The 2018 Hyundai i20 is a reliable performer, with a first-time MOT pass rate of 90.3% that sits meaningfully above the UK average of 80%—this is a car that tends to stay in decent working order. The dangerous defect rate of 14.2% is low enough that it shouldn't deter buyers, though it's worth checking the specific failure history of any individual example you're considering.
At a median mileage of 30,045 miles for a six-year-old car, these vehicles have been run relatively gently, which explains the strong pass rates and low failure count of just 0.65 per vehicle. When failures do occur, they're typically minor; the average of 4.3 advisories per test suggests routine wear items like brakes and bulbs rather than structural problems—get a pre-purchase inspection to confirm service history and check for any pattern of electrical gremlins.
The 2018 Hyundai I20 passes its MOT first time more often than most UK vehicles (90.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 8,662 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.
