This 2021 Audi Q3 is substantially more reliable than the UK average, with a 95.9% first-time MOT pass rate against the typical 80%—very few buyers of this model encounter serious test failures. The dangerous defect rate sits at a low 5.0%, so safety concerns are minimal for the cohort.

At just over 33,000 miles median, these cars are lightly used for their age, which partly explains the strong pass rate, though the 0.13 average failures per vehicle suggests the model itself is well-engineered. Advisories average 1.5 per test—routine maintenance items rather than structural problems—so budget for minor upkeep but expect few surprise repairs; when shopping, prioritise a full service history over mileage alone.
