Exhaust: 3.6% of tests fail on emissions & leaks, against 2.5% for a typical car of the same age and mileage. Listen for a blowing exhaust at start-up and look underneath for oil or fluid leaks.Suspension: 4.8% of tests fail on suspension, against 7.4% for a typical car of the same age and mileage. Listen for knocks over speed bumps and push each corner down: it should settle at once.Lights: 22.6% of tests fail on lights & electrics, against 10.3% for a typical car of the same age and mileage. Walk round the car with every light on, including brake, fog and number plate lights.Tyres: 6.3% of tests fail on tyres, against 6.9% for a typical car of the same age and mileage. Check the tread on every tyre, including the inner edge, and look for cuts or bulges.Brakes: 13.7% of tests fail on brakes, against 6.0% for a typical car of the same age and mileage.

How we calculate this. We use official MOT results for cars tested in Great Britain from 2018 to 2026. Each car is compared with typical cars of the same age and mileage, so old and new cars are judged fairly; “pts” are percentage points above or below them. Differences also reflect how cars are used and maintained, not only how they are built.
