Moderate sample. 383 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 Hyundai i30 N Line MHEV is reliably clearing its MOTs, with an 88.9% first-time pass rate that comfortably beats the UK average of 80%. Dangerous defects are relatively uncommon at 10.4%, so serious safety issues aren't a typical concern with this model.

These vehicles are running at modest mileage for their age (27,418 miles median), suggesting they're being used normally rather than thrashed. The low failure rate of 0.32 per vehicle means most owners won't face expensive repairs at test time, though the 2.0 advisories per car indicate minor maintenance items are cropping up—check brake wear, fluid levels, and suspension play when you view one.

The 2021 Hyundai I30 N Line MHEV T Gdi passes its MOT first time more often than most UK vehicles (89.8% 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 89.8% 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 2 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 383 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.
