Hyundai I40 years to avoid: the later ones

Based on 21,194 real MOT tests from DVSA records. Each year is compared against every other car first registered the same year — otherwise the numbers would only tell you that older cars fail more, which you knew.

The short answer

Avoid 2018. The worst is the 2018, which fails its MOT 33% more often than other cars of the same age.

Found a Hyundai I40 you like?

Averages tell you what to expect. Its registration tells you what actually happened — every MOT, every advisory, and whether the mileage adds up.

Every I40 model year

Shaded rows are the years that differ most from other cars of the same age — worse, better.

How this is worked out

Every MOT test recorded by DVSA in 2023 on a Hyundai I40, grouped by the year the car was first registered. Retests are excluded, so a car that failed and was fixed still counts as a failure. Each year's rate is then divided by the rate for all cars first registered that year — so 120 means 20% more failures than its contemporaries, not 20% more than a brand new car.
