Should I check the MOT history before buying a 2021 Kia Sportage GT Line CRDI Isg MHEV?

This 2021 Kia Sportage is a strong performer, with an 89.4% first-time pass rate that sits well clear of the UK average of 80%, suggesting the hybrid diesel powertrain is holding up reliably so far. The 9.2% dangerous defect rate is low enough not to be a concern for buyers.

At just over 32,500 miles median mileage, these vehicles are still relatively young and lightly driven, which explains the modest 0.29 failures per car and 1.7 advisories per car on average. Before buying, check the service history carefully and have a pre-purchase inspection focus on the hybrid system components, as the advisory rate suggests minor wear items are appearing even at this low mileage.

The 2021 Kia Sportage GT Line CRDI Isg MHEV passes its MOT first time more often than most UK vehicles (91% 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 91% 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 1.7 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 1,224 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.
