 and 6, 8.42 percentage points (2024).

In the Netherlands, 30.9% of Seat Aronas failed their periodic roadworthiness inspection, against 50.8% for all cars there (2024 by country, n = 5,964 inspections).
Both readings are shown: this comparison changes when usage or inspection rules differ.
Inspections abroad disagree: none point the same way as Britain, Finland and the Netherlands do not. Test rules, climate and how the vehicles are used differ, so both readings are shown.

How the MOT Risk Index and every figure on this page are calculated: methodology.
What is wrong on this page? One tap sends the category only, no text and nothing about you.
85.0% of first attempts passed in 2024 (50,672 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.
Other sites may count retests or all attempts. This page uses 50,672 primary tests: 14.96% failed first time and 87.4% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 102.2 is shown separately.
