Should I check the MOT history before buying a 2021 Audi RS Q3 Sport Ed TFSI Quattro SA?

How are tyres and brakes typically on a 2021 Audi RS Q3 Sport Ed TFSI Quattro SA?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Do I need an HPI check when buying a 2021 Audi RS Q3 Sport Ed TFSI Quattro SA?

Moderate sample. 361 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 Audi RS Q3 is proving to be a genuinely reliable performer, with a 91.9% first-time pass rate that sits well clear of the UK average of 80%—and only 5.3% of vehicles have ever recorded a dangerous defect, which is reassuringly low. There's no meaningful variation to worry about here since the cohort is overwhelmingly petrol (356 of 361 cars), so you're looking at consistent results across the board.

At just under 27,000 miles median age-appropriate mileage, these cars are running light, and the average of only 0.16 failures per vehicle tells you major mechanical problems are rare on this model. The 1.0 advisory per vehicle is typical wear-and-tear territory; to buy confidently, get a pre-purchase inspection focused on turbo health and the dual-clutch gearbox, which are the RS Q3's high-stress components.

The 2021 Audi RS Q3 Sport Ed TFSI Quattro SA passes its MOT first time more often than most UK vehicles (94.8% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 94.8% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 361 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
