Should I check the MOT history before buying a 2021 Renault Kadjar?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Renault Kadjar?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Renault Kadjar?

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.

The 2021 Renault Kadjar is a strong performer in the MOT, with a 92% first-time pass rate that beats the UK average of 80% by a clear margin. Only 8.1% have ever recorded a dangerous defect, which is reassuringly low, and petrol versions edge out diesels slightly at 92.3% versus 88.7% pass rates.

These cars are still young with a median mileage of 24,753, so the low failure count of 0.27 per vehicle reflects normal wear rather than long-term durability proof. The 1.9 advisories per vehicle suggest minor issues are emerging (suspension, lights, and trim wear typical for three-year-olds), so budget for small consumables—but if you're buying one, insist on a full pre-purchase inspection to catch any electrical gremlins before they become expensive.

The 2021 Renault Kadjar passes its MOT first time more often than most UK vehicles (92% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 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 92% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 1.9 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 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 1,499 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.
