Fluid leak
The vehicle is leaking a fluid — oil, coolant, fuel or hydraulic. A slight seep is common on older cars; a continuous drip is both a road hazard and a sign of something failing.
MOT wording: Oil leak, but not excessive

What actually goes wrong
What breaks on Hyundai cars
The most common MOT faults across the Hyundai range, in plain English. Models with more MOT tests count for more. The percentage is the share of MOT tests on Hyundai cars that recorded that defect.
17.7%
Tyre condition
A tyre is worn, cut, damaged or otherwise not fit for the road. Tyres are the only thing connecting the car to the road, so this is always worth taking seriously.
MOT wording: Tyre worn close to the legal limit or worn on the edge
17.5%
Rigid brake pipe
A rigid metal brake pipe is corroded, damaged, kinked, or leaking. These permanently fixed pipes carry pressurised brake fluid — any weakness is a serious safety concern.
MOT wording: Brake pipe corroded or covered in grease
14.7%
Suspension arms, struts and anti-roll bar
A suspension arm, wishbone, strut, sub-frame, or anti-roll bar is worn, cracked, bent, or has excessive play. These structural parts hold the wheels in position and control body lean in corners.
MOT wording: Suspension part corroded, but not seriously weakened
Across all Hyundai models; models with more MOT tests count for more.
The whole range
Every Hyundai that ranks, in plain English
For each model, one number: the share of its MOT tests at 7 years old that ended in a fail. Retests count as tests. Lower is better. The UK average (about 1 in 6 MOTs, 16.6%) is shown for reference. Only models with enough MOT data at 7 years old are ranked. The rest sit just below, unranked.

Fail rates are the share of MOT tests on 7-year-old cars ending in a fail, retests included (DVSA MOT results, 2025). UK average across all makes at the same age: 16.6%. How we count fail rates
Not directly comparable with the figures at 7 years old
Shown unranked. These models don’t have enough MOT data at 7 years old yet. They’re either too new (few cars old enough) or too old (few still on the road). Each is shown at the age with the most tests, so the percentages aren’t directly comparable to the list above.
